The present paper is the second part of a series of papers on the ncmatodcs of donkeys in Peking. Eight species belonging to the family Trichonematidae are reported, namely, Trichonema labratum, T. labiatum, T. labiatum var. digitatum, T. coronatum, T. longibursatum, T. mimttum, T. tsengi sp. nov., and Petrovinema peculation.Trichonema tsengi sp. nov.A moderately small species. Male 6.4-7.6mm; maximum breadth 0.275-0.345 mm. Female 6.6-8.4mm; maximum breadth 0.275-0.36mm. The anterior extremity tapers slightly to the head; there is no definite neck. Mouth collar moderately high and is marked off from the rest of the body by a constriction. Circumoral papillae projected forward and are as long as the external leaf-crown. The external leaf-crown composed of about 18 long pointed elements, projecting well beyond the mouth collar. The elements of the internal leaf-crown are about 36 short refractive rods. The region of origin of the elements of the internal leaf-crown extends back to 0.005 mm behind the anterior border of the buccal capsule. Buccal capsule is general long and is somewhat narrower anteriorly than posteriorly. It has a depth of 0.037-0.046 mm in the male, 0,038-0.048 mm in the female, with a maximum breadth of 0.032-0.036 mm in the male and 0.033-0.038 mm in the female at its posterior extremity. The walls are thick and swollen at the posterior end and decrease in thickness anteriorly. Dorsal gutter well developed, and projects far into the buccal capsule, extending nearly to the level of the anterior fourth of the buccal capsule. Length of the oesophagus is 0.276-0.348 mm in the male, and is 0.314-0.407 mm in the female. The breadth of the oesophagus is 0.057-0.067 mm at the anterior extremity, and the greatest breadth is 0.081-0.101mm.Excretory pore and cervical papillae are at about the same level behind the nerve ring, and are 0.247-0.379 mm from anterior extremity. Distance from the extremity to the nerve ring is 0.18-0.23 mm.Posterior extremity, male,-fairly long median lobe; lateral lobes marked off from the dorsal lobe by a shallow notch. Main dorsal ray, measured from point of insertion of the externo-dorsal ray is 0.47-0.555 mm in length. Genital cone is well developed, with about 16 processes on its posterior surface.Posterior extremity, female,-straight. Distance of anus from tip of the tail is 0.0875-0.125mm. Distance between anus and vulva is 0.063-0.11mm. Vagina is 0.215-0.39mm in length.Relationship-This worm is more closely allied to T. calkatum than to either of the other species in the calkatum group (of Ihle), but it differs from T. calkatum in the shape of the buccal capsule, in its much greater depth of the buccal capsule in proportion to its width, in the shape of the wall of the buccal capsule, in the number of elements of the external leaf-crown, and in the different shape of the distal ends of >the external leaf-crown elements.Host-Equus asinus. Locality-large colon. Place of distribution-Peking.

本文报告了寄生于北京地区的驴的圆形线虫8种,分属于两个属;内包括一新种的叙述。即Trichonema labratum,T.labiatum,T.labiatum var.digitatum,T.coronatum,T.longibursatum,T.minutum,Trichonema tsengi sp.nov.和Petrovinema poculatum。

The effect of the ratio a/W on the values of δ_i and J_i in a structural steel has been studied by measuring the crack-opening displacement and J-integral at initiation in three-point bend specimens with shallow and deep notches and by finite element method. It is shown that the values of δ_i and J_i for specimens with shallow notches are larger than those of deep notches. The value of the rotational factor γ_p at initiation for different ratios of a/W has also been studicd, and it is...

The effect of the ratio a/W on the values of δ_i and J_i in a structural steel has been studied by measuring the crack-opening displacement and J-integral at initiation in three-point bend specimens with shallow and deep notches and by finite element method. It is shown that the values of δ_i and J_i for specimens with shallow notches are larger than those of deep notches. The value of the rotational factor γ_p at initiation for different ratios of a/W has also been studicd, and it is sbown that γ_p is decreasing with decreasing of a/W.

用三点弯曲试件对a/W值不同的常用结构钢在开裂时的裂纹张开位移(COD)δ_i和J积分值J_i进行了试验研究。试验结果表明,a/W值减小,则材料的δ_i值和J_i值增大。当a/W=0.1时·其占δ_i值与J_i值为a/W=0.5时的二倍。试验结果得到了有限元计算结果的证实。利用引伸计和硅橡胶对不同a/W值时的转动因子r_p值进行了试验研究,试验结果表明,r_p值随a/W值的减小而减小,当a/W=0.5时,r_p=0.45;而当a/W=0.1时,r_p=0.16。

Up to now, there still exists the divergence of the view on species and subspecies of the subgenus Eospalax. Our classification is as follows:1. M. r. hubeinensis, subsp. nov..Diagnosis: The new subspecies is distinguished from M. r. rolhschildi by its tail being longer than 38 mm and skull being larger than 40 mm in adults. Moreover, the ridge of upper orbit and temporal ridge are quite evident and approach each other in the midline. Posterior surface of the nasal has a shallow notch. The widespreading...

Up to now, there still exists the divergence of the view on species and subspecies of the subgenus Eospalax. Our classification is as follows:1. M. r. hubeinensis, subsp. nov..Diagnosis: The new subspecies is distinguished from M. r. rolhschildi by its tail being longer than 38 mm and skull being larger than 40 mm in adults. Moreover, the ridge of upper orbit and temporal ridge are quite evident and approach each other in the midline. Posterior surface of the nasal has a shallow notch. The widespreading zygomatic arches are also the chief distinguishing feature of the skull.Distribution: Eastern region of Daba mounutin, Shaanxl Province and Badueng and Shen-uengjia region, Hubei Province.2. "M. cansus" and "M. baileyi" should be resumed as subspecies of M. fontanieri.We have observed 160 specimens of "M. cansus" and "M. baileyi" which are revised by Fan & Shi 1982, and discovered that there some intermediate types between "M. cansus" and "M. fontanieri", between "M. baileyi" and "M. cansus". There are resemblances in the chromosomes and LDH isozyme. It is no doubt that "M. cansus" and "M. baileyi" should be regarded as subspecies of M. fontanieri, i. e., M. f. cansus and M. f. baileyi.3. "M. rufscens" and "M. c. rufescens" should be revised as M. f. rufescens.The differences between "M. c. rufescens" and M. f, cansus accord with the 75% rule of the variation in the subspecies. Therefore, "M. rufescens" and "M. c. rufescens" should be revised as M. f. rufescens.4. M. smithi should be resumed.The main difference between "M. rufescens" and M. smithi is that the upper orbit and temporal ridge of the former approach each other in the midline but never merge, however that of the latter merge together. The diagnostic characters between M. smithi and M. f. rufescens are quite evident, and there are not any intermediate type, so that M. smithi should be resumed.

本文通过形态特征的比较分析,结合染色体组型和血清LDH同工酶电泳的研究结果。对鼢鼠属凸颅亚属种和亚种分类进行了研究,认为此亚属为3个种、共7个亚种,并且记述了一新亚种——罗氏鼢鼠湖北亚种。
