劈裂

The failure of a gear shaft was analyzed by SEM analysis,macrograph,metallographical examination,mechanical test,chemical analysis and etc.

采用扫描电镜、低倍检验、金相检验、力学试验和化学分析等方法，分析了人字齿轮轴发生劈裂的原因。

The advantage of this technique is that the operation of angle-splitting ostectomy with partial masseter and buccal fat pad excision can reduce width of lower face effectively.

下颌骨体的劈裂截骨、部分咬肌和颊脂肪垫去除可有效缩窄下面部的宽度。

Necking and cleavage cracking are discussed in terms of prior concepts.

并以前面所学的观念探讨颈缩及劈裂破坏。

Nobbut one style in this second might change to another in the next second.

并基于此，提出应变集中为核心的水力劈裂观点。

By controlling the potential of the electrolyte solutions,this technique can be employed in studies formation of DNA strand breaks.CT-DNA was cleaved by adding amounts of CuL or NiL complex in the absence of chemical reagent when appropriate electrode potential(sufficiently negative or positive to reduce or oxidate metal ions) was applied.

根据获得的实验结果，CuL或NiL存在下，电解溶液的电位合适时(足够负或足够正的电位，保证金属离子的还原或氧化)，不需要加入额外的氧化剂或还原剂，同样可以切割小牛胸腺DNA，CuL劈裂能力强于NiL配合物。

Finally, the PEC-treated LEDs are packeted as the TO-Can and Lamp formal to measure the output power. The fabricated LEDs through the PEC process have 14.6% output power enhanced compared with the general LED at 20 mA operation current.

最后将基板磨薄切割劈裂成晶粒，并且以 TO-Can 与 Lamp 形式封装，量测电性资料与光学特性，发现表面结构的改变也影响发散角度，经过处理的晶粒有较大的发散角度，最终封装成 Lamp 形式的光输出功率增加14.6%。

Results show that the displacement in horizontal direction and the maximum principal stress of core wall will increase to a larger extent if the creep effect of asphalt concrete is considered.

研究结果同时也表明，不同蓄水过程对心墙性状的影响不大，心墙产生水力劈裂、剪切破坏与挠曲破坏的可能性不大。

By using Duncan-Chang E-B model, the grouting period-stopping period of a earth rock dam, and the finite element analysis of stress and strain. Split-grouting can increase the maximum and minor principal stresses at the same time.

采用Duncan-Chang非线性模型，模拟了某土石坝劈裂灌浆的灌浆－停灌施工过程，进行了应力、应变、稳定有限元分析。

The measurement results show that the minor principal stress in the rock mass around the high-pressure cavern is 5.6–7.9 MPa and nearly horizontal,the jacking strength is about 6.0–8.0 MPa,and the permeability under pressure of 7.0 MPa is less less than 1.0 Lu.

测量结果表明，测点洞段围岩的最小主应力值为5.6～7.9 MPa，最小主应力状态为近水平；测点洞段围岩的抗劈裂强度一般为6.0～8.0 MPa，围岩自身具有较强的承载能力；在7.0 MPa高压下洞壁围岩的透水率大多小于1.0 Lu。

In the neighborhood area of grouting axes, the minor principal stress increased more extent than the maximum one. The stress level was reduced and lower than before; and the stability of the earth dam increased.

劈裂灌浆可以同时增大大小主应力，在灌浆轴线附近区域，小主应力增加幅度大于大主应力增加幅度，应力水平较灌浆前降低，土坝稳定性增加。
