Stellar atmospheric parameters of 525 variables were determined, while spectral types were obtained for all samples. In the paper, those spectroscopic data are catalogued. We detect a group of 131 unusual and cool variable stars (UCVs) that are distinguished from the normal $\\delta$ Scuti stars (NDSTs). On the H-R diagram and the $\\log g-T$ diagram, the UCVs are far beyond the red edge of pulsational instability trip. Their effective temperatures are lower than 6700\\,K with periods in the range from 0.09 to 0.22\\,days. ND","authors_text":"J.J. He, J. Zhang, L.J. Li, L.Y. Zhu, S.B. Qian, Z.T.
