1962年6月,我们在进行第二次行车试验时,对西德联邦铁路客车涂料性能继续进行了研究,并根据首次行车试验的结果,对试样材料作了选择和补充,在客车涂层的沾污方式中,原则上可将干燥沾污除外,因理论与试验均证实,在干燥沾污中起关键作用的静电力在潮湿沾污中不起决定作用,故本文不作研究。 In June 1962, during the second driving test, we conducted a study on the paint performance of the West Federal Railway Passenger Car and selected and supplemented the sample materials according to the results of the first driving test. In the passenger car coating In principle, it can be confirmed that the electrostatic force, which plays a key role in the drying of soils, can not play a decisive role in the wet soiling, so this article will not make any research.
