To accomplish bit synchronization the conventional technique in Telemetric Sys-tem is to use the same frame synchronization codes derived from the control tation.But this is not so ideal a technique in practice.After a comparison of several typicaldesign ideas it is concluded that the better choice is the method of“frame informationcarried by synchronization codes with information codes carrying bit information”,which has been practiced in Intel 8273 HDLC/SDLC controller for a typical example. However,NRZ_I codes used in 8273 controller have some inherent drawbacks incarrying bit information.In our approach in stead of NRZ_I code system,we haveused Miller Code System,the full advantage of which has for long been being enjoyedin magnetic recording technique.The author has designed the encoding and decoding logic in terms of Miller codesystem.The resultant circuitry is quite simple and those drawbacks inherent in 8273controller have been eliminated.It seems that this new approach will also be advan-tageous to similar design other than in telemetric systems.

在远动系统中通常仅靠调度端发出的帧同步码兼对执行端晶振分频器整相,以实现位同步的办法。本文为了探索一种既简单又合理的同步方案而回顾了同步方案的几种典型设计思想。最后,归结到以同步码载送帧信息并在信息码中载送位信息的方案。英特尔公司8273型通信控制器就是这种方案的实例。然而这种控制器所采用的 NRZ_I 码,在载送位信息方面是有缺陷的。于是试将 NRZ_I 码改为 Miller 码,这种电码的优越性早为磁录技术所推赞。作者对它的编码与解码逻辑又做了初步设计,果然电路简单,并且消除了英特公司8273的上述缺点。这种同步方案可能不仅对远动设计有利。

Mimomys, as an important guide fossil was mainly found in the Late Cenozoic deposits of Europe. More than 40 local species of the genus have been docmnented in Europe since Forth-Major, created the genus in 1902. Two corresponding genera, Cosomys and Ogmodontomys, have also been identified in North Ameriea. In China, Kormos recognized the first Mimomys, named as Mimomys chinensis sp. nov., in 1934 when he revised the material described originally by Teilhard de Chardin and J. Pivetean (1930) as Arvicolide indet. from Nihewan basin, Hebei. Since then, several species of the genus, M. orientalis Young, 1935, M. banchiaonicus Zheng et al, 1975, M. gansunicus Zheng, 1976, M. heshuinicus Zheng, 1976 and M. youhenicus, Xue, 1981 have been found one af- ter other in the different horizons of the Late Cenozoic deposits of North China. Unfortunately, all the materials collected are so fragmentary and most of the original description of these taxa are so sketchy and scattered in a number of different Chinese publications that the utilization for comparison in detail and for the stratigraphical correlation with other continents, has undoubtly been obstructed. The purpose of the present paper is trying to give a general review of the Chinese Mimys: on reexamination, systematic phylogeny, stratigraphical successions. Some new materials, including a new species——Mimomys peii, collected frown 5 new localities are describad in this paper. Description Mimomys (Villanyia) chinensis Kormos, 1934 Type A right lower jaw with M_(1-3) of young individual (IP 156, Teilhard et Piveteau, 1930, p.123, text-fig. 40; Kormos, 1934, p. 6, text-fig, 1c) (IVPP cat. no. RV 30011). Type locality Xia Sha-gou village, Yangyuan, Hebei. Referred materials A right lower jaw with I and M_(1-3)(V 8109) from Xi Yingzi, Lin Xi, Liaoning; a fragmentary left lower jaw with M_(1-2) (V 4766) and a left M_1 (V 4766. 1) from Jing-gou, Heshui, Gansu (Zheng, 1976, p. 115); a right M~1 (V 6043. 1) and a left M_3 (V 6043. 2) from locs. 77076 and 77078 of Gonghe basin, Qinghai (Zheng et al., 1985, p. 111). Diagnosis Size small. Without cement in the reentrant folds of molars. Prismfold, Mimomys-ridge and enamel-islet lacking. Anterior loop long and anterior cap situated labialy on M_1. Remarks Teilhard de Chardin et J. Piveteau (1930, p. 124) pointed out that the M_1 of Sangkan-ho is identical with that of Mimomys intermedius in having similar design and same degree of hypsodonty, but "rien ne nous autorise encore rattacher l'espce chinoise un genre europen caractris normalement par une brachydonite accentue et la prsence d'un bizarre lot d'mail entre le premir triangle externe et la boucle de la premire dent infrieure." Kormos (1934, p. 5) considered that "L'Arvicolid de Chine tait justement en train de dvelopper ses racines et tant donn cette circonstance, et en considration du dessin