本文对1963年武仙座新星的一次“氮闪”光谱作了分光光度测量.表2—表4列出发射带等值宽度、相对强度和连续谱能量分布的测量结果.分析测量结果发现“氮闪”谱同“氮闪”前光谱相比有如下特征:(1)“氮闪”时,容许跃迁的谱带强度高电离的比低电离的明显增强;禁戒跃迁的谱带强度高电离的比低电离的明显减弱.(2)“氮闪”耐,连续谱的强度相对发射带有所增强;并且连续谱的蓝区比红区增强得厉害,即色温度增加.根据上述“氮闪”谱的特征,我们对“氮闪”现象的解释提出如下意见:(1)“氮闪”的主要特征,NⅢ 4640 波长处谱带的增强与变漫乃是由于 NⅢ 4640、CⅢ4647和 CⅣ 4659等高电离谱带的加强与重叠的结果.(2)“氮闪”现象的产生是由于“氮闪”前新星发生了一次小的爆发.随后,这个被抛射的小壳层逐渐膨胀和稀薄,于是在某个时候出现了“氮闪”现象.

This apparatus is a multifunction spectrum testing set-up, which suits to measure for infrared detectors the wide range spectral sensitivity and also the distribution of spectral energy. The whole set-up consists of the optical system, the electrical signal processing system and the automatic data logging set-up. The wavelenoth range that the spectrum responses equals 1—50μm, the ealibrated wavelength accuracy within 1—10μm range being±0.1μm, and the repetition of therelative spectral sensitivity distribution being 2%. The influence on the measurement could be overcome in connection with the energy loss caused by the selection of radiant source spectral distribution, thanks to the use of reference detector method and the phase-locked technology, and also the noise has been effectively supressed and the signal to noise ratlo of system testing is raised, making the noise equivalent power of the set-up reach NEP<7×10~(-11)WHZ1/2.

本装置是一多功能光谱测试装置,适用于对红外探测器作宽范围光谱灵敏度的测量,以及红外光源光谱能量分布测量。整个装置由光学系统、电信号处理系统和数据自动记录系统组成。光谱响应的波长范围为1~50μm,在1~10μm波长范围内已校正的波长准确度为±0.1μm,其相对光谱灵敏度分布的重复性为2%。由于采用参比探测器方法组成双光路分光系统,以及锁相放大技术,消除了辐射源光谱分布的选择性和反射及吸收形成的能量损失对测量带来的影响。同时有效地抑制了噪声,提高了系统测试的信噪比,使装置的噪声等效功率达到NEP<7×10~(-11)W/HZ1/2。
