查询词典 scatterer

Small aspect change will lead to a big change of the complex amplitude, since, although the variation of the range of each scatterer to radar is very small, it is still large enough compared to the small wavelength and may cause a big phase change.

当视角有微小变化时，虽然各散射点到雷达的距离变化并不大，但相对于微波波长，其相位差的变化相当大，从而使各分辨单元到复振幅有大的起伏，即一维距离像的方向敏感性十分敏感。

Taking into account the influences of scatterer geometrical shapes on induced currents, an algorithm, termed the sparse-matrix method, is proposed to calculate radar cross section of aircraft configuration.

论证了散射体几何形状对感应电流的影响规律，并基于飞行器几何外形特征和矩量法，提出了一种用于飞行器雷达散射截面计算的高精度快速算法。

Optical clearing is a technique to increase the light penetration depth in the tissue by the application of clearing agent to reduce light scattering and match the refractive index between the scatterer and the environment.

光透明技术是一种在生物组织中通过施加光透明剂来抑制光散射，改善散射体和环境的折射率匹配，从而增加光在生物组织中的穿透深度的技术。

Aquatic or marsh-growing fern allies; known to have existed since the Cenozoic; sometimes included in Lycopodiales.

生活于水中或湿地的蕨类；从新生代生存至今；有时归于石松目之中。

The engine was uprated from a 90hp Franklin to a 125hp Lycoming.

改良过的引擎是从90hp到125hp莱康明富兰克林。
