圣佩德罗大范围变异性调查会议：一些结论性意见
San Pedro Meeting on Wide Field Variability Surveys: Some Concluding Comments
摘要：
这是第22届洛斯阿拉莫斯恒星脉动会议关于宽场变率调查的闭幕式发言的书面版本。报告对会议上提出的一些问题作了评论。这些问题包括需要注意光度标准化（特别是在红外线）和在使用视差（和其他距离测定方法）时存在的统计偏差问题。本文还介绍了利用脉动变星研究银河系结构的一些主要进展。该文件包括一个澄清的经典造父变星和RR天琴座恒星在银河系内部和凸起的明显相互矛盾的结果。强调理解变星，特别是AGB变星和RCB星的非周期现象的重要性，特别是它与质量损失的相关性，其中脉动可能只起次要作用。
英文摘要：
This is a written version of the closing talk at the 22nd Los Alamos Stellar pulsation conference on wide field variability surveys. It comments on some of the issues which arise from the meeting. These include the need for attention to photometric standardization (especially in the infrared) and the somewhat controversial problem of statistical bias in the use of parallaxes (and other methods of distance determination). Some major advances in the use of pulsating variables to study Galactic structure are mentioned. The paper includes a clarification of apparently conflicting results from classical Cepheids and RR Lyrae stars in the inner Galaxy and bulge. The importance of understanding non-periodic phenomena in variable stars,particularly AGB variables and RCB stars is stressed, especially for its relevance to mass-loss, in which pulsation may only play a minor role.
