摘　　要：为了进一步掌握气动谐振加热的规律,为气动谐振点火器的研制提供试验基础,在原有气动谐振加热初步试验研究的基础上对谐振气体流量变化,不同的排气孔形式以及不同内径的谐振腔对谐振加热性能的影响进行了研究。通过大量的气动谐振加热基础试验,得到了谐振加热性能随不同参数变化的规律,为气动谐振点火器结构参数的选择提供了试验基础。In order to learn more gas-dynamic resonance heating rules and to provide experimental foundation for investigating gas-dynamic resonance igniter, gas-dynamic resonance heating experiments based upon initial tests were carried out. Factors investigated, which affect resonance heating characteristics, include variation of flow rate, different structures of exhaust hole and different diameters of connect cavity. Through lots of experiments with different design parameters, some gas-dynamic resonance heating rules were found, and optimum structure design parameters were obtained for gas-dynamic resonance igniter design.
