Collection of Stratospheric Microparticles Above the Sulfate Layer Using Balloon-Borne Collectors34–36 km altitude. The particles are predominantly silica, plagioclase feldspar, Mg, Fe-silicates and rare barite, metal oxides, and unidentified Fe, Ni, Zn, and Pb particles. The majority of these generally submicron-sized particles are comparable to volcanic particles collected at 20 km altitude fSmall-Intestine 发表于 2025-3-30 15:15:38

Physical and Mineralogical Properties of Anhydrous Interplanetary Dust Particles in the Analytical Enumerous electron microscopic studies. The “pyroxene” interplanetary dust particles (IDPs) are porous, unequilibrated assemblages of mineral grains, metal, glass, and carbonaceous material. They contain enstatite whiskers, FeNi carbides, and high-Mn olivines and pyroxenes, all of which are likely toKIN 发表于 2025-3-31 01:24:38

Point potentials scatter only .-waves and do not influence waves with higher orbital momentum. Therefore they lift the infinite degeneracy of the Landau levels only partially. As a result the spectrum can be divided into two parts: the set of discrete L
