摘要
蒸馏水、盐水、血浆、血清等均被用作生物摩擦磨损研究中的润滑剂.由于血浆在成分上与人体组织液相近,作为生物摩擦磨损的润滑剂,更接近于真实情况,但对其粘度特性并未认真考察.本文采用生理盐水稀释,对不同浓度的抗凝新鲜血浆的粘度特性进行了研究.并对其影响因素进行了讨论.结果表明:在我们的实验条件下,血浆表现出非牛顿性,影响因素中以切变率的影响作用较大.
As Lubricant, distilled water, saline, plasma and serum have been used in the field of biofriction and wear.The component of plasma is similar to that of body tissue fluid, as a lubricant, it is mostly close to the real condition. But its lubricating characteristics have not been completely studied. In this paper, the viscosity of fresh and anticoagulant plasma with different concentration were studied by using physiological saline as diluent. Effective factors were discussed. Under our experimental conditions, it was found that plasma displayed its properties of Non - Newton and the most important effective factor was shear rate.
