切变率是指流动的两层液体之间每单位距离内的流动速度，与液体粘度成反比，即低切变率时粘度升高，高切变率时粘度降低。
基于血流变理论，设计了一套用于测量不同切变率下表观粘度的密闭管道系统。
Based on hemorheology theory, a suit of airtight pipeline system is designed, which is used to measure apparent viscosity with different shear rates.
设计的锥板粘度计由产生不同切变率的机械传动装置、放置血样的试样杯和锥板等装置组成。
The viscometer was composed of mechanical rotating parts creating different shear rate, a sample cup and a cone plank.
结论雌激素替代治疗结合一定频率和幅度的振动运动，可使低切变率下的全血粘度值明显降低。
Conclusion it was shown that blood viscosity at low shear rates can be decreased by certain intensity vibrating movement in ovariectomized rats with appropriate estradiol valerate replacement therapy.
