On the basis of relevant boundary conditions and the establishment of reasonable numeration model , this paper analyzes underground structures through utilizing fem ( finite element method ) 本文通过采用适当的边界条件,建立合理的计算模型,运用有限单元法分析地下结构地震反应。
This paper discusses the numeration of the positive integer , negative number and fraction in suanshushu , and points out its characteristics and its roles in the history of mathematics 其中正整数、负数、分数的记载和表述方法与后世算书及其他国家和地区的记数法比较独具特色,其形式在一定程度上反映了先秦数学发展的某些特点。
When analyzing the intensity of the drum with the simple numeration and the analogism or the shell theory , the calculative result is not very precise and it " s difficult to describe the nice change of the stress distinctly 采用粗略的简化计算法及类比法或者用板壳理论等方法对滚筒进行强度分析,计算结果不是很精确,应力的细微变化也很难描述清楚。
