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.

Tungsten carbide welding rope is a type of welding filler material that is used for hardfacing applications. It is made by combining tungsten carbide particles with a binding material, such as nickel or cobalt, to create a rope-like form.
Tungsten carbide is known for its exceptional hardness and wear resistance, making it ideal for applications where the welded surface needs to withstand extreme abrasion and impact. The welding rope is typically used in industries such as mining, oil and gas, construction, and agriculture.
When the tungsten carbide welding rope is heated during the welding process, the binding material melts and fuses the tungsten carbide particles to the base metal, creating a hard and durable surface. This helps to extend the lifespan of equipment and machinery by protecting it from wear and tear.
Tungsten carbide welding rope can be applied using various welding processes, including manual metal arc welding (MMA), gas tungsten arc welding (GTAW), and flux-cored arc welding (FCAW). The choice of welding process depends on the specific application and the equipment available.
Overall, tungsten carbide welding rope offers a cost-effective solution for protecting and repairing high-wear surfaces, making it a popular choice in industries where durability and longevity are essential.
