Under the different freezing - thawing cycle circumstance, three factors of water binder ratio, air content and mineral admixture are analyzed by using the method of orthogonal table. the test results show that the chief influencing factor is the water binder ratio in water freezing - thawing cycle circumstance, and in salt freezing - thawing cycle circumstance is the air content. this could illustrate that entraining air into concrete can improve the frost resistance of concrete effectively in salt freezing - thawing cycle
分析了在純水和3 . 5 % nacl溶液中受凍后，水膠比、含氣量和摻合料對混凝土飽和系數及變化速率的影響規律，試驗結果表明水膠比對混凝土水凍時的飽和系數及變化速率影響顯著，而鹽凍情況下含氣量則是主要影響因素，說明引氣能顯著提高混凝土的抗鹽凍性能。 -
In the low - temperature - freezing stage, the water is frozen as ice phase, while the solute precipitate as the salt phase. the velocity of ice phase growth ( vf ) in the solution and the velocity of solute diffusion ( vd ) decide that whether the heavy segregation of solute appears
當低溫冷凍時，水以冰的形式凍結，溶質則以鹽的形式析出，形成冰鹽兩相;冰相生長速率和溶質擴散速率決定了溶質鹽是否發生大的偏聚。 -
As is known that the water in the rock contains a mount of salt, and the kind and content in turn make the water freezing temperature variable. on the ot her hand, rock material will shrink when frozen, and expand when warmed
主要是由於巖石中的水融有一定量的鹽類物質，鹽類物質的存在及其含量的差異使的水分的冰點具有一定的可變性，而巖石材料本身具有熱脹冷縮的性質。 -
Extracting can also be done by partially freezing the salt solution
加熱蒸餾法是將鹽水加熱，使水分蒸發，然後再使蒸汽冷凝成水。 -
It was shown that salt expansion value of low liquid - limit clay was accumulated before the sixth freezing and thawing cycles, but the increment of salt expansion was reduced gradually with increasing cycles ; the salt expansion accumulation of low liquid - limit clay could be separated into three phases ; the deformation of clayey sand was mostly frost heave and subsidence under cycles, and collapsibility value of clayey sand was accumulated with increasing cycles ; the variation of salt expansion ratio and collapsibility ratio was a parabolic function of freezing and thawing cycles
試驗結果表明：低液限粘土前五次凍融循環過程中鹽脹具有較好累加性，隨著凍融循環次數的增加，鹽脹量增長速度逐漸降低；含砂低液限粘土的鹽脹過程可以被分為三個階段；粘土質砂在凍融循環過程中的變形主要為凍脹和沉降變形，具有較好的溶陷累加性；低液限粘土、含砂低液限粘土的鹽脹率和粘土質砂的溶陷率與凍融周期之間的關系符合二次拋物線變化規律。 -
This paper analyzes on some factors influencing the water accumulation during the soil freezing process, probes into the mechanism of the water and salt migration during the process of water accumulation, and points out that the water accumulation of frozen zone provides the effect of water and salt migration for the hibernating propagation of the forest in the seasons of winter and spring
分析了土壤凍結過程中水分積聚的影響因素，探討了水分積聚過程中水鹽遷移的機理，指出凍結帶水分積聚為冬春季林木越冬繁衍提供了水分，同時鹽分也隨水分遷移到地表。 -
I. roles of dehydrins in plant tolerance to freezing and drought. accumulations of heat - stable proteins and dehydrins induced by dehydration, low temperature, osmotic stress, high salt or aba treatment were investigated in protocorm - like - bodies ( plbs ) ofdendrobium candidum. moreover, we described the relationship between these accumulations and the development of tolerance to stresses
