查询词典 probability amplitude

Based on connotation of intensive land use and the evaluation principle of intensive deployment of city land,this paper establishes a set of scientific and practical index system in evaluating the intensive utilization of city land,and conducts a demonstration analysis in 13 cities of Jiangsu Province by the way of multifactor comprehensive evaluation,rank correlation coefficient and cluster analysis.During the last ten years from 1997 to 2006,the urban land use intensity had increased in all cites,but varied in amplitude and mode in different cities.Urban land use intensity was descending sharply from the southern and the middle to the northern part of Jiangsu Province,in which Nanjing was the tiptop and Suqian was the lowest .

从城市土地集约利用的内涵入手，依据城市土地集约利用评价的原则，从土地利用投入水平、土地利用程度、土地利用效率、土地利用生态环境质量等方面构建了一个具有三级层次结构的城市土地集约利用度评价的指标体系，并在此基础上采用多因素综合评价，秩相关系数和聚类分析的方法以江苏省13个地级市为例进行了实证分析，结果表明：（1）1997～2006年，江苏省13城市土地利用集约度都得到了提高，但是提高的幅度和方式不同；（2）不同城市，苏南、苏中和苏北之间城市土地利用集约度呈现出明显的城市和地域差异，其中，省会南京最高，苏北的宿迁最低。

By using this mechanical model in vibrating compaction, soil parameters were identified according to the equivalence of vibrating differential equation. The curve fitting method of amplitude versus frequency response was used for dynamic simulation based on the systematic dynamic equation of vibrating roller-soil system.
