frictional dissipation 摩擦耗散(8)   摩擦耗散      Using Serrin-Joseph's energy method and variational principle, the nonlinear barotropic stability criteria of the basic flow with the total energy and total potential enstrophy was found from a nonlinear quasi-geostrophic barotropic equa-tion embedded with frictional dissipation, thermal driving and large topography used by Charney in his investigation of the multiple flow equilibria.      本文从Charney研究多平衡态的包含摩擦耗散、热力强迫和大地形的非线性准地转正压涡度方程出发,应用Serrin-Joseph的能量方法,利用变分原理,分别用总能景和总位涡拟能导得纬向基流的非线性正压稳定性判据。 短句来源      From a nonlinear quasi-geostrophic equation set including f rictional dissipation and a nonlinear shallow water equation including frictional dissipation and large topography, using Serrin-Joseph's energy method, by means of the variational principle, the nonlinear stability criterions of the shearing basic flows both above two equation sets with the total energy and total enstrophy respectively are found.      本文从包含摩擦耗散的非线性准地转方程组和包含摩擦耗散与大地形作用的非线性浅水波方程组出发,使用了Serrin-Joseph的能量方法,利用变分原理,分别用总能量和总位涡拟能导得这两个方程组的切变基流的非线性稳定性判据。 短句来源      Starting from nonlinear equations on the F-plane containing frictional dissipation under the Boussinesq approximation, a new kind of generalized energy is proposed as the Lyapunov function, and averages are taken as any functions of (x, z) instead of the commonly-used means of bilinear functions of (x, z), thereby resulting in a new criterion of generalized nonlinear symmetric stability.      从含摩擦耗散的f平面上Boussinesq近似下的非线性方程组出发,提出了一种新的广义能量作为Lyapunov函数,取消平均量是(x,z)的双线性函数的限制,并取平均量是(x,z)的任意函数,由此导出了一种新的广义非线性对称稳定性判据。 短句来源      ON THE FRICTIONAL DISSIPATION DUE TO THE BOUNDARY OF A CYLINDRICAL VESSEL      圆柱空间的边界摩擦耗散 短句来源      ON THE NONLINEAR STABILITY OF SHEARING BASIC FLOW IN THE FRICTIONAL DISSIPATION ATMOSPHERE      摩擦耗散大气中切变流的非线性稳定性 短句来源 更多          “frictional dissipation”译为未确定词的双语例句      However, after the typhoon interacted with the westerlies, the KE generation by baroclinic process increased and the frictional dissipation played a significant role in this stage.      台风与西风带系统相互作用后的动能平衡与温带气旋类似。 斜压过程的动能产生率增加,摩擦在台风衰减过程中起重要作用。 短句来源      From a nonlinear quas i-geostrophic barotropic vorticity equation including frictional dissipation, using Serrin-Joseph's energy method, by means of the variational principle, we found the nonlinear barotropic stability crite-rions of the zonal basic flow with the total energy and total enstrophy the linear combination of above two quantities respectively.      本文从含Ekman摩擦的非线性正压涡度方程出发,应用Serrin—Joseph的能量方法,按变分原理,分别用总能量、总涡度拟能和两者的线性组合导得纬向基流的非线性正压不稳定判据。 短句来源      From a two-level nonlinear baroclinic model including frictional dissipation, using Serrin-Joseph's energy method, by means of the variational principle, the nonlinear baroclinic stability criterions of nonzonal flows with the total energy, and total enstrophy, the linear combination of above two quantities respectively are found, and these criterions are compared with the linear stability criterion.      本文从含Ekman摩擦的非线性两层斜压模式出发,应用Serrin-Joseph的能量方法,按变分原理,分别用扰动总能量、总位涡拟能和两者的线性组合导得了非纬向基流的非线性斜压稳定性判据。 并和线性判据作了比较。 短句来源      two-dimensional semigeostrophic frontogenesis model is used to study the influence of the condensation heating and frictional dissipation on frontogenesis circulation.      本文在二维半地转峰生模式中，考虑了水汽凝结加热和边界层抽吸作用对锋生及越锋环流的影响。 短句来源      While strenghtening constantly with engine, it is comparatively common that the frictional dissipation causes destroy of fatigue and makes invalid problem on the connecting rod bearing.      随着内燃机的不断强化,摩擦损耗导致疲劳破坏而使内燃机连杆轴承失效的问题较为常见。 短句来源   相似匹配句对      ON THE FRICTIONAL DISSIPATION DUE TO THE BOUNDARY OF A CYLINDRICAL VESSEL      圆柱空间的边界摩擦耗散 短句来源      Dynamic Analysis of Frame Structure with Frictional Energy Dissipation      摩擦耗能框架结构的动力分析 短句来源      Frictional Vibration      摩擦振动(一) 短句来源      dissipation of wave energy;

Kinetic energy(KE)budget and available potential energy (APE) were computed by using the quasi-Lagrangian scheme during the period 10 to 12 Aug. 1976.
