Experimental Equipment for Studying Correlation Between Photosynthesis and SO₂ Absorption Ability of Plants

In order to find out the photosynthesis and SO₂ absorption ability of plants simultanously, a measuring system consisting of infrared ray CO₂ analyzer and SO₂ gas analyzer was used to measure the relevant parameters . After investigated and tested the jam resistance ability, pipe line set up of gas path, and the humidity controling, It is shown that this system is proven to be satisfactory for the design goal basically.
