中文摘要：

研究了注入三孢布拉氏霉（Blakesleatrispora）、里氏木霉（Trichodermareesei）、吸水链霉菌井冈变种（Streptomyceshygroscupicusvar．JingganggensisYen．）和凝结芽孢杆菌（Bacilluscoagulans）的氮离子（N‘）不同注量与存活率以及总抗氧化能力（T-AOC）的变化规律。结果表明：N’注入ZreeseLS．hygroscupicus和B．coagulans的存活曲线随着N’注量的增加均呈现“双马鞍型”变化，不同于离子注入典型的“马鞍型”变化曲线，并且N’注入B．trispora和T．reesei注量-T-AOC曲线与注量一存活率曲线呈现一致的变化趋势，由此推测，离子注入微生物所诱导的T-AOC的强弱很有可能决定微生物的存活情况。

英文摘要：

The relationships between doses-survival rate and doses-T-AOC of Blakeslea trispora and Tricho- derma reesei by N＋ ion implantation were investigated. The results showed that the curves of survival rate of T.reesei, Streptomyces hygroscupicus var. Jingganggensis Yen. and Bacillus coagulans were all represented ＂double saddle shape＂ with increasing N＋ implanted dose, which were different from the classic ＂saddle shape＂ curves. And the dose-T-AOC curves of B.trispora and T.reesei revealed the same trend as the dose-survival rate ones. It can be sug- gested that the variation of T-AOC probably decided the microbe survival situation after being implanted by low-energy N＋ ion.
