【摘要】 通过对槐树(国槐)和刺槐2种植物枝茎内的液体进行黏度测试,结果表明:这2种植物体内的液体是典型的非牛顿流体;同时研究了液体黏度与剪切应力的关系,试验结果显示,在低剪切应力区,随剪切应力的增大,液体的黏度变小,当剪切应力增大到一定值时,剪切应力的变化对黏度的影响趋缓,并拟合出黏度与剪切应力的本构方程。更多还原

【Abstract】 The relationship of viscosity and shearing stress of liquid in branch of Sophora japonica L.and Robinica pseudoacacia L.was studied in this paper.The liquid is non-Newtonian fluid.It is found that viscosity reduced according to shearing stress increased in section of lower shearing stress,and changed little in the section of hight shearing stress.A related test fiting curve was obtained from the test,and counstitutive equation was obtained.更多还原
