但对于非线性速度分布的连续射流，存在的虚拟原点不是唯一的。

But for the continuous jet which velocity gradient is not linear, it has not only one virtual origin.

对于沿射流长度方向具有线性分布速度的连续射流，经典的基于虚拟原点理论的射流侵彻关系式能很好的描述其侵彻行为。

The classical penetration equation based on the virtual origin theory can well describe the penetration behaviour of the continuous jet with linear velocity distribution.

磁流变液完全屈服时，磁流变液角速度随半径呈非线性增加，工作间隙中磁场越强，流场的非线性分布越明显；

When the MRF wholly yields, the angular velocity of MRF increases nonlinearly with its radius, the non-linear distribution becomes more obvious as the magnetic intensity in the working gap increases.
