vacuum evaporating meaning in Chinese

真空喷镀
真空蒸镀

Vacuum evaporated layer
真空蒸发层
The main contents and results are as follows : ( 1 ) coating cracks were sealed or narrowed by vacuum evaporating an al film of 3um . wight losses of sic - c / sic in simulated air at 500 , 600 and 700 were all remarkably reduced , but the values were still large
主要内容和结果如下： ( 1 )真空蒸镀约3umal膜，涂层裂纹被封填或宽度减小， sic - c sic复合材料在500 、 600和700模拟空气与氧气中的氧化失重显著降低，失重值较大。
The experiment took water as the medium and experiments on two jet modes were carried out under the falling film vacuum evaporating . the experimental results indicated that the two ejectors in series compensation method could adjust the variational work situation due to the decrease of primary steam or secondary steam and insure the normal production . at the same time , the ejector ' s best work situation founded in the experiment would provide reference for ejector ' s design and usage
本实验建立了一套降膜真空蒸发装置，以水为介质，对变工况下单级和串联喷射热泵蒸发进行了实验，结果表明两级串联补偿喷射装置能对由引射蒸汽和工组蒸汽压力降低所造成的混合蒸汽压力降低进行调节，达到了变工况下正常生产的目的。
