给出了一个计算980 nm泵浦激光二极管与柱形透镜光纤耦合角向容忍度的理论模型，并选择圆形的柱透镜光纤进行数值计算，得出了在水平和垂直方向上偏转加平移时的相对耦合效率及绕光纤轴向转动的相对耦合效率的数值计算结果并加以分析，同时也研究了光纤透镜的形状和激光二极管与光纤的间距对相对耦合效率的影响。

In this paper, the modeling theory of multi-rigid-body dynamics was thoroughly investigated in order to make up the shortcoming in the above modeling method. The major research achievements are as follows:①Based on the matrix of direction cosine between the body-fixed base and the reference base, and Poisson equation of a rigid body rotating, the coordinate transformation method for the modeling of treelike multi-rigid-body dynamics is derived. The method is very routinization and easy to use the computer to carry on the symbol derivation.

本文针对上述建模方法存在的不足，深入地研究了多刚体系统动力学的建模方法，并将所研究的新方法应用于惯性振动设备的建模，取得的主要研究成果如下：①基于刚体连体基关于参考基的方向余弦矩阵和刚体转动的Poisson方程，导出了建立树形多刚体系统动力学方程的坐标变换法，其过程极其程式化，便于利用计算机进行符号推导。

Bells rang, the wheel began to churn, and Banneker, falling asleep in his berth 睡床 with a vivifying breeze blowing across him, awoke in broad daylight to a view of sparkling 闪烁的 little waves which danced across his vision to smack 拍打 impudently 无礼 the flanks 侧面/腹 of the speeding craft.

铃声响起，舵轮开始转动，而班纳克，在他的睡床上睡着了，生动的微风吹在他身上。在大白天他醒来，闪闪发光的小浪蹦蹦跳跳——进入他的眼帘——放肆地拍打着快速行驶的游艇的船舷。

Dairyman Crick and his wife, the milkmaids Tess, Marian, Retty Priddle, Izz Huett, and the married ones from the cottages; also Mr Clare, Jonathan Kail, old Deborah, and the rest, stood gazing hopelessly at the churn; and the boy who kept the horse going outside put on moon-like eyes to show his sense of the situation.

奶牛场老板克里克和他的太太，住在场内的挤奶姑娘苔丝、玛丽安、莱蒂·普里德尔、伊茨·体特，住在场外茅屋里的结了婚的女工，还有克莱尔先生、约纳森·凯尔、老德波娜以及其他的人，都站在那儿瞪着搅黄油的机器，谁也没有办法；在外面赶马使机器转动的小伙子眼睛瞪得大大的，对这件事情表现得很关心。

Therefore, the needlepoint of phonograph gradually slides along the surface of the rotating microgroove, bringing to listeners not only a way of reminiscence, but also the originality of hearing, an irresistible glamour.

因此，当黑胶唱机的唱针缓缓滑过密纹转动的唱片，带给听者的，不仅仅是怀旧的情绪，更多是来自听觉本身的原汁原味，散发着让人无法拒绝的魅力。

Her main scientific interests are comparative planetary interiors and rotation, as well as modeling tides and nutation of the Earth, Mars, Mercury and Venus.

她的主要研究专长在于各行星的内部结构和自转的比较。亦精于地球、火星、水星和金星的潮汐作用和地轴的转动的计算。

Motion synchronization between tool in X direction and principal axis rotation was controlled by electronic gearbox in cam turning. And profiling mechanism could be superseded by servo tool-holder. Linear motor direct drive servo tool-holder was designed, and host-slave control system with PC and DSP was developed for the require of high-speed and realtime servo. The technical process was analyzed in cam turning. Servo tool holder with tool swinging and principal axis variable rotate speed were presented to keep constant cutting angle and speed.
