        =43.956808+(-2.868296)×0.001×418.83+3/2×2.3482926×0.000001×175418.568899999983842
        =43.956808+(-0.002868)×418.83+3/2×2.3482926×0.000001×175418.568899999983842
        =43.956808+(-1.201204)+3/2×2.3482926×0.000001×175418.568899999983842
        =43.956808+-1.201204+1.5×2.3482926×0.000001×175418.568899999983842
        =43.956808+-1.201204+3.522439×0.000001×175418.568899999983842
        =43.956808+-1.201204+0.000004×175418.568899999983842
        =43.956808+-1.201204+0.701674
        =42.755604+0.701674
        =43.457278
    答案:7.280673*ln418.83+2×-1.434148×10^(-3)×418.83+3/2×2.3482926×10^(-6)×(418.83)^2=43.457278
