见34#的实例。
原来的修正系数μ值的计算范围是【15亿,80亿】。
若把修正系数的μ缩小一点,则在20亿附近的计算值的精度会提高一些,但是下界计算式的下界范围则会缩小:
inf( 2022111100 ) = 1/(1+ .143 )*( 2022111100 /2 -2)*p(m) ≈ 4523520.7
inf( 2022111102 ) = 1/(1+ .143 )*( 2022111102 /2 -2)*p(m) ≈ 7605187.4
inf( 2022111104 ) = 1/(1+ .143 )*( 2022111104 /2 -2)*p(m) ≈ 3728477.7
inf( 2022111106 ) = 1/(1+ .143 )*( 2022111106 /2 -2)*p(m) ≈ 3207480.9
inf( 2022111100 )≈ 4523520.7 , jd ≈0.9979 ,infS(m) = 3204160.51 , k(m)= 1.41176
inf( 2022111102 )≈ 7605187.4 , jd ≈0.9978 ,infS(m) = 3204160.51 , k(m)= 2.37354
inf( 2022111104 )≈ 3728477.7 , jd ≈0.9976 ,infS(m) = 3204160.52 , k(m)= 1.16364
inf( 2022111106 )≈ 3207480.9 , jd ≈0.9980 ,infS(m) = 3204160.52 , k(m)= 1.00104
若μ缩小到0.14,则就会出现正的相对误差,不符合下界计算式的设定了。
inf( 2022111100 )≈ 4531449.8 , jd ≈0.99961 ,infS(m) = 3209776.93 , k(m)= 1.41176
inf( 2022111102 )≈ 7618518.2 , jd ≈0.99959 ,infS(m) = 3209776.93 , k(m)= 2.37354
inf( 2022111104 )≈ 3735013.2 , jd ≈0.99939 ,infS(m) = 3209776.94 , k(m)= 1.16364
inf( 2022111106 )≈ 3213103.1 , jd ≈0.99971 ,infS(m) = 3209776.94 , k(m)= 1.00104
inf( 2022111108 )≈ 6419553.9 , jd ≈0.99968 ,infS(m) = 3209776.94 , k(m)= 2
inf( 2022111110 )≈ 4279702.6 , jd ≈0.99935 ,infS(m) = 3209776.95 , k(m)= 1.33333
inf( 2022111100 ) = 1/(1+ .141 )*( 2022111100 /2 -2)*p(m) ≈ 4531449.8
inf( 2022111102 ) = 1/(1+ .141 )*( 2022111102 /2 -2)*p(m) ≈ 7618518.2
inf( 2022111104 ) = 1/(1+ .141 )*( 2022111104 /2 -2)*p(m) ≈ 3735013.2
inf( 2022111106 ) = 1/(1+ .141 )*( 2022111106 /2 -2)*p(m) ≈ 3213103.1
即使 μ缩小到0.141,计算的偶数稍微大些也容易出现正的相对误差,就不符合下界计算式设定的计算范围要求了:
inf( 2022111200 ) = 1/(1+ .141 )*( 2022111200 /2 -2)*p(m) ≈ 4279702.8
inf( 2022111202 ) = 1/(1+ .141 )*( 2022111202 /2 -2)*p(m) ≈ 3210861.1
inf( 2022111204 ) = 1/(1+ .141 )*( 2022111204 /2 -2)*p(m) ≈ 6528360.2
inf( 2022111206 ) = 1/(1+ .141 )*( 2022111206 /2 -2)*p(m) ≈ 3507268.6
inf( 2022111208 ) = 1/(1+ .141 )*( 2022111208 /2 -2)*p(m) ≈ 3504981.6
inf( 2022111200 )≈ 4279702.8 , jd ≈0.99974 ,infS(m) = 3209777.09 , k(m)= 1.33333
inf( 2022111202 )≈ 3210861.1 , jd ≈1.00031 ,infS(m) = 3209777.09 , k(m)= 1.00034
inf( 2022111204 )≈ 6528360.2 , jd ≈0.99984 ,infS(m) = 3209777.1 , k(m)= 2.0339
inf( 2022111206 )≈ 3507268.6 , jd ≈0.99981 ,infS(m) = 3209777.1 , k(m)= 1.09268
inf( 2022111208 )≈ 3504981.6 , jd ≈0.99912 ,infS(m) = 3209777.1 , k(m)= 1.09197
inf( 2022111210 )≈ 10302307.9 , jd ≈0.99977 ,infS(m) = 3209777.11 , k(m)= 3.20966

G(2022111208) = 3508078
G(2022111210) = 10304707
