排气质量 meaning in English
abgasqualitaet
Examples
- But the nox mass flow rate ca n ' t measure directly , the only method to get nox mass flow rate is to know nox concentration in the exhaust and the exhaust mass flow rate , then indirectly obtain the rate by calculation
而柴油机排气中nox的质量流量不能直接测量，只能通过测量nox的体积浓度并确定排气质量流量或体积流量，才能推算出排气中nox的质量流量。 - This paper was detailed to introduce the measurement of main exhaust composition from marine diesel engine . at the same time , this paper discusses the computational method to get exhaust mass flow rate by carbon balance method and carbon / oxygen balance method
本文详细介绍了船用柴油机排气中各主要成分的测量方法，同时讨论了用碳平衡和碳氧平衡法计算排气质量流量的过程并编写了相关的计算程序。 - The only method to get nox mass flow rate is to know nox concentration in the exhaust and the exhaust mass flow rate . this paper discusses the computational method to get exhaust mass flow rate by carbon / oxygen balance method . besides the traditional computational method , this paper also demonstrates the possibility of applying bp neural network to predict no , emissions from marine diesel engines
由于大功率船用柴油机本身所固有的体积大、排气流量大以及测量困难等特点，使得排气中no _ x的质量流量不能直接测量，而只能通过测量no _ x的体积浓度并确定排气质量流量或体积流量，才能推算出排气中no _ x的质量流量。
