Now the common means of testing the performance of engines in real time is noload dynamometer test , which computes the engine power by measuring the average accelerate time
目前国内外常用的发动机动力性能实时检测系统是采用无负荷测功法，即通过加速后测定平均加速时间的方式来计算发动机的功率值。
On perturation theory resonant cavity model is built by fdtd dividing grids of resonant cavity space and solving them . on the base of the model , electromagnetic fields distribution inside and outside of resonant cavity , also noload resonance frequency and cover material ’ s influences on measurement precision are analyzed
提出了一种基于同轴谐振腔微扰原理的谐振微波传感模型,从谐振腔微扰原理出发,利用时域有限差分法( fdtd )对谐振腔空间进行网格划分并求解,建立了谐振腔传感模型。
