撞击

Had nothing to do with the formation of ocean basin.

第四段提到陨石撞击与海盆形成的关系，吉瓦里认为，陨石撞击导致海盆的形成，作者对此提出了质疑，但无法推出两者无关，故D项&与海盆形成没有任何关系&错误。

If the square strikes the perimeter of the playing field, or one of the simulated paddles, the square ricochets based on the angle of the impact.

如果球撞击到游戏区域的周边或者某个球拍上，就会按照撞击的角度被反弹。

The velocity distribution function is modified for impact of molecules in a microbeam given by Kadar.

考虑到谐振微梁振动时，撞击在微梁两侧的分子数目和分子速率分布的差异，对 Kadar 等人提出的撞击微梁的分子速率分布函数做了修正。

The strike plate is delivered with fasteners that permit it to flex so that

撞击板由紧固件拖动伸缩，所以当门被关闭时，撞击板自动与磁场匹配，磁力就会发生作用，牢牢的将门锁上，切断磁体的电，门就会打开。

The Style X body design has special geometry and plate configuration to allow each plate to strike the stop pin in its center of percussion.

X类型阀体结构具有特殊的几何结构和阀瓣配置，使得每个阀瓣撞击在其撞击中心的止动销上。

The results are:(1) Samples without straight radial grain have more hits and increasing faster than samples with straight radial grain, but before fracture hits count is not much different.

最后得出以下结论：(1)径向纹理不通直的试件比通直的声发射撞击数要多，而且增加的趋势较快，但是在试件断裂前，声发射撞击数相差不大。

This paper, based on the full scale bird impact tests, and detailed analysis the results of high speed photography, dynamic strain gauge, puts forward that triangle pulse simply model could be simplified by bird impact loading of inclined impact process .

对飞机风挡进行全尺寸鸟撞试验，通过对鸟弹撞击风挡玻璃过程高速摄影、动态应变测量等试验结果的分析，提出了斜撞击过程的鸟撞载荷可以简化为三角形脉冲的简化分析模型，利用该简化载荷模型对风挡玻璃鸟撞进行的有限元分析，结果和试验结果很好地相符

More than 200 people have been killed worldwide as a result of wildlife strikes with aircraft since 1988, according to Bird Strike Committee USA, and more than 5,000 bird strikes were reported by the U.S.

据美国飞鸟撞击协会提供的数据显示，自从1988年以来，全球由于野生动物与飞行器相撞已导致超过200人遇难，另据美国空军的报道仅2007年一年里就发生了超过5000次的飞鸟撞击事件。

The results showed that the damaged starch contents of hard wheat were 20% higher than that of soft wheat under the same processing condition, and the damaged starch contents would be increased ...

研究结果表明：硬麦加工后淀粉破损率高，而软麦则相对较低，硬麦粉的淀粉破损率较软麦粉高出 2 0 %左右；面粉越细则淀粉破损率越高；研磨道数越多，研磨强度越大，淀粉破损越严重；齿辊所造成的淀粉破损程度要比光辊为重，但差距不是很大；撞击机在正常生产时对淀粉破损影响较小，如反复撞击也会使破损淀粉增加，但其影响程度较研磨强度缓和。

At the same time, pattern recognition has been used for abstracting characteristics、predicting the life and evaluating the properties of engine. This research contributes toward global diagnosis for the diesel engine in eight ways.(1) Put forward"the Arithmetic of distinguish the period automatically using auto-correlation method";(2) Separate the waves of continuous knocks using WV distribution;(3) Propose"the logarithmic spectrum approximate method"to analysis the response of the knock between the steel and steel;(4) Discuss the relationship between the time-frequency distribution and timescale distribution in detail, and give the principle of classification;(5) Use the wavelet method to analysis the pressure signal of exhaust、suction;(6) Use the shape of vibration signal to analyse the working situation of cylinder;(7) Use the pattern recognition to select the good samples and abstract the effective characteristics;(8) Develop the model of total properties evaluation and life prediction.

本文在广泛的、深入研究的基础上，应用多种信号处理手段来分析处理数据，同时利用模式识别方法对故障的特征提取、寿命预测以及性能评价作了探讨，本文进行了以下几项工作：（1）提出了基于自相关自动周期识别算法的柴油机振动信号预处理策略；（2）提出了基于WVD分布的连续撞击响应信号的分离策略；（3）提出了基于对数谱拟合方法的钢—钢撞击响应求解模型；（4）提出了基于波形分析的非正常燃烧振动信号的诊断模型；（5）提出了基于小波细节信息的进气压力信号和曲轴箱压力信号的诊断模型；（6）提出了基于小波近似的喷油正时信号中燃烧位置的自动定位；（7）提出了基于统计模式识别方法的故障诊断知识的自学习与自组织策略；（8）提出了基于特征压缩思想的柴油机总体性能评价及寿命预测模型。
