The relationship between carbon dioxide and moisture
Drought is one of the most commonly studied environmental stress factors. The increase of carbon dioxide concentration, the reduction of plant transpiration loss, the enhancement of water conservation capacity of plants, and the more pronounced performance in arid environment. Certain plants grown under conditions of high concentrations of carbon dioxide under drought stress maintain a longer period of physiological function than those grown under normal concentrations. Experts believe that the increase in carbon dioxide concentration will reduce the stomatal conductance of the leaves, thus reducing the loss of water from transpiration. However, the experimental study observed the opposite result and found that the stomatal conductance of plant needles growing under normal atmospheric carbon dioxide concentration showed a slight negative correlation with carbon dioxide concentration, and showed a slight positive correlation under water stress conditions. . In a water-restricted environment, increased concentrations of carbon dioxide may allow plants to alleviate drought stress. Plants grown at high carbon dioxide concentrations are able to compensate for water stress better than similar plants at low carbon dioxide concentrations. Optical Vacuum Coating Machine
Optical coating machine is one of the vacuuming coating technology. By depositing the organic fluoride on the substrate, it can achieve the following function: waterproof, oil proof, anti fingerprint, anti-pollution. the common application is AF glass or AF metal on touch panel. Apart from the AF application, it can also apply to anti-rust, anti-pollution and protective film.with arc shape fixture or arch fixture, can be used for multi-layer film such as: the short wave pass, long wave pass, AR, light filter and widely used for optical lens, electronic products, acrylic, glass, lamp, touch screen, lunette, telescope, microscope, stage light, light lamp and phone case, the optional color of the product: AR, light filter, unreal color, red multicolored , red, yellow, green, blue and rainbow.
