补充资料：态叠加原理
| 态叠加原理 state，superposition principle of 量子力学的基本假设之一 ，可表述为如果波函数Φ1、Φ2、…Φn是描写微观粒子体系的可能状态，则它们的线性叠加c1Φ1＋c2Φ2＋…cnΦn也是粒子体系的一个可能的状态，式中c1、c2、…cn是常数。电子双孔干涉实验（见波粒二象性）是态叠加原理的一个特例，电子通过双孔的态是Φ1＋Φ2，电子在屏上的概率分布在｜ Φ1＋Φ2 ｜2＝｜Φ1｜2＋｜Φ2｜2＋Φ1*Φ2＋Φ1Φ2*，Φ*是Φ的共轭函数，式中后两项体现双孔干涉的效果。态叠加原理表明微观粒子体系是线性系统，它所遵从的运动方程是线性方程。态叠加原理还是表象理论的基础。 |
