With the sample of longitudinal motion equation , calculating hydrodynamic coefficients by the potential fluid theory is introduced 并以其縱向運(yùn)動(dòng)方程為例,詳細(xì)介紹了用勢(shì)流理論求解水動(dòng)力系數(shù)的方法。
The author applies the electric and fluid theory to analysis the results in detail and evaluates the interruption performance of the circuit breaker . furthermore , the calculated results are compared with the test results 在應(yīng)用有關(guān)電器理論、流體動(dòng)力學(xué)等對(duì)其計(jì)算結(jié)果進(jìn)行詳盡分析和解讀的基礎(chǔ)上進(jìn)一步對(duì)該斷路器的開(kāi)斷性能作了綜合評(píng)價(jià),并與試驗(yàn)結(jié)果進(jìn)行了比較。
However , the speed of penetration is equal to predicted value by fluid theory only in c + + plasma with uniform density profile . on other conditions , strong two - dimensional effects , electrostatic accelerating , magnetic pressure and plasma pressure should be included in the fluid analysis 不過(guò),值得注意的是僅有均勻分布的c ~ ( + + )等離子體條件下,磁場(chǎng)滲透速度與簡(jiǎn)化流體理論分析結(jié)果基本相同,而其它條件下的磁場(chǎng)滲透速度均與理論結(jié)果存在一定的差異。
