Figures 12, 13 and 14 in Exel file format

Figure 12, Figure 13, and Figure 14 show selected imaginary and real part capacitance spectra (graphs a and b, respectively) recorded over the freezing period for the TVIS vial containing 5% sucrose , 5% sucrose and 0.26% NaCl, and 5% sucrose and 0.55% NaCl. The right side shows the derived parameters of the log of the peak frequency (graph c) and the peak amplitude (graph d) for the principle relaxation peak observed in the imaginary capacitance spectra, i.e.,Maxwell-Wagner process (MW) for the 5% sucrose solution (low conductivity).Interfacial capacitance (IC) for the 5% sucrose solutions with 0.26% and 0.55% solutions (high conductivity).Dielectric relaxation of ice for the frozen state of all three solutions.The right side of Figure 12, Figure 13, and Figure 14 also show the derived parameters of the real capacitance at low and high frequency, given the symbols(10 Hz) and(0.2 MHz), respectively (graphs e and f, respectively). Overlayed on these profiles are the arrows pointing from left to right which have been drawn to indicate/highlight the differences in the temperature dependencies of the real part capacitance in the limits of low and high frequency.<br>The period marked TP is the transition period in which either of the two conditions apply: (i) the peaks of any of the processes are no longer visible within the experimental frequency region of the TVIS instrument, or (ii) the peak observed is a hybrid of multiple processes, for example a peak that comprises contributions from the MW relaxation and from the dielectric relaxation of ice.<br>The other Excel files give a comprehensive set of data, for all three samples, 5% w/v sucrose (with 0% w/vNaCl), 5% w/v sucrose (with 0.26% w/v NaCl), and 5% w/v sucrose (with 0.55% w/v NaCl), to support figures 12, 13, and 14 <br>

图12、图13与图14展示了三组装载于TVIS样品瓶内的溶液在冷冻过程中采集的复电容谱虚部与实部（分别对应子图a、子图b），三组样品分别为含5%蔗糖的溶液、含5%蔗糖与0.26%氯化钠的混合溶液，以及含5%蔗糖与0.55%氯化钠的混合溶液。
各图右侧面板分别展示了从虚部电容谱中提取的主弛豫峰相关参数：对于低电导率的5%蔗糖溶液，该主弛豫为麦克斯韦-瓦格纳（Maxwell-Wagner, MW）弛豫，对应参数为峰频对数（子图c）与峰幅值（子图d）；对于含0.26%和0.55%氯化钠的高电导率5%蔗糖溶液，提取的特征参数为界面电容（Interfacial Capacitance, IC）；而所有三组冷冻样品的弛豫过程则对应冰的介电弛豫。
此外，图12、13、14的右侧面板还展示了高低频区间下的实部电容提取参数，分别以10 Hz与0.2 MHz为代表频段，对应子图e与子图f。这些参数曲线之上叠加了自左向右的箭头，用以标注并凸显高低频极限下实部电容的温度依赖性差异。
标注为TP的区间为转变期，满足以下任一条件即可判定为处于该时期：① 任意弛豫过程的特征峰在TVIS仪器的实验频率范围内不再可观测；② 观测到的峰为多弛豫过程的叠加峰，例如同时包含MW弛豫与冰介电弛豫贡献的复合峰。
其余Excel文件包含了全部三组样品的完整数据集，分别为5%质量体积比（w/v）蔗糖溶液（含0%质量体积比氯化钠）、5%质量体积比蔗糖与0.26%质量体积比氯化钠的混合溶液，以及5%质量体积比蔗糖与0.55%质量体积比氯化钠的混合溶液，用以支撑图12、13、14的绘制。
