用压力容器的弹性模量定义损伤变量，进而建立了弹性模量和载荷循环次数之间的关系式。

It is found that the wing crack extend along a curved path and gradually approximate to the line which passes the middle point of the main crack and is parallel to the direction of maximum principal stress.

采用数值和试验的方法对翼型裂纹的扩展路径进行分析，发现单轴下张开型裂纹的翼型裂纹的扩展路径逼近于过原主裂纹中心点、平行于最大主应力的一条直线。

If θ=0?＃, it means that whisker axis is perpendicular to crack face, the energy dissipation caused by whisker-bridge join in zone of crack end achieves its maximum and the reintoughening effect of material achieves the best of all; along with growth of angle θ, the maximum principal stress in the matrix of whisker roots increases, when it achieves its limit, the whisker will be broken and orientation effect will be weakened.

当添加晶须与裂纹面法向形成角度θ时，随角度θ的增加，裂纹尖端拉应力增加。当添加角度较大时，晶须根部基体承受了较大的应力，易遭到破坏性崩裂。同时，晶须内部主应力与晶须轴向之间的角度也随角度θ的增加而增加，造成晶须折断，致使造成晶须拨出的体积分数φap减小，降低了增韧效果。

In order to control the surface crack damage of huge thick collapsible loess caused by mining effectively,the distribution rule of stress-strain in top interface of the base rock and the relation of which and the surface crack were obtained using the probability integral method.

为了有效地进行采动巨厚湿陷性黄土地表裂缝损害的控制和治理，在对西部几个矿区开采地表裂缝破坏调查的基础上，应用概率积分法计算基岩顶界面的应力应变分布规律，分析其与地表裂缝的关系，研究开采引起黄土层地表裂缝产生的机理。

Detailed study was also preformed on remedial and maintenance methods for broken crack, advanced countermeasure based on the grade of broken crack.

同时对水泥混凝土路面的裂缝的维修处理方法进行了系统的研究，根据裂缝的破坏程度，总结提出了相应的处理措施。

Usually, layer and vertical crack are caused by moulding,and horizontal and reticulate crack are caused by sintering .

通常层裂和竖向裂纹是机压所致，横向裂纹和网状裂纹是烧成造成的。

The results indicate that multisource fatigue core appear in the axe surface non-metallic inclusion distributing place by bending and retortion circle stress; The crack selevtivity expand to form the fatigue step along inclusion distributing route in the cut stress; The crack celerity expand to form the fatigue striation when puff part adequacy long in the positive stress.

结果表明：辊轴在弯曲、扭转循环应力作用下，表面非金属夹杂物分布位置出现多源疲劳核心；在切向应力作用下裂纹沿夹杂物分布路径选择性扩展构成疲劳台阶；当断面张开部分足够长时，在正向应力作用下发生快速扩展，微观形成疲劳辉纹。

It lifted its great branches with pomp and beauty,asit lifts them still,but the storm had already twisted thetrunk a little,and time had given it a crack;now wind andweather have laid earth in the crack,where grass and greenthings grow,yes,even a little rowan tree has planted itselfthere.

这是某个时候的情形；但是现在它是孤独和沉寂的。"孤独的、无能的、可怜的拉斯木斯"——大家这样叫他——住在这儿。他是在这儿出生的。他在这儿玩耍过，在这儿的田野和篱笆上跳跃过。他小时候在这个池子里拍过水，在这棵老树上爬过。
