1) shear dislocation
剪切位错
2) shear dislocation
剪切错位

4) stagger cutting
交错剪切
5) shear moving
剪切错动
1.

尽管人们已经认识到清水压裂的效果主要来源于裂缝面的粗糙性和相对剪切错动,但对于清水压裂裂缝的闭合形态等理论问题研究得不多,也缺乏有效的理论指导现场施工。
6) shear displacement
剪切位移

对充填砂裂隙进行控制位移的剪切渗流实验,结合充填砂的物性,揭示了岩体裂隙发生剪切位移时的渗流规律,并对剪切位移与隙宽、剪切位移与流量、隙宽与流量的关系进行了探讨,提出了砂粒的微小扰动与孔隙比(隙宽)的增加是影响裂隙流量的主要因素。

In this paper, a new method is proposed to establish nonlinear relationship between normal aperture and shear displacement in joint shear tests, which is described by a BP neural network NN( n,h 1,h 2,1).
通过建立一个多层神经网络模型NN(n,h1,h2,1),探讨了描述节理开度与剪切位移之间的非线性关系和尺度效应的新方法,由小尺度试件节理的实测数据建立的非线性模型可以推广地预测出较大一些尺度试件的节理开度值。

不全位错
partial dislocation
不全位错partial disloeation伯格斯矢量不是晶格恒同平移矢量的位错。它是堆垛层错的边界,也即是层错与完整晶体部分的分界线。以fcc晶格为例,最常。二‘。一‘,,,、~,,一一,、,、二加,‘爪1,,,八、~,.I见的是在{111}类型的面上通过操作:①告<112>类型2.“J~阵、“‘,~~曰刁~一~一一’「‘~6、““’~~滑移;②抽去一个{111}层,并使上下两岸复合;③插入一个{111}层。这3种操作均造成层错,此层错的边界即是不全位错。分别称为肖克利不全位错, 1‘,,。、0=~不Lll乙J O负弗兰克不全位错,正弗兰克不全位错,。一告〔“‘〕。一奇〔“‘〕。 不全位错复杂之处在于它必然与层错相联系而存在,所以它的形式和运动均受层错之制约。例如上述肖克利不全位错只能在{111}面上作滑移,而弗兰克不全位错根本不能滑动。除fcc晶体外,在hcp、bcc、金刚石结构及其他许多实际晶体中,不全位错是很常见的。一个全位错可以分解为两个或多个不全位错,其间以层错带相联,通常称为扩展位错。 (杨顺华)