des dents, on doit, en premier lieu, le computer au Mimomys." After comparing it with M. neutoni, he cache to the conclusion that "il n'y a ancun doute que l'Arvicolid du Sangkan-ho soit un reprsentant du genre Mimomys, connu jusqu'ici seulement en Europe. Quoique ce type soit trs proche du Mimomys newtoni..." Although Teilh ard and Leroy (1942, pp. 32, 92) still referred it to Arvicola terraerubrae, yet Schaub (1943, p. 286, foot-note 19)regarded it as M. newtoni. Hellet ()957, p. 223) emphasized that Mimomys chinensis "...eine Form vorliegt, die nicht nur aussere Ahnlichkeit mit M. newtoni F. Major hat, sondern offenbar zu dieser sogar recbt nahe Verwandtschaft unterhlt." Both "Mimomys heshuinicus Zheng, 1976" from Jing-gou, Heshui and "Mimomys (Villanyia) laguriformes Erbajeva, 1973" from Transbeigal region, USSR seem to be synonymous with M. (V.) chinensis. Mimomys chincnsis also comforms to the definition of the subgenus Villanyia (Kretzoi, 1956) in lacking cement in the reentrant folds of molars and having an elongated and simplified anteroconid complex on M_1, so, we would like to bake the Chinese species as Mimomys (Villanyia) chinensis. Mimomys orientalis Young, 1935 Type A right M_1 of young individual (be lost) (Young, 1935, p. 33, text-fig. 12). Type locality Dongyan, Pinglu, Shanxi. Referred materials Fragment of a right lower jaw with M_(1-2) (IVPP cat. no. RV 42009) (Teilhard de Chardin, 1942, p. 96, text-fig. 59) from Haiyan, Yushe, Shanxi; fragment of a right lower jaw with M_(1-2) (V 8110) from Jizi-gou, Yushe; a right M, (75 Wei ①1.4, Xue, 1981, p. 37, Pl. II, fig. 6c). Diagnosis A more primitive species of Mimomys, characterized by 1) complete lack or poverty in cement of the molars; 2) the islet-fold, prism-fold and Mimomys-ridge in M_1 persistiug laterally to a lower place and the enamel-islet disappearing late, and 3) Paraneters E, Ea and Eb are 2.33, 2.25 and 1.00-1.25 respectively. Remarks Young (1935, p. 34) wrote that "the closest European form, in shape and in size, seems to be M. savini. From M. savini, M. orientalis difers only by the less opposite position of the third triangle with the third outer folds and the more complicated appearance of the prism-fold of the antcrior lobe." However, Kowalski (1960b, p. 479) pointed out "...this species represents an evolutionary stage similar to that of M. gracilis (Kretzoi) and M. stehlini Kormos." It is quite obvious that some primitive characteristics, for example, relative brachyodont molars, earlier formed roots, later disappeared enamel-islet, more confluent triangles, less or no cement, narrower reentrant folds, shortened and broad anterior loop and lower enamel-free area etc. are not close M. savini, but similar to one of the primitive European species. M. orientalis in size (M_1=2.8-3.12 mm in length) is larger than M. gracilis (2.5-2.6, Csarnota-2 type loc.), smaller than M. polonicus (3.1-3.4) and closer to both M. occitanus (2.70-3.33) and M. stehlini (2.8-3.36). The Parameter E(=2.33) of M. orientalis is inferior than that of M. polonicus (about 2.76-4.07), superior than that of M. occitanus (about 0.7-1.84) and falls within the variation range of that of M. stehlini (about 1.82-4.05). The disappearance of the enamel islet on the M_1 of M. oricntalis is earlier (about at the half of the height of crown) than all the species mentioned above. The noticeable confluence and symmetry of the outer and inner triangles might indicate that both M. orientalis and M. stehlini are in the same evolutionary stage. It is not even impossible that these two species may be synonymous. If so, the immigration of Mimomys between Europe and Asia during the Late Pliocene should be considered. Mimomys youhenicus Xue, 1981 Lectotype A right M_1 of young individual (75 Wei① 1.1, Xue, 1981, p. 37, Pl. II, fig. 6b). Type locality Youhe, Weinan, Shaanxi. Referred material A right M_1 (75 Wei ①1.2, Xue, 1981, p. 37, Pl. II, fig. 6a). Diagnosis A Mimomys slightly more advanced and smaller than M. orientalis, with more developed cement in the reentrant folds and higher enamel-free area on the labiai side of M_1 (Parameter E=3.67, Ea=3.33, Eb=2.17-2.58). Remarks Originally, Xue (1981) referred 4 