势流

Because of the viscosity of fluid and non-existence of velocity potential, the symmetry of mass matrix, stiffness matrix and the coefficient matrix of the first order of system no longer exists, so the modal analysis of system becomes very complicated.

由于流体粘性的影响，流场有旋，没有速度势，所以系统质量阵、刚度阵以及一阶项的系数矩阵的对称性被破坏，从而使得系统的模态分析变得很复杂。

During different periods of Dan, there was great water vapor change as indicated by stream function, velocity potential and vapor budget, which showed the importance of water vapor in the development of typhoon Dan.

在Dan发生发展的不同时期，由大尺度水汽通量流函数和速度势表示的水汽通量输送和辐合也有明显的变化，表明水汽输送和辐合在Dan的发生发展及消亡过程中有一定作用。

With the guard terminal at the same potential, the leakage current through the switch is minimized.

由于保护端子处于相同的电势，所以通过开关的漏流将最小。

The fluid domain was divided into two regions by imaginary interface. The velocity potential in each region was expanded by eigenfunctions.

假想存在一个圆柱面，把流场划分为内外区域，在每个区域上将速度势用特征函数展开，然后在它们的公共边界上进行街接。

AIM: To study the mechanism and implementation of current pulse exciting impedance measurement of bio tissues.

为减少皮肤电极接触阻抗、极化电势所引起的伪差，实际应用中多采用正弦波恒流源激励［2］。

Energy in , obtain the chemical potential of the superflow state.

通过最小化中的能量，获得超流态的化学势。

The innovative and unique points are as follows. The method of magnetic potential self-balance is put forward applying the characteristic of iron core''s rectangular magnetization curve. The different of ampere-turn is measured by the reasonable design of reactor''s iron core. The feedback compensation system is a closed loop without high gain.

其创新、独特之处在于提出了利用铁芯矩形磁化曲线的特性，建立起直流磁势平衡的思想方法，并通过对电抗器铁芯结构的合理设计，巧妙地实现安匝差检测，构成差流回馈补偿系统，而不是高增益的闭环系统。
