Lactated Ringer's or 7.5% NaCl+6% dextran 70 was given for resuscitation 6h postburn.The volumes and rates of fluid infusion were controlled basically on the urinary output of 1.0ml*kg-1*h-1 and cardiac output of 70%～80% of preburn values.The volume load,+dp/dtmax,-dp/dtmax,CI,DO2 and VO2 were obtained to evaluate the effect of HSD resuscitation. Results The resuscitated volume of HSD was 30.56% less during first 24h postburn and 59.50% less at 4h after resuscitation than LR's.

The result showed that the influence of temperature and RH on average price and rate of first class of flue-cured tobacco was similar, which showed a trend of parabola curve with temperature or RH increasing. The maximum value of average price occur at 38.0℃ and 87.0%, the maximum value of the rate of first class occur at 37.6℃ and 86.5%. The result also showed that when the temperature or RH was in the range of 37.5℃ to 38.0℃ or 85.0% to 88.0%, psychrometric difference was 1.5~2.0℃, the average price and rate of first class would exceed 10 yuan per kg and 40% respectively.
