The modern structural pattern ofthe area consists of three synclines and three anticlines, a group of strike faults and a group of transcurrent faults, as well as some downfaulted basins; 8. The blue schist belt, which distributs at the northern part of the area, has a genetic relationship with the decollement plane between Yaolinghe Group and Doushantuo Formation.

晚元古代扬子板块北缘由被动大陆边缘转化为主动陆缘；7、本区的现存构造格局，由近东西向的三个复式向斜加三个复式背斜，一组走向断裂加一组横向断裂以及若干断陷盆地构成；8、本区北部的蓝闪石类矿物成带分布与耀岭河群与陡山沱组之间的层间滑脱面有关；一百五十多个白云母b。

Further more, except the detachment-type fold in depression formation, the inversion structural styles can be subdivided into five types: reviving type, forward-expanding type, backward-expanding type, tyrannizing type and truncated type according to the mode of association of the thrust faults and the early normal faults.

进而将反转构造样式除坳陷层滑脱褶皱外，依据反转过程中形成的逆断层与早期伸展断层的组合关系归纳为五种类型：复活型、前展型、后展型、欺压型、截断型。

The arrowhead indicates the distal attachment of the superficial medial collateral ligament, which has been avulsed from its tibial attachment.

箭头所指为内侧副韧带浅层的远端止点，已从胫骨附着点上撕脱。

The thickness of the alloying layer is 80μm in the decarbonizing and then surface alloying, but only 15μm in the surface alloying directly. The content of cobalt which doesn't form carbide doesn't have a great difference in two processes, but that of tungsten and molybdenum make a great difference.

在两种渗金属条件下，表面合金层的非碳化物形成元素Co含量差别不是很大，而强碳化物形成元素W和Mo的含量却有着显著差异，直接渗金属的，表层W和Mo含量几乎为零，而脱碳后渗金属的，表层W和Mo总量最大达到6%左右。

When solid solution occurs at 1 030-1 230 ℃,the room temperature impact value of steel is increased with solution temperature,and the depth of decarburized layer and grain size are increased.

在1030-1230 ℃固溶时，试验钢的室温冲击功随固溶温度的升高而增加，表面脱碳层深度和晶粒尺寸则随之增大。

The results show that the reduction of free height of steel 44Si2CrV spring under compressive stress 900 MPa consists of two parts: plastic deformation of surface decarburized zone to hinder elastically deformed internal material recovering, making up 84% of total reduction of free height and creep of steel at ambient temperature makin...

结果表明，44Si2CrV钢弹簧在900 MPa的应力下压缩72 h，自由高度的缩短由两部分组成：表面脱碳层的塑性变形，造成对内部材料的牵制而使部分弹性变形不能恢复，由此所造成的弹簧自由高度缩短占总变形量的84％；钢的室温蠕变，占自由高度缩短的16％。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
