The diffusion current is measured using transistor and digital ammeter instead of operational amplifiers, and the Boltzmann constant is obtained accurately. 在不使用运算放大器的情况下,直接利用晶体三极管与数字式电流表测出扩散电流,可以得到较为准确的玻尔兹曼常量。
Based on the relationship between the diffusion current and voltage of PN junction, the Boltzmann's constant is measured with high accuracy. 运用半导体的PN结扩散电流与电压关系特性,精确地测量了玻尔兹曼常数。
