velocity of the gas meaning in English
气体流速
Examples
- Intense ultraviolet radiation from the core heats the circumstellar gas to ten thousand degrees , and the velocity of the gas flowing away from the star jumps to about a million miles per hour
核心强烈的紫外辐射将星周气体加热到上万度，从恒星流出的气体速度跃升到了每小时百万英里。 - Principal conclusions were drawn as the following : the non compatibility of pressure or velocity of the gas on both sides of the contact surface is the cause of the formation of shock wave ; the heating effect of reflective shock wave to driving gas during charging or exhausting process is the internal mechanism of peak oscillating effect , and all the factors that influence the formation and the running of the shock wave will influence the peak oscillating frequency , cooling effect
主要结论如下：热分离机内激波形成的原因是射气瞬间接触面两侧压力和速度不相容；峰值振荡效应的内在机制为反射激波对充气阶段的驱动气或低温排气的加热，凡是影响激波形成及运动的因素都将对峰值振荡频率、冷效应及热效应产生影响；当充、排气时间比为0 . 1763时，最佳射流激励频率出现在高阶峰值振荡频率上。
