摘要
运用Matlab可视化语言编程,绘制了表征普朗克辐射公式物理意义的图形.通过对该图形曲线的深入分析,直观地阐明了维恩位移定律和斯忒藩-玻尔兹曼定律与普朗克辐射公式的关系及这两个定律的物理含义;又从图形出发,采用数值计算方法,求解得到工程实践中所关心的波段辐射出射度参数,以及光电探测器优化选择的策略.
With the visual programming language of Matlab, the curves which present the physical meanings of Planck radiation formula were drawn. Through deep analysis of the curves, we visually clarified the relations of the Planck radiation formula to Wien displacement law and Stefan-Boltzmann law. Furthermore, the hand radiant exitance parameters, which are very useful in engineering applications, have been obtained by numerical calculation in terms of curves. The choice strategy of photoelectric detector systems has also been optimized.
