冷冻-抽真空-溶解三步循环，在真空管线下操作，用来为溶液除气
然而,three pump-freeze–thaw cycle 技术通过快速实现低温冷冻和恢复室温的解冻过程,可以最大限度地保留食物的原始质量和口感。这使得这种技术特别适用于各种肉类、海鲜、水果和蔬菜等易腐食品的处理与储存。 此外,在食品加工过程中,three pump-freeze–thaw cycle 技术还常常与其他传统处理手段如真空包装或真空封带...
将封管里的溶液用液氮冻成固体,抽真空,充氮气,解冻,这个过程重复两三次,彻底除去体系中的残留氧气 天山明月 欲脱气的溶液放在Schlenk管中,用液氮冷冻成固体,抽真空。温热使液体融化,在此过程中液体中少量残留气体就会排出。重新冷冻,抽真空。再温热使融...重复三次,保证体系脱气完全。 fandream 通常用于无氧反应除...

Soil freeze-thaw (FT) cycles over agricultural lands are of great importance due to their vital role in controlling soil moisture distribution, nutrient availability, health of microbial communities, and water partitioning during flood events. Active microwave sensors such as C-band Sent...
The mixture was ultra- sonicated for 15 min at 25 °C and degassed using three freeze-pump-thaw cycles. The tube was then sealed and kept in an autoclave at 120 °C for 3 days. The precipitate was filtered off, exhaustively washed by Soxhlet extractions with water, methanol and ...
(0.004 g, 0.02 mmol) were mixed in a 25 mL Schlenk flask, and the solution was degassed by three freeze-pump-thaw cycles. The mixture was then heated under nitrogen at 90 °C for 20 h. The polymerization was stopped by cooling the reaction flask in liquid nitrogen. The ...
The study reported here was conducted to determine freeze-thaw influences on the vertical hydraulic conductivity of soil. To accomplish this three soil aggregate sizes (0.0 to 0.8 mm, 0.8 to 1.2 mm, and 1.2 to 2.0 mm) were packed in aluminum cores, equilibrated at two water levels (maximum...
