查询词典 crack up

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。

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。

The paper also indicates that influence of vertical crack on reinforcement rustiness is smaller than lengthwise crack, concrete basicity, concrete carbonate and so on.

钢筋锈蚀是导致钢筋混凝土结构耐久性等级下降的主要原因之一，本文根据工程调查，分析了混凝土状况对钢筋锈蚀程度的影响，认为垂直裂缝对钢筋锈蚀的影响程度远小于纵向裂缝、混凝土碱度、碳化等其它因素。

Combined with the condition of crack in concrete construction, the author analyzes the causes of cement stabilized sand gravel base course crack from dry shrinkage of mixture,temperature contraction,uneven settlement of roadbed and construction quality of base course,and introduces relevant preventive and control measures for it,which to ensure highway construction quality.

结合具体工程裂缝产生的状况，从混合料的干缩、温度收缩、路基不均匀沉降、基层施工质量四方面分析了水泥稳定砂砾基层裂缝的产生原因，并介绍了相应的裂缝预防控制措施，有利于公路建设质量。

Some meaningful conclusions had been made: 1. In the test, a form of subsurface crack is relative to the sclerometer's shape, when the top of the sclerometer is sharper the crack is easier form.

在该划痕试验中，亚表面裂纹与压头本身的形状有关；当压头顶部较尖锐时，在划痕深度一定的条件下，更容易产生裂纹； 2。

The results make it known that: in the same cycle degree, the crack propagation depth of finite element is greater than experiments, the inaccuracy between expriments and computer simulation tracing is lower than 10%, the tracing conclusion is securer than the experimental one; both directions of crack propagation are not identical.

当接管区出现裂纹时，则在疲劳载荷的作用下会加速扩展，从而降低设备的使用寿命，并且可能发生一些毫无征兆的事故。因而研究并掌握接管区表面裂纹的疲劳扩展特性对于预防接管区的失效破坏具有一定的学术和工程价值。
