Learning society may be abstracted as social innovation system , life - long education system and social runing system . these three systems constitute learning force , and science and technology promote the formation of learning society by acting on the learning force . based on the analysises of models , the fourth part analyses the enlightenment the dynamics mechanism of science and technology promoting the formation of learning society has on humankind ' s development , and points out that learning society is a necessary result of the development of science and technology , so , mankind should pay great attention to science , technology and education , and pay great attention to coordinated development of society and science and technology when building learning society , as a result , ma 科技的推动，终身教育、终身学习的发展使学习型组织的出现成为必然；论文的第三部分建构学习力模型和科技动力模型，学习型社会可以抽象为社会创新体系，终身教育体系和社会运行体系，这三个体系构成社会的学习力，科技通过对学习力的作用推动学习型社会的形成；论文的第四部分在模型分析的基础上，分析了推动学习型社会形成的科技动力机制对人类发展的启示，指出学习型社会是科技发展的必然结果，人类应该重视科技和教育，在创建学习型社会时要注意科技发展和社会发展的同步，使人类走上科技与社会协调发展的道路。
( 3 ) volume shrinkage of composite decreases greatly with wpu increasing , even can arrive a negative number , but thermal stability is still good . ( 4 ) toughening mechanism is that : the formation of high molecular linear amino formate construct is the toughening reason ; hydroxyl - terminated pu - prepolymer and pf react to produce chemical bond effect which participate cure ; carboxyl - terminated pu - prepolymer and pf form semi - ipn which make toughened pf occur maximum （ 4 ）通过红外光谱对pf / pu共混物分子结构进行的定性分析、以及扫描电镜对冲击断面形貌进行的分析，可证明聚氨酯预聚物增韧酚醛树脂的机理是：两个体系都是由于高分子量的线形氨基甲酸酯结构而增韧；端羟基pu与pf在共固化中产生化学键效应，参与pf的固化；而端羧基pu则与pf形成半互穿网络而增韧。
