This invention relates to a slider (11) for an optical data writing/reading apparatus (1), the slider carrying an optical lens (40) defining a focal point (42), the slider having a configuration such that, upon variation of the disk speed such as, for example, caused by a slider movement from an inner diameter to an outer diameter, the pitch angle varies owing to a pivot movement about a pivot axis which lies in a vertical plane through the focal point, the pivot axis preferably coinciding with the focal point.

本发明涉及用于光学数据写/读装置(1)的滑动器(11)，在该滑动器(11)上装有确定焦点(42)的光学透镜(40)，该滑动器具有这样一种结构，以便于在诸如滑动器从内径到外径运动造成盘速变化时，由于围绕位于经过焦点的垂直平面内的旋转轴的枢轴运动而改变倾斜角。

The refraction, reflection and propagation of the acoustic wave in a rod are studied quantitatively when a line-focused probe is employed in an axial scanning in immersion testing. The shape and position of the first and second focal line of the probe in the cylinder are calculated.

定量研究了采用线聚焦探头、液浸法、轴向扫描探伤时，棒材中声波的折射、反射和传播规律，计算得到了工件中的一次焦线和二次焦线的形状和位置。

The assembly method of the invention has the main principles that a semiconductor laser, an optical coupled apparatus and a fiber head are orderly arranged, and the optical axes of the semiconductor laser, the optical coupled apparatus and the fiber head are arranged in a same straight line; the focal plane of an output beam which is focused on the fiber head is changed through utilizing and adjusting an adjusting device which can cause a beam to deviate; the sensitivity of the assembly adjustment of the adjusting device in the course of fixing is reduced.

本发明的方法的主要原理是将半导体激光器、光学耦合器件、光纤头依次排列，并使它们光轴在同一直线上，然后通过利用一使光束发生偏移的调节器件，通过调节该调节改变聚焦于光纤头的输出光束的焦平面，降低调节器件装配调节的固定时的敏感性。

TURN: The shoulders and hips pivot and the right foot turns toward the net post as you transfer your weight to it. The forearm is parallel to the ground. The racket head angle with the forearm remains the same.

转体：肩髋以身体中心线为轴转动，以右脚取位，当重心移至右脚时右脚应朝向同侧网柱，持拍手前臂平行地面，拍头和前臂间角度保持不变。

The gearbox has three wet multi-disc friction clutches, and during gear shifting, the clutch discs are pressed by the oil pressure-driven piston acting along the shaft.

Because of the three-throw crankshaft structure particularity,this kinds of technics furnishment can't satisfy the production need.

卧式车床加工轴类零件时，常采用卡盘和顶尖来夹紧、定位，但是由于三拐曲轴结构的特殊性，这种装夹已不能满足生产的需要。

Today, at the time of the strategy for the grand-scale being implemented, this paper primarily tests the relationship between Continental Bridge transportation and its economy through quantitative analysis, which can proof the dependability and feasibility of the "point-line" development theory.

当前，在西部大开发深入展开之际，本文从定量的角度验证陆桥运输的经济作用，检验西部大开发的"点——轴开发模式"经济理论的可靠性和可行性，为各级政府和企业的经济决策提供数量化建议，更有利于为交通部门及经贸部门在做具体决策、预测时提供数量化方面的依据。

This happens because the speed of gravitational fall is independent of mass and the hammer goes into free flight as soon as the knuckle leaves the jack.

原因是，自然落下的速度跟质量是无关的，当弦槌下的滚轴离开顶槌器时，在击弦前最后的几个厘米，弦槌是呈自由飞行状态的。

If not, the bearings will be worn and the life will be shortened, The methods of maintenance are as follows: oiling once for each shift. It should be noticed that the oil channel must be cleaned immediately if the oil is not be consumed or the loss is slow then 50# motor oil should be added. The oil cup is placed on the upper end of principal axis. Each shift should add 3# lithium base grease once with grease gun on bearing of principal axis base and bearing of milling roller. Disconnect and clean the analyzer once for 6 months and apply 3# lithium base grease. Apply lithium base grease for bearing room.(see lubrication system for details).

保养方法如下：主轴加油时间每班一次，但必须注意，发现油杯的油没有损耗或损耗太慢时，应立即清洗油道，再加50#机械油，油杯位置在主轴上端，主轴底座轴承，磨辊轴轴承每一班用黄油枪加注3#锂基润滑脂一次，分析器轴承每六个月拆开清洗一次，加足3#锂基润滑油，风机轴承室加锂基润滑脂。
