Being based on the acknowledgement of continuum medium hypothesis, it has made an analysis of some general movements of macro material, which points out that there are a series non-consistence problems in logic in the Cauchy's stress theory and Stokes's stress hypothesis, etc.

除了指出 Cauchy 的两个应力定理， Stokes 应力假设等存在的逻辑不自洽问题，并产生的原因进行了系统分析以外，演绎地构造了连续介质物质模型严格假设下的完整形式表述体系，并且演绎地导得这个演绎体系必然导致三维物质流形，在三维 Euclid 空间中恒为超定。

Since continuum hypothesis is still valid for liquid flow in microchannels with hydraulic diameter at about 100 micro-meters, a turbulence convection heat transfer model for single-phase liquid flow in microchannels is established, in which wall surface roughness viscosity is introduced.

分析表明水力直径为100μm左右的微管道内单相液体流动仍满足连续介质假设，引入粗糙度粘性系数，建立了微管道内单相液体湍流对流换热模型，并采用3维有限容积法进行了数值计算，将计算结果与实验结果进行了对比。

According to the hypothesis of continuum, a tube with the corner strengthened is gained to make an equal of the frame-tube. B3-spline functions and parabola functions are applied to simulate the displacement functions of the frame-tube. The system of equations about the undetermined coefficients of displacement functions is deduced by using energy-variational principle, by solving which the displacement of the frame-tube is gained. Then the internal forces in the columns and beams of the former frame-tube are obtained according to the principles of elasticity mechanics.

根据连续化假设将框筒等效为角部加强筒体，将三次样条函数与抛物线函数结合假定框筒的位移函数，运用能量变分原理推导出了关于位移函数待定系数的方程组，解得位移函数待定系数进而解得框筒的位移，再根据弹性力学原理确定原框筒中梁柱的内力。

The finite-element method can be regarded as an extension of the displacement method to two-and-three-dimensional continuum problem.

有限单元法可以看作是位移法对二维和三维连续体问题的推广。

With the rapid development of urbanization, almost all of the large cities in our country are facing the same problem which rural-urban continuum restricts the development of the cities.

随着城市化的快速发展，我国各大城市基本上都面临着同样的问题——城乡结合部对城市化发展的制约。
