Herschel-Bulkley rheological model is one of those with three parameters. It can properly represent heological properties of mud, cement lurry and polymer solutions over a wide range and with considerable saccuracy. Based on foundational equations of rheological model, and by using extended form of power progression, this paper has derived the rheological law of fluid in horizontal rotation, and its accurate calculating expression. The error resulted from the conventional representations of theology, and the related factors have been analyzed. The extended representations of power progression is only an approximate expression, but it is adequate for engineering use. In addition, a shear-stress formula has been derived for the purpose of more accuracy.

Herschel——Bulkley流变模式是一个三参数的流变横式,它能较好地反映泥浆、水泥浆及高分子溶液等的流变性能,并具有适应范围广、精度较高的特点。 本文从该流变模式的本构方程出发,应用幂级数的展开形式,推导出液体作水平旋转运动的流变规律及其精确的流变参数计算式,同时分析了用一般表达式计算流变参数所造成的误差和影响因素。幂级数的展开式虽是一个近似的式子,但其精确性巳能满足工程上的要求。 为了提高流变参数的精确性,文中还推证出某一剪切应力的计算公式。

A set of axisymmetric dynamic equations is used for investigating the effects of horizontal rotating current on convective movement. It is concluded that the configuration of updraft may be changed in the presence of horizontal rotatiog current. By comparison with convection, in the absence of horizontal rotating current, the vertical distribution of changed updraft has an appreciable eharacteristic i.e., the strength of updraft increases in the middle-lower part of convection and decreases in the middle-upper...

A set of axisymmetric dynamic equations is used for investigating the effects of horizontal rotating current on convective movement. It is concluded that the configuration of updraft may be changed in the presence of horizontal rotatiog current. By comparison with convection, in the absence of horizontal rotating current, the vertical distribution of changed updraft has an appreciable eharacteristic i.e., the strength of updraft increases in the middle-lower part of convection and decreases in the middle-upper part of convection, thus the maximum vertical velocity becomes greater and it's height moves down. Furthermore, the thickness of strong convective region reduces. These results should help to interpret such observation facts as supercell's longer life duration, larger strength, and thinner cloud layer than other hailstorm.The adjustment of disturbance pressure field is analysed. It is speculated that the effect of horizontal rotating current on updraft will be realized through the adjustment of pressure field.

用轴对称动力方程组研究对流运动中水平旋转气流的作用,结果表明,有水平旋转气流存在时,将使对流运动中下部的上升气流明显加强,上部减弱,使调整后的垂直气流结构强度增加,强中心高度变低,对流厚度变薄.这有利于解释超级单体的稳定持续发展和对流强度大而云层并不厚的观测事实. 通过对气压场调整的分析,可以认为水平旋转气流对垂直运动的作用是通过气压场的变更而实现的.
