1·This quantity is called the universal gas constant.

大小只能被设置为常数。

2·This quantity is called the universal gas constant.

这个量叫做普适气体恒量。

3·It's the gas constant per molecule, rather than per mole.

即单个分子的气体常数，而不是每摩尔的。

4·Description of ascertaining flue gas constant and its relation to monitoring quality were presented.

阐述了烟气气体常数的确定及与烟尘监测质量的关系。

5·The operating principle, structure and advantages of dual controlled gas constant pressure valve are analyzed.

分析了双控燃气稳压阀的工作原理、结构和优点。

6·The ideal gas constant doesn't change, temperature doesn't change, and so v we just have minus nRT integral V1, V2, dV over V.

理想气体常数不变，温度也不变，因此,是负的nRT，积分从v1到v2，dv除以。

7·Otherwise, the value R of the gas constant and value K of adiabatic exponent can not be determined and the subsequent calculation also can not be conducted.

否则，气体常数值，绝热指数值无法确定，后续计算也无法进行。

8·It is well known that when gas is cooled at a constant pressure its volume decreases.

众所周知，当气体在定压下冷却时，它的体积减小。

9·The maximum penetration depth of gas flow is increased with the increase of gas momentum while the diameter of oxigen gunjet keeps constant.

气流的最大穿透深度随气体动量的增加而增加，而氧气喷枪的直径保持恒定。

10·So for an ideal gas then, dH/dp under 0 constant temperature, that has to be equal to zero.

所以对于理想气体,偏H偏p在恒温下，等于。
