查询词典 beating engine

Calculating results show that variation of the propellant inlet pressure makes little impact on engine performance parameters, and the engine will transit to a new stable state. The parameter transition curves are smooth. When the engine thrust is adjusted in a small range within a short period, the parameter transition curves are also reposeful. But when the adjusting range becomes large, the parameter transition curves will fluctuate acutely. Thus, when large range adjusting is required, the time of adjusting should be lengthened or the adjusting should be divided into adequate steps.

计算结果表明，当发动机在某一个稳定工况工作时，发动机入口推进剂压强的变化对发动机性能参数的影响不大，发动机的参数都能比较平稳的过渡到一个新的稳定工况；当发动机在短时间内进行小范围的推力调节时，发动机参数的过渡过程的曲线也比较平稳，但是当在短时间内进行大范围推力调节时，参数的过渡过程的曲线振动比较剧烈，因此应当在进行大范围推力调节时，应当对调节时间进行适当延长，或者分级进行推力调节。

Numerical Simulation and Experimental Investigation on A Thermoacoustic Engine with Tapered Resonance Tube A symmetrical standing-wave thermoacoustic engine with tapered resonance tube has been numerically simulated with liner thermoacoustics. The simulation shows that using tapered resonance tube in thermoacoustic engine could decrease the velocity amplitude and lower the total acoustic power loss in the resonance tube. The experimental results indicate that the harmonic was suppressed effectively by using the tapered resonance tube, and the pressure ratio was improved.

采用锥形谐振管的热声发动机的数值模拟和实验研究利用线性热声理论，对一台采用锥形谐振管的驻波型热声发动机进行了数值模拟，发现采用锥形谐振管可有效降低工质气体的速度振幅，进而减小在谐振管中声功率的损失；与一台在相同频率下工作的采用等直径圆柱谐振管的驻波型热声发动机进行了实验对比，结果表明，在使用锥形管作为谐振管的热声发动机系统中，谐振管中的非线性效应得到了明显的抑制，热声发动机在基频模式下稳定运行，压比增大而加热温度降低。

In the condition of definitive structural parameter and part of operative parameter of impulse engine, the effect of controlling force of impulse engine on correct trajectory is analysed. The number of total layer, impulse of each impulse engine and fire interval are determined when the correct ability and flight stability are satisfiable.

在确定了脉冲发动机的结构参数和部分工作参数的情况下，分析了脉冲发动机控制力对修正弹道的影响能力，确定了在满足修正能力及飞行稳定性的条件下脉冲发动机的总层数、单冲和点火间隔。

This engine was safer than Savery's engine because it didn't use high pressure steam--the piston is brought up by the beam and not by steam pressure. And, by making the cylinder larger, the power of the engine could be increased considerably.

这种蒸汽发动机比萨韦里的安全，因为它不采用高压蒸汽——活塞是由吊杆而不是由蒸汽带动的，并且，只要加大圆筒，发动机的功率就能大大增加。

Car flooded the water will enter the engine from the inlet resulting in engine flameout this time there will be water accumulation in the cylinder chamber and spark plugs in braving the water if the owner starts the engine the piston will Top connecting rod bend or even cylinder head roof leak causing irreparable damage.

车被淹后，水就会从进气道进入发动机，从而导致发动机熄火，这时候就会有水吞积在汽缸室，而火花塞在顶着水的情况下，如果车主启动发动机，就会把活塞连杆顶弯，甚至将缸盖顶漏，造成安全阀不可挽回的损失。
