不抬，一头高；哈哈，你看看大头在后面

你引用的是3个单独的Cone

 

按equal area cone sensitivity

In this type of display, the peak of each sensitivity curve is scaled up or down so that the area under each curve (equivalent to the total response sensitivity of each type of cone, pooled across all cones) is the same; these curves are usually presented on a linear vertical scale.

equal area cone sensitivity functions

the Stockman & Sharpe (2000) 10° cone fundamentals rescaled so that the area under each curve equals 10 on a linear scale
