本文提出了六种水流中溶解固体与流量关系的混合模型及其方程。这些方程可以用数字计算机表示成适合于统计分析的形式。然而，在实际应用中，一个主要的问题出现在确定哪个方程或模型是最适用的，因为数据往往适合两个或更多的方程同样好。在确定是否存在溶解固体的恒定组分时遇到了特别的困难。当仅使用总溶解固体或电导率进行浓缩时，该决定是最关键的。其他化学数据的检查，如果可用的话，沿着的知识流帮助决定哪一个模型是最合适的。其他问题可能来自于非随机趋势和存储容量-流量关系的变化等因素。在这些情况下，应谨慎地将方程扩展到实际数据范围之外，或对方程或常数项的物理或化学意义进行推断。
Six mixing models and a number of equations derived from them have been proposed for some possible dissolved solids-discharge relationships in streams. The equations can be put in a form suitable for statistical analysis by digital computer. In actual application, however, a major problem arises in determining which equation or model is most applicable because the data tend to fit two or more equations equally well. A particular difficulty is encountered in deciding whether a constant component of dissolved solids is present. This decision is most critical when only total dissolved solids or electrical conductivity is used for concentration. An examination of other chemical data, if available, along with knowledge of the stream help decide which model is most suitable. Other problems may arise from factors such as nonrandom trends and variations in the storage volume-discharge relationship. Under these circumstances, an extension of the equations beyond the range of actual data or inferences about physical or chemical significance of the equations or constant terms should be made with caution.
