针对海冰密度排液法测试中需要一种冰点低且粘度合适的液体,发现蜂蜜-盐水溶液以其不冻结、粘度高、易储存等特点成为最具潜力的理想“标靶”液体.通过配制不同蜂蜜与盐水体积百分比浓度的溶液,测试这些蜂蜜-盐水溶液在不同温度下的粘度.利用正交试验测试数据,结合文献报道的理论及数学表达式,统计分析了溶液粘度分别同温度、浓度的特征;最后建立了描述蜂蜜-盐水溶液粘度同温度和浓度之间的综合统计关系.能够用来计算在特定温度范围内,所要求理想粘度对应的蜂蜜-盐水溶液的体积百分比.由此配制的蜂蜜-盐水溶液可以成为排液法准确测量不规则海冰样品密度的核心技术支撑.
For the sea ice density drainage test requires a low freezing point and the viscosity of the liquid and found that honey - salt solution with its non-freezing, high viscosity, easy to store characteristics such as the most potential to become the ideal “target” liquid The viscosities of these honey-brine solutions at different temperatures were tested by preparing solutions of different concentrations of honey and brine.Using the orthogonal test data and the theoretical and mathematical expressions reported in the literature, Temperature, and concentration characteristics; and finally, a comprehensive statistical relationship describing the viscosity of honey-brine solution with temperature and concentration can be used to calculate the volume percentage of the honey-brine solution corresponding to the desired ideal viscosity over a specific temperature range. The honey-salt solution thus prepared can be the core technical support of the discharge method for accurately measuring the density of irregular sea ice samples.
