摘　　要：实验研究了N2对于船舶压载水中浮游生物生长的影响,旨在探讨利用船舶惰气系统抑止或灭除船舶压载水中浮游生物的可能性。实验结果表明,由N2形成的惰性气体保护层能够对压载水中的生物的生长起到明显的抑止和部分致死的效果。同时实验对比研究了N2填充作为电解法处理船舶压载水的前处理与直接电解对压载水中生物灭除的效果,表明N2填充提高了电解法处理船舶压载水的处理效果。The influence of nitrogen, which is the main component of the inert gas and can be produced by the I. G.. S or the I. G. G equipped on an oil tanker, on the growth of phytoplankton and zooplankton in ballast water was studied. The study on the probability using inert gas systems to restrain or destroy plankton in ballast water was carried out. The experimental results showed that an inert gas protecting level was able to have an effect of restraining and partly destroying plankton in ballast water.
