potential energy barrier

基本解释

This is because that the deposition of the particles will increase the potential energy barrier for de-pining.
分析表明这和颗粒沉积引起的解附势垒增高有关。
It has shown that less 1, 2-unit content corresponds to lower potential barrier of internal rotation and hence to lower energy of rotational isomerization.
进一步的研究表明，低1，2-链节含量对应着较低的分子链内旋转势垒和内旋转异构化能。
A step on Ni(100) will increase the potential barrier and activation energy for the diffusing H atom across this step, and causing the anisotropy of SD of H on the stepped Ni surface.
面上的台阶，将使通过此台阶的H原子的扩散势垒增高，激活能增大，且引起扩散的各向异性。
