Ninteen spring soybean varieties spread from N 22.7°to N 50.2°were sowed on 4 dates in 2 years,respectively.The objective of present research is to study the effect of sowing dates on ecological traits of spring soybean.The results showed that plant heights and nods of main stem decreased as sowing date delayed and the degree of delayed amount increased gradually.Among all mature types,early-middle varieties showed the lowest plant height and nods of main stem.There were significant variations in aboveground biological weight,dry stem weight,pod shell weight,seed weight,among different maturity varieties.Effect of sowing date varied according to maturity types.Under delayed sowing date(sowing at June 11 and July 1) the ratio of seed to aboveground biological weight(economical coefficient) increased for early and middle verieties early.Number of pod per plant,number of seed per unite area and 100-seed weight were increased for ueltra-early varieties.

Objective To investigate the efficacy and safety of flurbiprofen axefil combined with sufentanil on postoperative pain in elderly patients and to explore the optimizing medication.Methods Sixty patients(ASA Ⅰor Ⅱ) aged 65-85 yrs undergoing elective upper abdominal surgery were randomly divided into four groups(n =15 each).In A group flurbiprofen axefil 50 mg was given intravenausty after the surgery,with sufentanil 100 μg in PCA pump.In B group flurbiprofen axefil 150 mg+ sufentanil 75 μg was added in PCA.In C group flurbiprofen axefil 50 mg was given intravenausty with flurbiprofen axefil 150 mg + sufentanil 50 μg in PCA.In D group sufentanil 100 μg was added in PCA.VAS score,Ramsay sedation score,the cumulative sufentanil consumption,the number of atempts,number of successful deliveries and side-effects were evaluated at 0,4,8,12 and 24 h after the surgery.The awakening time and extubation time was also recorded.Results In B and D groups the VAS score was significantly higher than that in A and C groups at 0,4,8h after the surgery(P0.05).In A and D groups Ramsay score was significantly higher than that in B or C group at 4,8,12h after the surgery(P0.05).Number of attempts and the number of successful deliveries was significantly higher in B,D groups(P0.05).The consumption of sufentanil was significantly lower in group C than that in A,B or D group(P0.05).Conclusion PCIA with flurbiprofen axetil 1.50 mg/ml combined with sufentanil 0.50 μg/ml injection could be a safe and effective method for postoperative analgesia in elderly patients.

The environmental pollution of textile industry mainly comes from liquid waste,waste gas,discard material and noise.The above four factors were analysed and relative measures to take were put forward.
