1) scale factor of the universe
宇宙标度因子
1.
By substituting the scale factor of the universe,a(t),into the cosmic-dynamical equations derived from modified gravity with undetermined additional terms,then expanding the resultant equations in.
把宇宙标度因子a(t)代入由含待定修正项修正引力导出的宇宙动力学方程,并在t=t0处展开为Taylor级数,保留前2项,定出引力拉氏量中修正项的系数,从而把修正项置于更为可靠的基础上。
2) cosmological factor
宇宙因子
1.
The equation obtained in the derivative process shows that,it is necessary to introduce a scalar function as the cosmological factor into the gravitational equation in order to quantize canonically the gravitational filed.
推导过程中得到的公式表明,为了把引力场正则量子化,给引力场方程引入一个标量函数作为宇宙因子是必要的。
