查询词典 acceleration

This is because for the transition from undeformed material to deform to take place along a thin plane, the acceleration across the plane has to be infinity.

这是由于未变形的材料沿着剪切面发生变形，而且越过剪切面的加速度无穷大。

The acceleration is indispensable as a state-variable for precise analysis of the dynamic response of a drive system. This is because it represents the direct, undelayed response of a mass being moved in reaction to all the forces acting on it.

加速度是必不可少的一对驱动器的系统，这是因为它代表着直接的，毫不拖延地的群众正在反应，反应的所有部队行事提出精确的分析动态响应状态变量。

The corrosion fatigue crack growth and near-threshold characteristcsof high tensile steel HT60 were investigated by using the compact specimens underexposure to synthetic sea water. The da/dN vs △K_ relation in air may be conser-vetivel estimated for that in sea water. In the high △K region with high stressratio, owing to the acceleration of crack growth promoted by stress-induced dissol-ution, the crack opening stress intensity factor K_ represents only the result ofcrack surface in contact with corrosion products, so as to give an overestimation ofK_ at crack tip.

对高拉力钢HT60的腐蚀疲劳裂纹扩展特性和门槛值区域特性，采用紧凑拉伸试件在人工海水中进行了实验和研究，结果表明：在空气中的da/dN与ΔK_关系可以作为在海水中的da/dN与ΔK关系的一个偏保守的预测；在高应力比的高ΔK区域，由于应力诱起溶解促进了裂纹扩展的加速；该裂纹开口应力强度因子K_仅反映了裂纹表面同腐蚀生成物接触的结果，从而导致了K_在裂纹尖端的偏大的估计结果。

Also Thursday, Toyota said its large-scale recall stemming from the sudden acceleration problem would spread to Europe on an undetermined number of vehicles as well as to China.

丰田周四还声称，因汽车突然加速问题而引发的大规模召回行动将扩展至欧洲和中国，召回数量未定。

It starts from rest and falls vertically downward with uniform acceleration.

它从静止开始以匀加速度竖直下落。

Therefore, the combustion efficiency gains, so I can save 10%~ 20% of fuel consumption, instantaneous torque can be a maximum increase of 35% or more, in uniform, hard phases of acceleration, idling operating range of each have been reflected.

因此，燃烧效率提升，所以可节省10%~20%的耗油率，瞬间扭力值则可最高增加35%以上，在匀速、急加速、怠速各运转区间均有体现。

Vehicle side slip angle is considered as mapping of time series of yaw rate and lateral acceleration. A uniform design project is used to select training samples, and the relationship of the three state parameters is established through neural network.

把汽车侧偏角看作横摆角速度和侧向加速度时间序列的映射，采用均匀设计方案对训练样本进行优选，通过神经网络建立三者之间的映射关系。

Results:After we adopted uniform temperature acceleration to observe its stability laid aside for some time, we found out that the freeze - drying wa...

结果：我们采取等温加速实验法对本品放置后的稳定性进行了观察，结果表明冻干剂较水溶液稳定，存放周期延长、不易氧化。

First, the partial observability of target parameters when a single observation station moves with uniform velocity and the target moves with a uniform acceleration in the straight line is proved in theory.

首先在理论上证明了目标作匀加速直线运动，单观测站作匀速直线运动时的目标参数的部分可观测性。

The main idea of the simulation is adopting Monte Carlo method and the classical over barrier model to simulate the randomicity of the charge exchange processes between projectile and metal and the dispersing of projectile's continuum movement. In each step, the movement of projectile is considered to a uniform acceleration.

本论文模拟的基本思想是在经典过垒模型下，采用蒙特卡罗方法来模拟入射离子与固体间电荷交换过程的随机性，并将入射离子连续的运动过程离散化，在每一个步长中，将入射离子的运动近似看成是匀加速直线运动。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
