宇宙模型 meaning in English
cosmological model
Examples
- We find that the cosmic scale factor has the form of exponent inflation if the cosmological constant contributes to the positive material density , and the factor is composite function of cosine if the cosmological constant contributes to the negative material , furthermore , we gain the new formality of the pressure and the temperature in the procedure of cosmological evolution
首次发现当宇宙学常数对物质密度的贡献大于零时有指数复合函数的型得一般暴涨,当宇宙学常数对密度的贡献小于零时宇宙有余弦形式的演化。通过对宇宙中压强和温度的计算,得到新的压强表达式和暴涨宇宙模型中温度随时间演化的表达式。 - The exact solution of the einstein field equation is gained under the popular conditions when , the new general expression of the density function is deduced . , the new solution of the cosmic scale factor is further derived out under different evolution model
求解了当时一般情况下标准宇宙模型方程,通过一般地求解不同密度物质情况下的暴涨宇宙演化方程,得到了的一般物质密度的表达式,解出了表征宇宙标度因子不同演化的一般新解,并通过对不同情况下标准宇宙方程的求解,证明参数的正负取值直接影响宇宙尺度因子的表达形式。
