Examples
- Research manifests that : ( 1 ) allocation in the year of precipitation is very uneven , and yearly precipitation is different in great scope , negative anomaly of precipitation appear concentratly in the 1990s , the precipitation in the 1990s decreased in different degree ; ( 2 ) close positive correlation exists between runoff and precipitation , runoff is abundant in the year with prolific precipitation , and generally in the year with scarce rain the volume of runoff is not enough ; ( 3 ) there is 20 % margin in their changes amplitude , this mainly resulted from high frequent human activities
结果表明： ( 1 )流域内降水年内分配极其不均；年际变化剧烈，进入90年代后降水负距平集中出现， 20世纪90年代降水较多年均值有较大程度的减少； ( 2 )流域内河川径流与降水之间存在密切的正相关关系，降水量多的年份，河川径流丰富，反之较枯； ( 3 )河川径流积极响应降水的变化，然而河川径流变化幅度却比降水变化幅度大20 % ，这个偏差主要是由于频繁的人类活动的干扰造成的。 - In 1997 , hefei bus company took part in jac jianghuai auto group company , became its basic place of bus production , including hefei xiandai chief department , yangzhou hongyun , taixxian qiaoxxing , and hefei xinma these four buses basic product places , producing and selling 6 - 12 meter middle and top grade buses , product includes five series , over 60 style , at present it can make 15000 all style buses in one year . it is known that the amount of selling of hefei bus company is increasing gradually . it sold all kinds of 1251 buses in 2000 , the income of it was 2 . 3 hundred millions yuan ; in 2001 , company sold 2100 buses , and the income was about 4 hundred millions ; it sold over 4200 buses in 2002 , the income broke through 10 hundred millions
同时，以65家废气排放大户脱硫工作为重点，实施广州市2003 - 2005年控制二氧化硫工作计划，全面推进工业饮食服务业脱硫降氮和节能降耗的工作，使2003年全市二氧化硫排放量控制在21万吨，比2002年削减1万吨，力保二氧化硫浓度年均值达到国家二级标准2004年排放量降到19万吨，比2002年削减3万吨，浓度优于国家二级标准2005年排放量控制在15万吨以下，比2002年削减7万吨，浓度继续优于国家二级标准。 - Annual average of surveys and gray system model are used to set up the expression formula and model construction methods of time - effect , and determination method of 9 is illustrated , so as to get relatively reasonable time - effect exponent . recursive regression method is applied for foundation of dynamic monitoring model . the mathematical model of deformation of the dams with joints or cracks is put forward , aiming at the nonlinear feature of such dams
利用测值年均值和灰色系统模型，对时效分量的表达式及建模方法进行了探讨，对的取法进行了论证，从而得到较优的时效分量表达式；提出了利用递推阻尼最小二乘法建立动态监控模型的方法；并针对带缝坝变形的非线性特性，研究了带缝混凝土坝的变形监控模型。
