回弹

The results show that there is a good relationbetween slope rockmass quality,which depends onrebound value,grip coefficient,apparent block sizeand ground water,and slope height and angle.

统计分析表明，由回弹值，岩块咬合系数，视块度以及地下水影响系数所建立的边坡岩体质量 BYZ(BYZ=R·E·D·W)与边坡高度，坡角有明显的相关性。

19" As the market rebounded, the strongest index for the real estate index, which is a small number of non-adherence to the market index hit another new low and take the lead in "9.19" high index; followed by small and medium-sized plate composite index, manufacturing Industry index, the pharmaceutical industry index, as well as Zero index, which had been cut,"9.19 high rebound in the region.

9.19&随着市场反弹，对房地产指数，这是一种非少数坚持市场指数再创新低，并带头在&9.19&高指标；其次是最强的指数中小企业大型板综合指数，制造业指数，制药行业指数，以及零指数，已被切断，&9.19高回弹在该地区。

Springback is one of the key defects in plate forming,which must be solved in stamping because it affects forming quality.

回弹是影响成形件质量的主要因素之一，是板材冷冲压成形中必须解决的问题。

Though in the impact process exists rebound phenomenon and the wave form becomes interrupting impulses, yett the energy loss of the mass is very low. So it is thought to link the interrupting impulses to a continuous wave form by using proper way and then to process the data by mature vibration analyzis technique.

该方法认为，尽管冲击过程中存在着&回弹&，波形成为断续的脉冲，但质量块在空中运动中能量损失很小，可以用适当的方法把它们组合成连续波形，以致我们可以用成熟的振动分析技术进行数据处理。

There are many problems in the carling forming and unloading processes such as expand and shrink of U section wall, the torsion of U section and the warp of carling head.

针对纵梁冲压成形及卸载后发生的U型截面侧壁的外扩、内缩、扭转以及纵向端头翘曲等问题，首先分析了纵梁的成形及回弹变形机理，利用仿真分析软件KMAS进行了数值模拟并采用半解析、半实验方法研究了纵梁底面翘曲，找出模具结构的最佳方案。

There are many problems in the carling forming and unloading processes such as expand and shrink of U section wall, the torsion of U section and the warp of carling head. These problems are concerned by the carling factories and do not solved for a long time. The mechanism of the carling forming and spring back is analyzed. The carling forming and spring back processes are simulated by KMAS software. The warp of carling underside is researched by half analytic and half experiment method and the best scheme is found by this method.

The method has been applied to optimize the variable blankholder force of a U-shaped part and an actual car panel.

与现有的变压边力回弹控制方法相比，大大提高了优化过程的效率和优化解的有效性。

In operation, a annular cutting knife moves forward to cut off the knife anvil (4),and when the annular cutting knife moves backward, it carries off the inner ring of the knife anvil (4), the elastic locking piece (5) is springed back and replaced.

手术时，环形切刀向前运动切断刀砧、后退时把刀砧内圈带走，弹性锁片发生回弹复位，在各种辅助机构的配合下，钉砧环便可以绕着钉砧轴发生翻转。

It was found in a high-rise building structure after fire that large-area concrete spalled at the bottom of slabs reinforced with low-alloy deformed steel bars. Temperature field of slabs during fire was determined by the ultrasonic-rebound combined method, and post-fire mechanical performance of concrete and steel bars were inspected by drilled cores and intercepted steel bars respectively.

针对某高层建筑结构低合金盘圆变形钢筋混凝土楼板火灾后板底混凝土大面积脱落的情况，现场采用超声回弹综合法确定楼板温度场，钻取芯样测试火灾后混凝土强度，截取钢筋试件通过拉伸试验检测火灾后钢筋力学性能。

Some conclusions are drawn as follows: The total tendency of socles is basin-shaped settlement which is bigger in the middle position socles than the peripheral position socles before the pile foundation underpinning. Pile foundation underpinning augments the differential settlements. After soil excavation, middle position socles rebound obviously owing to unloading action, which lessens the differential settlements between middle and peripheral position socles.

从沉降分析的结果可以看出：桩基托换前，地基总的沉降趋势是中间部位柱脚大于周边部位柱脚的&盆式沉降&；桩基础托换后，柱脚处的沉降差进一步增大；土方开挖后，由于下层土被&卸载&，中间部位柱脚处的地基明显回弹，使得中间部位柱脚与周边部位柱脚的沉降差出现了减少的趋势。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
