In order to study the numerical method to solve the viscous incompressible flow with free surface, the 3-D mathematical model for steady and unsteady hydrodynamic problem had been established and closed by k-εbuoyant turbulence model. The algebraic coordinate transformation method was used to fit the free surface, the Runge-Kutta method of three step and second precision was devised to simulate the time step. A high precision up-winding compact scheme was studied for the convection term, and the generalized conjugate residual method was set to solve the Poisson equation.

为了研究粘性不可压缩三维问题的数值求解方法,本文从基本的Navier-Stokes方程出发,采用代数拟合方法处理自由表面,用三级二阶Runge-Kutta方法对时间步进过程进行了模拟,并且对对流项的高精度迎风格式进行了研究,给出了求解压力Poisson方程的广义共轭剩余法,从而建立了能够模拟有自由表面的粘性不可压缩问题的定常、非定常三维水动力学模型,并采用k—ε浮湍流模型对其进行封闭。

By regularly testing for HBV serological markers, assessing HBsAg-specific T lymphocyte response in vitro by the end of follow-up, and giving a booster dose and estimating anti-HBs anamnestic response thereafter, the study, for the first time, gave a comprehensive evaluation for five-year efficacy of a three-dose revaccination in non-responders based on persistence of anti-HBs, preservation of immunologic memory, and prevention from HBV infection, and in additon compared low-dose ID revaccination with routine-dose IM revaccination.

Determined by the specific geological background of Longhetun, the characteristics of the soil resources show abundant calcium and leaning to alkaline. Monomial indexes to evaluate the revisal coefficient of soil adapted to karst mountains areas were screened out combined with the function of karst dynamics system and analysis of characters of each factor about fertility in soil. Predigestion model to soil revisal coefficient monomial assessment was established by successful importation of the content of nutrition elements in plant body, latent efficient elements in soil and available thickness of soil in the cranny of epikarst according to the characters that three carriers of soil, soil water and karst water supply nutrition to plants and two layers of foundation consist of surface soil and soil in epikarst cranny, and several types of soil revisal coefficient and weather-soil productive potentiality were calculated, the results show that the soil revisal coefficient was even more practical after modification than before, which make up of innovation of this study.
