Low-temperature freeze-thaw embolism branch hydraulic conductivity measurement sample pretreatment method

The invention discloses a low-temperature freeze-thaw embolism branch hydraulic conductivity measurement sample pretreatment method, which is characterized in that a collected to-be-measured branch is subjected to sealing treatment, and the sealing treatment is one of water sealing, hot melt adhesive sealing, wax sealing or wound healing agent sealing. According to the method, various sealing methods such as water sealing, wax sealing and wound healing agent sealing are adopted at the cut of the branch, the side face of the branch is wrapped with the plastic film, water loss of the branch is reduced from multiple angles, and the water conductivity measuring accuracy is improved. 本发明公开了一种低温冻融栓塞枝条导水度测量样品前处理方法，将采集的待测枝条进行封闭处理，所述的封闭处理为水封、热熔胶封、蜡封或伤口愈合剂封闭中的一种。本发明对枝条在切口处分别使用水封、蜡封、伤口愈合剂封等多种封口办法，且采用塑料薄膜将枝条侧面包裹，多角度减少枝条的水分散失，有利于导水度测量准确性的提升。
