Diffusion is the passive movement of substances from a region of higher concentrationto a region of lower concentration. Diffusion of substances plays an important role incellular transport in plants. Rate of diffusion is affected by concentration gradient,membrane permeability, temperature, and pressure...
The rate of diffusion varies with the type of technology and is determined by the degree of difficulty of transfer. The costs of transferring the technology increase with the difficulty. 相关知识点: 试题来源: 解析 技术由于类型的不同,扩散速度也不同,它由转让的难度所决定。技术转让的难度越大成...
What is diffusion, and how would you expect it to be affected by temperature and molecular weight? What is the major factor that affects diffusion? How does molecular weight (size of a molecule) influence its rate of diffusion? What are some factors that can alter the speed of diffusion?
Molecules are constantly moving around due to the amount of thermal energy they have. This movement is affected by the size of the particle and the environment the particle is in. Particles will always move around in a medium but the overall rate of diffusion can be affected by many factors....
aDo ‘late’ adopters catch up with ‘early’ adopters? `’养父母是否及早后捉住与`’养父母?[translate] aa rate of diffusion that is faster than early adopters, although the lead by early 比养父母及早快速扩散的率,虽然及早主角[translate]...
Diffusion:Diffusion involves the movement of particles or molecular from the region where they are highly concentrated to an area where they are less concentrated. It plays a vital role in both plants and animals as it aids the transport of essential materials into the cells of both plants a...
Besides, when during cooling down a phase transition takes place, the rate determines the degree of diffusion during this transition. For example, for titanium a martensitic phase transformation takes place only from the β to the α phase for high cooling rates. Second, the cooling rates ...
aIt is likely that the diffusion rate of generics varies across different segments of consumers. Intuitively, I expect that the diffusion rate of generics is faster in the price-sensitive segment of the market. However, with only aggregate level data, I do not observe the demand patterns of th...
Diffusion is a process in which substances move across membranes, from an area of higher concentration (of the substance) to an area of lower concentration (of the substance), until the concentration of the substance becomes equal on both sides. It is a typ...
