freezing and thawing cycle

基本解释

It results the thickness of ice layer continuously increasing in freezing and thawing cycles.
它导致反复冻融循环时冰层厚度不断增加。
The sweet sap is collected from maple trees in the spring when freezing and thawing cycles cause it to rise and flow from taps hammered into tree trunks.
这种甜的枫树液在春季采集，反复的冻融导致它上升沿着打进树干的导管流出来。
So it is important to the reinforced concrete structures exposed in salt environment and subjected to freezing and thawing cycles for the durability design.
所以，对于盐环境中经受冻融循环作用的钢筋混凝土结构，加强其耐久性设计非常重要。
