The process of powder soution preparation operates each soution tank gade, they are bocked off. it coud assure the best reaction time invariabeness consistency of every soution tank, avoid any direct touch of prefabricated tank iquid storage tank, the automatic contro system ised with eve sensor, to gain the exactitude consistency. When the eve reaches ow, the soenoid vave open, the powder feeding started. Opposite, the eve reaches high, the circe process stop.

干粉溶液制备过程是通过各个溶液槽分级逐步完成的，溶液槽之间隔开，保证每个溶液槽内的最佳反应时间和恒定浓度，避免在预制槽和药液储存槽之间有任何直接通路，自动控制系统与储存槽上的液位控制器相连，一旦液位达到低位，触发进水电磁阀打开，干投机启动，投加量安装水量设定，以获得精确浓度，当液位达到最高点，此循环过程就停止，当然搅拌器还按设定时间继续工作。

After studying the characteristics of Particle Swarm Optimization,Particle Swarm Optimization is used in wavelet domain to optimize the thresholds,and garrote shrinkage function is used to process wavelet decomposition coefficients,which overcome the shortcoming of discontinuity of hard-threshold and decreased the fixed bias of soft-threshold.

研究粒子群优化算法的特性，将其应用于小波域，对阈值进行寻优，并使用garrote阈值函数量化小波分解系数，而garrote阈值函数既克服了硬阈值函数的不连续性，也减小了软阈值函数存在的恒定偏差。

Based on the Saint-venant equations describing the channel flow movement, the nonlinear algebraic equations derived by the use of Preissmann weighted implicit four-point scheme are solved with the Netwon-Raphson method. A combined Gauss main-element elimination method with compress-storage technique is proposed. The relaxation iterative method for solving branch river networks is extended, which can turn the problem of any complex river networks into the problem of a series of single rivers. The coupling of hydraulic model with water quality model is built up. The combined model was applied to a large complicated river networks with numerical hydraulic structure which influenced by strong tide, storm and heave rain. Visualization of computational results is realized by means of MapInfo, which displays the computational results in fast, convenient and accurate way.
