On the basis of same reason with part one of this dissertation, we think that true motive force of crack growth comes form the deviator strain energy release.

它们表明了裂纹在金属材料里的扩展过程中，起决定作用的是形状改变比能，而不是整个应变能。

A path independent line integralof the deviator strain energy is proposed by the authors.

在线弹性情况下，推导出了积分与应力强度因子KI的关系。

According to Orowan's investigation results, the amount of plastic work Γ is three orders larger than that of surface energy. However, the yielding of metal material is only associated with the deviator strain energy.

由于引起金属材料屈服的原因仅为偏斜应变能，而与体积应变能无关，本文提出了一个与路径无关的守恒积分，即偏斜应变能积分，并对其守恒性进行了严格的证明。

Moreover, the shear strength was increasing with the increase of the lateral confining pressure. In the unloading process, with the increase of deviator stress and the strain, the soil sample took on a dilatancy trend and showed a large negative pore pressure.

在卸荷过程中，随剪切应力的增大和剪切应变的发展，土样呈现剪胀趋势并在后期产生较大的负孔隙水压力。

As application examples, mode-I stress intensity factors of cracked beams are obtained with present approach, the results are shown to agree well with those of Tada's handbook. The physical illustration of deviator strain energy release rate aboutintegral is given in this paper.

最后建立了利用有限元分析结果来计算积分值的基本公式，改进了当积分路径沿外边界积分时，应力张量难以在边界上分解成应力偏张量和应力球张量的这一缺陷。

In the test, after anisotropic consolidation, keeping the deviator stress, pore water is injected using pore water control apparatus under a constant volumetric strain controlled condition.

该实验是在各项异性的固结作用后保持差应力，使用孔隙水控制装置在体积不变的应变控制条件下将孔隙水注入。

The analysis of the results show as follow:(1)The consolidated-undrained creep, which doesn't include the volume strain, can be expressed by logarithmic functions as a type of under a different deviator stress.(2)The shear creep behaves in a linear elastic character in a lower stress level, and it is a nonlinear behavior in a higher stress level.

分析表明：(1)固结不排水蠕变中没有体积变化，不同偏应力下剪切蠕变可用对数形式表达；(2)固结不排水剪切蠕变在低应力水平下表现为线性粘弹性，而高应力水平时则具非线性的特性。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
