internal surface

基本解释

Another way to store hydrogen is to put something inside the tank which increases the total internal surface area to which the molecules of the gas can cling.
储存氢的另一方法是在燃料箱中放点东西，增加氢分子能够附着的内表面总面积。
The reaction itself also takes place inside the nanotubes, which are hollow and have a large internal surface area thanks to their thin 20-nanometer-thick walls.
反应本身也在纳米管内部发生。这种中空的纳米管只有20纳米厚的薄壁，所以具有巨大的内表面积。
Root hairs feed from the surface particles, therefore the internal surface area has a great influence on plant food in the soil.
根毛从土粒表面吸收养分，所以，土壤的内表面积对土壤中的植物养分有很大影响。

Supercapacitors have a big internal surface-area that allows a large amount of energy to be delivered rapidly and are used in some electric cars to provide a short burst of power for rapid acceleration and in hybrids to recover energy during braking.
ECONOMIST: Carbon-composite batteries
The micro-USB port, also found along the left edge, is uncovered, but Motorola had the foresight to bathe both the surface and internal circuitry in a water-resistant coating, which should stand up to the wet weather conditions many Europeans will face heading into winter.