specimens to her new species, M. youhenicus. During the reexamination, we found that these four isolated teeth might represented three different forms: M. orientalis (75 Wei ① 1.4, vide supra.), Mimomys sp. 2 (75 Wei ① 1.3, vide infra.) and M. youhenicus. The lectctype and another M_1 of M. youhenicus differ from M. orientalis in smaller size, higher crown, slightly smaller enamel-islet, simpler anterior cap and thicker cement. The specimen, an anterior part of M_1 (75 Wei ① 1.3), referred to Mimomys sp. 2 is larger in size and with more primitive characters. Although the Parameter E(=3.67) of M. youhenicus falls still in the variation range of M. stehlini (about 1.82-4.05), it can not be regarded as to be identical with the latter because of its obvious hypsodonty and more abundant cement in the reentrant folds. It is likely that M. youhenicus is at a slightly more advanced evolution stage than booth of M. orientalis and M. stehlini, but primitive than that of M. pliocaenicus and M. polonicus. Perhaps it is nearly at the same stage with M. kretzoii of Hajnk. Mimomys gansunicus Zheng, 1976 Holotype A right M_1 of adult individual (V 4765). Type locality Jing-gou, Heshui, Gansu. Referred materials Fragment of a right upper maxilla with M~(1-2) (V4765. 1) two left M~2 (V 4765.2-3), collected from the same locality as Holotype. Diagnosis Medium sized. In M_1, dentine space between outer and inner salient angles closed, prism-fold wider and extending down to the base of the tooth, islet-fold narrower and ending laterally at a higher level of crown, enamel-islet lacking or disappearing earlier, enamel-free area labially rather higher. Two roots present on M~(1-2). Thick cement in the folds of molars. Remarks The elosed dentine spaces of M_1 between outer and inner salient angles, the absence of the eannel-islet, the thick cement and the rather higher enamel-free area obviously indicate that M. gansunicus is more advanced than M. orientalis, M. youhenicus and M. banchiaonicus of China. Although M. gansunicus is closer in size (M_1=2.92 mm in length) to M. cf. intermedius (M_1=3.14mm) from Lishi of Shanxi (vide infra) or the M. intermedius of Europe, it differs from the latters in having more downward extending islet-fold, Mimomys-ridge and prism-fold, while in European species, "die komplikationen des M_1 (Prismenfalte, Inselfalte, Mimomys-kante, Schmelzinsel) nur zuoberst an der Krone nachzuweisen sind und noch vor Beginn der eigentlichen Wurzelbildung der Abfragung verfatlen. "Konmos, 1931, p. 10) M. gansunicus seems to be closer to "Cromeromys irtyshensis Zazhigin, 1980" (M_1=2.95 mm) both in size and structure, but its narrower prism-fold, robuster Mimomys-ridge and more downwards extending islet fold perhaps suggest that the Siberian form may represent a slightly primitive animal. Mimomys banchiaonicus Zheng et al., 1975 Holotype A left M_1 of an old indivicdual (V 4755). Type locality Lang-gou, Heshui, Gansu. Diagnosis Very large in size; much thick cement on the molars; enamel-islet probably disappearing earlier; prism-fold, Mimomys-ridge and islet-fold persisting down to the base of crown; enamel-free area rather low (Parameter E=0.47); the thickness of enamel on the occlusal surface less differential. Remarks Comparison with the large-sized group of European Mimomys, the M. banchiaonicus is still larger in size. (M_1=4.00 mm) than M. pliocaenicus (M_1=3.41-3.92 mm, after Chaline, 1974), yet close to both M. ostramosensis (M_1=3.10-4.15) and M. rex (M_1=3.8-4.2). Morphologically, it differs from M. pliocaenicus in more downwards extending prism-fold and islet-fold, and the low enamel-free area (Parameter E of M_1 in M. pliocaenicus is about 4.32-5.27, after Chaline, 1974, p. 340, text-fig. 2). M. banchiaonicus differs from M. ostramosensis of Hungary by 1) enamel-islet and Mimamysridge persisting until very late stage of wear, and 2) the enamel-free area obviously much lower than in latter species. According to the characteristics of M. rex given by Kormos (1934): size very large, absence of prism-fold and Mimomys-ridge, islet-fold deeper, with or without enamel-islet, abundant cement and dentine space between outer and inner salient angles closed etc., it