本文用数学分析方法建立直线的概念,将X射线曝光曲线简单归纳为一组斜率(b)相同,而截距(a)各异的平行线,只要求出其中一条直线,其它直线即可较易求出。
In this paper, the concept of straight line is established by mathematical analysis. The X-ray exposure curves are simply summarized as a set of parallel lines with the same slope (b) and different intercepts (a). As long as one of the straight lines is obtained, Easy to find out.
