These calculations can be compared with the chemical analyses of meteorites in an attempt to ascertain the conditions in the nebula at the time of their formations . 這些計(jì)算可與隕星的化學(xué)分析相比較,從而推斷在它們形成時(shí)星云中的條件。
The spherical particles are swept as droplets or volatilized and recondensed from a meteorite as it is heated to incandescence by friction in the upper atmosphere . 球形粒子是由小滴吹刮或者由在高層大氣中被摩擦加熱到白熾化的隕石揮發(fā)并重新凝結(jié)而成。
