求解Hydraulic Library中的一张图

最近阅读Hydraulic Library（2008版）发现下面一张，不理解其中含义，请赐教
Figure 2.46 shows the bulk modulus of a diesel fuel at 40 °C with 0, 0.01, 0.1, 1, 10% air. The plot is obtained using the system
shown. The model of the diesel fuel properties is based on accurate experimental measurements and are designed for use with injection system which are very fast acting. For this reason air is assumed to be entrained rather than dissolved.

上图表示含不同空气量的柴油的弹性体积模量随着柴油所受压力的变化。

谢谢
