摘要

介绍了BVRI CCD对脉动星SZ Lyn的新观测结果。利用傅里叶变换技术对光曲线进行分析，确定了一个新的周期。提出了一种新的星历表，该星历表基于最近的极大值。在过去的40年里收集的光度数据被用来确定脉动和轨道元素，因为SZ Lyncis是一个双星系统的成员。结果与之前的研究结果进行了比较。

SZ Lyn: New BVRI CCD observations and improved pulsational and orbital elements

New BVRI CCD observations of the pulsating star SZ Lyn are presented. The light curves are analyzed using Fourier transform techniques and a new period is determined. A new ephemeris, based on recent times of maxima, is proposed. The photometric data collected over the last 40 years are used to determine the pulsational and orbital elements, since SZ Lyncis is a member of a binary system. The results are compared with those found in previous studies.
