凹形

Under a lower pressure, the relationship between C/H and CO adsorption quantity was a beeline and the CO adsorption quantity increases with the of C/H ratio. The relationship between C/H and CO adsorption is a concave curve with the pressure increasing, and the higher the pressure, the higher the discrete degree.
