“有效厚度”常见的英文表达是 “effective thickness” 。
例如在石油地质、材料科学等不同领域中,都可能会用到这个表述:
In petroleum geology, the effective thickness of the reservoir layer is a crucial parameter for evaluating oil reserves.(在石油地质学中,储层的有效厚度是评估石油储量的一个关键参数。)
The effective thickness of this coating determines its insulation performance.(这种涂层的有效厚度决定了其隔热性能。)
