Abstract

Abstract

In the paper,the feature of angular momentum in the coronal expansion is discussed.According to the calculation of data on the Type-I cometary tails,the tangential component of coronal expansion is verified;not only it has a stochastic change,but also it has a confirmed value (9.8km/s).Since the solar evolution reached to the main sequence stage,the sun lost the 80% of its angular momentum,thus the angular velocity of its rotation is reducing by the power index law.
