The results showed that: the charging method had significant influence on deep cycling VRLA batteries;the constant-voltage charging method tended to long-term undercharge the batteries;the failure cause of constant-current charging batteries was that the active material would be soften and shed; the VRLA battery's serveice life would be improved by using pulse-charging method.

结果表明：1、充电制度对深循环VRLA电池的寿命有着重要的影响；2、恒压充电方法容易导致电池长期充电不足，从而发生硫酸盐化；3、恒流充电的电池失效原因是正极板铅膏发生软化、脱落；4、脉冲充电的方法可使深循环VRLA电池寿命提高。

Measure the area of burn with vegetable parchment every 5d for calculation of healing rate. Select 3 rats from each group 6h, 9d and 25d after burn respectively for pathological examination of burn surface.

每5d用透明硫酸纸描绘烫伤皮肤面积，并称重，计算烫伤皮肤愈合率；烫伤后6h、9d和25d，各组随机选取3只大鼠，对其烫伤创面进行病理学检查。

Veratrum aldehyde synthesis of many drugs intermediates, methyl aldehyde method for raw materials in Champlain, after dimethyl sulfate methylation available to 20% sodium hydroxide as the solvent, 10-11 in the PH value of the under the conditions of synthesis; microwave irradiation is the use of microwave radiation heating to replace the traditional approach to synthesis of a product of methylation reactions, this method does not require solvents, and less by-products, but still need to use 15% sodium hydroxide to adjust pH.

藜芦醛是许多药物合成的中间体，甲基化法以香兰醛为原料，经过硫酸二甲酯甲基化可得，以20%氢氧化钠为溶剂，在PH值为10-11的条件下合成；微波辐射法是利用微波辐射代替传统加热方式进行甲基化反应合成产物，这种方法不需要溶剂，并且副产物少，但仍需要用15%氢氧化钠来调节酸碱度。
