本文从理论分析和数值模拟探讨了槽蓄演算方法的某些数学观点。为了消除演算开始几个时段出现出流量小于原稳定流流量的不合理现象,探讨了两种演算方法的最小计算时段。对改进的马司京干法进行研究,发现了当采用适当的计算时段长时,流量权重因数可扩展至1.0。分析了“相对槽蓄量”概念,指出校正初始槽蓄量是不必要的。对槽蓄量与示储流量关系的经典的最优线性拟合法进行了研究,并举例说明这种系统识别方法是不可靠的。最后讨论了应用参数随流量而变化的可能性。
In this paper, we discuss some mathematical views of the method of calculating slot storage from theoretical analysis and numerical simulation. In order to eliminate the unreasonable phenomenon that the flow rate is less than the original steady flow in the first few periods of the calculation, the minimum calculation period of the two calculation methods is discussed. A study of the improved Masstone method shows that the flow weight factor can be extended to 1.0 when the proper calculation period is adopted. The concept of “relative slot storage” is analyzed. It is pointed out that it is unnecessary to correct the initial slot storage. The classical optimal linear fitting method for the relation between reservoir capacity and reservoir flow is studied, and an example is given to illustrate that this system identification method is not reliable. Finally, the possibility of changing the application parameters with the flow rate is discussed.
