First , the researchers tested whether their system could locate the small pulsing movement caused by a vibrating ball 首先,研究者们测试人工侧线系统能否定位由一个振动球产生的微小脉冲水波。
A natural lateral - line system consists of about 100 sense cells that run from the gills to the tail on each side of the fish 鱼身上天生的侧线由大约100个经鳃延伸至尾部的感觉细胞串联构成,两侧各一。
This time , the artificial lateral - line system could work out the general direction of the source and identify the pattern of the vortices 这次人工侧线系统能够得出漩涡源头的大致方向,也能识别出漩涡的图形。
Having proved his point , dr liu is now trying to design sensors that work more like the sense cells in a real lateral line 在自己的想法得到验证后,刘博士目前正在试图设计一种工作方式更接近鱼类天然侧线系统中感觉细胞的传感器。
2 . the rigorous thermodynamic model has been applied to study the characteristics of cryogenic distillation column having feedback stream with hydrogen isotope system in steady state 2 、应用严格的热力学模型研究了带有侧线循环及平衡反应装置的氢同位素低温精馏塔的稳态分离特性。
Abstract : the paper analyzed the properties of concentric curve , theprinciple and method of setting out stakes of middle - line & sidings on one random station and closed with main points 文摘:分析了同心曲线的性质,提出了可在任意点设站测设同心曲线的原理及放样同心曲线的中线、侧线各桩并闭合于各自主点的方法
Operation : the performer puts his palm to stroke with strength from “ tian tu ” down to “ jiu wei ” along with “ ren mai jing ” , then strokes separatedly to both sides line and then returns lightly to the beginning repeatedly for six to thirty six times 操作:术者两手伸开以全掌着力,以受术者的“天突”部位开始,沿任脉经向下抚至“鸠尾”处,然后向左右分抹至体侧线,轻抹带回至起点,反复操作六至三十六次。
Diagnostic characters for the recognition of species include the presence or absence of pectoral fin , the position of dorsal fin origin , gill opening , anus , nostril opening and eye , the cirri present or not , the dentition type , the body coloration , and the head pores or lateral line etc 一般依据胸鳍的有无或发达程度,背鳍起点、鳃孔、肛门、鼻孔和眼等的相对位置,颌的发达程度和颌上是否具须,齿的形状和排列方式,身体的斑纹,以及头部和体侧的侧线孔数目等进行鉴别。