should be cosidered that M. rex is more advanced than M. banchiaonicus. Probably M. banchiaonicus represents an ancestor form of the largesized group of Mimomys with thick cement in folds of molars. Mimomys cf. intermedius (Newton, 1881) A fragment of right lower jaw with M_(1-3) (V 8111) from Chaojia-yan, Lishi, Shanxi may be referred to this species, The lower incisor crosses the jaw from lingual to labial side between M_2 and M_3, the muscular impressions sharply defined and the masseter medialis muscle is divided into two parts as in M. intermedius figured by Hinton (1926, p. 369, Pl. XIV, fig. 2). Judging from 1) the length of the lower tooth row (7.17 mm), 2) the disappearing of prism-fold and Mimomys-ridge at a very early stage of wear, and 3) the absence of enamel-islet on M_1, the Chao-jia-yan specimen is identical with that of M. intermedius or M. savini of Europe. The only difference might be that the lingual fold of the anterior loop on M_1 of Shanxi specimen is deeper. Mimomys sp. 1 Materials A right lower jaw with M_(1-3) of a very old individual; a right lower jaw with M_2 and an isolated right M_3 (V 6338). Locality Xicun, Tunliu, Shanxi. Remarks This sample was described originally by Zong et al. in 1982 under the name of M. cf. banchiaonicus. However, its smaller size (M_1=3.68 mm), absence of cement and the persisting of the enamel-islet of M_1 to base of crown are definitely different from M. banchiaonicus and may represent the most primitive species of Mimomys known in China to present. Mimomys sp. 2 Anterior part of a right M_1 (75 Wei ① 1.3) from Youhe, Weinan, Shaanxi described as M. youhenicus by Xue in 1981 is different from either M. youhenicus or M. ori- entalis in its larger size, more downward extending of the islet-fold, thicker and stronger salient angles and more abundant cement of molar, but more similar to that of M. banchiaonicus. Mimomys peii sp. nov. Holotype A right M_1 of an adult individual (V8112). Paratype An anterior part of right M_1 of a juvenile (V 8113). Referred materials 7 left and 5 right M_1 (V 8114. 1-12); 3 left and 3 right M_2 (V 8114. 13-18) ; 2 left and 1 right M_3 (V8114. 19-21); 8 left and 12 right M~1 (V 8114. 22-41); 5 left and 5 right M~2 (V 8114. 42-51); and 2 left and 2 right M~3 (V 8114. 52-55). Derivation nominis Named in honor of late Prof. Pei, W. C, a well-known paleontologist and paleoanthropologist in China. Type locality Dachai, Xiangfeng, Shanxi. Diagnosis Later sized, hypsodont, enamel-islet present only at early stage of wear on M_1, but at very worn stage on M~3; islet-fold, Mimomys-ridge and prism-fold persisting to the base of crown on M~1; dentine spaces of molars partly confluent; thicker cement in reentrant of molars. Remarks M_1 of M. peii (3.20-3.95 mm in length) differs from that of M. banchiaonicus (M_1=4.00mm) in smaller size, higher enamel-free area, less developed cement and lack of enamel band at post-external base of crown. The new species is comparable with European M. pliocaenicus in size, but differs also by higher enamel-free area, earlier disappearance of the enamel-islet, late eruption of molar roots and possessing only 2 roots on M~2 etc. The differences may indicate that M. peii is phylogenetically more advanced than M. pliocaenicus. M. peii is close to M. rex in size, but its later disappearance of prism-fold, isletfold and Mimomys-ridge; labially uncurved anterior cap and more confluent dentine spaces between outer and inner salient angles may indicate that it is more primitive than M, rex. M. peii is close also to M. ostramosensis (M_1=3.10-4.15) in size and in the number of roots of upper molars. From M. ostramosensis, however, the new species differs by the more persistent islet-fold and Mimomys-ridge of M_1, the later disappearance of cnamel islet on M~3 and the more confluent dentine spaces of molars. M. peii is similar to M. reidi in number of roots of upper molars, but distinguishable from the latter in larger size, later disappearance of islet-fold and Mimomys-ridge. As a whole, it may be suggested that M. peii is phylogenetically more advanced than M. pliocaenicus and somewhat primitive than M. ostramosensis, M. reidi and M. rex. Conclusion I. Based on the above descriptions, we set up the Chinese Mimomys zones and their correlation with the European zones tentatively as in the table 5 (see Chinese text). II. Evolutionary trend of Chinese Mimomys 1. The roots of upper molar reduced in number M. orientalis has 3 roots in all of upper cheek teeth; in M. peii sp. nov., the last two upper molars possess 2 roots; while all the upper cheek teeth of M. gansunicus have only 2 roots. Such an evolution trend has been observed in European forms, e.g.M, stehlini, M. ostramosensis and M. newtoni. 