血清蛋白电泳计算复杂,而且易发生笔误。采用图解方法,较通常的方法运算快,亦便于核对结果。[原理]一系列平行线,被一束呈放射的线条分割成若干段,同时形成许多相似三角形。运用更比定理,可证明每条平行线其相应各段的比例相等(图1)。[算具]1、图纸和引线(图2): Serum protein electrophoresis is complicated, and prone to clerical errors. The use of graphical methods, faster than the usual method of operation, but also easy to check the results. [Principle] A series of parallel lines are divided into several segments by a beam of radiation, forming many similar triangles. Using more than theorem, each parallel line can prove that the proportion of its corresponding segments equal (Figure 1). [Computing] 1, drawings and leads (Figure 2):
