现行建筑内部给水、排水设计秒流量计算方法有平方根法、经验法和概率法等。
Currently the methods of design flow rate for domestic drainage which are popularly used in the world include square root method, experience method and probability method.
作者结合工程实例，认为应修正设计秒流量计算公式，从而准确确定管径，做到技术先进、经济合理。
The author of this paper proposed a modified formula for flowrate per second calculation to precisely determine the size of pipeline and to make the design advanced in technology and reasonable cost.
分析其原因，主要是在控制器设计上未能突破秒流量相等条件的局限性。
The main cause is that the limitation of the condition of equality in metal flowrate has no been broken through.
