Balance of Forces in the Atmospheric Boundary Layer,In this chapter, we divide the lower atmosphere into several sublayers, each with different degrees of turbulent mixing and different mechanisms of turbulence production.广告 发表于 2025-3-23 19:44:11
The Interstellar Medium,Although most of the mass of the Milky Way Galaxy is condensed into stars, interstellar space is not completely empty. It contains . and ., in the form both of individual clouds and of a diffuse medium. Interstellar space typically contains about one gas atom per cubic centimetre and one dust particle in 100000 cubic centimetres.defeatist 发表于 2025-3-23 23:26:33

Stellar Spectra,All our information about the physical properties of stars comes more or less directly from studies of their spectra. In particular, by studying the strength of various absorption lines, stellar masses, temperatures and compositions can be deduced. The line shapes contain detailed information about atmospheric processes.Obstruction 发表于 2025-3-24 15:23:05

Niere,Bei der histologischen Begutachtung von Nierenschnitten empfiehlt es sich, wenigstens im Anfang systematisch vorzugehen, um nicht wichtige, aber doch weniger auffällige Befunde zu übersehen. Zu diesem Zwecke betrachten wir immer hintereinander Glomeruli, Kanälchen und das Zwischengewebe mit den hier verlaufenden Gefäßen.完成才能战胜 发表于 2025-3-25 03:05:49
Photometric Concepts and Magnitudes,Most astronomical observations utilize electromagnetic radiation in one way or another. We can obtain information on the physical nature of a radiation source by studying the energy distribution of its radiation. We shall now introduce some basic concepts characterizing electromagnetic radiation.
