扩散的英文怎么说?
<1>扩散的英文怎么说?1> Spread or diffusion is the process of a substance or particle’s movement from one point to another. There are several theories which attempt to explain this phenomenon, but what is clear is that it is a vital part of many ecological, physical, chemical and biological processes. The most common form of spread is through diffusion, which is the movement of a substance or particle from an area of higher concentration to lower concentrations. This is the process by which a temperature gradient is established by the molecules of a substance which decreases from one section to another. Although this process is similar to convection and advection, both of which involve molecular motion, diffusion is distinct in that it involves movement through molecular interaction. This is the most common spread process and is an essential part of many systems in nature. 您可能还想了解: 龘笔顺_龘笔画多少 靐笔顺_靐笔画多少 (zest造句大全)zest什么意思|zest用法和短句 Diffusion can also occur in both solid and liquid forms. This is known as surface diffusion, which is the movement of molecules from one location on a surface to another. It occurs when a solid has a high concentration of one particular substance and the molecules are able to move from one end to the other along a surface. This is an important part of many processes in nature such as soil drainage, the movement of nutrients and metals, and the spread of infection in organisms. The process of spread can also be through advection and convection which are framed by conservation of energy. This means that heat will travel from one area to another because of the differences in temperature and pressure. This can become incredibly important in the weather cycle and causes water to move from the ocean to the land and then back out. Finally, spread can also occur by the process of deposition or entrainment. This occurs when a particle's movement is caused by another force such as winds or even water currents. These particles are moved to different areas and can be extremely important in weather systems as it helps to move things like rainfall from one area to another. To conclude, spread plays an essential role in many processes which occur in nature and can be dated back to the times of Aristotle and Newton. There are several processes which can explain the movement of particles and substances from one location to another and they are continually researched and studied to gain a better understanding of the world. |
