阵元间频率增量按对数增加，发射波束不再按距离周期性出现，发射波束图最大值只有一个。相较于阵元间频率增量固定的传统频率分集阵列，log-FDA能够抗距离相关的干扰，而且发射能量不泄露，具有一定的低截获性能。(FDA with logarithmically increasing frequency offset to achieve a beampattern with a single maximum at the target location. FDA radar with uniform interelement frequency offset, its beampattern exhibits maxima at multiple range values. doe tu the multiple maxima, a number of reflectors located at any of the maxima can interfere the target-return, thus deteriorating SINR.)

直流输电比起交流输电更适合进行远距离高压输电，基于PSCAD电磁暂态仿真软件构建了交流系统、换流变圧器、换流器、交-直流滤波器、平波电抗器及直流输电线路等的仿真模型，并以此搭建了500kV高压直流输电系统仿真模型，验证了该模型的准确性。(DC transmission is more suitable for long-distance transmission than AC transmission, the electromagnetic transient simulation software PSCAD is built based on the simulation model of AC system, converter transformer, voltage converter, AC / DC filter, smoothing reactor and DC transmission lines, and to build a 500kV HVDC system simulation model validation the accuracy of the model.)
