采用LVDV-III+型流变仪对不同离心速度、离心时间下的海棠汁流变特性进行研究，研究发现海棠汁随着剪切速率增大，表观粘度逐渐增大，剪切应力随之增大；同时随着剪切速率的逐渐增大，表观粘度大小的变化趋势较小但表现出较微的上升趋势。通过Herschel-Bulkley方程拟合，R2都在0.99以上,并就方程中参数的变化进行了解释说明，流动指数n值大于1，海棠汁流变特性符合胀塑性流体的基本特征。

This paper uses LVDV-III+type rheometer at different centrifugation speed, centrifugation time under the crabapple juice to study the rheological characteristics. It was found that with the shear rate increases, apparent viscosity and shear stress of crabapple juice gradually increased. As the shear rate increases, the size of the trends apparent viscosity showed relatively small but the slight upward trend. Crabapple juice was in line with inflation plastic fluid rheological properties of the basic characteristics. Though Herschel-Bulkley equation by fitting, R2 was above 0.99 and on the parameters of the equation describes the change was explained.
