- 摘要：
FIELD: physics. ^ SUBSTANCE: liquid reservoir has a transparent wall and a microrelief layer, having a microrelief structure and lying on the outer surface of the wall, and a protective layer covering the microrelief structure, arranged in order from the wall. The protective layer has refraction index which is essentially equal to that of the liquid to be stored in the reservoir. ^ EFFECT: reduced reflection from the surface of the reservoir and longevity. ^ 22 cl, 19 dwg
