在纳米液滴、团簇或分子等粒子通过稀薄的背景气体并经历俘获碰撞的过程中，了解这些拾取事件向粒子沉积了多少平动动能通常是很重要的。对于与Maxwell-Boltzmann气体的粘合碰撞，导出了一个对粒子速度和热气体速度的任意相对大小都有效的精确表达式。
In processes when particles such as nanodroplets, clusters, or molecules move through a dilute background gas and undergo capture collisions, it is often important to know how much translational kinetic energy is deposited into the particles by these pick-up events. For sticking collisions with a Maxwell-Boltzmann gas, an exact expression is derived, which is valid for arbitrary relative magnitudes of the particle and thermal gas speeds.
