有限函数

A new solution has been obtained for Larson′s model of finite pulse time effects in the flash method for measuring thermal diffusivity by means of Green′s functions.

用格林函数法推导了闪光法测定热扩散率的有限脉冲效应的Larson方程得到了一个与Larson不同的解，对这2个解进行了对比和讨论，指出了Larson的解所存在的问题。

We have made use of the spectral of effective gluons in static limit, calculated the effective thermodynamic potential in QGP with a soft exchange gluon at two-loop level, and studied the influence from the transverse gluon width to the potential.

我们先采用静极限下有效胶子的谱函数，通过计算含单个软交换胶子的QGP系统的热力学势直到两圈，研究了横胶子的有限宽度对系统热力学势的影响。

The effects of hot/dense hadronic environment on the spectral function of p meson is analyzed. It is found that hot/dense environment plays an important role to the spectral function: when the temperature or the density is not too high.

本文基于虚时形式的有限温度场论，分析了热密强作用物质环境对ρ介子性质的影响，计算得到了ρ介子的谱函数。

Wideangle parabolic approximations to wave equation usually lead to nonconstant differential migrators with their coefficients varying with lateral velocity variations, and hence require a finitedifference numerical implementation.

波动方程宽角抛物逼近得到的通常是非常系数的单程波传播算子，其系数是速度横向变化的函数，因此需要利用有限差分进行数值实施。

As Huber did, we prove the MacWilliams identity for Mannheim and Hexagonal distances, and conclude that the weight functions with the same symmetry group have the same U-weight enumerators.

和Huber一样，我们证明了两种距离之下的MacWilliams恒等式，由此说明有限域上对称群相同的两个重量函数的U-加权计数子的表达形式完全相同。

Because of the information asymmetry between fundholders and fund managers,and on the premise of limited rationality and opportunism of each sides,fund managerss behavior will in many situations conflicts with the utility of fundholders,thus producing the agency problems under the structure of investment funds.

在这种关系中，委托人与代理人之间的信息是不对称的，基于有限理性和机会主义的行为假设，加之委托人和代理人之间的效用函数不一致，代理人为追求自身效用的最大化，可能做出损害委托人利益的行为，从而产生了证券投资基金结构下的代理问题。

The set of feasible operations that allocate time optimally among the three heat conduction branches for the objective function be written in terms of the net effects and the finite-time constraint are explicitly described. The result generalizes the well-known result of Curzon and Ahlborn for the efficiency of a Carnot-like heat engine at maximum power.

描述了三个恒温热源之间一切可行的循环方式，在有限时间的约束下，根据净效果定义的目标函数对热传导分支运行时间进行了优化分配，推广了类卡诺热机在最大输出功率时Curzon和Ahlborn所得到的效率结果。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
