2019年12月4日 · Thorlabs' Integrating Spheres are general-purpose devices for high sensitivity measurements of optical signals. An integrating sphere evenly spreads the incoming light by multiple reflections over the entire sphere surface. This makes it the ideal instrument for many applications such as laser power, flux, reflectance, and radiance measurements.

今天我们来讲一下原子核外电子的排布，那么电子的排布需要服从以下四个原则： （1） Puali‘s Exclusion Principle （保利不相容原理）：每个轨道最多只能容纳两个电子，且自旋方向相反。 （2） Lowest Energy Pri…
