When discussing the rheological properties of normal and leukemic blood it must be considered that blood is a suspension of cells in aqueous solution which is also known as plasma. Whole blood viscosity and plasma viscosity were determined by Rheometer LS30 which allows measuring whole blood and plasma viscosity in the middle and low shear rate ranges. The measurements of the viscosity showed that whole blood and plasma behave as non-Newtonian power law fluid. The values of n (non-Newtonian index) and k (consistency index) of power law fluid were calculated for both leukemic blood and plasma samples. The importance of this phenomenon for the micro-circulation is discussed.
在讨论正常血液和白血病血液的流变学特性时，必须考虑到血液是细胞在水溶液（即血浆）中的悬浮液。全血粘度和血浆粘度由流变仪LS30测定，该仪器可在中低剪切速率范围内测量全血和血浆粘度。粘度测量结果表明，全血和血浆表现为非牛顿幂律流体。计算了白血病血液和血浆样本幂律流体的n（非牛顿指数）和k（稠度指数）值。讨论了这种现象对微循环的重要性。
