常見(jiàn)例句The longitudinal wave cannot exist near the surface of a solid, and those exist near it are gliding irrotational waves. 縱波不能在固體表面存在,在固體表面存在的是相應(yīng)的滑行集散波。The liquid is assumed to be ideal and incompressible, and the motion is provided as irrotational. 計(jì)算采用了理想不可壓縮勢(shì)流模型,該模型能夠同時(shí)考慮重力和表面張力的影響。Kinematics Modeling and Simulation of Irrotational Displacement Isolator with Two DOF[J]. 引用該論文 LIANG Shuang;AN Zhi-yong;YU Qiu-shui.Under the assumption of incompressible, inviscid, and irrotational flow, the governing equation and boundary conditions are formulated. 本文基于不可壓縮、無(wú)粘性、無(wú)旋流動(dòng)假設(shè),首先給出描述機(jī)翼非定常運(yùn)動(dòng)產(chǎn)生擾動(dòng)流場(chǎng)的控制方程和邊界條件。This clearly indicates that uniqueness is reached provided that the irrotational and equivoluminal wave velocities, ??and ??are real and nonzero. 這就清楚地表明,如果無(wú)旋波速度?禿偷忍寤?波速度?問(wèn)遣壞扔諏愕氖盜浚0則唯一性是成立的。Based on irrotational flow hypothesis and linearized free surface boundary condition,the similarity law of liquid sloshing with small amplitude is studied in this paper. 在理想流假設(shè)及線(xiàn)性化的自由表面邊界條件的基礎(chǔ)上,對(duì)剛性容器中液體小幅晃動(dòng)進(jìn)行了流體相似律的研究。 返回 irrotational
