With the adoption of the rate-sensitive constitutive relationship, it is asymptotically investigated the propagating tip fields of antiplane mode III crack under the condition of incompressibility, and the dynamics equations are obtained separately governing the stress and strain fields at the crack-tip.

采用这种率敏感型本构关系，本文对不可压缩条件下反平面Ⅲ型扩展裂纹的尖端场进行了渐近分析，分别求得了其裂纹尖端应力和应变场的动力学控制方程。

采用这种率敏感型本构关系，本文对不可压缩条件下平面应变Ⅰ型、Ⅱ型和反平面Ⅲ型扩展裂纹的尖端场进行了渐近分析，分别求得了其裂纹尖端应力和应变场的动力学控制方程。

However,after addition a little apolar molecules,apolar molecules insert into hydrophobic microdomains,which makes PPO chains extend at certain degree,and the order of LLC increases.Therefore,the systems will supply favorable conditions for enhancing the solubility of oil-soluble molecules,which further expands application prospects of the systems.

而加入少量极性较小的油溶性分子后，油溶性分子填充到PPO链段间，使得PPO链段在一定程度上得到伸展，液晶层间距增大，两亲分子排列的有序性增强，这就为油溶性分子的增溶提供了有利条件，扩展了该体系的应用前景。

In this lesson we want to expand on that direction by adding appendages to these basic forms.

在这一课中，我们希望在这个方向扩展，加入附加的这些基本形式。

Packets transmitted by AARP that determine if a randomly selected node ID is being used by another node in a nonextended AppleTalk network.

AARP（AppleTalk地址解析协议）发送的数据包，用来确定在一个未扩展的AppleTalk网络中，一个随机选择节点ID是否被另一个节点使用。

With these technologies,application developer can develop and deploy a reliable,extensible,secure enterprise application rapidly.

The resistance of strawberry was observed at each phase of the invasion after formation of the appressorium.

而草莓不同品种对白粉菌的抗性表现在附着胞产生后的各侵染阶段，随品种抗病性增强，病菌侵入率降低，吸器数目减少，菌丝扩展缓慢，分生孢子数目减少。

In this dissertation we extend the application of pair approximation and moment method and build the particular model in background of sex ecology.

综上，本文一方面扩展了偶对近似和矩方法的应用范围，建立了不同背景下的具体模型。

This new method not only reduces the compute, but also needs not apriority information of the targets compared with Wishart classifier.

该迭代方法与基于Wishart距离的迭代分类方法相比，不需要矩阵的求逆运算和矩阵的对数运算，降低了迭代过程的计算量，也不再需要目标的先验信息，扩展了其适用范围。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。
