屈服形变 meaning in English

deformation at yield

The distribution of modified and unmodified nano - particles in pp were studied by means of tem , it showed that modified nano - particles dispersed much better than the unmodified nano - particles . the improved contribution of nano - particles lead to more ( 3 - pp formed and microscopic damage , all those structural changes caused the improvement of the mechanical properties
通过tem分析发现经过表面改性后的纳米粒子比未改性的纳米粒子在pp中具有更好的分散性，分散性的改善更有利于诱导- pp的生成以及诱导基体发生剪切屈服形变，正是这种结构上的变化导致了力学性能的改善。
The mechanical properties of the modified nano ~ cac03 / pp is better than that of unmodified nano - cac03 / pp , especially the impact strength has been improved greatly . but when the dosage of nano - particles is too much , those nano particles will accumulate and this will lead to decreasing of strength of the material . through investigated of xrd and dsc , we found that ? - pp was formed by addition of nano - particles
通过xrd和dsc分析发现，纳米粉体对- pp有诱导生成作用：通过sem分析发现表面改性后的纳米粒子填充即后，与pp基体结合较好，基体在冲击方向存在层状滑移，并有纤维状形变，显示基体发生了剪切屈服形变。
