   對dui於yu含han蠟la較jiao多duo的de油you品pin，隨sui著zhe溫wen度du的de降jiang低di，油you品pin中zhong高gao熔rong點dian烴ting類lei的de溶rong解jie度du降jiang低di
，當dang達da到dao飽bao和he狀zhuang態tai時shi，就jiu會hui以yi結jie晶jing析xi出chu。最zui初chu析xi出chu的de是shi肉rou眼yan觀guan察cha不bu到dao細xi微wei的de顆ke粒li結jie晶jing，使shi原yuan來lai透tou明ming的de油you品pin變bian渾hun濁zhuo。繼ji續xu冷leng卻que，蠟la的de結jie晶jing就jiu會hui逐zhu漸jian長chang大da
，進jin一yi步bu降jiang溫wen
，蠟la的de結jie晶jing大da量liang生sheng成cheng，形xing成cheng的de網wang狀zhuang的de結jie晶jing骨gu架jia，就jiu會hui將jiang液ye態tai的de油you包bao在zai其qi中zhong，使shi整zheng個ge油you品pin失shi去qu流liu動dong性xing
，這zhe種zhong現xian象xiang稱cheng為wei結jie構gou凝ning固gu（或構造凝固）。影響結構凝固的是油品中高熔點的正構烷烴、異構烷烴及帶長烷基側鏈的環狀烴。
