摘要: 指出了一道量子力学习题解答的错误,并给出合理的解答,探讨了处于束缚定态的粒子对空腔内壁的平均作用力.

关键词: 束缚定态, 压力, 压强, 力的平均值, 力的方向

Abstract: A mistake in solving a quantum mechanics problem is pointed out,and a reasonable solution is also given. The average force of a particle in bound stationary state acting on the inner wall of a spherical cavity is discussed.

Key words: bounding stationary state, pressure, intensity of pressure, average value of force, direction of force
