It can evaluate the mass loss caused by evaporation in vacuum, obtain a saturated vapor pressure-temperature equation, and provide a means to verify saturated vapor pressure at normal temperature.

为预测其在真空下长期使用中的蒸发损失量，以及验证在常温下的饱和蒸气压指标提供了一种方法。

As the result of evaporation loss, oil will be less in quantity and lower in quality, and the dispersing oil vapor will result in air pollution and potential fire hazard.

油品蒸发损耗不仅造成油品数量的减少、质量的下降，散失到大气中的油蒸汽造成了空气污染，而且还形成了潜在的火灾危险。

Results: The average loss rate of Paeonal sterilized by microwave was 22.76%, and that by circulating vapor was 38.04%.

结果：与灭菌前比较，微波灭菌丹皮酚平均损耗率为2 2 .76 % ，流通蒸汽灭菌丹皮酚平均损耗率为38.0 4 %。

You start to see the problem, because even the most focused lasers can experience a loss of signal when it passes through water, water vapor, etc.
