The "supersaturation ratio" is the ratio of the excess vapor density to the saturation value.

"过饱和比"是超过饱和值的蒸汽密度与饱和值的比。

Based on the analysis of the mathematics models of saturation steam density and superheat steam density the paper states that the deviation of the detection on temperature highly affects the accuracy of intelligent flow totalizer.

文摘：在分析饱和蒸汽和过热蒸汽密度的数学模型的基础上指出，温度检测的偏差对智能流量积算仪的精度影响极大，尤其是饱和蒸汽，测温电路的精度应设计为远高于仪表的精度，同时引入一种基于比率法的高精度测温电路。

But the miniaturization does come at the price of reduced stability: 2 parts in 1010 because in a miniature clock, the vapour cell is so short that the vapour density must be increased.

但是小型化的确是以牺牲稳定性为代价的，精度只有2/1010。这是因为小型钟里的蒸汽元件太小了，必须提高蒸汽密度。

The steam and nitrogen push uses steam as the heat source ,extra heavy oil or bitumen has been mobilized by conductive heating and rely on the action of gravity of condensed liquid to recovery heavy oil. Because nitrogen is noncondensible gas and its density is lower, nitrogen rise and accumulates in the top of the reservoir.

蒸汽―氮气辅助重力泄油的开采机理是以蒸汽作为热源加热油层，使高粘度的原油、沥青获得较好的流动性，利用气体和液体由于密度不同而产生的垂向分异作用，靠油的重力开采。

The steam generator, in the incorporate type of the high-temperature gas-cooled reactor, should be of the compact structure, the least heating surface and the higher power density in order to decrease the volume of the initial-stress concrete pressure vessel, there by the steam generator with the uniflow multi-start helical coiled tubes is used generally for it possessing all these characteristics.
