因为温暖的空气比冷空气能容纳更多的湿气，所以只有当大气中的水蒸气量随着温度的升高而增加时，相对湿度才会保持不变。
Because warm air can hold more moisture than cool air, the relative humidity will be constant only if the amount of water vapor in the atmosphere increases as the temperature rises.
采用机械阀门控制蒸气量，寿命长，手柄更舒适，长寿命按钮电源开关。
It adopts the mechanical valve to control the quantity of steam of steam with the long life, the more comfortable handle, the long-wait button.
在计算实验结果时，考虑了平衡釜出口气流中的溶剂蒸气量，使实验结果准确可靠。
In the calculation of experimental results the amount of solvent vapor in the outlet gas stream of the cell was taken into account. The accuracy of experimental results is reliable.
