Gap Transients Interacting with Circumstellar Medium

Universe, 2022
In the last 20 years, modern wide-field surveys discovered a new class of peculiar transients, which lie in the luminosity gap between standard supernovae and classical novae. These transients are often called “intermediate luminosity optical transients”

Study on the effect mechanism of CO on gas explosion reaction

Gong-kuang zidonghua, 2022
At present, most of the research on gas explosion takes the mixed gas of CH4 and air as the research object, but the gas explosion in coal mine is not a separate CH4 explosion, there are often CO and other components, which have a certain effect on gas ...

Powder Explosion Inhibitor Prepared from Waste Incinerator Slag: Applied to Explosion Suppression of Oil Shale Dust Explosion

Applied Sciences, 2022
In this paper, a method for waste incineration slag is proposed. An incineration acidification alkalization modification was carried out based on the characteristics of the oxides (SiO2, CaO, Al2O3, Fe2O3, and MgO) of waste incineration slag.
