what IS EMISSION
Let us first explain the most basic "emission" phenomenon in the real world: there are many electrons in each atom or molecule, and these electrons can be found at various energy levels. In order for an electron to move from a lower energy level to a higher energy level, it needs to receive energy from the outside. But an electron can go from a higher energy level to a more stable lower energy level required by the law of "conservation of energy" and emit photons (light packs) around it. The frequency of these photons creates the emission spectrum. Some of them are visible in the visible range (400-700 nanometer wavelength) so, we can see them with bare eyes.
什么是发光
让我们首先解释一下现实世界中最基本的“发射”现象:每个原子或分子中都有许多电子,并且这些电子可以在各种能级下找到。 为了使电子从较低的能级移动到较高的能级,它需要从外部接收能量。 但是,电子可以从“能量守恒定律”所要求的更高能量水平变为更稳定的更低能量水平,并在其周围发射光子(轻型电池组)。 这些光子的频率产生发射光谱。 其中一些在可见范围(400-700纳米波长)内可见,因此,我们可以用裸眼看到它们。

Emission in Octane means using any object as a light source (Temperature with Kelvin). In doing so, it simply formulates a natural phenomenon called "Blackbody Radiation" under the name "Blackbody Emission". Thus, any object in your scene becomes a light source. Now we can explain "Blackbody Emission" in more detail.
Octane的发射是指使用任何物体作为光源(开尔文温度)。 这样,它只是以“黑体辐射”的名义简单地表达了一种自然现象,称为“黑体辐射”。 因此,场景中的任何对象都将成为光源。 现在我们可以更详细地解释“黑体发光”。
