A germanium bolometer cooled to 0.37 K by liquid (3)He is described. This detector has a NEP of about 3 x 10(-14) W /Hz(1/2) which is more than three decades greater sensitivity than the Golay cell. The factors that determine the sensitivity of the detector are discussed.
描述了一种用液氦（3）冷却到0.37K的锗测辐射热计。该探测器的等效噪声功率约为3×10^(-14)W/Hz^(1/2)，其灵敏度比戈莱盒高三个数量级以上。讨论了决定探测器灵敏度的因素。
