间距

By adjusting the positions and angles of the two DVD optical pick-up heads, the relative distance of the two laser spots can be equivalent to one quarter of the grating pitch. When the grating moves, the surface profile of the grating can be measure directly, in order to obtain the two quadrature sinusoidal signals. Then by counting the zero crossing of these two quadrature sinusoidal signals and calculating the interpolation value of these two quadrature sinusoidal signals, the moving direction and moving displacement value of the grating can be obtained.

采用两个光学读取头，且两个光学读取头共用同一分光镜与同一聚焦物镜，於搭配光路的设计，可使两个光学读取头之光束打入同一聚焦物镜，藉由调整两个DVD光学读取头的位置与角度，使聚焦物镜聚焦的两相近聚焦光点的距离相等於四分之ㄧ光栅尺间距，当光栅尺移动时，可直接量测光栅尺的表面轮廓变化，以获得一组正交的弦波讯号，继而利用讯号四分割与细分割处理，计算出光栅尺之移动方向与移动量。

The last one is to change a YBCO bulk into a superconducting quasi-permanent magnet, levitation force of a YBCO bulk with 40 mm in diameter is up to 218.3N at 5mm gap over a NdFeB guideway at 77K by this method.

The invention relates to an electric machine (10) which can be operated as a motor or a generator. Said machine comprises a rotor (26a, 26b) rotatably mounted in a housing (12), a rotor shaft (24) which extends beyond the housing (12) and a plurality of electromagnet components (28) that are statically arranged in the housing at a distance from the axis of rotation of the rotor in evenly distributed angular distances. Said electromagnet components have each a wire-wound coil (30) consisting of a coil core (32) which carries one or more conductors.

本发明涉及一种可作为电动机或发电机工作的电机(10)，它包括一个可旋转地安装在外壳(12)内带一根伸出外壳(12)的转子轴(24)的转子(26a、26b)，以及包括多个离转子旋转轴线一定距离处按均匀的角向间距位置固定地布置在外壳内并各有一个支承着由一根或多根导线组成的线圈绕组(30)的线圈芯(32)的电磁构件(28)。

Resonance frequency, resonance amplitude and radiation pressure are related to the distance between the two bubbles.

共振频率，共振振幅及声压与两气泡之间的间距有关。

Upper/lower segments ratio 1.1:1, arm span 108 cm.

上下部量比例为1.1：1，手臂伸展间距108cm。

On the other hand, a deep-rooted, low-tillering variety has a well-spaced, lateral root distribution and its roots grow more actively in deep soils than those of a shallow-rooted, high-tillering variety.

另一方面，深根、低分蘖品种根系分布间距适当、侧向生长、深层土壤中的根系比浅根、高分蘖品种活力更强。

Between the chain and ring spacing are like a well-calculated and carefully processed.

连环与环之间的间距都像是有着周密计算和精心加工的。

At the same time, the finite staff element method is used to analyze the influence of beam rigidity; and the two new methods proposed are used to analyze the influence of connect way between piles and beam; and the conclusion is obtained that the rigidity ratio between beam and piles being 0.48 is appropriate; the continuative increase of the rigidity ratio is not significant; the worst condition is that connecting way between piles and beam is hinged; the best condition is that connecting way between piles and beam is rigid. Whether is single-row pile or are double-row piles, when the front of single-row pile or the front of the front-row pile(in the double-row piles) needed excavation, it is supposed to that ought to be carefulness to excavate, because it is that the engineering cost increased greatly.

同时，用有限杆单元法，对双排桩的连梁刚度和用文中提出的方法以桩梁连接方式进行了试验和理论分析得出如下结论：在满足不相互影响排桩间距的情况下，桩顶连梁与桩的刚度比不小于0.48是合适的，此时再增加连梁刚度无意义；桩梁连接为铰结时双排桩受力变形性质最差，刚结时受力变形性质最好；不论是单排桩还是双排桩，桩前和前排桩桩前土体需要开挖时应慎重，因为这种开挖对支护结构影响很大，造价增加很多；双排桩省钱，而且抵抗变形的能力强，值得在工程中研究和广泛应用

The highest voltage that a relay can switch reliably under given conditions is usually determined by the spacing between contacts and the dielectric strength of the gas inside the relay.

继电器在给定条件下能够可靠切换的最高电压通常是由继电器内部触点之间的间距和气隙的介电强度决定的。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
