我们讨论了波包通过相互作用的环境中的传播。这样的环境通常会改变波函数的色散关系或形状。为了详细研究这种效应，我们定义了分布函数${P}_{X}（T），$它描述了数据包到达位于点X的检测器的时间T。我们计算了波包通过隧穿势垒时的P_X（T），发现我们的结果实际上解释了最近的实验。我们比较我们的结果与纳尔逊的量子力学的随机解释，并解决了一个悖论以前明显的纳尔逊的观点的隧道时间。
We discuss the propagation of wave packets through interacting environments. Such environments generally modify the dispersion relation or shape of the wave function. To study such effects in detail, we define the distribution function ${P}_{X}(T),$ which describes the arrival time T of a packet at a detector located at point X. We calculate ${P}_{X}(T)$ for wave packets traveling through a tunneling barrier and find that our results actually explain recent experiments. We compare our results with Nelson's stochastic interpretation of quantum mechanics and resolve a paradox previously apparent in Nelson's viewpoint about the tunneling time.
