The problem of nature is becoming the core problem of the 21st century .The human's modern movements have already resulted in great exospheric disaster, and the ecological crisis has already brought serious negative effects to the development of modern economy and society. So it has become the focus problem of the philosophic research that how to recognize and deal with Marx's theories of human and nature.

The main characteristics of problem-based learning are:(1) Learning is student-centered(2) Learning occurs in small student groups(3) Teachers are facilitators or guiders(4) Problems form the organizing focus and stimulus for learning(5) Problems are authentic and ill-structured(6) Problems are a vehicle for the development of real-world problem-solving skills(7) New information is acquired and skills are trained through problem-solving process(8) Evaluation is authentic and performance-based.

同任何一种教学模式一样，基于问题的学习有着独一无二的优点，但本身也存在一定的不足。受中国传统文化的影响，中国的学生大多胆子太小，缺乏主见和创见，解诀问题的能力相对较差，学生的这些学习特点，从一定程度上阻碍了基于问题学习的具体实施。基于此分析，本文提出了一些适当的解决措施。

The gap element method is proposed in the paper for two kinds of problems, which include contact problem and gap joint problem. Elasticity contact problem falls into the category of unknown boundary value problems. It follows that the contact area and contact conditions or states can never be determined without special mathematical analysis, which is a very difficult work. The boundary conditions of the contact surfaces are deduced.

First, we introduce and discuss the various methods of multivariate polynomial interpolation in the literature. Based on this study, we state multivariate Lagrange interpolation over again from algebraic geometry viewpoint:Given different interpolation nodes A1,A2 .....,An in the affine n-dimensional space Kn, and accordingly function values fi(i = 1,..., m), the question is how to find a polynomial p K[x1, x2,...,xn] satisfying the interpolation conditions:where X=(x1,X2,....,xn). Similarly with univariate problem, we have provedTheorem If the monomial ordering is given, a minimal ordering polynomial satisfying conditions (1) is uniquely exsisted.Such a polynomial can be computed by the Lagrange-Hermite interpolation algorithm introduced in chapter 2. Another statement for Lagrange interpolation problem is:Given monomials 1 ,2 ,.....,m from low degree to high one with respect to the ordering, some arbitrary values fi(i= 1,..., m), find a polynomial p, such thatIf there uniquely exists such an interpolation polynomial p{X, the interpolation problem is called properly posed.

文中首先对现有的多元多项式插值方法作了一个介绍和评述，在此基础上我们从代数几何观点重新讨论了多元Lagrange插值问题：给定n维仿射空间K~n中两两互异的点A_1，A_2，…，A_m，在结点A_i处给定函数值f_i(i=1，…，m)，构造多项式p∈K[X_1，X_2，…，X_n]，满足Lagrange插值条件：p=f_i，i=1，…，m (1)其中X=(X_1，X_2，…，X_n)，与一元情形相似地，本文证明了定理满足插值条件(1)的多项式存在，并且按&序&最低的多项式是唯一的，上述多项式可利用第二章介绍的Lagrange-Hermite插值算法求出，Lagrange插值另一种描述是：按序从低到高给定单项式ω_1，ω_2，…，ω_m，对任意给定的f_1，f_2，…，f_m，构造多项式p，满足插值条件：p=sum from i=1 to m=Ai=f_i，i=1，…，m (2)如果插值多项式p存在且唯一，则称插值问题适定。
