文摘	用脉冲可调谐光参量振荡器作光源，使用光程长达1 km的8 m长吸收池，采用分时复用的单探测器探测方法，组成测量系统，测量了一系列高分辩率的模拟和实际大气的吸收光谱。系统的灵敏度为0.5 * 10~(-6) cm~(-1)，分辩率为0.02 cm~(-1)。1.315 μm附近实际大气的吸收光谱与HITRAN96模拟结果比较，强线符合得很好。水汽光谱的大多数强线的分子线强度相对误差在10%以下。
其他语种文摘	The high-resolution absorption spectra of real and simulated atmosphere were recorded by using an experimental system, which includes a tunable pulsed OPO, an 8 m base-length white cell with optical length of 1 km, and a time-division multiplexing detector system. The sensitivity is 0.5 * 10~(-6) cm~(-1) and resolving power is 0.02 cm~(-1). The high-resolution absorption spectra of real atmosphere near 1.315 μm have been measured and compared with the simulated spectra according to HITRAN 96 database. The strong lines of water vapor molecule fit very well and the relative errors of molecular line intensity of the most strong lines are less than 10%.
