The higher the surface energy of the solid substrate in relation to the surface tension of the liquid, the better its wettability, and the smaller the contact Angle.

较高的表面能量的固体基质有关的表面张力的液体，它的更好的润湿性，较小的接触角。

It is shown from the analysis of surface tension that the hot and ion cleaning of photocathode glass substrate can increase the certain degree.

通过表面张力分析，证明对光阴极玻璃基底进行热清洁和离子清洁可以增加玻璃表面的表面能，对提高光阴极的灵敏度有一定的作用。

During the laser sintering, due to the large liquid phase viscosity and surface tension, the balling effect occurred when the molten did not wet the solid metal particle and the underlying substrate.

实验发现，在液相粘度较高、表面张力大，熔体材料不浸润固相颗粒和基板等因素的影响下，烧结过程中出现了球化现象。球化的出现妨碍了直接金属激光烧结成形的顺利进行。

However with the introduction of lighter weight and more flexible plastic substrate magnetic tapes, combined with a vacuum column to control the tension that the magnetic tape experiences during use, the IBM 726 was a prototype of the modern digital tape recording system.
