辐射功率是辐射物理量中最基本的一个物理量。在以往的实验中,采用的是传统办法——传递法。此法有许多弊病,如麻烦、测量结果与时间条件有关等。 电校准辐射功率测量很早已被人们所认识,近年发展很快,并已被某些国家定为辐射测量标准。在近代物理教学中,电校法测量辐射功率不但能完成传递法的测量任务,节省时间,更重要的是在实验中能引导学生考虑条件因素对测量的影响,重视误差分析,并能启发学生注意将近代科学成就运用到科学试验中去。 Radiant power is the most fundamental physical quantity of radiation. In the past experiments, using the traditional method - transfer method. This method has many drawbacks, such as trouble, the measurement results and time conditions and so on. Electricity calibration Radiated power measurement has long been recognized by people and has developed rapidly in recent years and has been set by some countries as a radiometric standard. In modern physics teaching, the measurement of radiation power by electric school method can not only accomplish the measurement task of transmission method, save time, but more importantly, it can guide students to consider the influence of condition factors on the measurement in experiment and attach importance to error analysis and inspire students Pay attention to using modern scientific achievements in scientific experiments.
