The analyses show that the break of the aerodynamic force causes the disturbance.

分析认为，空气动力在控制过渡过程中发生突变导致了这种扰动的产生。

TILT ROTORCRAFT : An aerodyne which derives the whole or a substantial part of its lift for vertical or hovering flight by tilting rotor upward to a position substantially vertical, and in forward flight derives its lift from rotors and/or wings, and is capable of autorotation in the event of power failure.

倾斜旋翼飞机：一种旋翼机，垂直或悬浮飞行时，整个或其中相当一部分之爬升力源自倾斜旋转翼使上升到一个极度垂直的位置，而在向前飞行时，爬升力源自旋转翼和/或机翼，并有能力在发生动力供应中断时自动旋转。

No one can see into the back rooms of the clerical establishment or into the bunkers of the Revolutionary Guard.

Moreover, human activities play a more and more important role in the development of tidal flat. The concentrated coastal engineering change the dynamic environment of the tidal flat, and the exploitation of oil, natural gas and groundwater results in surface subsidence in the coastal area. In addition, sea level rise and the accompanied increase of storm surge frequency and intensity, will strengthen the erosional process, reduce the tidal flat area, coarsen the sediment, made the slope steep, and cause other environmental effects.

人类活动的环境效应对渤海潮滩发育的作用越来越明显，环渤海地区密集的海岸工程将改变原始的潮滩动力环境；石油、天然气、地下水的开采会导致海岸带发生地面沉降；海平面上升以及与其相伴随的风暴潮作用频率与强度的增加都将会使渤海潮滩的侵蚀过程加强、潮滩面积缩小、滩面物质粗化、坡度变陡，并产生一系列的相关的环境效应。

According to this research method,we can reasonable interpret individuation character of cognition.View on cognitional subject,cognition is the process that subject analyzes,selects and synthesizes the information of object base on the frame of reference of subjective information.

1(1)认识论是对人类认识的哲学反思，这一哲学反思首先触及的必然是关于人类认识的普遍性和一般性问题，即人类认识的类特征问题，如认识的本质、认识发生的一般模式、认识的发展动力及其规律等。

Results show that existence from strong convergence of water vapor and the conditional convective instability in the middle and low troposphere probably provided the suitable environment for heavy rainfall.

分析表明，对流层中低层水汽的大量集中以及对流不稳定条件的存在可能对此类系统发展提供了有利环境，对其启动的机制作了初步的讨论，认为地形的动力强迫和地面冷锋以及低空急流扰动可能对此类系统的发生发展起了触发作用。

Based on the equilibrium equation of an arch element the cubic nonlinear dynamic model with second order is established and the nonlinear differential dynamic system without constant term is obtained through a transfer process of T=U+b. Hence three fixed points and the homoclinic orbits are found. The critical condition of the chaotic vibration of the elastic arch is given by using the method of Melnikov function. The numerical results of the stationary and chaotic motion are given and discussed.

首先利用拱的单元平衡方程建立了拱的二阶三次非线性动力学模型；然后通过变换使方程转化为不含常数项的非线性微分动力系统，并由此得到无扰动系统的3个不动点与同宿轨道；再用Melnikov函数法给出了发生混沌的临界条件；最后给出了该系统出现定常运动和混沌运动的数值结果。

The colonializing structure actualized a dichotomization of modes of thought. This is in great part one of the consequences of negotiations, conflicts, and cooptations among elites, and transformations in those dynamics over time.

这在很大程度上是协商，冲突以及合作的后果，在随着时间而发生转换的动力之中的协商，冲突以及合作。
