不散射的

The distributed source results from too many multipaths that are induced by reflection, scattering, diffraction and refraction from objects in complex environment and couldn't be described discriminatingly. Thus the source arrives at array antennas in a continual angular extension.

分布源的存在，主要是因为复杂环境下的目标反射、散射、衍射和折射导致大量信号路径存在，而又不可能对每条多径给予描述，从而造成目标空间位置在一定角度范围内连续分布，引起信号到达阵列天线的波前相干损失。

This paper introduces a method of the establishing theory of a-particles scattering,This treatment is given in preference to the more usual one because it does not require a Knowledge of the geometry of the hyperbola.

本文是介绍一种建立α粒子散射理论的方法。这种处理方法比常见的方法为好，因为它不需要几何学的双曲线知识。

One is the theory of perturbation based on the inverse scattering transformation, which is essential method in searching the solution of soliton, so it have important academic meaning, however, the method is not easily understood and grasped because of its complicated line of thinking.

逆散射法是求孤子解的基本方法，这种微扰论有重要的学术意义，但它的思路迂回曲折，不太容易理解和掌握，因此实用上并不十分方便。

A resonance light scattering method for the determination of critical micelle concentration of sodium dodecyl benzene sulfonate was proposed.

利用共振光散射技术在不引入探针的条件下，建立了室温下直接测定十二烷基苯磺酸钠的临界胶束浓度的方法。

Each structure has its own refractive index, and when a light ray crosses an area where the index changes, the light scatters, creating a degree of opaqueness .

每个构造都有各自的折射率，当光线穿越折射率不同的区域时，便会散射而造成某种程度的不透明。

Such local distortions can be viewed asintroducing impurity scattering potential in paramagneticphase,largely increase the resistivity and lower the metal-insulator transitiontemperature Tm.

这样的局域结构畸变在顺磁态可认为是引入不纯散射势，从而大幅地增大了电阻率、降低了金属-绝缘转变温度Tm，并且Tm随σ2的变化关系是线性的。

This is because the fact that, without the anchoring effect of the surface alignment, the cells are always full of unapparent and small focal-conic-like defects; thus no CCLE can be measured due to strong scattering.

因为样品没有表面配向提供的锚定力，样品内充满许多不明显，但是类似focal conic的缺陷，这会造成强烈的散射，也因此无法量测到彩色锥角雷射讯号。

Furthermore, stealth does not merely apply to an aircraft's radar cross section, an aircraft's infrared signature is similarly tailored to be less detectable by the enemy, Davis said.

此外，隐形并不仅仅适用于飞机的雷达散射截面，飞机的红外信号是同样适合不太检出的敌人，戴维斯说。

So, channel fadings can be exploited. But the multi-user diversity gains are limited in two ways. First, there may be a line-of-sight path and little scattering in the environment, and hence the dynamic range of channel fluctuations is too small.

因此，信道衰落是可以利用的，但这种多用户分集受到两方面因素的制约：一是在LOS和非散射信道环境，信道变化范围太小；二是如果信道衰落变化太慢，则不能满足对时延要求严格的应用。

For unexploded ordnances, the four dimensional unexploded ordnance scattering function of slant range, azimuth, frequency and aspect angle is firstly estimated via the SWD. Secondly, the amplitude information of the multi-aspect feature in different frequencies is extracted, and the spatial distribution information of multi-aspect feature in different frequencies is quantitative described using the Hu moment invariants further.

对于未爆物目标，首先利用SWD得到未爆物斜距-方位-频率-方位角四维散射函数估计，然后在提取了不同频率下的多方位特征幅度信息的基础上，利用Hu不变矩进一步定量描述未爆物不同频率下的多方位特征空间分布信息。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