2. The deposits of cement There are two different lines concerning the olcarrenee of cement in the reentrant folds cf molars: a) represented by M. orientalis——M. youhenicus M. gansunicus, cement deposits gradually thickened as shown in the European forms of the correlated ages; b) M. banchiaonicus may be near the ancestor of the species filled with thick cement. 3. Height of crown The parameter E of M. orientalis (=2.33) and M. youhenicus (3.67) fall into the range of change of M. stehlini——M. polonicus (about 1.82-4.07), while the M. banchiaonicus (0.47) is roughly the same as the stage of M. occitanus (0.32-1.79). 4. Variation of the anteroconid complex of M_1 a. Anterior cap: The presence of a shorter and broader anterior cap with deeper lingual fold in M. banchiaonicus, M. orientalis, M. youhenicus and M. peii might represent a primitive nature or property. b. Enamel-islet and islet-fold: Morphologically, the evolution trend can be shown as (1) islet-fold beeoming shallow, even lost; (2) enamel-islet disappeared ontologically gradually early; and (3) the shape of enamel-islet changing from oval to circle and the direction of its long axis from anterointernal-postexternal to transverse. The persistance of the islet-fold on the lateral side is almost equal to that of the prism-fold in M. banchiaonicus and M. occitanus; somewhat shorter than the latter in M. orientalis and M. stchlini, and shorter obviously in M. youhenicus, M. kretzoii and M. polonicus. c. The phylogenetic evolution line is characterized by the reduction of both Mimomys-ridge and third labial salient angle projecting outward and by the regression of prism-fold extending to the base of the shaft of M_1. In this case, the M. banchiaonicus, M. orientalis, M. youhenicus and M. peii should be considered as prhnitive forms. III. Chronological sequence of various species of Mimomys in China The following paragraph will discuss shortly on the faunal assemblages associated with the various species of Mimomys found in China. The chronological sequence among the related faunas reflected in accordance with the morphological evolution trend of Chinese Mimomys. M. (V.) chinensis has been found in the fluvio-lacustrine deposits of Nihewan and Gonghe and also in the upper part of Wucheug loess (eqtal to the Zone B of reddish clay of Teilhard and Young, 1931) from several localities in North China (vide supra.) Associated with M. (V.) chinensis are the following taxa: Myospalax arvicolinus, M. tingi, Ochotonoides complicidens, Hypolagus brachypus, Proboscidipoarion sinensis, Equus sanmeniensis, Cervus boulei, Gazella sinensis, Cynailurus pleistocaenicus, Machairodus nihowanensis, Pliohyaena licenti etc.. Such an assemblage, representing Nihewan (s.s) stage, might correspond with the Late Villafranchian of Eutrope (MN 18). M. peii, sp. nov. associaied with Trogontherium minus and a primitive Myospalax (M. omegodon) was found in the gray-green clay of Dachai, Xiang-feng, Shanxi, which may be correlated to the lower part of Wueheng loess (or. Zone A of Reddish clay) in China and might be equivalent to the Middle of Villafranchian (MN 17). The association of M. orientalis and M. yovhenicus in Youhe locality is Chardinomys sp., Kowalskia sp., Hipparion houfengensc etc., which indicate a slightly earlier age and may be equivalent to Early Villafranchian (in part of MN 16). Mimomys sp. l from Xicun, Tunliu, Shanxi probably represents the first appearance of this genus in China. We are not sure at present, however, whether the Xicun fauna, including Hipparion sp., Gazella of. blacki and Stegodon cf. chaii etc., can be roughly compared with Weze-l and Ivanovce (MN 15) or t
