定性分析实验,所需鉴定的阴阳离子近三十种,而离子的性质各异,反应条件复杂,操作手续繁琐。用微型计算机模拟分析实验,可以促进学生学习的主动性和热情,增强学习的兴趣,从而达到提高教学质量的目的。 IBM机当前在我国普遍采用,在该机的BASIC语言中,与图形有关的语句很多。其中GET和PUT语句有使图象在屏幕上高速移动的功能,应用它可以收到动画效果,为计算机模拟化学实验提供了有利条件。
Qualitative analysis of experiments, the identification of nearly 30 kinds of anion and cation, and the nature of different ions, the reaction conditions are complex, tedious procedures. Using microcomputer simulation analysis experiment, can promote students’ initiative and enthusiasm, enhance the interest of learning, so as to achieve the purpose of improving teaching quality. IBM machine is currently widely used in our country, in the plane of the BASIC language, a lot of statements and graphics. The GET and PUT statements have the function of moving the image on the screen at a high speed. The application of the GET and PUT statements can receive the animation effect and provide favorable conditions for the computer simulation of the chemical experiment.
