摘　　要：对小孔周期性泄流实验进行了研究,发现小孔周期性泄流的形成除了与实验装置内外筒液体的浓度、黏度和相容性有关外,还与内外筒之间的空隙有关;周期的大小不但与内外筒液体的浓度、小孔孔径有关,还与内外筒的直径有关.Some experiments for the periodical leakage flow of small hole are performed. It is found that the forming of periodical leakage flow of small hole is not only related to the concentration, viscosity and compatibility of the liquid in the inner and exterior vessel, but also related to the crevice between the inner and exterior vessel. The change of the period is not only related to the density of the liquid in the inner and exterior vessel and the diameter of little hole, but also related to the diameter of the inner and exterior vessel.
