n.r,universal gas constant 参考例子 1.This quantity is called the universalgas constant. 这个量叫做普适气体恒量。 2.The operating principle, structure and advantages of dual controlledgas constantpressure valve are analyzed. 分析了双控燃气稳压阀的工作原理、结构和优点。
气体常数（又称通用气体常数或理想气体常数，通常用符号R表示）是一个在物态方程中联系各个热力学函数的物理常数。（气体常数与阿伏伽德罗常数的比为波尔兹曼常数。）这是表征理想气体性质的一个常数。气体常数相当于玻尔兹曼常数，但以每摩尔每温度增量（而不是每个颗粒每温度增量的能量）表示为能量单位（即压力 - ...
