| 8. | With the disposal of the image , we get a changing rule that the change of the sample of pmma ' s surface crazing damage density follow the change of time and stress 经图像处理,得到了在不同应力水平下、不同基温下, pmma试件纹损伤面密度随时间的变化规律。具体地, 1 |
| 9. | And pbo single crystal nanowire was successfully prepared with new method . the results show that the amorphous matrix of the powders almost completely transforms into crystalline perovskite phase after 600 calcinations . the mean grain size in pt / tb powder is about 23nm that is smaller than that of pt powders 钙钛矿相的晶轴比c / a比未掺tb的pt粉末低,具有赝立方结构的特性,降低了从立方相向这种四方相转化的势垒,从而有效地抑制了较高温下焦绿石相的产生。 |
| 10. | In this paper , we take high molecule physics and the damage theory of rheologic material with lacuna as the basic , make the experiment as a mostly measure , take the pmma as a research object , to study the pmma ' s nonlinear viscoelasticity of high polymer . the technique showing minute details in minute view measure is used by the author to observe the change of crazing damage density follow the change of stress , time and temperature in term of creep and flab 本文以高分子物理学、含缺陷流变性物体的材料破坏理论为基础,以实验为手段,以工程中常用的pmma为研究对象,对pmma银纹破坏的非线性力学行为进行了研究。作者采用显微技术,对pmma在蠕变或松弛条件下,不同应力水平和不同基温下的pmma银纹损伤进行了实验研究。 |
