| 摘 要： | 我们通过对国产ＢＷ—１４００型真空钨带灯的稳定性判据进行研究，发现通过钨带灯的电流达到稳定的时间很短（小于５分钟），而钨带灯的灯电阻需要经过２０分钟后才能达到稳定，因此，用电流稳定性作为钨带灯的热平衡判据是不够的，更可靠的判据还应看灯电阻是否达到平衡。

| Abstract: | The criterion of stability for BW-1400 vacuum tungsten lampis studied. Lamp current needs very short time to be stable (less than5 min), but the lamp resistance needs longer time (about 20 min). Lampcurrent stability is not enough to judge whether or not the tungsten lampreaches thermal equilibrium. The more suffici ent criterion is lamp resi stance. |
