【摘要】 提出了一种封管后的热处理工艺，应用这种工艺，可提高红外变像管的低照度鉴别率，降低等效背景照度，并使管子内的真空状态得到改善，从而使光电阴极的稳定性得到提高，增加了管子的可靠性。更多还原

【Abstract】 A thermal processing technique is introduce, by which the low illuminance resolution can be increased and the equivalent equivalent illuminance reduced. As the vaccum is highter, the stability of photocathode and the reliability of the tube can be en hanced.更多还原
