The viscosity of liquids can be measured in the diamond-anvil pressure cell utilizing a falling-solid sphere method and the ruby technique for pressure measurement. The pressure dependence of the viscosity of a 4:1 mixture (by volume) of methanol-ethanol was determined to 70 kilobars. The accuracy of the method is estimated from measurements made on a fluid of known viscosity.
液体的粘度可以在金刚石对顶砧压力室中采用落球法并结合用于压力测量的红宝石技术来测量。测定了甲醇 - 乙醇体积比为4:1的混合物在70千巴压力下粘度与压力的关系。该方法的准确性是通过对已知粘度的流体进行测量来估计的。
