I don't know where Greg got his idea of applying the concept to a crack anchoring device. Perhaps it was from the Jumar ascender, which uses a more-or-less constant angle cam to clinch the rope. At any rate we have Greg to thank for introducing the concept to crack anchoring technology.

我不知道Greg从何获得此一主意用於裂隙确保，或许是从犹玛攀升器，因其使用类似的等角凸轮钳住绳子，无论如何我们都要感谢Greg将此概念引进到裂隙确保技术上。

One is the effect of LT crack of wood on wood transverse bending property. Birch, ash tree, walnut are studied, and it appears that under the bending loads the bending strength of the beam with crack will decrease, but not obviously .

第一部分研究了木材LT型裂纹对木材横纹理弯曲性能的影响，在对桦木、水曲柳、核桃楸的研究中，发现含LT型裂纹的横梁在弯曲载荷的作用下，其弯曲性能会有一定程度的下降，但降幅并不明显。

Assuming that the elastic modulus was the exponential function of special coordinates and the Possion＇ s ratio was constant, the higher order asymptotic stress fields near the crack tip for the mode Ⅰ crack in the FGM were considered.

假设弹性模量是空间坐标的指数函数，泊松比恒定，对于功能梯度材料中的Ⅰ型裂纹，裂纹尖端应力的高阶渐近场被研究。

Take/have a crack to make an attempt to do something 尝试 I've never done this before, but I will have a crack at it.

我以前从未做过这个，不过我将试试看。

The welding juncture of the axis head and the surrounded plate in the holding circle of bessemer converter crack severely .By means of analysis to the material,the structure and the process,we find out that one of the main reason of crack is the thickness of welding plates vary a lot, the other is that it isn't penetrable for welding.

转炉用托圈的轴头与围板焊接处严重开裂，通过对其材质、结构、工艺进行分析，找出接头断裂的主要原因，一方面是由于焊缝连接件厚度相差悬殊，另一方面是由于焊缝未焊透，这两方面原因造成应力集中。

Roast Style 5 → Full City+ Roast means the coffee is roasted to the stage counted from 30 seconds after 2nd crack to 60 seconds after 2nd crack. End of North Italian Roast. At this stage you can hardly feel the acidity and dancing aromas; instead, you get more bittersweetness and pungency notes and more body in the cup. Dry-Processed Mochas and Sumatra/Sulawesi coffees are roasted to this stage in most cases.

Roast Style 6 →维也纳式烘焙 Vienna Roast，中义式烘焙的起点，第二爆60秒~90秒剧烈期的程度，烟熏类的香气结构，几乎已很难察觉到酸味的存在，苦味比例较高，因此带有黑巧克力苦甜味的豆种在此时会更像高纯度黑巧克力的风貌，另外像摩卡类的咖啡豆此时也会有迷人的酒香微熏感。

The branch crack problems in a finite-width strip were solved by using the complex potential of a branch crack of half-plane, in which the distributed dislocations were assumed along all the branches arid one boundary of the strip.

假设沿分叉裂纹各分支和板条边界有某位错分布，利用半平面内分叉裂纹问题的复势函数，将板条分叉裂纹问题转化为半平面内的多分叉裂纹问题处理。

The germination, expansion and reciprocity of the crack inside the material embody on the crystal bound of the material. So, in this study we can change the bourgeon and extend condition of the tiny crack inside the material by design and control the crystal interface structure effectively and provide new research approach for the design and manufacture of the machinability ceramic.

由于材料的破坏和加工都决定于材料内部微裂纹生成的难易程度和扩展程度，而材料内部裂纹的萌发、扩展和相互作用集中表现在材料的晶界和相界面上；因此，本研究通过有效的设计和控制界面结构，改变材料内部微裂纹的萌生和扩展条件，为可加工陶瓷的设计和制备提供新的研究途径。

With the methods of conformal mapping and the Cauchy integral, two cases of crack geometries are studied: one is for a crack emanating from a circular hole and the other is for two symmetric cracks emanating from a circular hole.

利用保角变换和 Cauchy 积分的方法，对含有圆孔孔边单裂纹和双裂纹的压电弹性体分别进行了分析。

The witness also told the jury at the Royal Courts of Justice in London that he saw a paparazzo fighting with a member of the public who was trying to stop him taking pictures in the minutes before the emergency services arrived.

他还告诉在伦敦皇家法庭的陪审团，在急救服务到来之前，他当时看见一个狗仔队正和一群阻止他拍照的人打架。
