摘要
皮尔逊Ⅲ型曲线(P-Ⅲ曲线)是水文频率计算中使用频率较高的线型,海森几率格纸为绘制P-Ⅲ型曲线的首选格纸。采用在已有的海森几率格纸上手工点绘,由于格纸坐标划分的不均匀性,点绘精度不易掌握。针对该问题,应用Microsoft Visual Basic 6.0软件,结合Microsoft Excel 11.0 Object Livraryd动态链接库开发了P-Ⅲ型曲线适线软件,实现了海森几率格纸的自动绘制与调整,对格纸坐标的实时监控,及P-Ⅲ曲线的自动拟合。该软件具有良好的精度,较强的交互性和通用性。
Pearson type Ⅲ curve is often used in linear hydrologic frequency computation and Hazen probability paper is the preferred grid paper to draw Pearson type III curves.Dot painting is carried out by hand on the current Hessian probability paper,but the precision of dot painting is not easy to master,because of the inhomogeneity of coordinate system on grid paper.In view of this problem,Pearson type III curve fitting software was developed by the combination of Microsoft Visual Basic 6.0 software and Microsoft Excel 11.0 Object Livraryd dynamic link,which realized the automotive drawing and adjusting of Hazen probability paper,the real time monitoring of the coordinate system of grid paper,and the automotive fitting of Pearson type III curve.The proposed software is of good precision,strong interactivity and universality.
