This makes more and more people pay more attention to studies and applications of numerical simulation in thermal recovery. In this research, we have developed a reliable mathematical model for thermal recovery, which takes a full consideration of the effect of viscos, gravitical and capillary forces on the three-phase flow of gas, water and oil, the effect of the temperature on the medium characteristics of liquid and solid, the phase equilibrium of gas-liquid in each component, heat transportation including connection, conduction and radiation as well as heat losses in both the overburn and underlying strata. In the space discreation of the mathematical model, we have proposed a new method based on the improvement of the conventional nine-points difference approximation, which has a higher difference accurancy.

本项研究以热力采油的主要机理为基础，充分考虑在粘性力、重力和毛管力作用下油水气三相流动，考虑温度对各种流体和固体介质物性的影响，考虑每一组分中汽液两相的相平衡，考虑热在地层中的传导、对流和辐射以及上下盖层的热损失，利用热力学第一定律、质量守恒定律和流体迁移定律，建立了正确可靠的注蒸汽数学模型；在对数学模型进行空间离散时，利用控制有限体积积分法，对以往的九点差分近似作了合理的改进，使其具有较高的差分近似精度：结果表明，该公式的近似精度要比以往文献中所给的九点差分近似精度高，可以认为，在油藏数值模拟中，如果遇到非均质情况，使用这种九点差分近似更合理。

This paper concludes the ministerial concept of "constructing socialism and harmonious society" and diversified theories about economic development's goal, such as the harmony theory of human and nature, resource exility and harmony using theory, theory of the Limits to Growth, ability construction and social harmony perspective, harmony theory of asset balance, the social develop perspective making freedom as the basic of value system. The views above conclude the meaning of harmony development generally including reasonable using of resource, balance development of economic structure, defending the growing income differentiation, reasonable income distribution, strengthening democracy and law and so on.

本文对"构建社会主义和谐社会"的执政理念，对社会经济发展目标的各派理论作了一个简单的归纳；包括人与自然和谐论，资源稀缺性及和谐利用论，增长极限论，能力建设与社会和谐观，财富持衡和谐论，以自由作为价值基础的社会发展观，以上这些观点基本比较全面地概括了和谐发展的意义，包括资源的合理利用，经济结构的平衡发展，防止贫富差距两极分化，合理收入分配，加强民主法治等社会生活的各个方面的内涵。

Based on the fundamental theory of impulsive differential systems, employing Green formula, Gauss divergence theorem, Jensen inequality and Gronwall-Bellman inequality with impulse, we discuss the oscillation of impulsive partial differential systems by adopting reduction to absurdity and the stability in via of comparison theorem, respectively. Especially, we take an in-depth study on the oscillation of neutral impulsive parabolic systems and the stability of a class of nonlinear impulsive partial differential equations and obtain some useful conclusions.

本文以大量实际资料为基础，对粤东某一花岗岩风化壳稀土矿床的地质地球化学特征作了描述。

In the initial stage, there is little ice particles, and the rain water form mainly through the collection of cloud water and auto-conversion process. In the growing and mature stage, both the cold and warm rain processes are important. The collections of rain water and graupel with cloud water and the melting of graupel are very important to the rain water. Graupel grows mainly through riming cloud water and colleting snow.

在上述成功模拟的基础上，又对γ中尺度对流系统作了探讨发现，γ中尺度对流系统在不同发展阶段的微物理机制不同：初生阶段时，冰相粒子含量较少，雨水的增长以暖雨过程为主，即依赖碰并云滴和云雨自动转化形成；发展和成熟阶段时，冷雨和暖雨过程并存，雨、霰碰并云水和霰的融化对雨水的形成非常重要，霰主要通过淞附和霰碰并雪增长，雪主要通过淞附增长。
