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.

与背景气体发生粘滞碰撞时，动能沉积到纳米液滴，团簇或分子中

在过程中，当诸如纳米液滴，团簇或分子之类的颗粒穿过稀薄的背景气体并发生捕获碰撞时，了解这些拾取事件将多少平移动能沉积到颗粒中通常很重要。对于与麦克斯韦-玻尔兹曼气体的粘滞碰撞，可以得出一个精确的表达式，该表达式对于任意相对大小的粒子和热气体速度都是有效的。
