Some phenomena were found that the microstructures of magnesium alloy were changed obviously:thick ness of grain boundary was reduced,the content of solute in the grain was incr eased apparently and reduced slightly in the grain boundary.

Soluble matter content in wheat ear,peduncle,flag leaf,and flag leaf sheath of the samples was measured using a PR-32 refractometer.

In order to elucidate the toxic mechanism of copper on one of green algae—interomorpha linza ,the effects of copper on the soluble protein content,membrane lipid superoxidation level and relative ionic leakage of E linza were studied under the various experimental conditions.

Comparative analysis of changes in soluble protein content in leaves, panicles and anthers among homozygous and heterozygous sterile plants and recessive fertile plants of Pingxiang Dominant Genic Male Sterile Rice (PDGMSR) in different young panicle developmental stages was conducted.

Bound water content and the ratio of bound water content and free water content increased significantly, along with the decrease of soil water, soluble protein content decreased and soluble sugar content increased, after soil water was recovered, all of which returned to normal level.
