Various kinds of acid igneous rocks are found around the Kushan, to theeast of Foochow, Fukien. One earlier variety of the granites, provisionally termedas Kushan Granite, is coarser-grained, often flesh-colored, and biotite-bearing,similar in character to the most frequently seen and widely distributed graniteof whole Fukien; the other, the Kueichi Granite, often intruding into the firstnamed, is colored by different shades of grey, mostly, fine-grained, and mia-rolitie, containing minor amount of hornblende...

Various kinds of acid igneous rocks are found around the Kushan, to theeast of Foochow, Fukien. One earlier variety of the granites, provisionally termedas Kushan Granite, is coarser-grained, often flesh-colored, and biotite-bearing,similar in character to the most frequently seen and widely distributed graniteof whole Fukien; the other, the Kueichi Granite, often intruding into the firstnamed, is colored by different shades of grey, mostly, fine-grained, and mia-rolitie, containing minor amount of hornblende instead of biotite, yet sometimesvarying its texture to felsitic, porphyritic, or even to micro-graphic. In thecourse of weathering, the soils thus formed from these two granites, as well astheir corresponding surface vegetations are also evidently dissimilar. That the Kueichi granite was really intruding into the Kushan is evidencedby its ramifying apophyses in the latter, its broad marginal phase, its miaro- litie cavities elongated and lined parallel to the intrusive contact and the"sericitization front", so to show a convex curvature facing the Kushan Graniteside along their mutual contact. The prevalent strike of the contact of the granites conicides with thefracture and joint systems of the Kushan Granite, one set of which is N65°E,being also parallel to one of the major vertical joints of the Kueichi. This isprobably due to the prolonged fracturing during the formation of Pacificfolding zones of the Chekiang and Fukien coast, rendering the KueichiGranite intruding along the said fracture system yet itself subjected to the samemechanical stress. Rocks correlated to these two granites are found elsewhere in Fukien. Theymay also be comparable to the two granites of Sihwashan, S. Kiangsi, foundby C. S. Mo and his colleagues. The repeated intrusions of the Post-Jurassicgranites may allow to consider the possibility of repeated formations of theirgenetically related ores. The lead-zinc deposits of Yuntai and Lungyai areprobably related to the igneous activity of the Kueichi Granite.

经初步瞭解,福建鼓山分布着两种后侏罗纪花岗岩。这从岩石地面分布上的接触情况与显微镜下观察的岩石中组成成分的接触情况两方面得到证实的。从二者产生状态看来,彼此生成时间甚为接近,而同属於太平洋运动产物,分属早晚期活动。再根据前人各种地质文件,推论出福建各地普遍存在着相当於这两种侵入的花岗岩类岩石。因此,联系到福建后侏罗纪金属矿成矿作用的多次性可能。这在江西西华山已有发现。此后从多次性来研究后侏罗纪的炎成矿床的成矿作用,成为必要了。

Sustained nociceptive stimuli were applied to the hind limb of 8 monkeys (Macaca mulatta)in three ways:(1)fracturing the fibula;(2)applying a chemical irritant(ether extract of capsicum)to the sciatic nerve topically;(3)injecting hypertonic saline into the gas- trocnemius and its adjacent subcutaneous tissues.All these methods were found to be capable of producing,on the surface of the pinnae,small discrete spots tender to pressure.The topographical distribution of the spots was not regular;but,statistically,they...

