The catalytic properties of silica rich zeolite prepared by adding extra silicon to REHY zeolite were investigated.

The major surgery were as followed:retinal breaks locating,cryotherapy,subretinal fluid drainaging,scleral buckling or encircling scleral buckling combined with intravitreal injection of cleared air.

Sub-micron silicon epilayer deposited by a novel Ultrahigh Vacuum Chemical Deposition System and fabrication of high frequency device;

By spreading resistance profile technology,Si epitaxy thickness value was obtained through measuring the changing of depth resistivity.

By means of a system of nutrient solution culture under greenhouse, the effects of different concentration of exogenous silicon (Si) on anti-oxidative system, reactive oxygen species, soluble protein and praline content, root activity and ion content in leaves and roots of Cabernet Sauvignon seedlings were investigated under salt stress condition (50 mM NaCl).

was used in this experiment as material, experiment has two part; (1) natural drought stress : soil relative water content is 70%(CK)、60%、50%、40%、30%、20%、10%、5%; (2) control drought stress : soil relative water content is T1:70~75%(CK)、T2:50~55%、T3:35~40% and T4:15~20%, other, exogenous silicon and abscisic acid were used to T1(CK)、T3 and T4, control drought stress treated about 10, 20, 30 days.
