) seeds were desiccation sensitive when shedded.

This study aims to discover the relationship among browning, the contents of soluble sugars and desiccation sensitivity in chestnut seeds.

The activity of reactive oxygen scavenging enzymes, membrane lipid peroxidation and electrolyte leakage in embryos of wampee seeds during desiccation were measured in order to investigate the physiology of desiccation sensitivity in recalcitrant seeds.

) Skeels] seeds were chosen as materials to study the effect of KCN pretreatment on the desiccation sensitivity of recalcitrant seeds.

The effect of boron content on decarburization sensitivity of medium carbon high strength spring steel was investigated.

Study on water sensitivity of the porous media at saline-freshwater interface;

Based on the investigation,in-situ and Lab tests on Malan loess carried out in Utrecht University of Netherlands and Lanzhou of Gansu Province with different methods,the water sensitivity,the hydraulic and shear strength properties of Malan loess were studied.

Based on the study of water sensitivity and water stability of bitumen mixtures,the evaluation of water damage resistibility of the mixtures is analyzed,with eroding and freezing/thawing test to simulate water damage of bituminous surface,and the indexes of residual splitting tensile strength(RSTS) put forward.

Four vegetation characteristics indices including sensitive level,landscape importance value,information index of species diversity and company species number have been calculated to analyze impacts of tourist development on landscape characteristics of vegetation in Yaoluoping reserve.
