Usage of the products such as slight rolled-in metal, roll mark, scratch, herring bone mark, residual oil stain after

板材表面应洁净，不允许有腐蚀、裂纹等缺陷。允许有轻微的金属及非金属压入、辊痕、擦划伤、松树枝状、退火油痕、矫直辊印等不影响使用的缺陷存在。

When the ratio of crack length to borehole diameter is greater, the size effect will be more obvious.

裂纹与井径的比值越大，尺寸效应越明显。

Many typical problems are studied and compared with boundary collocation method, traditional finite element method and analytical methods. The results indicate that the method is accurate and simple for stress intensity factor computation and is easy to be used in practical engineering.

文中作了大量的裂纹应力强度因子计算，与边界配置法、传统有限元法以及解析法进行了系统的比较，结果表明该方法用于应力强度因子计算不但精度较高，而且简便易行，便于工程实际应用。

From the view of fracture mechanics, the problem involving a center crack in a rectangular piezoelectric body under anti-plane mechanical shear displacement and in-plane electrical field is analyzed by the boundary collocation method in this paper.

从断裂力学的观点出发，采用边界配置法研究了含中心裂纹的矩形截面的压电材料在平面内电场和反平面变形作用下的应力场和电场的解，详细介绍了该方法的程序设计过程。

One way is to change boundary condition at the cracked surface during the analysis.

其中一个方法是改变边界条件下的表面裂纹分析期间。

And the examples within the scope of the boundary element method are limited to the simple torsion problems.

对于各向异性柱体扭转问题的研究已有一些，但是对于各向异性材料带裂纹的情况则很少见。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
