From the result we know the reason of increase local bearing strength, appearance of crack, position of c rack, r eason o f c rack d eveloping.

且对在局压时的压应力的扩散情况进行了探讨，对扩散路径的扩散距离进行了分析。

In general, the directions of principal compression strain rate are congruent with horizontal projection of principal compress axis derived from medium and large earthquakes.

The direction of the principal compressive strain obtained in the paper is well consistent with the principal compressive stress axes derived by the geological and seismological methods.

用本文方法得到的主压应变方向与地质学方法和测震学方法得到的主压应力轴方向具有很好的一致性。

Based on plate-beam structure and layer-plate model, the time delay on sloughing rockburst in mines is studied.

研究表明，在压应力集中区内，近自由表面的裂纹在低侧压时，将平行于壁面沿最大压力方向扩展，在一定的压力下，受自由表面的影响，这种扩展是不稳定的。

It also demonstrated that degradation slope of Vth will become lower and reach a constant quantity. Higher Temperature and gate voltage enhanced the V〓, shift of PMOSFET. With the gate oxide growing thinner and channel length growing more lessen, the influence of NBTI effects will become more and more severity.

应力温度的升高以及负栅压应力的增大都会使器件的V〓漂移增强，而且随着器件栅长L的减小，栅氧厚度T〓减薄等使PMOSFET中的NBTI效应呈现出了增强的趋势，这使得NBTI退化有可能成为未来CMOS器件发展的严重障碍。

Through contrast analysis of stress value,the paper found warren box girder can improve prestress and precompression of prestress concrete box girder under border and box girder bearing capacity,reduce the distribution of prestress wire,saving construction quantity.

通过对同等条件的直腹箱梁和斜腹箱梁的应力值对比分析，提出将直腹箱梁改为斜腹箱梁后，可以提高预应力混凝土箱梁下缘的预压应力，提高箱梁承载力，降低预应力钢绞线的配置，节省工程数量。

In this test a simply supported plain concrete beam is loaded at its third points, the resulting bending moments inducing compressive and tensile stresses in the top and bottom of the beam respectively.

在本试验中一简支素混凝土梁在其每个三分之一处受荷，弯曲瞬间在梁的顶部和底部分别产生压应力和拉应力。

In this paper,the surface roughness and residual stress of 1Cr11Ni2W2MoV stainless steel after laser shock peening and shot peening were tested and analyzed.The results show that laser shock peening samples have better surface quality and larger residual stress than shot peening samples.

对不锈钢材料1Cr11Ni2W2MoV进行了激光冲击强化和喷丸强化后表面粗糙度和残余应力测试分析，与喷丸相比，激光冲击强化对试件表面形貌和表面粗糙度的影响更小，产生的残余压应力更大。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
