用毛细管测定液体的表面张力系数时,一般测量毛细管内径的方法是用咀将水银吸入毛细管,量出水银柱的长度,称出水银的质量,然后算出毛细管的内径。这样但不操作手续麻烦,而且水银有剧毒,操作时很不安全。我们实验室在初建时期也没有读数显微镜和焦利秤仪器来测定液体的表面张力系数。 Capillary capillary liquid measurement of the surface tension coefficient, the general method of measuring the capillary diameter is to use mercury to inhale the capillary tube, the mercury out of the length of the column, weighed the quality of mercury, and then calculate the capillary diameter. This does not bother with the procedures, and the mercury is highly toxic and unsafe to operate. Our laboratory in the early days nor the reading microscope and Joli instrument to determine the liquid surface tension coefficient.
