摘　　要：在建立太阳全日面黑子照相观测系统的基础上对黑子观测资料进行了处理,给出黑子观测的重要数据及相关参数,为太阳物理学家研究太阳活动规律提供和积累最基本的第一手数据。这些数据包括:太阳黑子相对数,南北半球太阳黑子的坐标和黑子群数,太阳黑子的圆面积和球面积等。编写了一个程序,对每天的太阳黑子观测资料进行处理,给出以上物理参数,彻底改变了手工描绘黑子和计算黑子参数的传统方法,同时也提高了黑子资料处理的精度和效率。In this paper we present a data-reduction approach and related software for processing data of sunspots obtained from a photographic full-disk solar observation system established by us.When applied to data from our system the approach and software yield fundamental data and parameter values of sunspots, which can serve as the first-hand data to be accumulated and used by solar physicists to study underlying mechanisms of solar activities.The results of our data reduction include those of the relative sunspot numbers. sunspot-group numbers, sunspot locations, sunspot circular areas, sunspot surface areas, sunspot total areas, sunspot classifications, and distances from sunspots （ or sunspot groups） to the solar center.As part of our data reduction we have incorporated a calculation program, which makes it possible to rapidly process daily sunspot data and give values of the mentioned parameters.Our approach may thus completely change the traditional method of manually handling photographic sunspot data, and greatly improve efficiencies of sunspot observation/data processing.It is still necessary for an observer to have certain observational experience and technical skill to use our approach, especially in grouping sunspots and evaluating group numbers.
