1 Introduction Thermospheric mass density is an essential parameter in the earth's thermosphere and can cause atmospheric drag force on Low-Earth orbit (LEO) satellites. As a typical non-conservative force, atmospheric drag is the fundamental perturbation source of satellites, and it has a constant and considerable effect on the satellites, such as orbit determination, collision warning, and motion safety (Doornbos, 2012).

1. IntroductionThe process and mechanism of gold mineralization are the frontiers of gold deposit research and are essential for understanding the genesis of the deposits and establishing the mineralization models [1,2,3,4,5]. Pyrite is the most common gold-bearing sulfide and is also an important host to a range of trace elements such as Au, Ag, Cu, Pb, Zn, Co, Ni, As, Sb, Se, and Te, which are useful indicators for ore genesis and physico-chemical conditions [6,7,8,9,10,11,12,13,14].
