为了满足热功率为10μW水平的α和β放射源活度校准需要,研制了1台活度微量热计测量装置。该装置采用半导体测温元件组合(Bi2Te3+Sb2Te3p型与Bi2Te3+Bi2Se3n型)作为测温元件,采用等温
In order to meet the need of calibrating the activity of α and β radioactive sources with a heating power of 10μW, a measuring device for activity microcalorimeter was developed. The device uses a combination of semiconductor temperature measuring element (Bi2Te3 + Sb2Te3p type and Bi2Te3 + Bi2Se3n type) as a temperature measuring element, using isothermal
