不确定性原理(Uncertainty Principle)是量子力学中的核心理论之一,由德国物理学家维尔纳·海森堡于1927年首次提出。该原理指出:在微观粒子系统中,某些成对的物理量(如位置与动量、能量与时间)无法同时被精确测量。当其中一个量的测量精度提高时,另一个量的不确定性必然增大。
从数学表述来看,位置($Δx$)和动量($Δp$)的不确定性满足关系式:
$$
Δx cdot Δp geq frac{hbar}{2}
$$
其中$hbar$为约化普朗克常数。这一公式表明,粒子的位置越精确,其动量的不确定性就越大,反之亦然。

不确定性原理(Uncertainty Principle)是量子力学中的核心概念之一,由德国物理学家维尔纳·海森堡于1927年提出。以下是其详细解释:
该原理指出:在量子系统中,某些成对的物理量(如位置和动量、能量和时间)无法被同时精确测量。例如,粒子的位置测量越精确,其动量的不确定度就越大,反之亦然。这一限制并非源于测量技术的缺陷,而是量子系统本身的固有特性。
海森堡不确定性关系的数学形式为: $$ Delta x cdot Delta p geq frac{hbar}{2} $$ 其中:
类似的关系也适用于能量与时间:( Delta E cdot Delta t geq hbar/2 )。
该原理颠覆了传统决定论世界观,成为量子力学区别于经典物理的标志性理论之一。
