多方指数 meaning in Chinese
polytropic exponent
Examples
- Gas thermal insulation coefficient under different transient flow in pressure pipeline system has been studied through physical experiments and theoretical analysis on thermodynamics
本论文通过物理试验与热力学理论分析对不同瞬变过程中有压输水管道内气体的多方指数n的变化规律进行了研究。 - In the sub - process 2 of inflating and sub - process 4 of compressing , gas thermal insulation coefficient was 1 . 4 - 1 . 6 ; whereas it was 1 . 15 in the other two processes . 2nd
在压缩子过程4与膨胀子过程2中，气体多方指数n取值为1 . 4 1 . 6 ；而在压缩子过程1与膨胀子过程3中，气体多方指数n取值近似为1 . 15 。 - Some new ideas and main content showed in the article are as the follows . 1st . research on gas properties in pipeline system according to document references , by far there is no systematic research on gas thermal insulation coefficient in delivery pipeline with gas
论文研究的主要内容及创新点如下： 1 、管道系统中的气体特性研究已有文献表明，含气输水管道系统中气体多方指数n的变化规律至今还缺乏系统研究。 - The physical experiments and theories on thermodynamics prove that gas thermal insulation coefficient changes apparently when hydraulic transition process happens . so four appropriate processes were given - sub - process 1 of compressing , sub - process 2 of inflating , sub - process 3 of inflating , sub - process 4 of compressing
试验与理论分析表明，在管道系统发生水力过渡过程时气体多方指数n存在较为显著的变化，并非单一常数，从而提出了相应的四过程：即压缩子过程1 、膨胀子过程2 、膨胀子过程3和压缩子过程4 。
