The second section describes the morphological features and the swimming mechanisms of fish and explains the reason why this paper chooses bcf propulsive fishes as the model 在第二部分里描述了鱼类游动机理和行为特征，并对本文为何选择bcf推进式鱼类作为仿生对象作了解释，并说明了尾鳍运动学参数和受力情况。
Such a style will minimise the chance of losing the ball in build up play and will allow the team to constantly pepper the opposition area , hopefully forcing the defence into making mistakes 这样的打法会减少丢球的可能性，特别是在推进式的打法，而且也可以让球队持续在对方的区域内撒野，尽可能地使得对方防守犯错。
Especially for the focus of small intestine hemorrhagic disease , push - endoscope is difficult to reach , and even though the push - endoscope could be capable to reach , on the insert process push - endoscope may bring terribly pain 对小肠出血性疾病的病灶,推进式内窥镜难以到达,即便能够到达,在插入过程中也会引起极大的痛苦。
But for most developing countries , it is the government who initiates the security market , which makes detailed and appropriate theories of security market regulation a necessity to act as theoretical guide for the government 但对大多数发展中国家而言，证券市场的建立大多是国家推进式的，这就要求有全面准确的证券市场监管理论作为国家推进的参考。
The main contents , general structure scheme of this dissertation are given . in chapter 2 , the principles of erp and jit are presented . the push system of erp and the pull system of jit in logistics control field are analyzed 第二章：阐述了erp 、 jit的运作原理，分析了erp中“推进式” 、 jit “拉动式”的物流控制模式及其特性，并系统归纳了toc中的物流控制原理。
The robotic fish model selected in this paper which consider an idealized bcf propulsive fish model that consists of only three links : the rigid body in the foreside ; the high aspect ratio caudal fin ; the caudal peduncle which connects the caudal fin and the body 机器鱼的模型建立是把理想的bcf推进式鱼类分为三个部分，分别是：前部刚性的身体，大展弦比的尾鳍和一个连接以上两部分的尾颈。
Because of the difference of production technology and operation condition , the jacket heating type divides electric bar heating , steam heating , conduction oil cyclic heating , and the shaft seal equipment divides stuffing seal and mechanical seal , and mixing type divides anchor type , paddle type , worm wheel type , pusher type and frame type 由于用户因生产工艺操作条件不尽相同，夹套加热型式分为电热棒加热蒸汽加热导热油循环加热，轴封装置分为填料密封和机械密封，搅拌型式有锚式浆式蜗轮式推进式和框式。
The purpose of this research is to study the meaning and characteristic of nimble manufacturing system to the firework enterprises " product , and study the two systems of integration push type and pull type based with the theory of constraint , and also build a planning and controlling system meeting the characteristic of the nimble manufacturing system and the requests of fireworks products 本研究初步的目的在于探讨敏捷制造系统对于烟花企业生产的意义与特性,接着期望通过以约束理论为基础的研究,对整合推进式与牵引式两系统加以研讨,探讨如何通过对先进生产系统的整合来建构出既符合敏捷制造系统特性又符合烟花生产要求的计划和控制系统。
