摘要
本文介绍比色法测定糖化酶活力新方法。糖化酶水解淀粉产生葡萄糖,生成的葡萄糖与3,5—二硝基水杨酸钠盐(DNS)作用,发生颜色改变,颜色变化的多少与葡萄糖含量成正比。因此糖化酶水解液与DNS反应后,在550nm处测定吸光度,由吸光度看出葡萄糖含量,并计算出糖化酶的活力。比色法简单、快速,准确度和标准法相当,是仪器分析测定糖化酶活力的理想方法。
With the combine of the computer’s technology and the communications technology,there have been a progress on the computer network’s technology.The essay provides the structure of computer networks both in hardware and software,at the same time it takes a comprehensive discuss on the development trend and the application of network’s technology.
