Abstract

The invention discloses a method for measuring the transmission rate of a liquid adherent boundary layer under the effect of an external electric field. The method comprises the steps that an adherent boundary layer area of liquid is determined according to intensity of the electric field and the liquid thickness in the direction of incident rays, and the incident position of the incident rays on a sample groove is determined according to the adherent boundary layer area; incident light intensity of the incident rays and first transmission light intensity after the incident rays penetrate through the empty sample groove are obtained, and light absorbing intensity of the empty sample groove is determined according to the incident light intensity and the first transmission light intensity; incident light intensity of the incident rays and second transmission light intensity after the incident rays penetrate through the sample groove containing liquid to be measured are obtained; based on the incident light intensity, the light absorbing intensity of the empty sample groove and the second transmission light intensity, the transmission rate of the liquid to be measured is determined. The method can achieve the effect of measuring the transmission rate in the electrorheological fluid / ionic liquid boundary layer under the effect of the external electric field.

Description

technical field [0001] The invention relates to the field of measuring microscale physical property parameters, in particular to a method for measuring the transmittance of a liquid-adhered boundary layer under the action of an external electric field. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] At present, the equipment for testing the transmittance of microscale samples is mainly a microscope. Among them, due to its invisibility, the infrared band is far more complicated to measure than the visible band. Infrared microscopes are currently commonly used in the fields of electronic equipment detection and failure prevention, infrared thermal imaging, and reliability analysis of microelectronic chip circuits. Layers of polymers with different components, testing semiconductor devices, integrated circuits, ...
