The evacuation efficiency is influenced by different stressors like fire, earthquake, shooting and even evacuation drills. In this work, the single and collective evacuation experiments of empirical rodent were conducted under three stress levels (no stress, medium stress and high stress) from water. In individual experiments, the results indicate that high stress caused high-strung, whereas the evacuation time is longest under no stress condition. Compared with these two stress conditions, medium stress can generate stimulus but not high-strung for mice, which facilitates mice to evacuate more efficiently. In collective experiments, the mice interacted with each other during searching for the exit. Additionally, the higher stress makes mice more impatient, which can be observed from the frequent change of their movement directions when encountering others, and the medium stress conduces to the evacuation as well. The comparison of individual and collective behavior of mice can provide insight into interaction among pedestrians in a collective evacuation, and the findings are helpful for rapid and effective evacuation in emergencies.

洞察压力下单出口房间的疏散：小鼠实验

疏散效率受火灾、地震、射击甚至疏散演习等不同压力源的影响。在这项工作中，经验性啮齿动物的单个和集体撤离实验是在三个压力水平（无压力、中等压力和高压力）下从水中进行的。在个别实验中，结果表明高应力导致高弦，而在无应力条件下，疏散时间最长。与这两种应激条件相比，中等应激可以产生刺激，但不会对小鼠产生高度紧张，这有利于小鼠更有效地撤离。在集体实验中，老鼠在寻找出口的过程中相互交流。此外，更高的压力会使老鼠更不耐烦，这可以从他们在遇到他人时经常改变运动方向来观察，而中等应力也有利于疏散。小鼠个体和集体行为的比较可以深入了解集体疏散中行人之间的互动，研究结果有助于在紧急情况下快速有效地疏散。
