| 摘 要： | 本文讨论了日冕膨胀中的角动量问题。利用大量I型彗尾资料的计算,证实了日冕膨胀中方位分量的存在;它不仅是随机量,而是具有大小为9.8km/s的定常量。太阳演化到主序星阶段以来,由于日冕膨胀丢失了80％的角动量,太阳自转角速度正以指数律下降。因此,这将对太阳动力演化起到很大的影响。

| 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. |
