Thus this method could be applied to monitor the process of producing dinitrogen pentoxide by electrochemical oxidation of dinitrogen tetroxide in nitric acid. The results from the two-step titration method of redox titration combined with acidity titration were well consistent with that from the method of redox titration combined with NMR.

In order to understand the adaptation of the microorganisms under the extreme cold environment conditions, the physiological characteristics of the 5 bacterial isolates from the Muztag Am ice core under the different temperatures were investigated. The csp gene was also amplified by PCR technique and the specific primer targeted for the cold shock protein. The observation results showed that there were three phenotypes of microorganisms: psychrophiles growing from 0~23°С(the optimum temperature at 15°C), psychrotolerant with growth range at 0~40°C (the optimum temperature at 23°С), and the thermophile with growth range at 0~45°C(the optimum temperature at 30°C).

The results indicate seawater concentration has no effect on absorbency, pH, relative density, dry matter and water contents in Aloe vera leaves. While, seawater stress causes increased MDA and membrane penetration, decreased phytochroms, prolines and NO_3~--N. It is beneficial to plant growth when irrigation was done with 10% seawater, because of higher ratio of K~+/Na~+ and lower ratio of Na~+/Ca~(2+). In addition, the polysaccharide contents in Aloe vera leaves increase twice and triplication under 25% and 50% seawater irrigation respectively, the barbaloin contents increase over triplication in var. 75% seawater and over twice in var. 50% seawater and var. 100% seawater. However, when seawater concentration exceeds 25% the growth of plant was inhibited, biomass decreased, flowering time was deferred, Ca~(2+) content decreased caused by Na~+ accumulation in leaves.
