例句与用法

1. In this paper a perfect and flexible experimental system of low nox combustion is established firstly . the influences of the temperature of combustion , the air excess coefficient , a certain amount of vapor added in advance , the temperature of preheated air , adding microwave into gas before combustion , gas recycling combustion and the mode of combustion ( diffused and premixed ) on nox emission are analyzed respectively . the combustion of liquid petroleum gas is simulated with phoenics 3 . 5
   首先建立了完善灵活的低no _ x燃烧实验系统，在实验系统上完成了燃烧温度、过量空气系数、预先加入一定量的水蒸汽、空气预热温度、对燃气预先进行微波处理、烟气再循环燃烧以及燃烧方式(扩散式与预混式)对no _ x生成的影响分析；采用phoenics3 . 5软件进行了液化石油气燃烧的数值模拟。
2. It is firstly found that the nox concentration increases rapidly when is less than 0 . 75 , which complements the staged combustion and the rich - lean combustion that are well considered currently as low nox combustion . it does not mean that the combustion must be the low nox combustion when < 1 . there is a limited least value of air excess coefficient
   对目前普遍认为的分级燃烧和浓淡燃烧可以降低no _ x排放的提法给予补充，即对一次过量空气系数有一个最小值限定，不是小于1的任何值都可以，低于最小限定值将是不利的，而且一次过量空气系数有一个最佳值。
