查询词典 oscillation

Physics The increase in amplitude of oscillation of an electric or mechanical system exposed to a periodic force whose frequency is equal or very close to the natural undamped frequency of the system.

The results show that under the complicated upper limit control logic,the upper limit depth trajectory is not a simple form,but two or more irregular forms of re-entering into the upper limit depth,or regular oscillation form around the upper limit depth.These results may be expected to provide a theoretical basis for analyzing the problem in sea trial.

仿真结果表明，在复杂的上限控制逻辑下，上限深度弹道不是一种形式，可能存在不规则的2次或多次再进入上限的弹道形式，或者存在上限附近深度规则振荡的弹道形式，这些规律为实航中出现的一些特殊现象分析提供了理论依据。

It is learnt from the correlation analysis with the EMD decomposition results of Southern Oscillation Index that the upper ocean temperature variation of the DP might be effected by the surface air pressure variation of the decadal time scale in the tropical Pacific Ocean.

与南方涛动指数的年代际时间尺度分量的相关性分析结果表明，热带太平洋海面气压场的变化对德雷克海峡上层海洋温度的年代际变化有一定影响。

Influences of different duration of oscillation,pH value,initial concentration of uranyl ion and particle size of sand on adsorption of uranyl ion on sand were studied.

应用简单土壤类似物——沙粒，模拟UO22+污染土壤的过程，研究不同振荡时间、不同pH值介质、不同初始ρ(UO22+)及粒径条件对UO22+吸附的影响。

It is hard to discern the change of sound oscillation with our hearing in general experiment for mensurating velocity of sound.

在一般测定声速的实验中，利用听觉很难辨别声波干涉形成的振动加强和减弱的变化。

However, the role of inactivation gate of sodium channel is not clear. In present study, single fibre recording in vivo from dorsal root on chronically compressed DRG model was used. We analyzed the characters of ISI series of oscillation firing of type A neurons induced by veratridine, an inhibitor of inactivation gate of sodium channel.

本研究在大鼠背根节慢性压迫模型上，利用在体单纤维记录方法，观察与分析Na通道失活门抑制剂藜芦碱引起受损背根节A类神经元放电ISI序列发生的变化特征，为了解Na通道失活门与放电型式的关系以及进一步探索放电时间型式与疼痛的关系奠定基础。

The results of computation show that this method is very effective for reducing and controlling the transverse oscillation of wave motion and for the calculation of wave particle velocity of wave motion on free surface, w...

计算表明：这种0—1混合型边界元的剖分方式，在控制和减缓波浪"横向振动"幅度及水面单元水质点波动速度的计算方面，显示出了其独到的优越和灵活之处，为时域内的波浪非线性变形计算提供了时步上的数值保证

The weak moisture convergence at the low level simulated by the Zhang-McFarlane scheme is not strong enough to maintain the structure and the eastward propagation of the oscillation.

Zhang-McFarlane（1995年）对流方案模拟的MJO振幅非常弱，而且缺乏连续的传播特征，在MJO的演变过程中弱的低层水汽辐合使MJO难以维持和传播。

When this network—the Wien Bridge—is used as a positive feedback element around an amplifier, oscillation occurs at the frequency at which the phase shift is zero.

这个 电路就是"文氏桥"，如果以文氏桥作为放大器的正反馈路径，那么当相移等于 0 的时候，就会出现振荡。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。
