裂缝的

It is about equivalent to the later period of Xizhou Dynasty and in the middle-later period of Chunqiu Dynasty in era, the former is larger in scale, with the long axis direction of crack of sand parallel to the direction of the seismic fracture in the near side.

发生时代约相当于西周晚期和春秋中晚期，前者规模较大，含砂裂缝长轴方向平行于近侧的地震活动断裂方向。

The results of 3-D nonlinear seismic analysis show that, to arbitrary velocity and input direction of the design travelling wave, the aseismic safety of the joint structure in the top of diaphragm walls is reliable; all of the core and the diaphragm walls wouldn't occur tension rupture or crack; the sand lens in the overburden wouldn't occur liquefaction; the dam wouldn't occur sliding.

三维非线性动力分析表明，在设计地震作用下，无论各种波速及各种入射方向，防渗墙顶连接部位的抗震安全性较高；坝体心墙及防渗墙不会产生拉伸破坏或裂缝；覆盖层砂层透镜体不会液化；坝体不会出现滑移破坏。

So,fracture is the key to exploit the compact sandstone.

因此，裂缝是开发致密砂岩的关键问题所在。

For the sandy soil, the crack is more regular.

对于砂性土，裂缝面则多是规则的。

In addition, water gradients, crack width, permeability time, specimens kinds can also influence the self-sealing degree.

水力梯度、裂缝宽度、渗流时间、试件品种均对自愈程度有比较大的影响。

The crack behaviors under the state of serviceability are mainly studied in this ***.

本文着重研究了试验构件在正常使用极限状态下的裂缝性能。

I asked my mother to sew up this rip in my sleeve.

我让母亲缝上我袖子上的裂缝。

You've got a tear in the sleeve of your shirt.

你衬衣的袖子上有道裂缝。

The single-phase flow in fracture and cave is studied on the base of numerical computation and experiment.

用数值计算和实验的方法研究单个裂缝－溶洞中单相流动问题。

He only had a pair of slippers to wear.

他的衬衣上有一条细长裂缝。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
