So, if you're using the wavefunction to describe your electron as a wave, you can know its exact momentum.

因此,如果您使用波函数将电子描述为波,您可以找出它的确切速度。

202325

The wavefunction could only yield the probabilities of finding a particle in different states, reflecting the inherent uncertainty in predicting specific outcomes in quantum measurements.

波函数只能得出找到处于不同状态的粒子的概率,反映了预测量子测量中特定结果的固有不确定性。

设想经典力学里的谐振子 系统(A-B),一条弹簧的一端固定不动,另一端有一个带质量圆球;在量子力学里, (C-H)展示出同样系统的薛丁格方程序的六个波函数解。横轴坐标表示位置,竖轴坐标表示波函数机率幅的实部(蓝色)或虚部(红色)。(C-F)是定态,(G、H)不是定态。定态的能量为驻波振动频率与约化普朗克常数的乘积。

在一维无限深方形阱内,粒子的能级与对应的波函数。
在这篇文章内,矢量与标量分别用粗体与斜体显示。例如,位置矢量通常用\mathbf{r}\,\!表示;而其大小则用r\,\!来表示。

在量子力学里,量子系统的量子态可以用波函数英语:wave function)来描述。薛丁格方程序设置波函数怎样随着时间流易而演化。从数学角度来看,薛丁格方程序乃是一种波动方程序,因此,波函数具有类似波的性质。这说明了波函数这术语的命名原因。

波函数 \Psi (\mathbf{r},t) 是一种复值函数,表示粒子在位置 \mathbf{r} 、时间 t 的机率幅,它的绝对值平方 |\Psi(\mathbf{r},t)|^2 是在位置 \mathbf{r} 、时间 t 找到粒子的机率。更宽松地诠释,波函数\Psi (\mathbf{r},t)是「在某时间、某位置发生相互作用的概率幅」。

波函数的概念在量子力学里非常基础与重要,很多关于量子力学诠释的谜一般的后果与困惑,都源自于波函数,甚至今天,这些论题仍旧尚未获得满意解答。

Wave function 波函数

(重定向自Wavefunction)
Comparison of classical and quantum harmonic oscillator conceptions for a single spinless particle. The two processes differ greatly.

The classical process (A–B) is represented as the motion of a particle along a trajectory. The quantum process (C–H) has no such trajectory. Rather, it is represented as a wave. 
Panels (C–F) show four different standing wave solutions of the Schrödinger equation. Panels (G–H) further show two different wave functions that are solutions of the Schrödinger equation but not standing waves.
Standing waves for a particle in a box, examples of stationary states.Travelling waves of a free particle.The real parts of position wave function Ψ(x) and momentum wave function Φ(p), and corresponding probability densities |Ψ(x)|2 and |Φ(p)|2, for one spin-0 particle in one x or p dimension. The colour opacity of the particles corresponds to the probability density (not the wave function) of finding the particle at position x or momentum p.
Traveling waves of two free particles, with two of three dimensions suppressed. Top is position space wave function, bottom is momentum space wave function, with corresponding probability densities.

A wave function in quantum mechanics is a description of the quantum state of a system. The wave function is a complex-valued probability amplitude, and the probabilities for the possible results of measurements made on the system can be derived from it. The most common symbols for a wave function are the Greek letters ψ or Ψ (lower-case and capital psi).
