摘要: In this review, various cryogenic refrigeration methods to obtain temperatures extending down the milliKelvin/microKelvin range are described after first explaining concepts of a “thermodynamically ideal cycle” and “figure merit”. The cycles compared with each other. Data about some commercially available refrigerators/cryogenerators have also been included in review.
