以室内试验为基础，测定了重壤土、中壤土、砂壤土在不同滴头流量、不同灌水量下的点源入渗运动过程，通过对点源入渗特性的单因子分析表明，湿润锋水平、垂直扩散距离不仅与滴头流量、灌水量关系密切，与土壤特性(土壤容重、初始含水率)也存在良好的幂函数关系，得出了以土壤物理参数和湿润比及湿润深度为基础的点源滴灌滴头流量的设计模式

结果表明，死端过滤速率衰减模型中过滤速率与时间呈幂函数关系、而十字流过滤速率衰减模型中过滤速率与时间则呈一次函数关系，死端过滤时悬浮液浓度和气压过滤压力对其过滤速率衰减模型系数的影响均呈三次函数关系，在十字流过滤时悬浮液浓度、操作压力以及雷诺数对模型系数b的影响均呈线性关系，轴向流十字流过滤速率衰减模型系数b与欧拉数呈反比，而旋转流十字流过滤时则模型系数a与欧拉数呈反比关系。

In this paper,by using the idea of F-expansion method (where F is a known solution of an ordinary differential equation with fourth positive power nonlinearity),the problem of seeking the exact solutions of the generalized BBM equation with any positive power nonlinearity is changed into seeking the exact solutions of an ordinary differential equation with fourth positive power nonlinearity.

When they built up the quantum Liouville equation inthe phase-space representaiton and discussed the mathematicaltransformation of the wave functions between the coordinate ormomentum and phase space,Torres-Vega and Frederick alwaysassumed the positive series expansion in coordinate of potentialsof systems.This is obviously incomplete because potentials ofreal systems contains in general negative powers of coordiante.

Torres-Vega和Frederick在建立相空间中的量子Liouville方程以及讨论和推导相空间波函数和坐标或动量空间中的波函数之间的的数学变换时，总是假定体系的相互作用势仅能展成坐标的正项级数，这显然是不全面的，因为实际体系的相互作用往往都含有坐标的负幂项。
