自由空间

While the Internet provides a space the humanbeing never had before,it also results in absolution liberalism and anarchism.

互联网在给予人类从未有过的自由空间的同时，也导致了绝对自由主义和无政府主义的出现。

Since the attenuation of the free-space channel between ground and satellite is contributed by the aerosphere, its equivalent length is about 5 km and the total attenuation of round-trip is equivalent to 10 km free-space channel in the earth surface aerosphere.

由于地面-卫星之间的自由空间信道的衰减主要集中在地面大气层，其等效厚度约为5km，往返两次的信道衰减等效于地面大气层的10km。

Based on latest CISPR 16-1-4, a new evaluate method for anechoic chamber, SVSWR is introduced.

根据最新的CISPR 16-1-4标准，介绍了一种用于取代传统1GHz～18GHz自由空间传输损耗新的电波暗室评估方法，即场地驻波比测试法。

Around to keep its free space contiguous so there is enough room for new allocation.

围绕保持连续的自由空间，以便有新的分配足够的空间。

Different from free space, a microcavity laser has dimensions on the order of the emitted wavelength, so the spacing and spectra distributions of EM modes can't be described by a smoothly continuous distribution function.

一个微腔激光器，其谐振腔至少有一维的尺寸可与其发射的波长相比拟，与自由空间不同，因而电磁模的空间和光谱分布再不能用平滑连续分布函数来描写。

The dissertation presents a number of methods and theory involving in diffraction integral, Fourier transform, directly solving differential wave equation, vector analysis, which can be used to study ultrashort pulsed beams propagating in free space, linear dispersive

现将本论文所得主要结论总结如下：基于瑞利—索末菲衍射积分、角谱法和复解析信号法，推导出了等束腰宽度超短脉冲高斯光束在自由空间的严格的传输方程和傅里叶谱，适用于几个光周期甚至一个光周期以下的超短脉冲光束和大衍射角情形，而不产生空间奇异

Based on the Rayleigh-Sommerfeld diffraction integral and complex analytical signal representation,the free-space propagation equation and its Fourier spectrum for ultrashort chirped pulsed Gaussian beams are derived,and the far-field analytical electric field and spatial intensity are presented.

基于瑞利-索末菲衍射积分，使用复解析信号法推导出了啁啾脉冲高斯光束在自由空间中的传输方程及其傅里叶谱，给出了远场的光场和空间光强的解析式，研究了啁啾参数C对脉冲光束传输的影响。

A friction compensation algorithm based on the feed-forward and fuzzy theory is implemented after analyzing the friction characteristic of HIT-1 dextrous robot hand.

在基于指尖力的阻抗控制中，定性分析了摩擦力对自由空间中的位置跟踪和约束空间中的力控制的影响，并结合HIT-1机器人灵巧手摩擦力的具体特点，提出了前馈加模糊的摩擦力补偿方法。

In the basis of comparing the developing projects on the optical interconnection networks, combining with the actual probability of realization, we proposed the scheme of free space optical crossbar interconnection network using spatial light modulator . This interconnect structure is the most powerful single level interconnect network with the characteristics of reconfiguration and non-blocking. It can achieve arbitrary point-to-point link. Even more has it the ability of broadcasting and funnelling.

在比较现有的光互连方案的基础上，结合具体的可实现性，本文提出了使用空间光调制器的自由空间光学交叉开关互连网络的方案，这种互连结构是功能最强的单级互连网络，具有可重构性和非阻塞性，不仅能实现任意点到点的连接，还具有广播和汇集的能力。

This gets the kitchen working space into the corner, thus giving a lot of free space to move about.

能从厨房工作空间的一个角落，从而使大量的自由空间走动。

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。
