compressibility speed 中文意思是什麼

compressibility speed 解釋
壓縮流速度
  • compressibility : n. 壓縮性；壓縮系數；壓縮率。
  • speed : n 1 快，迅速。2 速率，速度。3 （汽車的）變速器，排擋。4 （膠片，照相紙）感光速度。5 〈古語〉興隆...
  1. Compressibility effects are investigated with highspeed models in high-speed tunnels.

    壓縮性影響需用高速模型在高速風洞中試驗。
  2. But it is gas medium with compressibility and low viscosity that leads to low natural frequency, small damping ratio, low positional precision and rigidity, bad low speed characteristics, which limit the application of pneumatic servo technique

    但因為氣體的可壓縮性和低粘性，導致氣壓伺服系統固有頻率低、阻尼比小、定位精度和定位剛度低、低速性能差，使得氣壓伺服技術的應用受到限制。
  3. Based on pseudo compressibility, two - dimensional low - speed flows are numerically simulated by solving euler and navier - stokes equations. the pseudo - compressibility term is introduced to the continuity equation of incompressible governing equations, which results in a closed hyperbolic system of equations

    通過在不可壓連續性方程中引入擬壓縮項，使控制方程成為一個封閉且可以沿時間方向推進求解的雙曲型偏微分方程組。
  4. The results show that the existing of the fluid phase has great influence on the propagation of rayleigh waves. when compressibility of the solid grains are considered, the speed of rayleigh waves is not only decided by the speed of the fast wave and the quasi - transverse wave in the solid skeleton, but also affected by the speed of the slow wave

    指出橫觀各向同性含液飽和多孔介質中，流體相的存在對瑞利波的傳播特性有很大影響，當考慮固體顆粒的可壓縮性時，瑞利波的波速不僅取決于固體骨架中快波和剪切波的波速，而且受慢波波速的影響。
  5. 3. unsteady incompressible euler and navier - stokes equations are solved for two dimensional low - speed flows by the method of pseudo compressibility

    推導了擬壓縮方法二維非定常不可壓euler n - s方程，編寫了二維非定常euler n - s方程計算程序。
