The pH value in soil was significantly increased in litter aqueous extract of four decomposition stages. The NH+4-N concentration was significantly decreased in soil amended with litter aqueous extract of 10-day decomposition which promoted the growth of Aerobic azotobacter and Ammonifier but inhibited the growth of Aerobic cellulose-decomposer. Available phosphorus concentration was significantly increased and phenolic acid content was significantly decreased in soil amended with litter aqueous extract of 60-day decomposition which inhibited the growth of Aerobic azotobacter but promoted the growth of Aerobic cellulose-decomposer.

A decline in iodine value is sometimes used to measure the reduction of dienoic acids during the course of autoxidation.

有时，碘值的下降用来测量在自动氧化过程中二烯酸的减少。

The effects of acidity, reaction temperature, feeding mode, and rotational speed of the stirrer on the particle size of AC blowing agent were studied. The optimal conditions were obtained as follows: the catalyst composed with m:m(V2O5)=1:1 equal to 1%-2% ratio of the reagent''s mass,reagent reacts at 50℃ under pH=3-4 for 25min with 350～360r/min of the stirrer speed, and the NaClO3 solution must be added from burette.
