6 . through theoretical analysis and mathematical derivation , the relation between main pipe distribution and the cost was obtained . 7 5 .通过理论分析和数学推导,得出了有关自压喷灌系统中各主要管道布设规格与投资间的关系式。
But those two methods could only solve the problems of uneven uniformity , and have little contribution to save the total investment 但是用这两种方式仅仅能来解决喷灌的均匀度不均的问题,而无法降低喷灌系统一次性投资和使用维护费用。
Finally , by using this software , we designed a small residential sprinkler irrigation project . we got the result of the calculation and budgetary estimate conveniently 最后应用该系统对一小型住宅微喷灌工程进行了规划设计,很方便地获得了该微喷灌系统的计算结果、概算表等。
In order to proof the accuracy arithmetically , i developed a simulation program in vc + + to compare the new controlling system with the two frequently used traditional ones in the irrigation system 并在vc平台上开发了一套仿真软件,对在喷灌系统中常用的两种控制方式与新型的控制方进行了对比。
