断裂的

The results show that the main reason is many little cracks exist,and heavy reticulation structure,inclusion, coarse grain and side decarburized stucture.

结果表明，其发生断裂的主要原因是存在较多的小发纹，加之较严重网状组织、夹杂物、晶粒粗大和边部脱碳组织，在机械加工力的共同作用下，导致轻轨发生断裂。

A macro and micro and chemical element analysis was made on fracture of ruptured coupling bolts,torsion test was performed and stress analysis and calculation were made,the results show that when the steam turbine had failure,MP-LP rotor coupling bolts and generator-exciter rotor coupling bolts failure were classified as overload shear fracture with partial deformation .

对215MW汽轮机断裂的对轮螺栓做断口宏观、微观分析，化学元素分析，扭转试验及受力分析计算，结果表明汽轮机组在事故中，中压-低压转子对轮螺栓和发电机-励磁机转子对轮螺柱的失效类型为：过载剪切断裂，同时局部挤压变形，这是由于事故过程中轴系受到冲击扭矩作用而引起的。

ABSTRACT In this thesis, the microstructure, the in situ tensile fracture processes and the mechanism of deformation and fracture of the SiC whisker reinforced aluminium composites made by a squeeze casting method were studied by means of SEM, TEM, HVEM, AES, HREM, electronic tensile machine and magnetic tape recorder. The dislocation theory and the complex function method were also used during analysis.

本文利用扫描电镜、透射电镜、高压电镜、俄歇谱仪、高分辨电镜、电子拉伸机和磁带式记录仪等设备和技术以及位错理论和复变函数方法研究了由高压凝固铸造法制备的碳化硅晶须增强铝复合材料的显微组织、动态拉伸断裂过程以及在特殊条件下变形和断裂的规律。

The mechanics condition of ductile fracture of pressure vessel materials and their relations to the fracture criteria were investigated based on the micromechanics .

应用细观力学的观点分析了压力容器材料韧性断裂的力学条件，并考察了其与断裂参量的关系。

Their infrared spectrum changes under UV-irradation and in the heating process have been monitored by ATR-FTIR. Then the aging mechanism has been induced by the infrared spectra before and after aging and their difference spectra. In the condition of UV-irradiation, the polyurethanes degrade to quinoid structures or azo-compounds, which is why polyurethanes' color can easily become yellow.

在紫外线照射下，聚氨酯类有机高分子涂料降解生成偶氮化合物或醌式结构，这也是聚氨酯老化颜色易变黄的原因；丙烯酸类有机高分子涂料降解机理为酯基断裂、形成稳定性较好的内酯，同时伴随侧链断裂的反应。

Further more, the fracture possibility is analyzed with fracture mechanics after the stress calculation of local high stress area around the bolt hole in shell flange and the measurement of fracture toughness of gray cast iron. The improving structure of bolts connected head and shell flange is brought forward.

此外，在计算获得缸体法兰螺栓孔局部高应力区的应力水平后，由断裂力学分析发生脆性断裂的可能性，并提出烘缸缸体与缸盖联接结构的改进方案。

The EW, SN and NE strike fault are the major host structure, and the junction of several faults is the favored place for mineralization.

EW、SN和NE向断裂是主要的容矿构造，多组断裂的交汇处是矿化的有利部位。

Au-rich magma intruded along the crust faults ascendingly. The gold deposits were formed in 145 Ma transitional period from compression to extension, corresponding to the period of large-scale delamination of the lithosphere.
