势场

The criterion is characterized by briefness and intuition compared with such other performance criteria as manipularity measure.

以此为基础，利用人工势场的理论得到了冗余手臂回避障碍的准则。

We treat the superconductivity electron as Brownian motion particle in period potential, by using matrix continued fraction method. We solve the corresponding Fokker-Planck equation of electron and obtain the Voltage-Current Characteristics of Josephson Junctions with thermal fluctuations.

我们将超导电子视作在其位相形成的周期势场中作布朗运动，并利用矩阵连分法求解相应的Fokker--Planck方程，得到Josephson结在热涨落存在时的Ⅰ-Ⅴ特性曲线，计算结果与实验相符合。

In this paper, harmonic functions were used in defining the potential field.

应用调和函数定义了势场，选取合适的边界条件，解决船舶航行的路径规划问题。

Our research results show that the map can be discontinuous if the potential kicking the particle is discontinuous.

我们的研究表明，若驱动粒子的势场是不连续的，映象模型也可能出现不连续性。

Based on the double integrator model,a control strategy is designed by using potential function which is proposed from the perspective of electric potential.

在二次积分模型的基础上，采用了采用了势能函数进行控制设计，该势能函数是基于电势场的概念提出的。

So it turns out that the Boltzman distribution law is only the first order approximation of the Bose or Fermi distribution. We can say it is the latter that is the general distribution law of ideal gas particle in a potential field.

由此可以证明玻耳兹曼分布规律只是玻色和费米分布规律的一级近似，所以后者才是处在势场中理想气体粒子的一般性的分布规律。

Some people introduce subphotosphere magnetic charges or dipole, which can fit magnetic field on the photosphere, then the separatrix and separator above and on the photosphere can be located, the comparison between their location and location of flare ribbon support the idea of magnetic reconnection. It is called Source Method. Some people extrapolate magnetic fields of photosphere to corona by some method, then use QSLs method to investigate the relations between flare ribbons and magnetic field topology. Some people study relations between flare ribbons and singular point on the plane above photosphere. Some people investigate magnetic topology by analyzing magnetic field of photosphere directly.

或者以观测的光球磁场为基础，来构造光球下的磁荷或磁偶极等光球下磁源，进而研究光球上的磁拓扑结构与耀斑的关系；或者利用各种外推方法将光球磁场进行外推，然后用准分隔层的方法来研究磁拓扑结构与耀斑的关系；或者利用势场模型外推光球磁场，然后研究光球之上平行于光球的某一平面的两维奇点与耀斑的关系；或者直接利用观测的光球矢量场来研究磁场拓扑。

In discussion of this problem,obstacles are supposed having known at numerous methods for predigesting problem.

在该问题的探讨过程中，人们尝试了各种方法，如实时性比较好的人工势场法、虚力场法和全局优化性能较强的遗传算法、神经网络、蚂蚁算法等[1-3]，但是这些方法基本上都是在假设障碍物已知的情形下进行的，即将研究的重点仅放在了算法对最优路径的搜索上。
