Figure of Zoom in1000 times b. 3D Figure of Zoom in 3000 times Figure 3: 3D microscope photograph of untreated corn stalk at different magnifications Untreated surface of corn stalks is relatively smooth and flat, there’s not many empty holes on it, and the wax layer is not damaged. By analysis of Figure 1c we can see that, with the increase of microwave reaction time, the yield of reducing sugar gradually increases, and the yield of reducing sugar reaches maximum when the reaction time is 20min.	cache/cet-1018.pdf	txt/cet-1018.txt
