diffusion constant

例句：

1. 1. The diffusion constant of the gas in the container is very low.
   容器中气体的扩散常数非常低。
2. 2.The diffusion constant of the gas in the container is very low, which means that it takes a long time for the gas to diffuse throughout the container.
   容器中气体的扩散常数非常低，这意味着气体需要很长时间才能在整个容器中扩散。
3. 3. The diffusion constant of the gas in the container is very low, which means that it takes a long time for thegas to diffuse throughout the container. This is due to the fact that the gas molecules have a tendency to move towards regions of high concentration.
   容器中气体的扩散常数非常低，这意味着气体需要很长时间才能在整个容器中扩散。这是因为气体分子有向浓度高的区域移动的倾向。
