旋臂

它们主要位于银河系（MilkyWay）等星系的旋臂和年轻星团中。

They mostly inhabit the spiral arms and younger parts of galaxies like the Milky Way .

适当地调节参量ΩP和B（m，n），计算得到的理论曲线与实际观测到的旋臂符合较好。

Adjusting the para - meters Ω _p and B ( m , n ) appropriately , the theoretical curves calculated coincide with the observational spiral arms , and the Larger differences between them appearing sometimes in C. C.
