1991年 9月— 1 994年 1 2月 ,经 3年半的粘度测知 ,0 5m水深处 ,察尔汗盐湖晶间卤水运动粘滞系数多年平均值为 3 0 68× 1 0 - 2 cm2 /s;3 0m水深处 ,多年平均值为 3 32 4×1 0 - 2 cm2 /s;6 0m水深处 ,多年平均值为 4 0 94× 1 0 - 2 cm2 /s;9 0m水深处 ,多年平均值为5 71 7× 1 0 - 2 cm2 /s;1 2m水深处 ,多年平均值为 5 2 0 7× 1 0 - 2 cm2 /s。从 1 991年 9月— 1 994年 1 2月 ,各卤水深处卤水运动粘滞系数不论是年均值还是月均值均随时间推移而逐渐减小。1 992年 3月— 1 994年 1 2月期间 ,多年来 ,3月份卤水运动粘滞系数为 3 473× 1 0 - 2 cm2 /s,6月份为 3 390× 1 0 - 2 cm2 /s,9月份为 3 496× 1 0 - 2 cm2 /s,1 2月份为 2 576× 1 0 - 2 cm2 /s。由此看出 ,9、3、6月份的值较高 ,1 2月份的较低。晶间卤水运动粘滞系数 (v)等值线基本上是南北走向分布 ,即自东而西减小 ,首采区v值较低 ;表层卤水粘滞系数小 ,深部卤水粘滞系数较大。从 1 991年 9月— 1 992年 1 2月 ,各年份卤水运动粘滞系数的平均值均随卤水深度增加而增加。卤水的粘度系数除与温度及不同种类盐的溶液有关外 ,在察尔汗这种多种盐类组成的卤水中 ,其卤水的运动粘滞系数比重在 1 2 0— 1 30范围内时 ,与比重及镁含量呈好的
From September 1991 to January 1994, after three and a half years’ viscosity measurement, the multi-year average of the coefficient of kinematic viscosity of brine in Chaerhan Salt Lake at 0 5 m depth was 3068 × 10 2 cm 2 / s; 3 0 m depth of water, multi-year average of 3 32 4 × 10 2 cm2 / s; 60 m depth of water, multi-year average of 4 0 94 × 10 2 cm2 / s; 9 0 m water depth, The annual average is 5 71 7 × 10 2 cm2 / s. The average value for many years at the depth of 1 2 m is 52 0 7 × 10 2 cm -2 / s. From September 1991 to January 1994, the coefficient of kinetic viscosity of brine in each brine depth decreased gradually with the passage of time, regardless of whether it was an annual mean value or an average monthly value. During the period from March 1992 to January 1994, the coefficient of motion of marina in March was 3 473 × 10 2 cm2 / s in March and 3 390 × 10 2 cm 2 / s in June, 3 496 × 10 2 cm2 / s in September and 2 576 × 10 2 cm2 / s in February. From this we can see that the values in September, June and June are higher and lower in January and February. The viscous coefficient of vorticity of intergranular brine is basically north-south distribution, decreasing from east to west, and the v value in the first mining area is lower. The viscosity of surface brine is small, and the viscosity of deep brine is larger . From September 1991 to January 2012, the mean value of the kinematic coefficient of brine movement in each year increased with the increase of brine depth. Viscosity coefficient of brine in addition to the temperature and the different types of salt solution, in Chalhan salt of this variety of brine composition, the kinematic viscosity coefficient of brine in the range of 120 ~ 130, And the proportion of magnesium content was good
