Note. The moisture content at a certain moment is the instantaneous moisture content, and the arithmetic mean of the instantaneous moisture content in a certain period is the average moisture content. 3.2 Probe erasing function functionofprobecleaning Remove the attachment from the probe surface to eliminate its effect on measurement accuracy. 3.3 Oil phase point oilphasepoint The crude oil is located at a certain point in the oil phase. 3.4 Water phase point waterphasepoint The crude oil is located at a certain point in the water phase.4 Summary of basic principles and methods4.1 Basic principles According to the Beer's law and the physical properties of electromagnetic waves, when electromagnetic waves of the same frequency pass through different concentrations of media, due to the absorption of the medium ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 25104-2019_English be delivered?Answer: Upon your order, we will start to translate GB/T 25104-2019_English as soon as possible, and keep you informed of the progress.
