我国与西方国家地方税制的比较分析

构建地方税收体系是地方政府相对独立性的客观要求，能够起到激励地方政府经济行为的作用，符合市场经济条件下政府分权的需要。在地方税制建设和中央、地方政府间税权的划分上，西方国家有较成熟的经验，通过比较分析，可以借鉴其精华为我所用。

Continued Fraction Algorithm for Matrix Exponentials

A recursive rational algorithm for matrix exponentials was botained by making use of the generalized inverse of a matrix in this paper.On the basis of the n-th convergence of thiele-type continued fraction expansion,a new type of the generalized inverse matrix-valued pade approximant(GMPA)for matrix exponentials was defined and its remainder formula was proved.The resuts of this paper were illustrated by some examples.     

周期连分数的快速逼近

本文采用连分法得到描述分子晶体中分子之间的相互作用势V(r)=Atr-10-A2r-6+A3r2(A1,A2,A3＞0)的分子晶体的Hamiltonian算子的精确的能量本征值和能量本征函数.     

连锁与交换规律计算问题的研究

针对连锁与交换规律的计算问题,提出了一组完整、严密、科学的计算公式。1 当无双交换或更高数目的偶数交换时,则:重组率=交换值=图距%=重组合表型的百分率。2 当有双交换或更高数目的偶数交换时,则:单交换Ⅰ(或单交换Ⅱ)的重组率=单交换Ⅰ(或单交换Ⅱ)的交换值=图距%;单交换Ⅰ(或单交换Ⅱ)表型(或配子)的百分率=单交换Ⅰ(或单交换Ⅱ)的重组率-双交换表型的百分率-更高数目的偶数交换表型的百分率;两端基因的交换值=单交换Ⅰ的重组率(或交换值)+单交换Ⅱ的重组率(或交换值)=单交换Ⅰ表型(或配子)百分率+单交换Ⅱ表型(或配子)的百分率+2×双交换表型的百分率或更高数目的偶数交换表型的百分率=图距%。     

线性同余随机数列二维结构的快速算法

在给出线性同余(LCG)随机数列平行直线族精确表达式的基础上，证明计算LCG最少平行线条数和谱检验法，都为对分数A／M的渐近分数及其相邻渐近分数插值的比较，并提出LCG二维结构的快速算法。     

Determination of the volatile fraction of coal tar

The coal tar was qualitative and quantitative anMyzed by gas chromatography （GC） method. 74 components were identified exactly by gas chromatographY-mass spectrometry （GC-MS）. 31 components （37%） were quantitatively analyzed by gas chromatography-flame ionization detector （GC-FID）. The linearity, accuracy, precision, limit of detection （LOD） and limit of quantitative （LOQ） determination were inspected. The scope of quantitative analysis by CC was discussed. The experimental results of thermogravimetric analysis （TGA） proved that GC quantitative analysis of the coal tar was reliable.     

Progress in Literacy Coaching Success—A Dozen Years on

Literacy coaches are most successful when they: develop strong, trusting relationships; provide clarity about their roles; communicate well; spend much of their time in coaching conversations; and monitor their perspectives about their work and those with whom they work. However, challenges still persist for literacy coaches, particularly in relation to administrators' understanding of literacy coaching, training for literacy coaches, and the amount of time allocated for literacy coaching. This article describes each of these successful practices and each of these challenges, based upon the author's experience over more than 12 years as an international consultant on literacy coaching and supported by research from the literature on coaching, with the goals of summarizing current knowledge, providing practical suggestions for improvement, and encouraging forward movement in the field of coaching.
