| 摘 要： | 用500MeV/u^56Fe,650MeV/u^40Ar,600MeV/u^28Si和180MeV/u^4He对固体气泡损伤探测器（T－12型）进行了实验研究，实验结果表明，固体气泡损伤探测器的阈特性可用临界能量损失率表征，在一般条件下，限定能量损失率在不同重离子产生径迹时不具有相同的临界值，因此，不能作为径迹形成的判据。 |
| 关 键 词： | 固体气泡损伤探测器 阈起源 临界能量损失率 限定能量损失率 |

| Abstract: | Experimental studies have been carried out with 500MeV/u \ 56 Fe, 650MeV/u \ 40 Ar, 600MeV/u \ 28 Si and 180MeV/u \ 4He for T-12 type bubble detectors. The studies show that threshold property of bubble detectors can be expressed by critical rate of energy loss. Contrarily, restricted energy loss rate can not be the criterion of track formation in bubble detectors under ordinary condition for the reason that different heavy ions create tracks at different critical values of the restricted energy loss rate. |
| Keywords: | Bubble detector Origin of threshold Critical rate of energy loss Restricted energy loss |
