First, we introduce and discuss the various methods of multivariate polynomial interpolation in the literature. Based on this study, we state multivariate Lagrange interpolation over again from algebraic geometry viewpoint:Given different interpolation nodes A1,A2 .....,An in the affine n-dimensional space Kn, and accordingly function values fi(i = 1,..., m), the question is how to find a polynomial p K[x1, x2,...,xn] satisfying the interpolation conditions:where X=(x1,X2,....,xn). Similarly with univariate problem, we have provedTheorem If the monomial ordering is given, a minimal ordering polynomial satisfying conditions (1) is uniquely exsisted.Such a polynomial can be computed by the Lagrange-Hermite interpolation algorithm introduced in chapter 2. Another statement for Lagrange interpolation problem is:Given monomials 1 ,2 ,.....,m from low degree to high one with respect to the ordering, some arbitrary values fi(i= 1,..., m), find a polynomial p, such thatIf there uniquely exists such an interpolation polynomial p{X, the interpolation problem is called properly posed.

文中首先对现有的多元多项式插值方法作了一个介绍和评述，在此基础上我们从代数几何观点重新讨论了多元Lagrange插值问题：给定n维仿射空间K~n中两两互异的点A_1，A_2，…，A_m，在结点A_i处给定函数值f_i(i=1，…，m)，构造多项式p∈K[X_1，X_2，…，X_n]，满足Lagrange插值条件：p=f_i，i=1，…，m (1)其中X=(X_1，X_2，…，X_n)，与一元情形相似地，本文证明了定理满足插值条件(1)的多项式存在，并且按"序"最低的多项式是唯一的，上述多项式可利用第二章介绍的Lagrange-Hermite插值算法求出，Lagrange插值另一种描述是：按序从低到高给定单项式ω_1，ω_2，…，ω_m，对任意给定的f_1，f_2，…，f_m，构造多项式p，满足插值条件：p=sum from i=1 to m=Ai=f_i，i=1，…，m (2)如果插值多项式p存在且唯一，则称插值问题适定。

Later on, you may be told to return to the same location X and get object B, and quite likely even later to go to X and get object C. This is obviously not the shortest, quickest, or most efficient method. However, this type of longwinded description is hopefully the most logical, and should minimize the number of downright 'spoilers'.

稍后，你可能会被告知返回同一地点 X 和获得物体B和很可能，甚至后来到X和获得物体长这显然不是最短，最快捷，还是最有效的方法，但是，这种类型的longwinded描述希望是最合乎逻辑的，并应尽量减少人数，是彻头彻尾的'捣乱分子'。

Thus before undertaking Female Family Inbreeding / Linebreeding, the understanding of X-Chromosome and drawing correct of X-Chromosome are essential and breeders must determine a correct brood bitch for this purpose.

因此进行母系同种异系交配前，X染色体和绘制正确的X染色体图谱是必要的，繁殖者必须制作一个种母的图。

The results demonstrated that the dup(p21) and the del(p11) were of paternal origin and i was of maternal origin. The dup(p21) arose from an unequal sister chromatid exchange. The del(p11) occurred through X chromosom e breakage and deletion machanism.

结果表明，dup(p21)和del(p11)起源于父方，而i起源于母方。dup(p21)是由X染色体姊妹染色单体不均等的互换所引起的，del(p 11)是由于X染色体断裂后丢失所致，i的发生是由于卵母细胞X染色体着丝粒错分裂。
