Based on the experiment, a mathematical model between the quantity of air drawing and the diameter of auxiliary pipe for the tapered T branch has been established.
在试验的基础上建立了锥形三通抽气量与辅助管管径的数学模式，与孔板三通比较，锥形三通具有抽气效率高、动力消耗低等优点。
The relationship among mass ratio of gas exhaust and steam extract and gas exhaust pressure Pc of the condenser and gas exhaust temperature t was detailedly described based on calculated results from a derived formula which reckoned that it was proper of 2～4℃ lower of the gas exhaust temperature t than the saturated steam temperature(i.
本文提出一个新定义的直接空冷凝汽器设计指标———抽气带汽质量比 ,并用导出公式的计算结果直观地说明抽气带汽质量比与凝汽器抽气压力Pc及排气温度t的关系 ,认为直接空冷凝汽器的抽气温度t比抽气压力Pc之饱和汽温低 (即Δt取值 ) 2～ 4℃较为合适。
Based on "twice delay separation method",an one-hour separation procedure for ~(138)Cs from fission products is designed and examined,which combined "deflation",Cs_3Bi_2I_9 precipitation and Cs_4(Si(W_3O_(10))_4)precipitation.
