-
摘要: 探讨了科技论文文摘的作用与构成要素,分析了文摘的性质和特点,阐明了文摘写作中应注意的问题,给出了文摘的范例.Abstract: Modification method of terpolymer of vinyl acetate with acrylic-n-butyl methacrylate was introduced,and effects of comonomer,temperature and emulsifiers were discussed. Experimental results show that terpolymer emulsion modified has higher shear strength and ability to resist water and freeze.
