利用该有限元模型分析了钛合金铣削加工中切削力和切削温度的周期变化规律，建立了切削力和切削温度曲线。

And use the prior and more consummate ways to carry through vaneaccidence design, These ways have own technology points and disadvantage, In this paperstressly discuss the momentum-element theory way, this way was developed in the basic ofthe two ahead ways, and it overcome their defect. It also use element theory to deal withvane design. In the vane designing and aerodynamical characteristic calculating they bothrelate with intervene gene, so the keystone is to carry through the intervene gene in twocase, thereout to do the vane design and aerodynamical characteristic calculating.

运用翼型的基本概念和风力机叶片的基础外型参数进行叶片设计的预研讨论，并分别运用了Glauert和Schmitz叶片设计方法叶片进行初步设计，这两种方法有其各自技术特点和缺点，文中还着重研究了动量—叶素理论方法，这种方法在前两种设计方法的基础上发展而成，并采用两者的叶素研究方法进行叶片设计，动量叶素理论方法在进行叶片外型设计和叶片气动特性计算都涉及到干涉因子，文中重点对设计和计算情况下的干涉因子进行处理，并由此来设计叶片的外型和进行气动特性的计算。

In the light of the complex, high-level and non-linear feature of the mathematical model which describe the transport of the coalbed methane, this paper study the fully-implicit solving method of the mathematical model in detail. Based on the complexity of the algebraic equations which are formed eventually, according to the alternating direction implicit difference pattern, this paper use the iterative method and the fully main element Gauss-Jordan eliminating method to solve equations, which is to use the iterative method to determine coefficient matrix and use the fully main element Gauss-Jordan method to solve th linear algebraic equation group, at the same time of studying the solving method of the mathematical model, according to the devising requirement of FORTRAN77 program structure, this paper draw up computer program and form the corresponding computer model, and verify the validity and reliability of the model in theory by operating the model.
