infrared illumination
1.Proceed from energy-conserving angle, utilize infrared device and intensity of illumination count and auxiliary circuit make up "classroom light systematic intellectual control" device far.
2.We present H and K s polarimetric images in a ～5′ field of star forming region NGC7538. The polarimetric images reveal the complex structure of infrared nebulosities and clusters of young stars, associated with the bright infrared sources IRS 1 11. The polarization pattern in the IRS 1 3 nebula shows a dominant illumination from deeply embedded source IRS 1. The morphology of the nebula can be modeled by a low extincted bubble enclosed by redder and highly polarized shell.
3.Although no one can ever imagine spending 1,000 years observing the process of the changes, science can nevertheless design color changing simulation experiments, including the simulation of the illumination by sunlight, ultraviolet light and infrared light in different sampling humidifiers placed in an environment of harmful gases such as carbon dioxide, hydrogen sulfide, and ozone.
