And the error variable was solved analytically making use of"Project Point". Then the traditional PD controller and gain-scheduling fuzzy PD controller were designed to realize path following of parafoil system.

同时，基于翼伞系统基本运动特性，提出了一系列有针对性的控制策略，其中重要的一条是，将平均风的影响在轨迹归航中修正，而大气紊流的影响作为干扰由控制器来补偿。

On the basis of the mechanism of dust collection by fog-drop and the theory of turbulance pulsation,an industrial test was made on the effect of a wet vibrating fibre-grid dust-removing and cleaning device.

Two-fluid large eddy turbulence model is applied to research the movement of the sand clouds in quiescent water.

本文采用双流体大涡紊流模型对静水中泥沙云团下落过程进行了研究。

The damage of the pipes is accumulated in a long time, the leakage of elbows , tee joint T, even in the loop of tube union should be occurred after 3 to 5 years usage, but it's fatal to irrigation system.

同时如果喷灌使用者没有按照使用规范使用喷灌系统，将会管路摩擦损失急剧增加，产生的后果是：喷头达不到工作压力、管路水流动速度过高产生紊流而损坏管道，损坏管路的现象虽然是长时间积累的，但是有些球场在3～5年后发现弯头，三通等管件出现漏水，甚至在活套管接头处产生漏水，这对喷灌系统是致命的

To obtain more uniform temperature distribution and relative lowest temperature over cross section of the rotor, on the basis of test data of a given example of a 150MW turbo generator with air coolant, numerical solution of two dimensional modelling equations of air turbulent flow and heat transfer in and between cooling duct and rotor were carried by the Finite Volume Method at condition of varying configuration parameters of sub slot, the number of winding's cooling ducts and center distance of them, and the diameter of slot wedge.

为了能够得到转子截面较均匀并且最高温度值较低的优化温度分布，文中在150MW空冷汽轮发电机转子实验研究基础上，改变副槽的几何形状、径向通风沟的条数及间距、槽楔出风口直径等几何量，采用有限体积法求解转子本体及通风道内空气的传热及紊流流动等二维离散方程组。

Assumed that the coherence of the wind load in vertical is the same to the wind speed, the auto power spectrum and cross power spectrum of the wind load on the tower is formulated. Futhermore, the analysis shows that the contribution of the turbulence is about equal to the vortex shedding for the cross-wind motivation.

基于风荷载竖向相干性与风速相干性一致的假设，得到输电塔不同高度的风荷载自谱与互谱，并分析输电塔横风向激励的组成，识别出紊流激励部分与旋涡脱落激励部分约各占一半。

The flow resistance of Ice slurry increases if the pipes obliquity increases. That means the ice slurry that in the level pipe has the largest flow resistance, the reason is: the gravitation make the flow became more and more foul-up, accordingly, lead to the increase of flow resistance. Sixthly, introduced all of the preparative tasks before we began the experiment, because we met many problems during the test, we had our own methods which could solve these problems. In this paper, problems and these methods were introduced.

随着管道倾角的增大，二元冰的摩擦阻力减小，也就是说相同条件下水平管道内的摩阻最大，这是因为重力的影响导致管道内二元冰和乙二醇分层现象更加明显，从而导致紊流程度增大，最终使得摩阻增大；第六，对二元冰蓄冷空调系统运行前的准备工作进行了介绍，由于在试验过程我们遇到了很多问题，针对这些问题，我们有自己的方法和解决办法，本文介绍了这些问题和相应的解决办法。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
