摘要:

Based on observations of thermoelectric power and the Wiedemann‐Franz ratio &lgr;/&kgr;, a compensated radiation thermopile has been built and operated in a vacuum at low temperatures, which shows a more than tenfold increase in sensitivity when operated at the temperature of liquid oxygen, as compared to operation at 25°C.
