【摘要】 为了分析说明经验公式存在的客观性,解决问题的实用性,采用理论分析和大量事实验证的方法,以水文地质问题为例,根据原始数据建立各类数学公式,用曲线相关系数R值优选公式类型,适时地变化公式参数,建立了二元变量的适应型经验公式。认为适应型经验公式对揭示自然规律具指导意义和普遍的应用价值。更多还原

【Abstract】 To explain the objectivity and the practicality of modifiable experience formula to solve problems,the paper synthesizes plenty of facts and takes hydrogeological problem as an example.A method,which makes use of original data to model,correlation coefficient R of curve to establish formula type by changing formula parameters,is introduced to establish a modifiable experience formula with two variables.The method is significant and useful to reveal natural laws.更多还原
