Calcium montmorillonite was prepared by purifying LeXi bentonite with wet method two times. After purification, sodium modification of Ca-M was studied. A series of Fe/Cr-pillared montmorillonites were prepared with conventional method using sodium montmorillonite as experimental materials, and synthesis condition of Fe/Cr-PILM was studied and optimized. In order to shorten the preparation cycle of PILM by overleaping the step of sodium modification of Ca-M, the pretreatment technique for Ca-M has been pointed out for the first time. A series of PILMs were prepared with hydrothermal method using pretreated Ca-M as starting materials, which show that pretreatment of Ca-M is feasible.

This paper studied the relationship between impulsive moment of radial tidal current and Alai phenomena, and concluded that: M acting on the earth's axis inspires Chandler wobble; the change of M depends on the interaction of the water, tidal force and the effects of the earth's rotation; under certain conditions, M changes dramatically during eclipse, which makes the amplitude of Chandler wobble change in the form of pulse.

本文研究了径向潮流冲量矩M与阿莱现象的关系，得出的结论是：M作用于地轴激发了Chandler摆动；M的变化取决于海水、引潮力和地球自转效应的相互作用；日食或月食期间，在一定的条件下，M变化的非常剧烈，引起Chandler摆动振幅脉冲式的变化，进而引起地球纬度的变化，最终导致地球表面重力加速度的变化；这种变化可以通过傅科摆摆动平面角速度的变化或重力计的示数变化反映出来。

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.
