双峰驼股神经的解剖

利用大体解剖学的方法对一个成年母驼后躯及３个股中部以下的标本（左二右一）进行了观察研究。结果表明：股神经由第五至第七腰神经的腹侧支构成。股神经由腰荐神经干的前部发出后,在髂腰肌里延伸,有髂腰肌神经发出,并有肌支分布于髋关节肌、股四头肌,主干延续为隐神经。隐神经主要分支分布于股膝内侧、小腿和跗关节内侧面的皮肤和筋膜。

Anatomy of the Thoracic Splanchnic Nerves in Pigs

The anatomical features of the autonomous nerves, including the greater, lesser and least splanchnic nerves, were examined in 4 female and 4 male adult pigs (Sus scrofa). The origin and course of these nerves were examined with regard to sex and the side of the body. The greater splanchnic nerve was present in all of the animals included in the study, whereas the lesser splanchnic nerve was present at a rate of 87.5% on the right side and 75% on the left side of the median plane. On the other hand, the least splanchnic nerve was present on the right side at a rate of 62.5% and on the left side at a rate of 37.5%. The greater, lesser and least splanchnic nerves on the right side of the median plane were determined to originate from a more cranial location. Furthermore, these nerves were observed to be longer and larger on the right side in comparison with the left side. Evaluation of the findings revealed no significant difference between both sides of the median plane with regard to the origin, course and dimensions of these nerves. Similarly, no significant difference was detected between sexes.     

黄河口尾闾段河道出汊机理中的河床边界条件

黄河口尾闾段河道出汊机理研究涉及出汊类型、出汊特征、水沙与河床边界条件等问题,河床边界条件是河道出汊的关键影响因素之一。研究在探明近期黄河口尾闾段河道出汊摆动特点的基础上,揭示了黄河口尾闾段河道出汊机理,并基于黄河口尾闾段实测地形资料,探析了河床边界条件的时空变化特征及其对河道出汊的影响。结果表明：河相系数是决定黄河口尾闾段河道出汊位置的主要影响因素,滩地横比降变化特征和深泓线位置变化决定河道出汊的摆动方向。
