本文建议了一个简单而有效的、在测量船上测量水面油膜厚度的方法。该方法在于从水域表面选取污水试样并利用玻璃漏斗型装置中液体的不可压缩性来增加试样中油膜的厚度。在油膜厚度为0.2微米至10毫米的范围内,所建议的装置在90％的情况下都可无故障地进行工作。每次测量所需时间低于5分钟。该方法既适用于暗色石油产品,又适用于有光亮的石油产品。 This article suggests a simple and effective way to measure the thickness of a water-based film on a survey vessel. The method consists of selecting a sample of sewage from the surface of the water and using the incompressibility of the liquid in the glass funnel to increase the thickness of the oil film in the sample. In the oil film thickness of 0.2 microns to 10 mm range, the proposed device in 90% of the cases can be trouble-free to work. The time required for each measurement is less than 5 minutes. This method is suitable for both dark and light petroleum products.
