我们实验证明了避免交叉耦合两个谐振子。每个谐振子由一个通过弹簧连接到固定壁的质量组成。两个谐振子通过连接两个质量的弹簧耦合。避免交叉实验证明在两种方式：首先，通过调整一个振荡器的弹簧常数，然后通过单独调整振荡器的质量。在这两种情况下，对于第二振荡器，调整后的参数保持恒定。此外，我们研究了改变两个振荡器之间的耦合的影响。这些实验结果与理论预测一致。我们在实验上证明了通过耦合两个谐振子可以避免交叉。每个谐振子由一个通过弹簧连接到固定壁的质量组成。两个谐振子通过连接两个质量的弹簧耦合。避免交叉实验证明在两种方式：首先，通过调整一个振荡器的弹簧常数，然后通过单独调整振荡器的质量。在这两种情况下，对于第二振荡器，调整后的参数保持恒定。此外，我们研究了改变两个振荡器之间的耦合的影响。这些实验结果与理论预测一致。
We experimentally demonstrate an avoided crossing by coupling two harmonic oscillators. Each harmonic oscillator consists of a mass connected to a stationary wall by a spring. The two harmonic oscillators are coupled by a spring connecting the two masses. An avoided crossing is experimentally demonstrated in two ways: first, by adjusting the spring constant of one oscillator, and then by separately adjusting the mass of the oscillator. In both cases, the adjusted parameter is held constant for the second oscillator. Additionally, we examine the effects from altering the coupling between the two oscillators. These experimental results are shown to be consistent with theoretical predictions.We experimentally demonstrate an avoided crossing by coupling two harmonic oscillators.
