普朗克常量测定的误差分析

The Error Analysis in Measuring Planck Constant

根据用反向遏止电压法测量普朗克常量的实验原理 ,讨论了暗电流、本底电流、反向电流对实验结果影响的大小 ,并对遏止电压的几种不同取法进行了分析 ,总结出比现行教材和文献中采用的更好的方法 ,在一定程度上修正了遏止电压 ,得到了较理想的实验结果 .

According to the experimental principle of using inverted check voltage method to measure Planck constant, we discuss the effects of the dark electrical current, background electrical current and the inverted electrical current to the experimental result. We have analyzed several different methods to choose the check voltage and summarized the better method than used in textbooks and references. We have revised the check voltage to some extent and obtained a satisfactory experimental result.
