<正>利用石蜡切片法观察南京椴花芽分化过程。结果表明：南京椴越冬体眠芽为混合芽，萌发后叶腋处形成花芽。花芽分化时期为当年3月底至5月初，历时35～40d，具有分化时间短、速度快的特点。花芽分化包括花序分化和小花分化两个过程，可划分为花芽分化始期、花序原基分化期、小花原基分化期、花萼原基分化期、花瓣原基分化期、雄蕊原基分化期、雌蕊原基分化期等7个时期。

Veneered maple furniture panels were sanded and sprayed by two pieces of water-borne sealer. Wet coating was dried by the hot air using process parameters. Adhesion of dried coatings was tested with the pulling method. The results showed that humidity of hot air was very important, but its temperature has minor effects on adhesion of coatings at a certain extent. It was seen that when 35℃ hot air with 50% humidity was firstly used to dry the sealer and the second was 35℃ hot air with 70% humidity, the beater adhesion of the sealer was obtained.
