5 summary a subsurface runoff model with water storage and recharge is developed in this paper based on the bous - sinesq - storage equation . the sensitivity of the model parameters is also tested . the subsurface runoff model is applied to a river basin with observed precipitation , observed air temperature data , observed runoff data , and a base flow separation algorithm in order to vali - date the model application 5结论与讨论基于boussinesq - storage方程发展了同时考虑水分储存和入渗的地下径流机制,分析了模型参数的敏感性,并针对淮河流域的的息县控制站所控制的区域,利用降水径流资料及通用的基流分离算法进行了验证
By adopting the layered architecture , two - lever state machine , message queue based publish / subscribe pattern and rules expressed in xml , by using technologies involved in activex , xml and distributed components , icall - aldp provides application developer with supports as rule - based flow process , asynchronism and concurrent message process , external system communication - oriented protocol - transform , and dynamic expand of components 通过使用activex控件的动态加载机制、连接外部系统的通信协议转换机制和基于元数据的柔性机制,增强了平台的可扩展性。在设计和实现中采用了activex 、 xml 、设计模式以及分布式构件等技术,实现了基于规则的流程处理、支持并发与异步的消息处理以及构件动态扩展的功能。
Thus , the next 1500 hours correspond to the base flow recession period . it is obvious that the aquifer with ampler water storage will produce larger subsurface runoff . from the above numerical simulations , one can see that the b - s model can reasonably simulate the subsurface runoff varia - tion in the two extreme conditions 而在持续了1500 h以后入渗突然都变为0对应着实际情况中径流的消退期,显然储水较多的潜水面的地下径流比较大,而随着退水的持续进行行,地下径流也越来越小
The pollution problems of the rivers and streams in that region have accordingly improved considerably in the past decade . however , as the base flow of local rivers and streams is generally small , their assimilative capacity is therefore low . this , coupled with the continued development and hence population growth in the river catchments , as well as the lack of maintenance of many private septic tank systems , has caused the water quality of some rivers and streams in the northwest new territories to remain unsatisfactory 而溪流的污染情况在过去的十年间亦因此而有所改善,但由于本地河溪的流速相当慢,河流的自净能力相对偏低,而河溪的周边不断发展,人口持续增加,加上部分私人的化粪池系统欠缺打理,未能有效运作,所以新界西北仍有部份河溪水质未如理想。
Then the message - based flow control of main monitoring program in program - controlled instrument is brought forward . with the modeling and analyzing tools of the petri net and boolean matrix , the main monitoring program design method of a multi - dsp system is presented with the example of digital i / o wp module . chapter 6 illustrates the basic structure and design approaches to wp virtual instrument ' s software according to the vxi plug & play ( vpp ) specifications 第五章提出了向共享总线的多sharc系统执行“直接宿主机导入” dsp监控程序的新方法,随后又提出了基于消息的程控仪器主监控程序控制的概念,并以vvp数字i o模块为例,描述了利用petri网和布尔矩阵为主要建模和分析的浙江大学博士学位论文工具,实现了多dsp程控仪器主监控程序设计的新方法。
Following this algorithm , the base flow can be calcu - lated from the observed discharge as follows : 1 , 22bbqiqiqi where i is the time step in the discharge records , qb is the base flow , q is the total runoff , and is the re - cession constant during periods with no surface runoff . the parameter can be determined through a dis - charge recession analysis 地下径流的推算公式如下1 1 . 22bbqiqiqi ? ? ? ? 26其中i表示推算的时间步数, qb是地下径流, q是总的径流.表示没有降水时候流量消退系数,可以通过没有降水时候的流量消退资料推算出出来
