In addition to measurements of conventional dynamic parameters o n a model surface,an optical observation method was employed,which directly reco rded self-luminosity of high temperature gas induced by a two-dimensional mode l in high enthalpy flow and combustion radiation.Hypersonic flow fields passing over a sharp strut including fuel injection were displayed and recorded with a high-speed CCD camera.A phenomenon of supersonic diffusive combustion under fre e boundary condition was observed.

实验除测量常规流场参数和模型表面的动态参数外，主要使用二维实验模型，利用高温气体的自发光和燃烧伴随的发光现象，采用高速摄影技术来观测燃烧现象，记录到高焓流场中叠加燃料喷射和燃烧的流场，观察到自由边界条件下扩散控制的超声速燃烧现象。

The fre-quency equations are derived according to stress match, consid-ering gear as a thin bar and adopting exponential horn. Then the influences of vibration of transformer which consists of horn and gear are explored, which come from the length of horn and the machining frequency. It has been discovered that the reso-nance frequency of the horn is the detune one of transformer and the resonance frequency is not same as one of horn, which provide theoretical rules for transformer design.

鉴于此，根据应力耦合，将齿轮作为圆盘，采用指数型变幅杆，推导频率方程，对变幅杆的设计长度和变幅器振动频率进行数值分析，发现变幅杆的共振频率恰好是变幅器的失谐频率，变幅器的共振频率与变幅杆的固有频率也不相同，这能够为超声珩齿变幅器的设计提供理论依据。

The conclusion was drawn that the tetrazine ring and amino group in the DAAT structure were in a plane and were able to build a conjugated π-bond, the calculated fre-quency and intensity were consistent with the experimental values in IR spectra, all thermal energy, thermal capacity and entropy would increase with the increase of temperature.

结果表明： DAAT分子结构中偶氮基两侧的四嗪环和氨基基本在同一个平面上，形成一个大的共轭π键；红外谱计算频率和强度与实验结果整体吻合较好；热能、热容和熵均随温度的升高而增大。
