简述世界上多数国家是以均匀系数反映喷洒的均匀程度。目前、我国采用的均匀系数计算公式,系五十年代从苏联引入,一般理解为均匀系数应大于0.8。但是在实际的规划设计中,能够达到这个指标数量的并不多,大部份仅满足于不漏喷。显然,这样低的均匀度要求是不能期望喷灌效益充分发挥的,造成这种现象 Brief Description Most countries in the world use uniform coefficients to reflect the uniformity of spraying. At present, the formula for calculating the uniform coefficient adopted in our country was introduced from the Soviet Union in the 1950s. It is generally understood that the uniform coefficient should be greater than 0.8. However, in the actual planning and design, the number of indicators that can reach this level is not large, and most are only satisfied with leak-proofing. Obviously, such a low uniformity requirement can not be expected to give full play to the benefits of sprinkling, causing this phenomenon
