The main work is as followings: First, we use KE SI DA microscope for observing the appearance and configuration of bicomponent fiber. It was found in the bicomponent fiber it is a bilateral array for the PET and PTT. The cross section is anisomerous with PTT and PET side by side. After heat treating the shape of single filament becomes three dimensional curly and the number of crimp is biggest in the condition of relaxation. In the range of some tention, the bulkiness and crimpness fall obviously after the bicomponent fiber is treated with heat.

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.
