A novel kinetic mechanism of esterification reaction of 1-hexanoic acid with 1-butanol, catalyzed by lipase, was studied in water-in-oil microemulsions. The microemulsions were formed by alkyl polyglucoside C10G1.54/1-butanol / cyclohexane/phosphate buffer solution. The result shows that when the ratio of mol concentration of 1-butanol to 1-hexanoic acid is about 3.0, the initial rate V0 get the maximum values. This phenomenon was explained by the modified fishlike phase diagrams.

三年级是承上启下的过渡阶段,是作文的起步阶段。绘本以其丰富的读写资源,成为辅助三年级起步作文的重要材料。在三年级的语文教学实践中,我发现绘本教学可以为学生的习作架起一座起步的桥梁。一、创意读,激发表达欲望  怎么读绘本,是有讲究的,“深入”“用心”地创意解读绘本,运用多种形式和手段帮助孩子融进绘本,就能激发他们的表达欲望。  1.猜测读。“猜”,是儿童天生具备的一种思维能力,可以激发他们的阅读兴趣
