简介：压力紧张曲线一-Ti-8Mn合金被测量然后它与有限元素方法是计算的(女性)基于单身者和阶段合金的压力紧张曲线。由把计算压力紧张曲线与测量那条作比较，他们适合对方很好，这能被看见。因此，在这个工作造的FE模型是有效的。根据上述提及的模型的意见，在and阶段的应力和紧张的分布被模仿。压力坡度在两个和阶段存在的结果表演，和应力的分布是不同类的。在阶段内的压力在接口附近通常比那高。同时，在阶段的压力在阶段是比那低的，而在阶段的紧张在阶段比那高。

简介：为紧张坡度的一个无限的平板，敏感材料使遭到了到飞机紧张张力的装载，建立的计算和分析证实在装载的一些舞台的侧面的边界的那钝化在进一步的装载之上禁止塑料变丑。除了显著地，如果坡度术语贡献驱散，塑料变丑完全被关上并且仅仅在清楚地定义的更高的负担恢复之外，这结果在自己是不令人吃惊的，相应于全部的紧张\(\varepsilon_c\)，说。在这份报纸介绍的分析证实塑料变丑追随者钝化的延期并且决定塑料流动在恢复的准确方式。塑料紧张率在塑料流动的恢复的准确的点\(\varepsilon_c\)是连续的并且为在强加的全部的紧张的第一小增长\(\Delta\varepsilon=\varepsilon-\varepsilon_c\)，在塑料的相应增长紧张，\(\Delta\varepsilon^\mathrm{p}\)，与\成正比((\Delta\varepsilon)^2\)。在关系\的经常的A(\Delta\varepsilon^\mathrm{p}(0)=A(\Delta\varepsilon)^2\)，在此\(\Delta\varepsilon^\mathrm{p}(0)\)在平板的中心表示塑料紧张增长，明确地被决定了；它取决于材料的变硬的模量。除非消散的术语是不在的，精力充沛的坡度术语的存在没在\(\varepsilon_c\)的价值上有效果，在哪个情况钝化减少塑料变丑的率，但是不介绍延期。消散的坡度术语的这质的效果打开他们的存在或缺席的试验性的辨别的可能性。分析采用是可能的处于另外的问题发现使用的增长变化明确的表达。

简介：克服做特别在宽乐队差距半导体，在半导体的瓶颈是在半导体物理的挑战许多年了。在这份报纸，我们在提高由表面活化剂和紧张做考察一些最近的进步。我们证明那表面活化剂和紧张是二条有效途径在取向附生的生长提高掺杂物溶解度。表面活化剂能在乐队差距内深介绍精力水平，使主人混合物不太稳定，因此降低故意的掺杂物的形成精力。紧张提高了做基于掺杂物导致的观察在主人的体积变化。如果当掺杂物导致了体积变化，外部紧张在一样的方向，掺杂物的形成精力被减少。这效果能被用来调节做地点，因此做类型，在一位主人。两个都包括紧张和表面活化剂的一个混合方法被建议，它能是一个有希望的一般方法进一步提高做。
