This paper by Eisenstein and Criterion On a few of the conclusions presented several integer coefficients irreducible polynomials way of judging, but the discussion of not more than four times the whole of the polynomial coefficients can be about issues, by some three to four times the entire polynomial coefficient about the summary judgment method.

"The biggest hurdle that I have to overcome is making people believe that even though I am a woman, I am a serious contender," Riley said."I have to remind people that I have competed in two Whitbread races and this is my third America's Cup. I have seen what happens behind the scenes, and I know what it takes to get things done in this kind of environment."

The result indicates that conicoid anti error is smaller than that of plane and three cubed anti error fitting model, but the validity of the model doesn't necessarily have relationship with model steps.

结果 二次曲面抗差的结果要好于相关平面与三次曲面抗差的结果精度，并非抗差模型阶次越高有效性越高。
