为使计算机“不断线”,我院在84级《电路》实验课中,应用CASIO、PB-700微型计算机进行实验数据处理。收到了良好的反映和效果:1.明显的提高了数据处理的质量和精度。如图1为用PB-700绘制的“非正弦电路研究”的实验曲线,既正确又美观。2.便于比较、检查,利于培养学员分析问题的能力。“功率因数的提高”实验,微机按给定的参数与物理量绘制一条cosφ=f(c)的理论曲线,并直接打印出原要求计算的cosφ值(如图2)。从中,就可以直观地根据两条曲线进行分析、讨论(如误差原因分析、曲线形状的讨论等)以开拓思路。
In order to make the computer “keep abreast of”, our hospital in 84 “circuit” experimental class, the application of CASIO, PB-700 microcomputer for experimental data processing. Received a good reflection and effect: 1. Significantly improve the quality and accuracy of data processing. Figure 1 shows the experimental curve of “non-sinusoidal circuit” drawn by PB-700, which is both correct and beautiful. 2. Easy to compare, check, help students develop the ability to analyze the problem. “Power Factor Improvement” experiments, the computer according to the given parameters and physical quantities to draw a cosφ = f (c) theoretical curve, and directly print out the original required cosφ value (Figure 2). From here, you can intuitively analyze according to the two curves, discuss (such as error analysis, the discussion of the shape of the curve, etc.) to explore ideas.
