First, we extend the general finite element method from the function surface to the parameter function. Second, we bring this kind of method into the design of rational Bézier minimal surface. Third, we transform the problem of Dirichlet energy function into the problem of minimizing a discrete objective function.

首先推广了函数曲面中的有限元方法，进而研究如何针对参数曲面使用有限元方法，并把该方法引入到有理Bézier极小曲面造型的设计中，从而将连续的Dirichlet能量函数极小化问题，转化为一个离散形式的目标函数的极小化问题。

First, we introduce the concept of polarizable Carnot group and give some new properties of its homogeneous norm. Then we construct a class of non-divergence equations as well as their nontrivial solutions. The failure of corresponding A-B-P type estimate and uniqueness to the Dirichlet problems in space~ follow.

首先引入可极化Carnot群的概念，给出了可极化Carnot群上齐次模的若干性质，然后构造了一类非散度型次椭圆方程及其非平凡解，由此证明此类方程Dirichlet问题的解在函数空间L~中不唯一，进而证明相应的Alexandrov-Bakelman-Pucci型估计不成立。

As a mature tools in risk management in the international financial market, stock index futures hasnt been put into trading in our country for a long time. One of the most important reasons is that it maybe disarrange the present market, and then results in the coinstantaneous reflection between the markets on stock index futures and the present stock.

作为一种国际市场上成熟的风险管理工具，我国迟迟没有推出，其中一个重要的原因就是怕出现市场操纵，进而引起股指期货和股票现货市场的联动反应。

It suggested that the disbalance between proliferation and apoptosis which might be relative to abnormal expression of c-myc may contribute to pulmonary vascular structural remodeling.

提示增殖和凋亡现象共存在于正常和处理大鼠的肺血管细胞中，也许c-myc等基因的导常表达导致了细胞增殖和凋亡的失衡，进而调节了慢性低氧肺血管结构的改建。

The effective prediction space concept is established, On the base of these, this paper deduces two representations' evaluating equation, one evaluates the prediction error and the other evaluates the prediction error in limited space. First, the error transfer characteristic among subsystems at different space locations is analyzed, and the direct transfer characteristic from discrete standard measure space to the workpiece measure space under measured in measure system is proven. Second, the error reconstruction condition and method of mapping from discrete standard measurement system to continuous standard measurespace are analyzed.
