blue-violet light

In order to reveal the relationship between blue-violet light signal and the surface quality in cladding process, the blue-violet light signal intensity was measured in real time with a UV-420 device.

为了揭示熔覆时产生的蓝紫光信号与熔覆表面质量的关系，采用UV - 420对熔覆产生的蓝紫光信号强度进行实时检测。

Specifically, what is going on here is the Earth's atmosphere scatters light in the blue and violet wavelength range, so the remaining wavelengths of light appear yellow.

更准确一些的说，地球大气层把蓝色和紫色的波长范围进行散射，所以光线中剩下的波长就显现出了黄色。

Water refracts, or bends, the light, separating it into red, orange, yellow, green, blue, and violet

水把光线折射或弯曲，而分离为红、橙、黄、绿、蓝和紫色。
