One reason to believe dark matter exists is that galaxies rotate at such speeds that they would fly apart without it, or so the argument goes. - 为了研究引力不稳定性在巨分子云形成中的作用,通过计算机模拟技术建立了星系中分子云的较差自转模型。
Based on the thermodynamic models of the mantle, the thermodynamic unstability conditions and critical conditions of the mantle under the influence of numerous factors are analysed.
