摘要
灌水率的大小关系到渠道断面的设计尺寸和工程成本。提出了灌水率图形调整的数学模型。该模型以保证灌水率方差在总灌水延续时间内最小和图像连续为目标函数 ,考虑了实际中 4种可能的调整途径及相应的调整规则。开发了可视化界面程序 ,该程序将整个灌水率的调整过程形象地反映出来 ,便于人机交互求解合理的结果。
The quantity of irrigation rate influences the design sizes of the canal section and the construction cost. A mathematical model for irrigation rate graph adjustment is proposed in this paper. Taking the minimum square deviation of the irrigation rate and successive images over the whole irrigation duration as objective function, this model considers 4 kinds of possible adjustment approaches and the corresponding adjustment rules in the actual applications. Visualization interface program of the model is developed, which can reflect visually the whole adjustment process of irrigation rate, and obtain rational results through convenient interaction between the user and computer.
