Abstract:This paper discusses the close relation of geometry and architectural aesthetics in the aspects of ratio scale, geometric curved lines, geometric curved surfaces, etc.

几何与建筑美存在着密切关系,从比例分割、几何曲线、曲面等方面探寻了几何与建筑美的奇妙关系。

And the most important problem of the line form is curved line.

作为造型艺术，绘画中的形，尤其是线形的问题一直倍受关注；而线形中的曲线问题尤为引人注目。

OR curve is polynomial and rational parametric plane curve whose offsets are rational.

由于OR曲线可通过恰当的参数变换产生有理形式的等距线,因此根据给定B啨zier曲线离散端点条件,可构造特定连续阶的OR样条曲线来逼近该Bézier曲线,而将OR样条曲线的精确等距线作为B啨zier曲线的逼近等距线。

This paper describes the theory origin of the IS curve and Phillips curve under the frame of New Keynesian Economics and the two monetary policy rules in detail.

本文详细介绍了新凯恩斯经济学下IS曲线和Phillips曲线的理论渊源和两种主要货币政策规则的思想,并针对我国的经济数据进行实证检验。
