To analysis combustor structure ’ s contribution to fluxion and combustion explicitly , it is necessary to study the impaction of wave system and fire temperature on chemical reaction and heat release ’ s procedure 为了细致分析燃烧室结构和流动进口参数对超燃的作用关系,必须细化研究超音速流场的波系结构和燃气温度对化学反应放热过程的影响。
A new standpoint produced from the study is that the guided wave system in the oil well is different from the normal circular wave guide , as the fluid is a conductive medium , and it allows the higher or lower frequency waves to propagate 通过研究提出了由于井内流体为有耗媒质,油井构成的导波系统不同于一般的圆波导,可以传播高频或低频电磁波的新观点。
In the microwave and milli - wave system , the performance of the up - mixers play a key role in the whole system . this dissetation make a research in the theoretics and design of the milli - wave up - mixers and the lo multipliers 在微波、毫米波系统中,性能优越的上变频组件对系统性能起着关键性的作用。本文对毫米波上变频器及其本振倍频链的理论和设计进行了研究。
Wave systems are analyzed from predicted flow parameters . combustion state is evaluated from the distribution of chemical component density . therefore , theoretical explanation is afforded to improve and optimize chamber frame 采用预测的流动参数分布云图分析了波系结构,从化学组分的浓度分布判断燃烧状况的好坏,从而为改善优化燃烧室结构提供理论依据。
Today , millimeter - wave systems are expected to be more and more compact and light , so reduction of both dimensions and weight of the circuits is facing challenges . meanwhile , the need of systems ’ integration is more and more imperious 在毫米波系统日益追求小型化、轻量化的今天,毫米波电路的体积、重量面临着新的挑战,毫米波系统全集成化的要求也日益迫切。
