The most important index of radiographic quality is the sensitivity of radiography, which is the size of the smallest defect along the direction of ray penetration that can be found on the negative plate quantitatively. Natural defects’ size are hard to be sure. It is obvious that it is unrealistic to use natural defects to evaluate the sensitivity of radiography. Therefore, in order to facilitate the evaluation of photographic quality, it is often used to monitor the image quali...

According to the daily water quality analysis and laboratory results, supplement the discharge water and control the dosing amount to make it reach the required data index. When the turbidity is >20mgL, increase the amount of drainage water, increase the flow of side filtration, and supplement clean water. According to the current situation of the circulating water system, try to increase the concentration multiple operation to save water and medicine. If the concentration multiplier is g...
