In this paper we studied the intercalation behavior of a new host matrix of x = l of zirconium proline - n - mtthyl phosphonate - phosphate ( a - zpmpp ), we successfully introduced butylamine heptylamine decanylamine ethanolamine diethylenetriamine ( 2e3a ) triethyleneteriamine ( 3e4a ) and tetrathyleneoctamine ( 4e5a ) guest molecules into a - zpmpp interlayer space. the intercalation complex were characterized by ir spectrum x - ray diffraction and tg - dsc thermal analysis, it has been found that a - zpmpp possess different intercalation behavior from a - zrp. because of the bulk of proline group, it affected the amount of guest molecule, mono - alkylamine form mono - molecule layer in the interlayer space, butylamine, decanylamine and ethanolamine form mono - layer and the carbon chain form 90 degree ordered assembly with the zirconium floor of a - zpmpp, every host molecule absorbed 0. 5 guest molecule
本文報道首次以x ? l的層狀（脯氨酸十一甲基磷酸一磷酸氫）鉛（ a zpmpp ）為主體底物，成功地將客體分子：正丁胺、正慶胺、正癸胺、乙醇胺、二乙烯三股、三乙烯四胺、四乙烯五股插入層狀化合物a zpmpp的層間，通過紅外光譜（ ir ） 、 x射線衍射（ xrd ） 、熱重分析（ tg dsc ）等手段對插層復合物進行結構表徵，結果表明： x ? l的層狀（脯氨酸件一甲基磷酸一磷酸氫）鉛具有不同於無機磷酸結的插層性能，由於層間脯氨酸基團的體積較大，影響客體分子進入的數量，胺分子在層板間取單層排列。 -
Paper [ 76 ] provides a integer algorithm for rasterizing free curves, we need change the curve form to implicit function form, then use curve ' s positive - negative property to draw, but we ca n ' t use this algorithm when curve ' s degree is higher than 3 and this algorithm ca n ' t avoid using multiplication ; paper [ 77 ] provides a new generating algorithm, this algorithm can draw bezier very well, but for b - spline curve, we need use convert them into bernstein base form. because this process spends a lot of time, this algorithm has not a good speed and effect for rendering rational b - spline curve
現在經常採用的演算法也是基於幾何的演算法（即線式生成演算法）和基於像素的演算法（點式生成演算法） ;文獻78 ]提供了一種有理參數曲線的快速逐點生成演算法，該演算法對有理b吮ier曲線的繪制，能起到很好的作用，但是對于有理b樣條曲線，必須先通過多項式的代數基與bemstein基間的變換矩陣，把原式用bemstein基表示，這一過程由於計算量大，降低了曲線生成的速度和效率 -
For any weight w wn n n, the gauss - lobatto formula takes the following form which has algebraic degree of precision 2n - 1. these theorems have the adva
對於左閉的gauss - radau公式（對右閉的gau ， r 「 au公式，其結果是類似的，我們略去） ，我們首先獲得了一個一般性的結果，它把gauss . radau公式與gaus 。 -
In the forth chapter, we define a notion of the blossom for rational functional. existence and uniqueness property and dual functional property of the rational blossom are given. specially, the blossoming form for rational b ( ? ) zier curves of n degree is given
在第四章中，給出了關于有理函數的有理blossom的定義、唯一存在性以及對偶泛函性質；具體給出了二次有理b zier曲線的blossoming形式和一般n次有理b zier曲線的blossoming形式。
