The average level of the soil available potassium was 119.96 mg/kg, which decreased 18.94 mg/kg and 1.05 mg/kg one year averagely. But the decreasing trend alleviated in recent years. There were 39.5 kg/hm^2 nitrogen and 30.9 kg/hm^2 phosphorus (P2O5) more than needed averagely, and 150.0 kg/hm^2 potassium (K2O) in deficiency. Though the fertilizer application was high and the rate of fertilizer was 647.96 kg/hm^2 in nutrient, the ratio of organic to inorganic was still unreasonable. The ratio of the chemical fertilizer nitrogen phosphorus (P2O5) and potassium (K2O) was 1:0.42:0.14. The nitrogen application was enough and even higher than that was needed. The phosphorus was proper elementarily and potassium was in deficiency. The yield of wheat which was the main crop increased slightly and that of other autumn harvest crops was stable.

土壤速效钾7年平均值119.96 mg/kg，比第二次土壤普查时下降了18.94 mg/kg，平均每年以1.05 mg/kg的速度下降，但近年来下降趋势变缓；养分平衡中氮素平均盈余39.5 kg/hm^2，磷素(P2O5)盈余30.9 kg/hm^2，钾素(K2O)亏缺150.0 kg/hm2；全省施肥水平较高，每公顷总施肥量折纯养分647.96 kg，但有机无机比仍不合理，化肥氮、磷、钾投入比例1：0.42：0.17，氮肥充足，部分地区用量偏高，磷肥基本合理，钾肥不足；主要农作物小麦产量略有上升，其它主要秋收作物产量基本稳定。

Results Of the 270 snorers,there were 247 SAHS patients.Their AHI,ODI4,MAI and SL were (43±27)/h,(44±23)/h,(29±16)/h and (12±17) min,respectively.

During the moisture adsorption process from oven-dry state to the equilibrium state in 20℃, 60％RH environment, the activation enthalpy of adsorbed water during reorientation increases linearly with adsorption time.

从绝干状态→20℃，60％RH平衡态的水分吸着过程中，吸着水分子在回转取向过程中的活化焓随着吸湿时间呈线性增加，这说明一个吸着水分子与周围木材吸着点之间的氢键结合数的平均值随着吸湿过程的进行逐渐增多，直至达到平衡状态。

We evaluated15 children with negative clinical findings and a normal electroencephalogram as part of their follow-up for prior episodes of epilepsy,recording the BIS and EEG in a waking state, in the variousstages of sleep and on reawaking. For each stage, the mean value,the standard deviation, and the range of BIS values were calculated.

笔者选择了15名既往有癫痫发作史的儿童作随访，当前临床指标阴性且脑电图正常，记录清醒状态、各个睡眠阶段以及再醒时的 BIS 和 EEG ，计算每个阶段 BIS 的范围值、平均值和标准差。
