High-field H NMR T relaxation studies were used to characterize the changes in the physical phases of water, NaCl, and dextrose solutions over a temperature range of -65 to 15 °C. The data were analyzed with the inverse Laplace transform and with a linear fit to the logarithm of the time domain signal. Two liquid phases were detected for the NaCl and dextrose solutions at lower temperatures and assigned to low and high concentrated solution domains. The high concentrated solution domain was found to be present between -30 and -5 °C in the NaCl solution and between -55 and -5 °C in the dextrose solution. Copyright © 2017 John Wiley & Sons, Ltd.
采用高场¹H核磁共振弛豫研究来表征水、氯化钠和葡萄糖溶液在-65至15°C温度范围内物理相的变化。利用逆拉普拉斯变换和对时域信号对数的线性拟合对数据进行分析。在较低温度下,检测到氯化钠和葡萄糖溶液存在两种液相,并将其分别归为低浓度和高浓度溶液区域。发现高浓度溶液区域在氯化钠溶液中存在于-30至-5°C之间,在葡萄糖溶液中存在于-55至-5°C之间。版权所有© 2017约翰·威利父子有限公司。
