In common glass fiber reinforced polyolefine pipe, when the volume faraction is less than the critical value, the glass fiber can not act as reinforcement, on the contray, it would reduce the whole intensity of the compound material. However, when extruded in combined stress field, the extend intensity of the compound system increases when the volume fraction of glass fibers is less than the critical value. When the glass fiber volume fraction is higher than the critical value, the required glass fiber volume fraction of compound fibers extruded in the combined stress field is less than theory value.

一般玻璃纤维增强管材在常规挤出时当添加的玻璃纤维体积含量小于临界体积分数(当添加的玻纤的复合体系拉伸强度等于基体聚合物材料的拉伸强度时的玻纤体积分数)时，玻纤起不到增强的作用，反而会使复合材料的整体强度降低；但在复合应力场下挤出时，当添加的玻纤含量小于临界体积分数时，复合体系的拉伸强度不但没有降低反而升高了；当添加的玻纤含量大于临界体积分数时，复合体系要达到同样强度，经过复合应力场的玻纤增强管材需要的体积分数小于理论值。

This article starts with the modificatory production function, establishes a new frame for theory analysis, based which this article then analyses the action mechanism of extrusion effects MNCs gives to China, and discusses the three different phases of MNCs'employment effects, namely absorb effects in short term, extrusion effects in medium term and draught affects in long term. Bases on the analysis, the article makes a new explanation of China's employment elasticity since China's reform and opening.

本文从修正的生产函数入手，构建了新的理论分析框架，在此基础上分析了跨国公司对国内就业的挤出效应的作用机制，论述了其就业效应的三个不同阶段，即短期的吸收效应、中期的挤出效应和长期的拉动效应，并在此基础上对改革开放以来中国就业弹性的变化做出了新的解释。

The results indicate that the interface curve in width varies along the flow direction. The flow rate ratio controls the coextrusion interface location. The interface deviate value increases with the increasing of the flow rate ratio. The difference viscosity of two layers polymer leads to the interface deflecting towards the lower viscosity side.

结果表明：宽度方向共挤出界面的形状和位置沿聚合物流动的方向不断变化；界面偏移量的大小随着流量差异的增加而增大；聚合物入口流量的变化是导致共挤出界面位置变化的决定性因素，流量比的变化对出口处界面形状的影响不大；两种聚合物粘度的不同会导致界面偏向粘度较低的熔体一侧。

Relying on both dynamic and static analysis methods,both microstructure and macrostructure analysis methods,both on-line and off-line analysis methods,as well as both along-line sampling and die sampling techniques,the author of this thesis studied and developed an on-line microscopic system,the on-line rheometers and the on-line samplers which are used in single screw extruding process for the first time. Based on the analyses of a plenty of experimental results, the thesis mainly discussed following several questions: solid-bed break-up phenomenon on macroscopic scale,melting and deforming mechanism of a solid particle on small particle scale,and polymer morphology on microscopic scale.
