太阳系角动量掉队星云环Solar System Angular Momentum Fall behind Nebular Rings

摘要:

以往星云说,用可压缩流体的临界自转角速度公式去确定原始星云初始的角动量数值,是误导。因为原始星云转动快慢还不知道呢,怎么就把它当作临界自转去计算呢。本文推导出计算公式,对星云盘物质角动量进行定量计算,证明原始星云初始角动量不大,靠惯性离心力形成不了星云盘。角动量不足的原始星云掉队形成了太阳系,再次复述了拉普拉斯的星云环论点的假设。太阳系原始星云角动量密度分布不均匀,形成了太阳系角动量分布的特征。我们发现了太阳系环体物质的中聚规律和太阳系逆行卫星的形成。

Nebular theories used to work out the value of initial angular momentum with a critical rotation angular velocity formula of compressible fluid, which is considered misleading. People even don’t know how fast or slow primitive nebula rotates, what chance do they solve it as critical rotation? We quantitated angular momentum of matter in the nebular disc by the inferred calculation formula in an attempt to prove that the primitive nebula conserves so low angular momentum that the nebular disc would never be formed by inertial centrifugal force only. The primitive nebula with insufficient angular momentum fell behind to form the solar system. Laplace’s hypothesis on nebular rings was revived. The density of angular momentum unevenly distributing in primitive nebula of the solar system featured distribution of the angular momentum of the solar system. We discovered the law that matter accumulates in middle of rings of the solar system and found out the source where matter flow of the solar system comes from in opposite direction.
