论强势文化传播的主要特点

On the spread features of powerful culture

文化是人类在社会历史发展过程中所创造的物质财富和精神财富的总和,特指精神财富.文化之间的交流并不总是双向的,在相互影响过程中其作用力和效果是有区分的,能够对其他文化充分单向流动并且影响明显的就是强势文化.本文通过对这一复杂的通过器物、制度、行为、意识等层面互动过程的比较分析中,从空间流向、突破点、工具特征、个体作用、互动关系、时间等方面初步探讨强势文化传播过程中存在的主要特点.

To the difficulty of the conventional finite element method resolving the diffusion-dominated sedi- ment movement equation, the numerical model and its error analysis of 1-D convection-dominated sediment movement are constructed by the characteristic finite element method in this paper. The hydrodynamic model is computed by Matlab. From the comparison numerical between solution and analytic solution, and the result of numerical simulation of data measured practically by HeJin Measuring Station from 1969 to1999, it can be learned that the numerical model has a perfect simulation to sand content measured by HeJin in 31 years . So the numerical model in this paper can be used to simulate the river of high sand in a period of time.
