用毛细管粘度计测量全血粘度是一种简便经济的医学检验方法,但所测得粘度常随所用毛细管的不同,特别是随管半径不同而变化。本文考虑了生物力学中的F(?)hraeus-Lindqvbt效应,提出一种新的数据处理方法,用下式可以较好地拟合全血表观粘度μ_a与管半径a之间的关系: 1/μ_a=D_1+D_2/a, 式中D_1和D_2是常数,与毛细管半径无关。 Measuring the whole blood viscosity with a capillary viscometer is a simple and economical medical test, but the measured viscosity often varies with the capillary used, especially with the tube radius. In this paper, we considered the F (?) Hraeus-Lindqvbt effect in biomechanics and proposed a new data processing method. The relationship between the apparent viscosity μa and the tube radius a / μ_a = D_1 + D_2 / a, where D_1 and D_2 are constants, independent of the capillary radius.
