The forecasts method including the forecast method of simple moving average , the forecast method of weighting moving average , the forecast method of single exponential smoothing , the forecast method of double exponential smoothing , the forecast method of multiplication model and the forecast method of monadic linear regression 预测方法包括简单移动平均法、加权移动平均法、一次指数平滑法、二次指数平滑法、乘法模型预测法和一元线性回归方程预测法。
In fact , the knowledge database is an experiential specialist system , which includes library classification , thesaurus , concordance of class number with descriptor , synonymous dictionary , keywords lists , stop - words lists , etc . after determining the indexing data of web pages , the method of weighted word frequency , which combined with statistical algorithms , is adopted to exercise the subject indexing of chinese web pages 在确定网页基本信息标引源的基础上,中文网页主题标引运用了基于词频的统计加权法;通过与分类号?主题词对应库主题词串的词面相似度计算,进一步完成中文网页的赋号标引,即分类标引。
This paper discussed the material of equipmen t which was used to prepare diethyl oxalate by co coupling - regeneration reactio n wi th the method of weight . the seven kinds of metal material , such as 306 , 314l , 316l , zr , ti ( 2 ) , ti ( 10 ) , 1cr18ni9ti and one kind nonmetal material ( pe ) have been hung in the liquid compound in the regeneration reactor for 1500hours . the experiment ind icative that the corrosion rate of the 306 is the biggest , in the after is 316l , t i ( 10 ) , 1cr18ni9ti , zincorium ( zr ) , ti ( 2 ) , that of pe is lest ; 1cr18ni9ti is the better material of equipment 沙河市散装水泥事业起于上世纪九十年代初,经过十多年艰苦曲折的发展,目前我市水泥散装率达到20 %左右,这一水平还达不到河北省水泥平均散装水平,与先进省市"发散"水平相比更是相差太远.我们对发达国家和我国"发散"先进省市的考察和对比分析,可以看出除国家行政推动外,市场有效需求是拉动散装水泥发展的重要因素
Factors which influence productive time of a working procedure , can be divided into several grades , four grades in this thesis , that is : { absolutely completion , completion , probable completion , unable completion } . corresponding elements of state sort table are adopted , that is four elements state sort table . connection number expression is found by the method of weighted value 对影响工序作业时间的若干影响因素( f _ 1 f _ n ) ,可以根据需要将评判结果分为几个级,比如分为{肯定完成,能完成,可能完成,不能完成}四个,那么应采用相应元数的态势排序表,即四元态势排序表;然后运用加权平均法求出工序作业时间的联系数。
In order to realize the feed business enterprises market - area building , according to the basic theory of voronoi polygon , this paper put forward a method of weighted - voronoi based on the raster format data analyzing the characteristics of weighted - voronoi polygon , expatiate the technique of weighted - voronoi polygon realization based on the raster data 为了实现饲料企业市场域的构建,基于voronoi多边形的基本思想,本文进一步提出了基于栅格数据格式的一种weighted - voronoi多边形的方法。通过深入分析的weighted - voronoi多边形的特性,阐述了基于栅格数据格式的weighted - voronoi多边形的实现方法,本文最终建立了基于gis的饲料企业市场域的构建模型和方法。