Sustained nociceptive stimuli were applied to the hind limb of 8 monkeys (Macaca mulatta)in three ways:(1)fracturing the fibula;(2)applying a chemical irritant(ether extract of capsicum)to the sciatic nerve topically;(3)injecting hypertonic saline into the gas- trocnemius and its adjacent subcutaneous tissues.All these methods were found to be capable of producing,on the surface of the pinnae,small discrete spots tender to pressure.The topographical distribution of the spots was not regular;but,statistically,they often appeared near the tip of the triangular fossa and the antitragus of the pinna.They began to appear from 40 minutes to several hours after the noxious treatment,and persisted for a period from 3 days to a few months(7—10 days on average).Intravenous injection of drugs known to suppress the activity of the reticular forma- tion of the brain stem,such as chlorpromazine or nembutal,augmented the reaction to pressure and increased the number of spots.On the contrary,drugs,such as LSD_(25),amphetamine or adrenaline,which increase the excitability of the reticular formation,suppressed the reaction to pressure and decreased the number of spots.In other experiments,procaine solution was injected into the third ventricle of the brain;1—2 minutes after the injection the referred tender spots disap- peared and reappeared after 13—60 minutes.This fact suggests that the central mechanism con- cerned in the production of the referred tenderness involves neural structure or structures situated in the central portion of the rostral brain stem;and perhaps the mechanism is inhibited by impulses from the reticular formation,as indicated by the experiments of intravenous injection.

用以下三种方法在8只猴人工产生了牵涉性耳郭压痛点:(1)切断腓骨;(2)化学物质(辣椒的乙醚提取物)刺激坐骨神经;(3)下肢肌肉及皮下注射高渗盐水。压痛点可出现于耳郭各处,但比较集中于三角窝尖端及对耳屏附近。压痛点在损伤后40分钟至数小时出现,持续3天至数月(平均7—10天)。静脉注射药理学上认为对脑干网状结构有抑制性影响的药物(氯丙嗪及戊巴比妥)后,压痛点增多,压痛反应增强。注射对网状结构有兴奋性影响的药物(离麦角酸二乙胺、苯异丙胺或肾上腺素),效果相反。这暗示参与耳郭压痛现象的神经结构受来自网状结构的冲动的抑制。第三脑室注射普鲁卡因溶液可在1—2分钟内取消耳郭压痛点,至第13—60分钟又行恢复,表明参与牵涉性耳郭压痛反应的一个中枢环节在脑干前端的中央部分。

Several theoritical problem of the planation surface have been discussed and their significance in scientific research has been demonstrated in this paper.The author acknow ledges that a wearing surface is formed on the land mass during a period of structurally relative stability, under the advantageous climatic conditions(hot or warm and alternating dry and wet), and by denudation and planation, which have planed the geoteotonic surface through a long period. The author had already analized the exogenetic agencies of the formation of this plane, in which the Sule-aeriae denudation and especially, the work of running water are recognized to be the main, and had compared the genetic differences among the benchland of abrasion,“peneplain.”and the piedmont plain of denudation. Age the of the planation surface and the means to date them have been discussed. also It is shown that the problems of whether this plane being of mulliplicity or not depe on a concrete analysis of a concrete region, and thus the conclusion may be made then. The author suggests that the methods of adjacent beds and correlation of pedimentation can be used to determine the age of this plane. Some commone peformations of the planation surface have been classified into four types: that of fracturing, of warpings, of warping-fracturing, and of tilting-fracturing. Every one of these deformational types is interpreted by using some Chinese regions as examples.

本文探讨了夷平面的若干理论问题,并且阐述了研究夷平面的意义。作者认为夷平面的生成是由于陆块在构造相对宁静时期、在有利的气候条件下(炎热的或温暖的并且是干湿更替的),由于剥蚀作用和夷平作用长期削切地质构造面的结果。作者分析了夷平面生成的外力作用,认为主要是大陆剥蚀,尤以其中的流水作用为主导营力。此外还比较了海蚀夷平面、“准平原”、山足剥蚀平原在成因上的差异。文章讨论了夷平面的年龄及其确定方法,认为夷平面是否具有众多性问题只有对具体地区进行具体分析后才能下结论。作者提出可以应用邻接地层法与相关沉积法来确定夷平面的年龄。本文划分最常见的夷平面变形为四类:断裂、拗曲、拗曲与断裂伴生、掀斜与断裂伴生;对于每一种变形类型并且用若干中国区域夷平面资料作为例子加以说明。
