Its amount has relation with acting load. The influence on sectional curvature of bending components is the greatest one, the ultimate curvature of corroding section decrease obviously, and the sectional curvature increases rather sharply with the increase of rust rate during the process of corrosion. The anti-cracking capacity of prestressed bending R. C. components may be damage. For the convenience of engineering usage and damage evaluation of structure, this paper presents a concept of sectional damage coefficient on the foundation of experimental and treatment study.

试验与理论研究均表明，受压区钢筋锈蚀后对普通钢筋混凝土和预应力钢筋混凝土受弯构件的承载力影响均不大，但对构件的正常使用性能有较显著的影响，受压区钢筋锈蚀过程中，截面刚度有较显著的下降，挠度及受压区混凝土压应变随锈蚀量增加而增加，增加值与使用荷载大小有关；受弯构件的截面曲率所受影响最大，锈蚀后截面的极限曲率有明显的下降，在使用荷载作用下，截面曲率则随钢筋锈蚀量的增加而有较显著的增加；而预应力混凝土受弯构件的抗裂度会下降。

As the brittleness of low-k material,the traditional wire bonding parameter often lead to die pad crack or Au-AL matter bad;after used low-k material,die size,die pad opening and die pad pitch change to more little,wire change to lengther and density change to more higher,it\' s new challenge for molding and wire bonding;at the same time, low-k material also require to control the thermal stress in package.

由于低介电常数材料的脆性，传统的引线压焊参数设置将会导致焊盘碎裂以及金铝化合物不良；由于使用低介电常数材料后，芯片尺寸、压焊区域和压焊间距进一步减小，金线压焊长度和密度大大增加，这就为压焊和模塑提出了新的要求；同样由于低介电常数材料的应用，对封装体内部的热应力的控制也提出了更高的要求。

Admixing JM-SRA and permeating AS20 can all effectively reduce the dry shrinkage of RCC, and admixing JM-SRA have better results: it can reduce 60% dry shrinkage at 1d~3d, and reduce more than 35% dry shrinkage at 90d.

抗裂性能试验和抗裂指标分析表明：减缩剂的掺入可减少碾压混凝土早期塑性收缩裂缝，提高碾压混凝土的抗裂性能。

Admixing these two shrinkage reducing agents can all obviously improve the physical mechanics performances of RCC such as compressive strength, cleavage crack tensile strength, axial tension performance, axes compressive strength and static pressure modulus of elasticity.

盗窃罪 他弯角和他休息如果他让他们拿走他的激情，他的痛苦，他的宽限期他喷出， 1000黑色花朵爆炸成蝶，因为他们再度远离扯裂出来，带他们，烧伤，以煤，因为他们粉碎，并留下什么这类似于一个民族的灵魂，一名男子看到他麻木，见他压死扯裂出来，带他们烧伤，以煤，因为他们粉碎，并留下什么这类似于一个民族的灵魂，一名男子让他们麻木，让他们压死（让他们麻木，让他们压死）发生火灾内其中太多次了他s燃烧，并出现，他flails 针对汹涌大潮没有更多的两岸一切你永远不想看到的，看它在他的眼中再一次，再一次爬下来试水，我的手的感觉，他们再度生锈以外，嗯，嗯，嗯，所以我的步伐，黎镑左右，像羔羊前屠宰 i当地雇员留在这里，只要你让我，决策取得了明显的，所以我将返回我开始i黎巴嫩镑在这里呆当即时通讯完毕i黎巴嫩镑以外向何处去

From the microstruture observation, this dilatancy produced is clearly associated with a change from crystal plasticity plus minor cataclasis (formation of closed intragranular cracks) at high pressure (20MPa) to crystal plasticity plus significant cataclasis (involving axial cracking, intragranular cracking, crack opening and shearing) below 10MPa.
