Morphological and physiological identification showed that NTG-01 was Gram-negative, short rod shape, with flagella around the bacteria, V-P test positive and Methyl red test negative. The bacterium can use glucose as carbon suource and produce gases. No H2S produced on TTS medium. Lysine decarboxylase and orthinine decarboxylase, catalase and gelatine test are positive. Arginine decarboxylase, dehydrolase, oxidase and urase test are negative. Sequencing and alignment of 16S rDNA showed that it shared a 99% homologous sequence with Enterobacter aerogenes.

结果显示菌株NTG-01为细菌，革兰氏染色阴性，短杆状，鞭毛周生，V-P试验阳性，甲基红实验阴性，利用葡萄糖产酸产气，不能在TIS培养基上产生H_2S，赖氨酸和鸟氨酸脱羧酶试验呈阳性，精氨酸脱羧酶和双水解酶试验呈阴性，氧化酶和脲酶试验阴性，接触酶和明胶液化试验阳性，但后者反应迟缓，一周后才观测到结果。

Vacuum pump, under pressure in their work should be able to discharge process vacuum equipment in all the gases produced.

真空泵在其工作压强下，应能排走真空设备工艺过程中产生的全部气体量。

C. discharge setup, vacuum ultraviolet spectral radiations in range of 120-200nm for the He H2 and N2 gases have been investigated. The relative radiation intensity as a function of the discharge current (100-600mA) and the influence of the gas pressure on it have been shown.

研究了He、H_2、N_2在120nm～20Onm范围内该装置的真空紫外辐射特性，获得了100～600mA电流范围内的辐射强度与放电电流的关系，以及充气气压变化对它的影响。
