【摘要】 科技人员经常要对大量试验数据进行分析处理,以求找到一些变量间的因果关系。在进行数据处理时,会经常遇到非线性拟合问题。用三种线形为例,分别选择Exponential(自然指数)、Power(乘幂)和Boltzmann(玻耳兹曼)三种函数,以简单的操作步骤,进行非线性拟合,找出了变量间的因果关系,并举出应用实例。同时也介绍了拟合时应注意的事项及引申应用等问题。更多还原

【Abstract】 The scientific and technical personnel often obtain causality relationship of variables,realize analysis and processing of mass test data.During data processing,they usually meet problems of non-linear curve fit.Three curves are used as actual examples.The paper selects three functions: Exponential、Power and Boltzmann separately.Simple operating procedures are used to fit non-linear curve.Causality relationships of variables are fined.And actual application examples are enumerated.Meanwhile,the paper describes attention matters of fitting curve and extended applications.更多还原
