For TEM model in coaxial resonant cavity, the influence of shape and position of inner conductor on electromagnetic field, start-up and steady work was studied.
对TEM模，分析了内导体形状、位置对谐振腔内电磁场分布的影响；以及它们对启动和稳定工作的影响。

One and a half stages of a subsonic compressor were simulated with steady and unsteady calculation, comparing the performance with different combination of tip leakage and seal cavity.
The measurement of the total emissivity of a solid surface in the black cavity which is immersed in liquid nitrogen and under high vacuum (10-6 torr) by steady caloric method is described.
