I. V. Yamaikina,a Z. P. Shul'man,sup>a L. I. Ershova,b Z. M. Likhovetskaya,b and N. A. Gorbunovab UDC 532.529+527 A new model of approximation of the blood-flow curve with five parameters independent of the hematocrit and the rate of shear is proposed. On the basis of the statistical analysis, we have shown the reliability of differences of the mean values of the independently measured aggregatability and deformability of erythrocytes and the parameters of the new rheological model of hematological patients (myeloma, erythremia, anemia, blood loss) from donors. The relation of two parameters of the model, 1 and 3 , to the aggregatibility and deformability of erythrocytes, respectively, has been proved. aA. V.
