In order to study the stability of non-Newtonian fluid and its flow pattern discrimination method,the integral stability theory and local stability theory are applied to the concentric annulus flowing of plastic fluid and power-law fluid,then a relevant stability parameter expression of discriminating flow pattern is derived and set up in the paper.

针对非牛顿流体的稳定性问题及其流态判别的研究，将整体稳定性理论及局部稳定性理论应用于塑性流体和幂律流体在同心环空的流动中，建立和推导出相对应的判别流动状态的稳定性参数表达式。这些参数的临界值与牛顿液体流态准数雷诺数的临界值，同样具有与液体流变性无关的特点。

The Fresnel lens, also known as the dioptric lens, consists of a central glass disk and concentric glass rings or a central glass band surrounded by parallel glass rings.

一个在中心的玻璃圆片和与之同圆心的层层玻璃圆环，或者中间是一个玻璃带，两边是与之平行的玻璃带状环。

In the first part of the studies, we evaluated the changes of aortic distensibility and its relation with LVH and left ventricular concentric remodeling in patients with primary hypertension.

本研究第一部分通过观察高血压病患者主动脉扩张性的改变及其相关因素，旨在探讨其主动脉扩张性改变与左室肥厚和向心性重构之间的关系。

As one of the main decisive factors of left ventricular after-load, the reduced distensibility of the aortic will increase the wall stress of left ventricle at systole and eventually result in LVH and/or left ventricular concentric remodeling.

主动脉扩张性是左室后负荷的主要决定因素，扩张性减退将导致收缩期左室壁应力增加而引起左室肥厚和/或左室向心性重构。

By means of the K-ε turbulence model and finite element method, the flow of the fluid in the valve and the piston during a cycle of pumping is simulated and calculated. The motion law of the crude oil in the valve passage and concentric annulus in the upstroke and downstroke is analyzed.

针对杆式泵泵简内的流体流动问题，采用湍流模型的K-ε两方程模型和有限元方法，对在一个抽油循环中阀与活塞在几个特定的位置的流体流动进行了建模与计算，具体分析了处于阀道内和同心环状空间中的原油在上下冲程的运动规律。

The experiment used methods of sport biomechanics to investigate the electromyographic magnitude of eccentric and concentric phases under two different stretch amplitudes of drop jumps in order to understand neuromusculor characteristics of different stretch amplitudes of SSC movement.

本研究是利用运动生物力学的方法，探讨肌肉牵张缩短循环（stretch-shortening-cycle SSC）的典型动作drop jump 20、40和60cm之肌肉工作特徵，以便了解浅蹲和深蹲法的DJ跳法之离心和向心收缩二阶段的肌电活动特徵。

According to the requirement of precision diameter measurement of the single crystal silicon sphere, the principle and characteristics of the measuring system were presented, and mathematical models were established for calculating the ellipticity of concentric interference rings with different beam incident angles.

针对标准单晶硅球直径精密测量的需要，本文在介绍标准硅球直径测量系统原理并分析其光路特点的基础上，根据建立的数学模型，对激光束斜入射标准板时产生的椭圆干涉图像进行了分析，并对不同入射角度时干涉环中心点带来的直径测量误差进行了研究。
