函数元素

That version takes an extra argument that is the name of a function to use to compare the elements.

这个版本需要一个额外的参数：实现元素比较的函数名字。

According to the principle of continuity of wave function, when different elements react with each other to form compound, the electronic densities of atoms at interface must be equal. Each atom should change the atomic radius to shift their electrical density, then this made huge micro-stress in atoms.

在单质元素原子形成化合物时，由于要满足量子力学的波函数连续原理，要求原子界面上的电子密度相等，各原子在化合时必须通过改变原子半径以达到相同的原子边界电子密度，从而在原子中产生了很大的微观内应力。

That is, formally speaking, a representation or encoding over an alphabet ∑ of a set D is a function f from D to 2^∑* that satisfies the following condition: f(e1) and f(e2) are disjoint nonempty sets 不相交的非空子集 for each pair of distinct elements e1 and e2 in D.

形式地说，对信息对象集合 D 进行基于字母表∑的物化或编码是从 D 到 2^∑*的函数 f，并且函数 f 满足以下条件：对于 D 内任一对不相同的元素 e1 和 e2，f(e1)和 f(e2)是不相交的非空子集。

For this method, integeral was proceed by triangular Gaussian quadrature method in polygon domain, which can reduce computational time greatly. Neighbor nodes database was create which can reduce neighbor nodes searching time. Rock and soil cutting problem are two complicated problems, so a robust method is needed to treat essential boundary condition.

岩土掘削数值分析要求无网格法拥有高效而适应性强(来源：ABC论文f1网www.abclunwen.com)的本质边界条件处理方法，本文提出一种新的处理方法，该方法通过改变边界节点权函数使试函数通过边界节点，并采用对角元素改1法满足本质边界条件，该方法灵活性强，适用于各种岩土掘削问题。

But the introduction of new basis functions also poses a new problem, that is, the complexity of computation of two matrixes' elements in the derivative generalized eigenvalue problem in NMM. Fortunately we found a recursive algorithm and solved it concisely.

在引入幅度基函数和斜度基函数后，广义特征值问题中矩阵元素的计算变的繁琐，我们运用一种递推算法简洁地解决了这个问题。

In the method, the symmetric positive semidefinite matrices are updated to approximate the Hessian matrices of the elemental objective functions and their sum to approximate the Hessian matrix of the objective function.

算法用对称半正定矩阵作为元素目标函数的Hessian阵的近似，使得其和仍然保持目标函数的Hessian阵的某种稀疏性。

The variograni of No.100 ore-body in three directions have been calculated, and the variogram curves were formulated. All these curves are leap type. The mathematical models of grade variability of Sn. Pb.. Zn.. Sb and Ag have been established respectively, the structural analysis of No.100 ore-body indicates the ore-body varies band anisotropically.

计算并拟合了100号矿体三个方向的变异函数，各变异函数曲线均为跃迁型，分别建立了Sn、Pb、Zn、Sb、Ag五元素的品位变化的数学模型，结构分析表明100号矿体呈带状各向异性变化。

The loop's body contains code that passes the values of two members from the current item to a function.

循环体中，代码把当前元素的两个成员的值传入一个函数进行处理，为了好记些我把这个函数记为

This paper establishes cubic spline function, analyzes subsection curve function and curve slope and curvature, at last decides to place the curve especial points which can be obtain easement curve length and other line parameters, such as the ZH point (end of line and beginning of transition curve), the HY point (end of transition curve and beginning of circular curve), the QZ point, the YH point (end of circular curve and beginning of transition curve), the HZ point (end of transition curve and beginning of line).

针对公路平面线形的8种组合类型，其线形元素特征则由最基本的直线、圆曲线、缓和曲线组成的特点，解析三次样条函数模型，得分段曲线函数、曲线斜率、曲率，从而确定曲线特征点（直缓ZH点、缓圆HY点、曲中QZ点、圆缓YH点、缓直HZ点）位置，进而得到曲线缓和曲线长度及其他线形参数。

After analyzs the key elements in social agents, sets up negotiation model among social agents based on argument, and sets up relative decision funciton; then based on the hypothesis of relative datum, analyzes the validation of the model and decision function through relative calculations with an nagetiation example of social agents in multi-agent society, and makes a simulation of its argument dialogue about this example based on defining the locutions of relative negotiation.

通过对Agent间存在的有关社会性的关键元素进行分析，建立了基于辩论的社会性Agent间的谈判模型，并建立了相关的决策函数；然后通过一个存在于多Agent社会中而具有社会性的Agent间的谈判实例，在假设了相关数据的基础上对模型和决策函数进行了举例计算，分析验证了其有效性，并在对相关的谈判原语作出定义的基础上对此谈判实例的辩论对话过程进行了模拟。

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。
