最后，在全文研究工作的基础之上，本文提出一种"极限式循环操作"反应技术的设想，利用该反应技术能够最大限度地提高丙烯腈的选择性，降低深度氧化产物的生成，在节省资源和环境保护等方面均具有突出的应用意义。

The characteristic approximation is used to handle the convection part along the direc-tion of fluid namely characteristic direction to ensure the high stability of the method in approximating the sharp fronts and reduce the numerical diffusion; The mixed finite element spatial approximation is employed to deal with diffusion part and approximate the scalar unknown and the adjoint vector function optimally and simultaneously; In order to preserve the integral conservation of the method, we introduce the modified characteristic method.

该方法对方程的对流部分沿流体流动的方向即特征方向离散以保证格式在流动的锋线前沿逼近的高稳定性，消除数值弥散现象；对方程的扩散部分采用最低次混合有限元方法离散、同时以高精度逼近未知函数及未知函数的梯度；为保证方法的整体守恒性，在格式中引入修正项。

With economic development, the rock material is widely applied in the water conservation、 resources mining、 the civil construction 、 the railway and so on, a lot of problem about rocks urgently is demanded to solve, so there are very important theory and realistic meanings to thoroughly research its nature、 concerning and destroying mechanism,Due to natural function, massive joint and crack with rock, though the scale of these is small, it changes mechanics nature of rock greatly and reduces deforms mould and intensity parameter, and makes it presenting aeolotropy .

随着我国经济建设的发展，岩石材料被广泛应用于水利、资源开采、土木建筑、铁路等领域，与此同时出现许多岩石方面迫切需要解决的问题，所以对其性质、本构关系、破坏机理的深入研究有重要的理论意义和现实意义。由于天然作用，岩石内部存在大量的节理和裂隙，虽然这些裂隙的规模不大，但裂隙的存在大大地改变了岩体的力学性质，使其变形模量及强度参数降低，且使岩体的力学性质呈各向异性。
