组成缺陷

它能在不损坏被测工件材质以及结构条件下，以断层图像的形式，展现被检测物体内部结构关系、物质组成以及缺陷状况。

It can show the internal structure , composition and defect of the detected objects in the form of slice images while the structure and material of the workpiece is not damaged .

本篇论文首先介绍了TCP／IP网络的基本组成原理及其缺陷，同时介绍了防火墙的主要技术类型，并详细描述了包过滤型防火墙的工作原理。

The author firstly introduces the fundamental principle and some shortcomings of the TCP / IP network in this thesis , simultaneously presents the main technical types of the firewall , detailedly describes the principle of the packet filter .

进一步对交替介质层由空气和金红石（TiO2）组成而非线性缺陷层由聚合物（polydiacetykene9-BCMU）组成的光子晶体模型的透射特性进行了数值分析。

Further more , the transmittances of two opposite directions for a realistic photonic crystal model which alternating layers are consisted of air and rutile ( TiO2 ) and a polymer ( polydiacetykene 9-BCMU ) as its nonlinear defect layer were numerically analyzed .

这个框架由以下几部分组成：决定缺陷浓度的非线性微分方程，静电势函数和内应力。

The framework consists of a system of nonlinear differential and algebraic equations governing the defect concentrations , electrostatic potential and the mechanical stresses .

对于复合材料，界面往往是重要的组成部分，也是缺陷极易发生甚至断裂破坏的地方，从而影响材料整体的力学行为。

Interface is usually one of important parts in composite materials , but default or broken is often happened in this place , so that the whole mechanical behavior of composite materials is suffering to destroy .
