摘要
论证一行《大衍历》（Ａ．Ｄ．７２９）的二次不等间距插值法和刘焯《皇极历》（Ａ．Ｄ．６０４）的二次等间距插值法的实质完全相同，并没有一般所说的推广意义；否定了以往人们关于一行有意识地应用了三次插值法近似公式的说法．
In this paper,it is described that the substance of the second order interpolation with unequal steps. used in YiXin's Deyan calendar (A.D.729),is the same as the one with equal steps used in the Huangji calendar(A.D.604,compiled by Liuzhuo).It is also pointed out that it can't be confirmed that the interpolation of the third order was used by YiXin.
