针对钻井过程中钻遇的盐层段井眼蠕变缩径问题，利用弹塑性力学理论，蠕变本构方程采用Heard蠕变方程，在平面应变和均匀地应力假设下，推导出控制井眼收缩的钻井液密度新公式，该公式与前人推导的公式不同。

The value of mixity angles becomes smaller with increasing strain hardening exponent at the same load level .

在同一外加载荷下，接头复合角Φ随着焊缝应变硬化指数的增加而减小。

The strain in the siloxane linkage, which can vary from one linkage to another, would depend mainly on the temperature at which the zeolite is held.

这种硅氧烷鍵的张力的大小(对不同的键可以各不相同)主要取决于沸石所处的温度。

Strain rate hardening due to GBS suppressed the DRX softening and local necking so that the uniform and total elongations tended to increase at the temperatures of 400℃ and 500℃.

而晶界滑移所导致的应变速率硬化效果，则会降低动态再结晶对於材料的软化作用，进而增加AZ31B镁合金在400~500℃的均匀延伸率，并因抑制颈缩现象的进一步发生，而增加高温延性。

Results showed that at a given position on the storage vessel surface, the hoop strain was increased with a higher packing fraction of alloy powders during the cyclic hydriding/dehydriding reactions. This resulted from a larger amount of pulverized fine powders generated by a larger packing fraction of alloy powders.

结果显示，在储氢罐表面之特定位置上，其切线方向应变随著粉末填充率提高而增加，这是由於较高的粉末填充率产生较多的粉碎细小粉末所导致。

Analyzing the dynamic behavior of dislocations in the deformed metal at high temperature and high strain rate, a new theoretical model of dislocation dynamic behavior is put forward to describe the dynamic recrystallisation mechanism of the weld metal.

The low speed institute of CARIA has developed the new technology through which the low speed wind tunnel force measurement test for civil airplanes are carried out. In order to reach the international standard, we have sequentially designated the special strain ganged balance, and improved the model support and the steady wind speed's controlled system.
