SSHG底片特性曲线制作的注记

Notes on the Making of the Characteristic Curve of An SSHG Plate

本文将介绍在计算机上制作SSHG底片特性曲线的方法,并针对1991年4月12日无黑子耀斑光谱的底片特性曲线的制作,阐述几个易误解的物理问题。本文还将给出SSHG底片特性曲线的一个经验公式。

In this paper,a method is briefly introduced for making the characteristic curve of an SSHG plate by using a computer.As an example,the characteristic curve of the spectral plate of the spotless flare of 1991 April 12 is made successfully,and an empirical formula is given for describing the characteristic curve of an SSHG plat.Some physical problems on the characteristic curve easy to be misunderstood are also discussed.
