In the study of circuit detection scheme for the low-cost Fiber Optic Gyroscope (FOG), a closed-loop scheme for analog demodulation, square wave modulation and step wave feedback was put forward.

针对低成本光纤陀螺的电路检测方案开展研究，提出一种模拟解调、方波调制和阶梯波反馈的闭环方案。

So, that's probability density, but in terms of thinking about it in terms of actual solutions to the wave function, let's take a little bit of a step back here.

这就是概率密度，但作为,把它当成是，波函数的解，让我们先倒回来一点。

So, we'll take a little bit of a step back after we introduce quantum mechanics, and talk about light as a wave, and the characteristic of waves, and then light as a particle. And one example of this is in the photoelectric effect.

等我们介绍完量子力学后,我们要回过头来讨论下光,作为一种波和它的波动性特征,以及光作为一种粒子,其中的一个粒子就是光电效应。
