As the duration of the filter cake layer thickness, increase, resistance increases, filtering the duration of the pressure difference with a straight-line growth.
随着过滤时间的持续，饼层厚度增加，阻力增大，过滤压差随时间的持续呈直线增长。

The relation between the air gap thickness and the peak wavelength in micro-optical electromechanical system (MOEMS) optical tunable filter based on Fabry-Perot etalon is discussed.
分析了基于法布里珀罗腔的微光机电系统可调谐滤波器中，空气腔厚度与峰值波长间的关系。

Trust is also an affective factor which works directly on the thickness of the filter, so it should be regarded as the forth important factor in addition to motivation, confidence and anxiety.
