The results indicate that the penetration depth does not increase with the increasing hit velocity, which is different from the phenomena of the penetration of concrete and rock.
这与弹体在普通混凝土和岩石中的侵彻现象明显不同，主要是由侵彻弹体发生破坏失去了继续侵彻能力造成的。

It shows that the effects of back pressure on penetration, spray cone Angle, and decline rate of centerline velocity and concentration of the spray are greater than that of fuel injection pressure.
背压对贯穿距离、喷雾锥角、喷雾轴心速度和浓度衰减率的影响均大于启喷压力。

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