Measure of the Photosynthetic Efficiency of the Cabbage Leaves by Using Photo-Acoustic Tomography Spectroscopy Technology

By using a new type of photo-acoustic tomography spectroscopy with non-damage and weak signals detection, the normalized photo-acoustic tomography spectroscopy (PAS-CT) and optical absorption characteristic of the green and yellow leaves of the cabbage are measured. The results show that: the leaves of the cabbage could get different levels of photo-acoustic spectroscopy from different chopping frequency. The chloroplast number in the yellow leaves was less than that in the green leaves, so the photosynthesis in the yellow leaves was significantly weakened compared with the green leaves. The more the chloroplast number in the cabbage leaves were, the stronger the photosynthesis was and the higher the photosynthetic efficiency was. The chopping frequency of 24Hz could activate more chloroplasts than 34Hz and improve the photosynthetic efficiency of the cabbage leaves. What’s more, it could improve the yield of cabbage. Photo-acoustic tomography spectroscopy is a new way of studying photosynthesis. It has a bright and far-reaching future.

Different Levels

The electromechanical properties of elastomer material change when different levels of stretching are applied to the elastomer film. The generated stress and expansion of the EAP material depend on the electric field across the material and its relative permeability. Some of the best known commercial dielectric elastomer materials are based on acrylic elastomers, e.g. 3M VHB 4910 or 4905 adhesive tape. In this work, the VHB 4910 tape was used as a reference material for different types of acrylic nanoclay compound materials. These new type of nanoclay elastomer compounds were tested because the addition of clay into the elastomer was assumed to increase its actuating performance. Different voltage and pre-stretching levels were used in the measurements. Current-voltage characteristics and isometric stress measurements were used to study the energy efficiency, frequency dependent behavior, reactivity and isometric stress performance of the EAP materials. Based on the electromechanical characterization and material properties, a general hyperelastic material model was developed. According to the preliminary tests, the nanoclay compound seems to be a bit stiffer than VHB 4910 resulting in a greater isometric stress response.
