Using the KMnO4 titration method to detect the catalase activity and the sulfosalicylic acid method to detect the free proline content, the changes of catalase activity and free proline content of plants in Kaili area under air pollution were studied with the representative plants such as Camellia oleifera, Pinus massonina, Cunninghamia lanceolata, Woodwardia japonica and Dicranopteris pedata in Kaili area as research subjects.

Vancomycin was directly coupled onto Tenta Gel S NH〓 or PEGA resin through its C-terminus. HR/MAS NMR studies indicated that conformation of PEGA-bound vancomycin was the same as free vancomycin, and Ac〓-L-Lys-D-Ala-D-Ala interacts with PEGA-bound vancomycin the same way that it interacts with free vancomycin.

From the experiment discovered for the first time the dimethyl ether may substitute CO to take the chain-carrying agent of the peroxy free radical chemistry amplifier system, and optimized the CH_3OCH_3-NO-HO_2 chemistry amplifying system determination condition, the CH_3OCH_3 best density is 1.876 ppmv, the NO best density is 1.3ppmv, and obtained this method chain length CL=124, 5 parallel determinations densities of HO_2 are the 44.0pptv, the relatively standard deviation is smaller than 4%; Although chemistry box model computed result indicated the dimethyl ether, the ethene, the propene and the ethanol all can take the chain-carrying agent of the peroxy free radical chemistry amplifier system, and their simulation chain length all grows up compared to the CO-NO-HO_2 chemistry amplifying systems, but experiments proved the ethene, the propene and the ethanol have not suit the chain-carrying agents.
