In the process of wave slamming, the impact pressures with short duration and high peaks occurs when the waves hit the subface of the structure, which causes the destabilization of superstructure and the fratigue failure of joints.

在波浪冲击过程中，当波峰刚接触到建筑物底面时会产生历时很短但强度极大的冲击压力，这种极强的冲击荷载会引起建筑物上部结构的失稳或造成结构连接处的疲劳破坏。

Under confused sea condition, the structures may subject to very strong w ave impulsive 1oad due to slamming by the wave with significant crest when waves propagate underneath the structure and surge up to its subface. Previous studies indicate that impact pressures are characterized by an initial peak pressure of considerable magnitude but of short duration occurs, followed by a slowly-varying uplift pressure of less magnitude but of considerable duration, and which typically is first positive, then decreases to zero and becomes negative, In hostile sea state, the peak pressures may cause the damage of the horizontal members of the structures or make the whole superstructure collapsed.

若这些海上建筑物的上部结构底高程较低，在恶劣海况下当大波浪在其面板下面通过并与之接触时，面板下面除了作用有强度变化较缓慢的波压力外，在波峰刚接触到面板时尚存在着历时很短但强度极大的冲击压力，这种极强冲击荷载会引起建筑物的整个上部结构失稳或造成局部破坏。

However, life organism bilks the environment condition with living to be however in constant change, contain very big uncertainty, this always is in frequent wave motion with respect to the crop that decided produce and quality in, the impact that bears natural risk is big.

然而，生命有机体赖以生存的自然环境条件却在不断的变化之中，带有很大的不确定性，这就决定了农产品的产量和质量总是处于频繁的波动之中，受自然风险的影响大。

Sings the sound wave which the sympathetic chord is refers sings when sound production the breath impact vocal cord vibrates produces, through the vocal cord around muscle, the cartilage and the air transmission, causes the phenomenon which the mouth, cavity body and so on in the chest air produces resonates.

歌唱的共鸣是指歌唱发声时气息冲击声带震动产生的音波，通过声带周围的肌肉、软骨和空气的传递，使口、头、胸等腔体里的空气产生共振的现象。

Shapes of microvoids in OFHC Cu and pure Cuare in difference. OFHC Cu target spalled under electric gun driven driven two stage metalflyer impact loading, the velocity profiles of rear surface were measured by VISAR. The spallstrength and debris size are according with the reported data and wave propagation law.

纯度不同的铜中微孔洞分布形貌存在差异，同时开展了电炮驱动二级飞片撞击无氧铜靶层裂实验，采用VISAR测量靶后自由面速度历史，测量的层裂强度和层裂片厚度与文献公布规律和冲击波传播规律基本符合。

Bridge pile foundation in practical engineering are not only subjected to static load, but also subjected to wind loads, wave impact, seismic loads and other dynamic load.

在实际工程中，桥梁桩基不仅受到静力荷载的作用，而且还受到风荷载、波浪冲击力、地震荷载等动载的作用。

Afterwards, dynamic tests to machining center were processed by using sine wave excitation, pseudo random excitation and impact experiment methods.(3) The frequency-domain parameter identification method was used after the experiments, through which system mode parameters, system characteristic curve and system mode shape were obtained.

运用频域模态参数识别法，得到了系统的模态参数，绘制出了系统的特性曲线，并得到了系统的振型；对所得结果进行了模态拟合验证，较好地揭示了系统的系统特性，为动态优化设计奠定了基础。

In this paper, the commercial software FLUENT is used to calculate the viscous flow field around a ship with Twin-skeg, without taking into account the impact of wave-making resistance.

文中利用商业软件FLUENT，在不考虑兴波影响下，对各航速下的双尾船粘性流场进行数值模拟。
