         Cepheid variables CY Aqr and BE Mon were observed at the Purple Mountain Observatory with a photoelectric photometer during December 1959 and the first two months of 1960.The observations of CY Aqr (Table 1) made on four nights provide sufficient data for plotting five complete light curves (Fig.1) of this variable.The phase of these observations has been computed with Lange and Nekrasova's formula.We noticed that the maxima of the plotted curves do not fall on the zero phase,but show a shift of about...
            用紫金山天文台的60厘米反光望远镜和1P21光电倍增管所构成的光电光度计,我们在1959年底和1960年初,对 CY Aqr 及 BE Mon 进行了测光观测.得到 CY Aqr 的五条完整的光变曲线.我们采用了从1934年到现在的29个观测所得的极大历元来和公式计算的相比较.若不承认历元有跃迁的可能,那末任何线性公式,都难以满足这些观测数据的要求.我们按周期随时缩短的假设,得出下列比较满意的公式:Max⊙=I.D.2427658.4079十0~d.061038576E—(0~d.742×10~(-12))E~2.用前后将近两个月观测 BE Mon 所获得的数据,我们得到了这颗造父变星的光变曲线.变星总表引用所定0~d.421的周期是不正确的.根据我们观测所得到的周期是2~d.704.按这周期来整理于1935年所完成的目视观测,我们也得出了一个很象样的光变曲线.

         A zenith-telescope,ZTL-180,has been mounted at the Tientsin International Lati- tude Station in the Summer of 1958. Observations of latitude variations have been made since January 1959.During the first three years 10203 star pairs were observed on 702 nights. The results of the determination of the declination corrections for each group and cach pair and the variations of latitude are given.Preliminary values of the polar mo- tion were calculated with our latitude variations by A.J.Orlov's method.
            天津纬度站于1958年夏安装了一架口径180毫米,焦距2340毫米的目视天顶仪.仪器位于北纬39°8′纬线上.1959年1月开始了正式的纬度观测.三年内,在702个晴夜中共得10203个纬度值.本文利用这些观测,定出了所用星对的赤纬改正,求出津站三年间的纬度变化以及周年非极性变化,并利用纬度变化结果按奥洛夫法对地极坐标作出了试算结果.
