We have made infrared spectroscopic observations of a number of high redshift galaxies and quasars with a newly developed infrared spectrograph called OHS (OH-airglow suppressor spectrograph) with appreciably enhanced detectivity by eliminating strong OH airglow lines in the telluric upper atmosphere. The results of spectroscopic observations accomplished in the course of this research program have been offerring crucial information in investigating formation and carly evolution of galaxies and quasars, as we have intended to do as a major purpose of the observational research.Individual target objects and their scientific results are briefly summarized as case studies ; i) the nature of an ultra-luminous IRAS galaxy : FSC10214+4724 has been studied, suggesting an obscured AGN of the Seyfert2 type, probably magnified by gravitational lensing, ii) The extremely red galaxy : Hawaii 167 has been shown to have characteristics of both a very young quasar and a post-starburst galaxy, iii) The unusual spectral signatures of a strong damped Lyman-alpha quasar : 0201+113 has been obtained, quantifying the content of dust and therefore the metalicity of the intervening galaxy at a high redshift of 3.39, and, iv) The origin of an extraordinary emission line galaxy : 4C40.36 has been investigated by a synthetic model galaxy to know evolutionaru stage of the galaxy.

我们用一台新研制的红外光谱仪OHS（OH气辉抑制谱仪）对一些高红移星系和类星体进行了红外光谱观测。在本研究计划中完成的光谱观测结果为研究星系和类星体的形成和演化提供了重要的信息，这是我们观测研究的一个主要目的。作为案例研究，简要地总结了单个目标天体及其科学结果; i）超亮IRAS星系的性质：FSC 10214 +4724已经被研究过了，这表明一个被遮蔽的赛弗特2型活动星系核，可能被引力透镜放大了，ii）极红星系：夏威夷167已经被证明具有非常年轻的类星体和星暴后星系的特征，iii）强阻尼莱曼α类星体的不寻常光谱特征：0201+113的测量结果，从而定量了中间星系在3.39高红移处的尘埃含量和金属度。iv）用合成模型星系研究了一个异常发射线星系4C40.36的起源，以了解该星系的演化阶段。
