应变

With the method of the Lie group transformation,the symmetry of the equation governing one dimensional finite strain consolidation is discussed and,from the point of the symmetry,the feasibility to obtain the analytical solution of these nonlinear partial differential equations is discussed.

介绍了基于连续介质理论和混合物理论的大应变固结理论的发展，论述了两种一维大应变固结理论之间的差异及其一致性。

Note that as in the case of the normal strain,**, the shear strain ** is also a dimensionless quantity since it represents a radian measure.

请注意，就如正常应变**的情况一样，剪切应变**也是无量纲的量，因为它表示一个弧度的量度。

To study the different permeability characteristics of rock, transient permeability tests of limestone and diorite were carried out. The permeability evolution and the relation between pore pressure and time of rock specimens during the complete stress-strain course were investigated. The strain-permeability equations of rock specimens during the deformation and failure course were set up. Finally, the penetration mechanism of two types of rocks was analyzed.

为研究岩石不同渗透特性，对石灰岩和闪长岩进行了瞬态渗透实验，研究了岩样全应力－应变过程中的渗透率演化规律以及孔隙压差与时间的关系，并建立了岩样变形破坏过程的应变－渗透率方程，最后分析了这两种不同类型岩石渗透机理。

This angle distortion results from the rhombohedral symmetry of LSMO, when it is matched onto a cubic substrate. As the distortion angle is partially recovered in coherently LSMO films, the transition temperature T_P of the films almost approaches to that value of the LSMO bulk.

因此，菱形的LSMO匹配生长在立方单晶衬底上，除了受晶格参数失配引起的应变外，还存在另一种应变来自于LSMO匹配生长在立方衬底上引起的。

The growing characteristic of cavities in Al-Li alloy during the superplastic plane strain and double axis tensile strain is investigated and compared.

本文研究和比较了Al－Li合金超塑平面应变和双轴拉伸应变中空洞生长的特点及空洞受到抑制的程度。

The normal earth tide curve was distorted after the first strain step, and it was recovered

弦频式应变仪就是其中的一种，在该仪器的试验观测中记到了菏泽地震的应变突变。

We used solid earth tide as the reference strain, the strain data from these two instruments are basically identical.

以地球应变固体潮为参照，确定两种应变观测数据基本一致。

The peak of elastic strain energy decrease rate occurs in strain-softening stage.

峰后的应力－应变曲线越陡峭，弹性应变能降低率的峰值越高。

The accumulated elastic strain energy and deformation induced by the fault movement exceeds the strength of rock, and in sequence causes fault rupture and strata failure, and then earthquake occurs.

断裂的活动容易导致断裂及其附近岩层中弹性应变能的积累，当应变能超出岩体的强度时，就会引起断裂或岩层的破裂而发生地震。

Through calculating it is discovered that there is elastic strain energy concentration near triple junction when loading direction is parallel with triple junction, but the concentration degree is not so high.

因为应变能中包含了所有的应力分量和应变分量，能全面地反映各应力分量对三晶交点应力集中程度的影响。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
