r圆半径
g=GM/R^2 a圆=GM/r^2= GM/(3R)^2 =g/9
T圆=2π√(r/a圆)=2π√[3R/(g/9)]=10.4π√(R/g)
T椭^2/T圆^2=[(3R+R)/2]^3/(3R)^3=(2R)^3/(3R)^3=(2/3)^3
T椭/T圆=[(3R+R)/2]^3/(3R)^3=(2R)^3/(3R)^3=(2旦互测就爻脚诧协超茅47;3)^(3/2)
T椭=[(3R+R)/2]^3/(3R)^3=(2R)^3/(3R)^3=(2/3)^(3/2)T圆=0.544T圆
T圆-T椭=(1-0.544)T圆=4.7π√(R/g)
2R是椭圆的半长轴 (3R+R)/2=2R
