Web摘要: 红西断层作为红旗凹陷的边界断裂长期控制着凹陷的形成演化与油气成藏,目前对断层的识别刻画及生长模式的认识还存在诸多不足. 以地震剖面精细解释为基础,确定红旗凹陷几何学特征及边界条件,结合控制变量法进行多组构造物理模拟实验;将实验结果与红旗凹陷基底顶面构造图各项 ... WebThe. strain ellipse. is a convenient way to represent a state of homogenous strain, or the strain at a point, on a two-dimensional surface. The strain ellipse is the shape of a … Strain is not a force, but a deformation. Everything in the world—everything in the universe—deforms when subjected to stress, from the vaguest cloud of gas to the most rigid diamond. This is easy to appreciate with soft substances, where its change in shape is obvious. But even solid rock changes its shape when … See more Strain comes in two varieties. Elastic strain is the strain that we sense in our own bodies—it is stretching that bounces back when the stress is reduced. Elastic strain is easy to appreciate … See more Plastic strain is deformation that is permanent. Bodies do not recover from plastic strain.
