Accurate station keeping is demonstrated in experiments with our four-DOF underwater vehicle and the observed target which is a regular tetrahedron with four ball-like culminations in our indoor water tank.

悬停定位具有两个特点：首先，它是一种动力定位，即在定位传感器的引导下，依靠自身的动力，在控制系统的指挥下抵抗外界扰动而保持某一位姿；其二，它是一种局部定位，水下机器人相对作业目标的运动空间范围一般不会很大。

In view of the key problem of subminiature underwater robots, structural improving,control algorithm and underwater experiment is studied. They can be described as follow: Firstly, the subminiature underwater robot should be compact in size and low cost, for which, it is difficult for us to control its balance. So that, a new kind of piston--style ups and downs system was invented, which can keep the underwater robot horizontally suspended in the water without driving force.

中文摘要本文针对超小型水下机器人在运动中存在的问题，设计了一种新的超小型水下机器人的沉浮结构形式，着重研究了其运动学动力学性能、探讨了相应控制算法、进行了水下试验，具体研究内容如下：首先，超小型水下机器人由于体积小重量轻，在水中沉浮时悬停平衡控制困难，为此进行了一种新的活塞式沉浮系统设计，该系统使水下机器人能够在无动力驱动的情况下，使其呈水平状态稳定悬浮在水中。

The selectable equipments are rotor mast aiming system, two pods with 2 TOW missiles for each, Blackhole infrared suppresser, two pods with 2 Stinger missiles or other types of air-to-air missiles for each, FLIR system for pilot, AN/APR-39(V-1) radar warning system, fuel tank on hardpoints, advanced avionics and mission equipments.

旋翼轴瞄准具可将视频信号输给飞行员的电视显示器。旋翼轴瞄准具备激光测距仪。为了不被敌人发现，"防御者"Ⅱ直升机可借助旋翼轴瞄准具在树木或地形后面进行隐蔽悬停，而且还能观察战场远处的情况。只要稍作改装，就可安装为OH-6A研制的标准轻型航空电子设备。

Telstar was launched in 1962 and it was followed rapidly by other satellites of increasing sophistication, notably Early Bird I, the first commercial communication satellite, which was launched in 1965 and is hovering some 22,300 miles above the Atlantic.

在一九六二年发射了"电星"通信卫星之后，紧接着又发射了几颗更先进的通讯卫星，其中最著名的是"晨鸟一号"。这第一颗商业通信卫星是一九六五年发射的，现在正悬停在大约22300英里高的大西洋上空。

By volitional effort was decided to inject in the process of the game hover-boards - hovering above board, like those we saw in the film back in the future.

通过努力，意志决定过程中注入的游戏翱板-悬停局一样，我们看到在电影回到未来。

The Peugeot 307 loop reflects the profile of that specific car but also seems to hover weightlessly above the ground.

标致307环，反映了剖面的具体车，但似乎也悬停weightlessly高于地面。

A theory of aeroelastic stability of hingeless rotor blade in hover by using the Galerkin weighted residual finite element method is developed in this paper.

采用伽辽金加权余数有限元素法发展了一种悬停状态下无铰旋翼桨叶气弹稳定性的分析方法。

In the method ,the blades are treated as rigid ones with offset and spring restrained hinges and with structural coupling between flap and lead lag motion for the purpose of being applicable to hingeless or starflex rotors .

采用带外伸量及弹性约束的当量铰桨叶模型，考虑了旋翼挥／摆结构耦合及动力入流非定常气动力，建立了悬停状态旋翼／机体耦合动稳定性分析方法，适用于星形柔性及无铰式等旋翼系统。

The method used here has accounted for the chordwise and spanwise noncompactness effects of the blade surface pressure,the blade-to-blade loading correlations, especially the nonisotropic and non homogeneous turbulence field due to distortion during the rotor in-flow process.

本文计算了一架模型直升机在＂准悬停＂状态下紊流场的畸变以及相应的干扰噪声谱，并对考虑畸变与非畸变、均匀畸变与非均匀畸变的结果作了比较。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
