barrier penetration

基本解释

AIM: To predict the blood-brain barrier penetration by polar molecular surface area and molecular volume.
目的：用极性表面积和分子体积预测药物对血脑屏障的穿透性。
The Barrier Penetration Model has been used to calculate the heavy ion fusion cross section and it does give a good description of the experimental data in existence.
本文利用势垒穿透模型计算重离子融合反应截面，我们发现理论计算结果同现有的实验数据符合得相当好。
Intermolecular electron transfer, which is known to play usually a dominant role in photoelectric conversion processes, is regarded as an electronic intermolecular barrier penetration process.
光电转换过程中起主导作用的分子间电子转移可视为电子在分子间势垒穿透的过程。

But the biggest barrier to penetration in this market is parents.
