| Abstract: | In this article, the influences on the spectral line's half-angle width and chromatic resolving power are analyzed when the width of the slit resouce in the prism spectrum instrument can not be ignored and the formula of chromatic resolving power is revised. Meanwhile a reference principle of how to choose the width of the slit resource in laboratory is intrduced, and the relationship in a prism spctrum instrument between the width of slit resouce and the chromatic resolving power is showed by practical datum. |
