【摘要】：太阳半径是指从太阳球心到光球层外边界的距离。测量太阳半径历史悠久,系统性测量始于19世纪,其标准值为959.63〃。主要有以下几种测量方法:(1)子午圈测量;(2)日食和水星凌日;(3)望远镜漂移扫描技术;(4)等高方法;(5)卫星角距离测量。对于太阳半径的研究,主要集中在以下三类观点:一是认为太阳半径在缩小;二是认为太阳半径基本没有变化;三是认为太阳半径变化与一些太阳活动指数有关联,并具有自身的运动规律。太阳半径是否变化,如何变化,目前尚无定论。首先介绍了太阳半径,回顾了太阳半径的观测方法;接着介绍了目前太阳半径的主要研究观点;最后对将来的研究提出一些看法。
[Abstract]:The radius of the sun is from the center to the solar photosphere outside the boundary distance. The measurement of the solar radius has a long history. The systematic measurement began in nineteenth Century and its standard value is 959.63 ". The main measurement methods as follows: (1) meridian measurement; (2) the solar eclipse and transit of mercury; (3) telescope drift scanning technology; (4) high; (5) satellite angular distance measurement. For the study of solar radius, there are mainly three kinds of viewpoints: one is that the solar radius is decreasing; the two is that the solar radius is basically unchanged; three, we believe that the solar radius variation is related to some solar activity indices and has its own motion rule. It is not conclusive whether the radius of the sun is changing and how it changes. First, the solar radius is introduced, and the observation method of solar radius is reviewed. Then, the main research viewpoints of the current solar radius are introduced. Finally, some views on future research are presented.

【正文快照】： 太阳是原始星云由于引力坍缩形成的,太阳形成后进入主序星阶段。图1简要展示了太阳的演化过程,太阳从形成到目前有46亿年历史。太阳进入主序星到红巨星阶段,半径和光度随时间的增长而变大。太阳不像岩石类行星那样有一个具体明确的边界。太阳半径是指从太阳球心到光球层外边界
