The plant growth characters, nut shape feature and main nut economic trait for 50 superior plants of Xingshan Juglans Regia were studied.

In order to solve status that traits of economic forest plus trees and elite clones can not be scientifically and reasonably classified because of the difficulty in quantify quality index,the lack of system,relationship and comprehensive on the methods of growth index contrast and synthesis grade.

In order to solve the problems in the measurement of plus trees and clones, the plus trees and clones were classified by using the Fuzzy linear weighting transformation model combined with quantitative and qualitative indexes on the basis of surveying, selecting and clones tested for walnut in Bijie area.

Five dominant strains that can effectively degrade COD in leachate were selected based on a series of experiments,in which the concentration of leachate was increased step by step.

In order to attain dominant strains which can degrade phenol compounds, using the activated sludge of aeration tank and sedimentation tank at Tiexi gas works in Shenyang as origin of strains, phenol and resorcinol as substrate screening twelve kinds of strains.

Studies on the screening of fine strain and biological trait of Lactobacillus acidophilus;

This paper system atically summarized the methods and standards of screening out lactic acid bacteria fine strain.
