    • 本次的研究，包含GP And, BP Peg, 和 CY Aqr等三顆變星最大亮度值的新觀測。並對每一顆變星些微的週期變化作光度曲線的分析。
    較大震幅類型的盾牌座型變星GP And，脈動週期變化由O-C圖所導出新公式為Cnew ＝ 2433861.5146＋0.0786829154 × E＋4.6 × 10-13 × E2

    討論矮造父型變星BP Peg的光度觀測。由O-C圖推算出新的基調週期為0.10954410天。
    而較長週期變化的變星 CY Aqr透過O-C圖的分析所得的週期為0.061038323天。CY Aqr受光與時間影響後的雙星參數值變化, 由CY Aqr的O-C圖推得K = 0.006, Porb = 49.8 years, e = 0.7, ω = -38.9 and 。

    In this work, the observations present new times of maximum light with three variable stars in this investigation include GP And, BP Peg, and CY Aqr. The analysis of the light curve for each of the variables were showed small period changes.
    The pulsation period variability of the high-amplitude delta Scuti star GP And in the O-C curve is inferred new formula 
    Photometric observations of the dwarf Cepheid BP Peg are discussed. The new derived in the O-C curve for the fundamental period is 0.10954410d.
    With the analysis of O-C diagram showed the long-term period change of CY Aqr for period is 0.061038323d. And the binary constant of CY Aqr to the light-time effect procedure could be inference, K = 0.006, Porb = 49.8 years, e = 0.7, ω= -38.9 and  to fit CY Aqr’s O-C diagram.
