粒子运动

The interior flow field of the deep－well pump is studied with Particle Image Velemetry technology. The effects of flow field on motion rule of valve and the effects of interior structure on flow field are analyzed.

林盛应用粒子成像测速技术对深井泵泵内流场进行了研究，分析了流场对泵阀运动规律的影响以及泵内结构对流场的影响。

These clumps may act like super-sized particles, changing the way the rings spread due to collisions.

团块的举止很可能像超大粒子，通过碰撞改变运动方向并扩展为光环整体。

Thus anisotropies observed in the final state are built up early and in the hottest stages of the collision, as the cause of these anisotropies disappears during the system's evolution.

在初始碰撞重叠区域的短轴方向上会产生较大的压强差，而使更多的粒子向这一方向上运动并逐步减小长、短轴方向上的差别。

If one single particle collides with another single particle, their motions should obey both energy and momentum conservations.

两个单粒子的碰撞运动，既要服从能量守恒，又要服从动量守恒。

However, we can measure just the position alone of a moving free particle creating an eigenstate of position with a wavefunction that is very large at a particular position x, and zero everywhere else.

然而，我们可以仅单独测量一个运动的自由粒子的位置用多数情况下特别位置X和零其它地方的一波函数来产生一个特征态。

Some results such as the potential distribution in the gun, the trace-space plot of ray in anode plane, the impact on beam focusing caused by the spacing of diode were obtained.

计算程序以带电粒子的洛伦兹力运动方程的相对论形式为基础，在充分考虑了空间电荷效应和电子自身产生磁场的情况下编写而成。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
