A study on the migrating rule of Hg,As,Cr,Cd elements in food chain;

Transfer of amino acids in the food chain of key species anchovy(Engraulis japonicus) of the Yellow Sea and East China Sea food web;

Biotransfer and bioaccumulation of Cry1Ab insecticidal protein in rice plant-brown planthopper-wolf spider food chain;

Translation of selenium in the system of soil-plant and it's regulation in food-chain.;

Influence of N, P additions on the transfer of nickel along the food-chain;

Qualitative analysis of a food-chain system with stage structure and time delays;

Advance in the aspects of modifying sequence structures and microstructures of polymers, initiating chain transfer reactions, functionalizing polymers using potassium alkoxides and phenoxides as promoter in the application of anionic polymerization were summarized with 42 references.

Based on the mechanism of chain transfer to hydrogen,effect of electron donor on the role of hydrogen as a controlling agent of relative molecular mass,the effect on stereoregularity of polypropylene,and effect of activation were reviewed.

Experimental results indicated that the sequence of chain transfer constants in solvents was arranged as carbon tetrachloride > chloroform > methylbenzene > tetrachloroethane in the polymerization of octodecyl acrylate.
