Although some physiological effects of each component have been studied, the ability of Lei Zhen Zi as a combination form of nutrient supplement to scavenge directly free radicals, reactive oxygen species and reactive nitrogen species has never been investigated.

Chemiluminescence of the reaction of active nitrogen with CHBr_3;

Strong emission spectra in the wavelength of 620～820 nm were detected when iodoethane (C2H5I) was added to a stream of active nitrogen, and the 35 spectral peaks have been assigned to the vibra- tional transitions of the NI(b1Σ+→X3Σ-) band system.

Active nitrogen has been prepared by hollow-cathode discharge of N2 in a flowing afterglow system.

Being one of the important issues of global change,elevated reactive nitrogen has been increasingly concerned worldwide.

Glucose can support nitrogen fixation activity under dar.

And the rang of activity of nitrogen fixation was 8.

Contents include:transfer of proton and electron in FeMo protein,model of the dinitrogen activation by FeMo cofactor,function of molybdenum atom in nitrogenase,measure for activity of nitrogen fixation.

In the reaction system of fixation nitrogen, the reduction potential within the cell of Azotobacter vinelandii was shifted to negative by increasing suitable hydrogen atmosphere, which resulted in the activity of nitrogen fixation increased.

Reports the determination results of nitrogenase activity of induced cucumber root nudules by 15 N trace method.
