A: CO2 is a carbon source for photosynthesis. Experimental studies have shown that if the CO2 concentration is increased from atmospheric concentration (about 300 PPM) to 1000 PPM, the photosynthetic efficiency of plants can be more than doubled; if the CO2 concentration is lowered to 50 PPM, photosynthesis is stopped due to lack of raw materials. The CO2 concentration is in the range of 100-2000 PPM, and the crop yield increases as the CO2 concentration increases. When formulating with silica...

The rectification principle and waveform set the potential of the transformer secondary coil as the effective value of the phase potential. During the positive half of e, the potential at point a at the upper end of the secondary winding of the transformer is higher than the potential at point b at the lower end of the transformer. The end of a flows through the load R through Z and returns to the end of b, as shown by the solid arrows in FIG. 2. During the negative half of e, the potential at...
