产品浓度 meaning in Chinese

product concentration

Standard test method for determination of radon decay product concentration and working level in indoor atmospheres by active sampling on a filter
通过滤膜上活动取样对室内空气工作水平和氡衰减产品浓度测定的标准试验方法
In the second place , based on the asu of buggenum igcc plant in netherlands , both static and dynamical model for distillation tower of the asu are created and some valuable conclusions are gained as well . finally , a compartmental simplified model is created for distillation tower of the asu , in order to reduce the simulation time and increase the simulation efficiency . the new model will be helpful to the further simulation and on - line optimal control for the asu of the igcc plant
其次，本文以荷兰buggenum电站的空分系统为原型，基于matlab建立了空分系统精馏塔的半图形化动、静态数学模型，并通过模拟，得出了一些有价值的结论：当空分系统的压力变化时，氧气产品浓度的响应时间常数为两小时左右，说明空分系统是igcc电站最大延迟环节；而且虽然氧气浓度最后会稳定在igcc电站所要求的范围之内，但在过渡过程中会超出限制，这些都为igcc电站的安全运行及控制系统设计提供了有价值的信息。
