解读《少年Pi的奇幻漂流》的后现代主义写作特点

扬·马特尔的名作《少年Pi的奇幻漂流》是一个关于一艘孤船、一位落难少年,加上一只孟加拉虎在南太平洋上接受最艰难的生存考验的故事。用后现代主义文学批评理论来解读这部小说的话,书中关于少年的名字P(iπ)的选取、故事的多重多元讲述者、历险记的多版本结局设置、Pi自身对于宗教的认知与理解无不渗透着后现代主义写作特点的深刻烙印。该文试图从后现代主义写作特点的角度来解读小说,以期让读者从深层次更好的理解这个看似简单的历险记中的层深寓意。     

特别的能力——浅谈Pirouetté的训练

在芭蕾舞中,"旋转"占有重要的位置.它是舞蹈语言中令人肯定的组成部分,不同速度的"旋转"可以表达舞者的不同情感,因此"旋转"的训练在芭蕾基训中起着至关重要的作用.

Shape modification of Bézier curves by constrained optimization

The Bézier curve is one of the most commonly used parametric curves in CAGD and Computer Graphics and has many portant problem, and is also an important research issue in CAD/CAM and NC technology fields. This work investigates the curves to satisfy the given constraints and modify the shape of the curves optimally. Practical examples are also given.     

A quadratic programming method for optimal degree reduction of Bézier curves with G1-conitnuity

This paper presents a quadratic programming method for optimal multi-degree reduction of Bézier curves with G1-continuity. The L2 and l2 measures of distances between the two curves are used as the objective functions. The two additional parameters, available from the coincidence of the oriented tangents, are constrained to be positive so as to satisfy the solvability condition. Finally, degree reduction is changed to solve a quadratic problem of two parameters with linear constraints. Applica     

A class of quasi Bézier curves based on hyperbolic polynomials

This paper presents a basis for the space of hyperbolic polynomials Γm=span{ 1, sht, cht, sh2t, ch2t, ..., shmt, chmt} on the interval [0,α] from an extended Tchebyshev system, which is analogous to the Bernstein basis for the space of polynomial used as a kind of well-known tool for free-form curves and surfaces in Computer Aided Geometry Design. Then from this basis, we rameter variable t to arbitrary close interval [r, s] (r＜s).     

PH-spline approximation for Bézier curve and rendering offset

In this paper,a G1, C1, C2 PH-spline is employed as an approximation for a given Bézier curve within error bound and further renders offset which can be regarded as an approximate offset to the Bézier curve. The errors between PH-spline and the Bézier curve, the offset to PH-spline and the offset to the given Bézier curve are also estimated. A new algorithm for constructing offset to the Bézier curve is proposed.     

《少年Pi的奇幻漂流》的精神分析理论解读

精神分析电影理论是当代电影理论中极其重要的部分,在相当程度上改变了电影理论与批评的研究方向与思略。第二电影符号学、女性主义电影理论的产生都是围绕着弗洛伊德所开启的精神分析学说以及拉康的镜像理论而展开的。本文将运用精神分析电影理论对李安导演的《少年Pi的奇幻漂流》作一分析和解读。

碱金属卤化物物理化学性质Pi的QSPR研究

物理化学性质在无机化学领域中发挥重要作用，由于无机化合物种类繁多，人们不可能逐个测定其物理化学性质Pi，现有的数据又不能满足实际应用的需要，因此建立直观、简单的定量结构与性质的构效关系(QSPR)法用于计算和预测某些化合物的物理化学性质Pj，是一项十分有意义的工作，在OSPR研究中，分子拓扑指数法扮演重要角色，成为21世纪化学研究的前沿领域 。     

Improvement of the termination criterion for subdivision of the rational Bézier curves

By using some elementary inequalities, authors in this paper makes further improvement for estimating the heights of Bézier curve and rational Bézier curve. And the termination criterion for subdivision of the rational Bézier curve is also improved. The conclusion of the extreme value problem is thus further confirmed.     

Least-squares function-valued Padé-type approximation and its application in solving integral equations

To solve the Fredholm integral equations of the second kind,a new notion of the least-squares orthogonal polyno-mials of function-valued Padé-type approximation is introduced.On the basis of the error formula,the least-squares function-valued Padé-type approximation is constructed.Their existence and uniqueness are studied.A recursive computation formula of the least-squares function-valued Padé-type approximation is given.In the end,an example is given to show that the method is effiective and stable.
