The Magnetic Field Structure in M81The HI spiral arms follow a logarithmic spiral pattern of pitch angle −15° [2] close to the pitch angles of the optical spiral arms [3] and those of the blue light and Ha (−12°±2°, [4]). The theory of density waves has been applied successfully to explain the clear two-armed spiral structure of M81

α‘ /β’ Sialon Compositeshile that of β’-sialon did not. The amount of α’-sialon decreased with increasinq sinterinq temperature. This phenomenon was observed when Si.N.. ceramics containinq α’-sialon were heated at hiqher temperatures for a lonq time. From these results, it is concluded that when α’-sialon coexists with β’-sialon, it is a metastable at hiqh temperatures.
