撞击的

Movement trajectories of electrons under complex field and state parameters when electrons return to the dielectric surface are obtained by simulation,such as impact energy and return time. Variation laws of electron movement with emergence angle and microwave electromagnetic parameters are also derived. The emergence angle of electron has significant effect on the movement of electron,and there is an emergence angle in which the electron has the maximum trajectory length and impact energy.

研究发现：电子出射角度对其运动状态有显著影响，电子存在运动轨迹最大的某一出射角度，该角度下电子拥有最大的撞击能量；微波电场幅值的增加将使电子撞击能量增加，返回时间减小，微波电场相位的变化使电子的撞击能量和返回时间呈周期振荡，这从本质上解释了电子数量在二次电子倍增过程中以微波频率两倍周期振荡的原因；随着微波频率的增加电子将由简单的类抛物线运动转变为复杂的振荡运动。

Variation laws of electron movement with emergence angle and microwave electromagnetic parameters are also derived. The emergence angle of electron has significant effect on the movement of electron, and there is an emergence angle in which the electron has the maximum trajectory length and impact energy, Impact energy will increase and return time will reduce as increasing the amplitude of electric field, and both parameter would oscillate with the phase of electric field, which can essentially explain that multipactoring electron number oscillates in twice the frequency with the increase of microwave frequency, electron trajectory will change from parabolic-like movement to complex oscillation.

破城槌 ：近战范围的攻击，撞击目标，向前撞击并造成伤害。

Because Dione is relatively small, an impact causing a 35 kilometer crater could have spun the satellite.

由于土卫四比较小，在受到比较大的撞击（撞击坑大于35千米）时它会被转动。

Since there are many craters larger than 35 kilometers, Dione could have been repeatedly spun during its early heavy bombardment.

由于土卫四表面有许多大于35千米的撞击坑，因此它在早期撞击率比较高时可能不断被转动。

A method of drop hammer impact sensitivity test for big-bill explosive was developed.

Objective To observe MRI differential diagnosis of internal impingement and subacromial impingement of the shoulder.

目的 评价常规MR成像和MR关节造影对肩关节内在撞击综合征和肩峰下撞击综合征的鉴别诊断价值。

The centrifugal acceleration, tangential speed, and normal speed can be changed individually by varying the speed of the drop. Therefore, their respective effects can be independently observed.

藉由本实验设备可成功独立分离出离心力、液滴撞击时之正向速度和切线速度，各别探讨它们对液滴撞击固体表面的影响。

According to the results of the dynamic model tests of a 100,000-ton- berthing tanker, some analyses are given as follows: the dynamic characteristic of the drum-shaped rubber fender, the impact action of a tanker on wharf under action, the possibility for resonance of tanker impact with wave action, as well as the various factors which influence the tmpact energy of the tanker.

本文根据10万吨油轮系泊码头动力状态的试验成果，对鼓型橡胶护舷的动力特性、波浪作用下油轮对码头的撞击作用、油轮撞击与波浪形成共振的可能条件以及影响油轮撞击能量的诸因素等问题进行了分析。

The results showed that the air bubble in the coup site mainly suffered from the tensile force vertical to the impacting direction and the air bubble in the contrecoup site mainly suffered from the compressive force in the impacting direction. Since the property of tensile resistance of the brain tissue is inferior to the property of compressive resistance of the brain tissue, the injury is often easier to occur in the contrecoup site than in coup site.

实验结果表明撞击点处的气泡所受到的作用力主要为压力且来自于短轴方向，即撞击方向；对冲点处的气泡所受到的作用力主要为拉力且来自于长轴方向，即撞击方向的垂直方向。
