With elongated treated time and increasedthickness of coating, loose coating begins to appear on the coating exterior, at last the thickness can reach 90% of total thickness.
随着处理时间的延长及膜层的增厚，其外侧开始出现疏松层，最终可达到膜层总厚度的90 %左右。

As airfoil thickness is increased, the average pressure drag, affected by leading edge vortex is reduced even to be negative, and meanwhile friction has little increase.
由于前缘涡的影响，翼型厚度增加，平均压差阻力系数变小，甚至会出现负值。

The corneal thicknessincreased and the injury of endothelium aggravated when intraocular tension increased.
