劈裂

In the paper, we discuss on the evaluation of the crack's volume in the hydraulic fracturing.

本文对水力劈裂过程中裂隙的体积进行简单的探讨。

Following is the factors ideating with the surface of old concrete in different way ( including brushing surface , chiseling surface , cleaving surface ), adherence agent ( including cement slurry , cement sand slurry , cement slurry with the u expansion agent ), the freeze - thaw circulation times and air - entraining .

主要考察了老混凝土表面不同处理方式(刷毛面，凿毛面，劈裂面)、界面粘结剂类型(水泥净浆，水泥砂浆， u型膨胀剂水泥浆)、冻融循环次数等对新老混凝土粘结面劈拉强度的影响，以及冻融作用下新混凝土加气对粘结面劈拉强度的影响。

The Raman band is splinted into two bands when laser power gets strong enough. The Raman band shifts to the red side and shows dissymmetrical extension can be explained as quantum confinement effect. We attributed the appearance of the double bands to the non-degeneracy of the LO and TO phonons

我们对实验现象进行了初步的分析和讨论，表明拉曼峰的红移和展宽是光学声子的量子限制效应引起的，激光功率达到一定阈值时，LO和TO声子模发生劈裂，所以单峰变为双峰

The tree was struck by lightning and splintered.

那棵树被闪电劈裂了。

The relation of the water stability of asphalt mixture with the interaction of granite and asphalt was verified by freeze-thaw split test. It is found that there is a good corresponding relationship between the rheological property of granite asphalt mastic and the water stability of the granite asphalt mixture.

并通过冻融劈裂试验检验沥青混合料水稳定性与沥青和石粉交互作用能力之间的关系，发现花岗岩沥青胶浆的流变学性质与花岗岩沥青混合料水稳定性之间存在良好的对应关系。

Thus fracture velocity and length can be obtained by iterative solution of energy balance equation in every time step when loading rate is given.

在离散时间域内，特定气体劈裂作用下，能量方程迭代求解可得到裂缝扩展速度及裂缝扩展长度。

The wall specimen tests show that increasing the mortar strength, normal stress to the bed joint, and increasing the angle of the applied load, will increase the in-plane ultimate load.

而墙试体在灰缝剪力强度越大、砂浆与砖块抗压强度比值越高、横缝之垂直应力越大、施力角度越大时，试体中砖块遭劈裂的数量也就越多，而对应之极限载重也越大。

In order to investigate the improving effect of water resistance of OGFC after replacing mineral filler by cement,the mixing proportions of OGFC with different substitution rate of cement were determined firstly,subsequently immersed Marshall test and freeze-thaw splitting test were carried out according to the Standard Test Methods.

为研究水泥取代矿粉后对OGFC混合料耐水性的改善效果，首先确定了不同水泥取代率的OGFC混合料配合比，然后按照规范规定的试验方法进行了浸水马歇尔试验和冻融劈裂试验。

Lightning Behind Chimney Rock, Colorado, 1989Trails of lightning backlight Chimney Rock in southwest Colorado's San Juan National Forest.

这是在美国西南部的圣胡安国家森林公园，拖着长尾的闪电劈裂天空，照亮了烟囱石。

The existence of Kaiser effect was verified under Brazilian tests conducted on coarse-grained granite.

验证了粗晶花岗岩在劈裂试验条件下凯塞效应的存在性。
