Polarimetric Synthetic Aperture Radar measures the frequency, magnitude, absolute and relative phase of targets' backscattering signals in imaging scene for any possible combination of transmit and receive antennas. The polarization synthesis technique on one hand has greatly increased the acquired polarization information, on the other hand increased the difficulty of system design and signal processing.

中文摘要极化合成孔径雷达的回波信号可以提供不同收发极化状态组合下成像场景内目标散射波的幅度、绝对和相对相位、频率等信息，极化合成技术的出现使获取的信息量成倍增加，信息量增加的同时系统设计和信号处理的复杂度增加，因此极化合成孔径雷达相关技术的研究成为微波遥感领域的热点。

Main factor determining the characteristics of a loading vehicle is its dynamometer characteristics. Currently common dynamometers couldn't meet the low speed and high load requirements of a loading vehicle and make the power absorbing system structure complicated and the test procedure complex.

决定负荷车特性的主要因素是测功机特性，目前常见的测功机不能满足负荷车低速大负荷加载要求，并使负荷车功率吸收系统结构复杂，试验操作繁琐。

For example, current highlevel programming languages and integrated development environments provide abstractions that shield developers from intricate lower-level details and offer automated support for transforming abstract representations of source code into faithful machineexecutable forms.

例如，当前的高层次的编程语言和集成开发环境提供抽象，从复杂的低级别的细节屏蔽开发和转化提供自动化支持抽象源代码表示将忠实machineexecutable 形式。

In higher levels, structures look more complex, and abstract, and several aspects of the game speed up.

在更高层次，结构更复杂，抽象的，有几个方面的游戏加快。
