摘要
本文应用自然光作为光源,应用微电流测量放大器、微机化X-Y记录仪软件,对光电管上的电压和电流值进行采集和处理,并用Origin7.5统计软件,拟合出光电管电压和电流按照一定规律变化的关系式,拓宽了物理实验软件的使用范围,拓宽了软件研究范围。
By using natural light as light source, using microeurrent instrumentation amplifier and the computer- ized X - Y recorders software,it collected and processed numbers of voltage and current of photoelectric tube. By Origin 7.5 statistical software,relational expressions in accordance with the certain law change are fitted. It en- larged the scope of the use of the physics experiment software and the scope of sutdy the use of software.
