断裂的

There are four kinds of fracture ways of 7075/SiC composite under high-temperature compression, which are the evulsions of SiC from the matrix due to forming cavity near the interface and intensive phase , ductile fracture of the matrix due to the nucleation of cavity near the interface , the fracture near SiC particulate coacervate and brittle fracture of the SiC particulate.

喷射沉积7075/SiC复合材料高温压缩时的断裂方式主要有四种，即空洞在增强相与基体界面处形成而出现增强相从基体中拔出的现象、空洞在基体中形核长大而引起基体的延性断裂、颗粒团聚处的断裂和颗粒的脆性断裂。

Analyzing the MS4.8 earthquake on May 17, 1999 in Wanning coastwise, it is suggested that this event characterized by isolated type, and the seismogenic fault is the subsidiary fracture in the NE strike between the Xinglong-Longgun fault and the Qiongdongnanhai fault, which make a feature of strike-slip.

对1999年5月17日万宁近海MS4.8级地震进行了总结。分析认为，这次地震属孤立型，发震断层为NE向的兴隆-龙滚断裂和琼东南海断裂之间的次一级断裂，具有走滑特征。

Nano-Fe_3O_4 can induce DNA single-strand breaks without significancy and can not induce micronuclei formation and percentage of apoptosis. Nano-Fe_3O_4 can aggravate the effect of CdCl2 on DNA single-strand breaks and chromosome damage in HepG2 cells. They showed synergistic effects on DNA single-strand breaks after the data were statistic analyzed.

结果发现CdCl2能引起DNA断裂损伤、微核率的增加和细胞凋亡率的增加；nano-Fe_3O_4能引起DNA断裂损伤增加，但无显著意义，未引起微核率和细胞凋亡率的增加；nano-Fe_3O_4能加重CdCl2的对细胞DNA断裂损伤和染色体损伤，且二者联合作用对DNA断裂损伤的结果经统计分析认为有协同作用。

As a result these types of fibre not only keep their own fine traits,but also own good conglomerating structure ,crystal limit ,calorifics performance and mechanics performance. Compared with the ordinary fiber ,the neatness of high-contracted polyester fiber increases and it s diameter also increases.

在力学分析方面：我们得到阳离子可染的涤纶纤维的于态断裂比强度较一般涤纶棉纤维的有所降低，断裂伸长反而上升：高收缩涤纶棉纤维干湿态的断裂强力和断裂伸长都较一般涤纶棉纤维的有所降低。

In addition, coseismic Coulomb stress changes also have great influence on aftershocks distribution.

同时，由于鲜水断裂带不同断裂间的相互作用，发生地震的断裂在其相邻的断裂上产生同震库仑应力增加，使下次地震发生于其相邻的断裂上，这也可能是鲜水河断裂带地震沿带南北迁移的重要物理机制。

After the addition of carbon, the microhardness in the grain boundary is about 150 MPa higher than that in the grain. The fracture type of pure Mo is intergranular fracture, the grain boundary strength of Mo-C alloy is strengthened due to the addition of carbon and the fracture type is changed to transgranular fracture, transcrystalline fracture and a large number of cleavage planes and steps are observed on the bending fracture surface. But if the carbon content is too high, the carbide precipitation will be severe at grain boundaries and is deleterioated to the ductility of the alloy.

添加碳后，合金的晶界显微硬度比合金的晶内显微硬度高150MPa左右；纯钼的断裂方式以沿晶断裂为主，添加碳后，由于合金的晶界强度得到提高，合金的断裂方式变成以穿晶断裂为主，断口上有大量的解理面，具有明显的河流状花样和解理台阶，且塑性越好的断口，撕裂岭也越多；当添加的碳含量偏高时，在晶界处产生了大颗粒的碳化物，这种大颗粒的碳化物会降低合金的塑性。

By research for deep faults and igneous rocks related to CO2 gas fields, the author considers that magma is the carrier for CO2 gas migration, while the development of igneous rocks is an important sign of the synchronous fault spatio-temporal activity. The 'migration' is one of the most important elements for mantle source CO2 gas accumulation, which means that there are deep faults connected to the mantle, directly or indirectly, and fault activity must be consistent with CO2 gas migration in space and time.

通过对与CO2气田有关的深大断裂、火成岩进行综合研究认为，岩浆是CO2运移的载体，火成岩的发育则是断裂时空同步活动的重要标志，幔源CO2气的成藏要素最为重要的是&运&，即要有直接或间接与地幔相连的深大断裂，而且，作为一条断裂通道的活动要时空同步。

Because the area on the east part of the Anren county seat is near the regional primary subduction - fault, namely the NNE - trending Chaling - Chenzhou fault, the Wufengxian - Tiesitang NW- trending fault had little strike -slip measure, so the derivative stress and traction were smaller, and at the same time the regional NWW- trending principal stress was stronger, which produced NNW -trending folds.

安仁以东由于紧邻NNE向茶陵一郴州主俯冲汇聚断裂，NW向断裂走滑量相对较小，派生应力与牵引效应小，而区域NWW向挤压应力大，从而于断裂两侧均形成与区域构造线一致的NNE向褶皱。

The faults include the fracture of saddle support mat , the breakdowns of saddle support bolt and pin spindle.

其中，鞍座底板断裂、鞍座连接螺栓和销轴断裂，通过断口形貌和受力分析，判断故障原因为典型的疲劳断裂；大小齿面磨损变形严重是齿轮硬度不足、齿面接触应力超过材料抗剪屈服极限及润滑方法不当造成。

The faults include the fracture of saddle support mat, the breakdowns of saddle support bolt and pin spindle. Based on the analysis on the fracture and surface, the fault causes are analyzed, for the conclusions of the normal fatigue fracture, as well as the deficient gear hardness, higher contact stress of tooth face than the yield limit under shear of material and improper lubrication method, which bring serious abrasion deformation of tooth face.

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。
