When two spheres with an interstitial Herschel-Bulkley fluid translate normally, the velocity and the squeeze force distributions are investigated. It is shown that the solution of the squeeze force can reduced to the Bingham and power-law fluid cases, respectively. 研究了存在填隙Herschel-Bulkley流体时两球法向运动时的挤压力,并且证明了法向挤压力的解分别可以退回到宾汉流体或幂律流体情形。
