有限模型

Research on CBR modeling was limited,and there was no suitable model theory to follow.

以往的CBR构模研究非常有限，没有合适的模型理论依托。

The study of the mathematical model for such motion is called celestial mechanics , and involves a finite number of bodies moving under the effects of gravitational attraction given by the Newtonian laws.

对于这种运动的数学模型的研究称作天体力学，包括研究在牛顿万有引力定律作用下的有限个天体的运动。

Then how to use limited Markov chain and Bayes' rule in DHCM to dynamically describe the evolution of enterprises' cooperative relationships, specifically evolution of cooperative relationships building and cooperative relationships selecting is analyzed. Finally, how to optimize related action sets in the model during the evolution is discussed.

模型首先对企业整体协作关系进行了一般性描述和形式化描述，之后利用有限马尔可夫链和贝叶斯法则对在面临新的市场需求的情况下企业之间是否建立协作关系以及建立何种协作关系进行了动态描述，并分析了在新的市场需求下，企业实体将如何选择最优的行动集。

Firstly, the approach formulates a cost functional to turn the inverse problem into a constrained minimization problem according to least squares criterion, then the resulting constrained minimization problem is transformed into an unconstrained minimization problem by using a penalty function technique, and then the closed Fr chet derivatives of the Lagrange function with respect to the properties are derived based on the calculus of variations, finally, one can solve the resulting problem by using any gradient-based algorithm and the finite-difference time-domain method.

该方法首先以最小二乘准则构造目标函数，将逆问题表示为约束最小化问题；接着应用罚函数法转化为无约束最小化问题；然后基于变分计算导出闭式的拉格朗日函数关于特征参数的Fr chet导数；最后借助梯度算法和时域有限差分法迭代反演德拜模型参数。

Since continuum hypothesis is still valid for liquid flow in microchannels with hydraulic diameter at about 100 micro-meters, a turbulence convection heat transfer model for single-phase liquid flow in microchannels is established, in which wall surface roughness viscosity is introduced.
