vacuum condensation

The degree of vacuum during condensation is in the order of 10-5 Torr.

凝聚时的真空度为10~（-θ）乇量级。

The paper calculates radiation heat from evaporation source and condensation heat which raise the temperature of the substrate during depositing foils with vacuum evaporation.

计算了真空蒸发制备薄膜时造成衬底温度升高的热量&蒸发源的辐射热和沉积时的冷凝热。

Vacuum breaks heat, heat preservation, the anti-condensation, braised burn already cooked porridge, type of stew, jasmine tea easily.

真空断热，保温、保冷，焖烧已煮好的稀饭、炖品、花茶轻松方便。

Effect of inert gas on evaporation and condensation process at high vacuum

惰性气体对高真空蒸发与冷凝过程的影响

Mixed acid as the catalyst, vacuum distilling condensation, the yield could be 53.

采用乙醛酸、尿素和回收滤液为原料,混酸为催化剂, 经真空蒸馏缩合制得尿囊素.
