highest high water
1.The results were as follows: leaching solution by hot water extraction was date in color and had mellow date aroma and the highest fusel oil content but strong bitter taste; leaching solution by pectinase enzymolysis had the highest reducing sugar content easy for fermentation but excessively high methanol content in fermenting wine; leaching solution by microwave extraction had the shortest extraction time and fermentation time and the highest ethyl acetate content in wine and the produced wine had special aroma.
2.Natural colonies were insensitive to UV radiation. Its PSII photochemical activity could be reactivated under the sun light when re-hydrated, and was not affected by PAR, UV-A and UV-B. When re-dehydrated, the PSII activity decreased at the initial stage of water loss, then increased, and reached its highest value at the water loss of 70-90%, and then declined with further water loss under the high levels of solar irradiance.
3.Study on lab shows when the highest temperature is 140℃ and the highest salinity is 35×10 4mg/L, gel forming and curing time for plugging agent is 6～24h and can be adjusted in this scope, strength of plugging is above 20MPa ,which basically meet with requirements of chemical water plugging in high temperature and high salt reservoir in Zhongyuan Oilfield.
