By using the so called renormalization group method , we give a uniformly valid asymptotic expansions of the boundary value problems under consideration 利用重正化群方法,构造了该边值问题解的一致有效渐近展开式。
Using un - weighted pair - group method , the population living in similar ecological conditions and with close geographical distance clustered first 聚类分析表明,相似的生态条件及直线地理距离较近的种群具有优先聚类的趋势。
Analyzing the velocity and acceleration of the follower based on the assur - group method and the inversion of the mechanism . 4 3 .以杆组分析方法为基础,结合转化机构原理及凸轮机构的相对速度理论进行从动件的速度和加速度分析。
Renormalization group method which calculates fractal dimension theoretically is the most useful tool when we study critical phenomena of phase transition 重整化群方法是研究相变的临界现象最有力的工具,它是一种由理论求得分形维数的方法。
Wilson is the first scientist who applied renormalization group method to critical phenomenon . therefore , he opened the new frontier of the theoretical research of the critical phenomenon Wilson首次将重整化群方法应用到临界现象上,为临界现象的理论研究打开了新的一页。
