中国的传统染织纹样及其对日本染织纹样的影响

本文总结了中国与日本之间染织文化交流的历程和中国传统染织纹样的发展,分析了中国文化对日本染织纹样的影响,以及日本传统染织纹样异于中国的特点和日本风格的形成。作者认为:1.日本传统染织纹样在母题、形式、内涵和名称诸方面受到中国的影响极大;2.这种影响以唐代和宋元为甚,明代以后日本逐渐自成一家;3.被称为“和样意匠”的日本风染织纹样表现了日本独特的民族性和审美情趣,特别是日本人对色彩的特殊感觉和嗜好;4.主要是由于技术上的原因,日本在印染方面的成就高于织绣纹样方面的成就,中国则相反。

Cycle and circle tests of balance in gain graphs: Forbidden minors and their groups

We examine two criteria for balance of a gain graph, one based on binary cycles and one on circles. The graphs for which each criterion is valid depend on the set of allowed gain groups. The binary cycle test is invalid, except for forests, if any possible gain group has an element of odd order. Assuming all groups are allowed, or all abelian groups, or merely the cyclic group of order 3, we characterize, both constructively and by forbidden minors, the graphs for which the circle test is valid. It turns out that these three classes of groups have the same set of forbidden minors. The exact reason for the importance of the ternary cyclic group is not clear. © 2005 Wiley Periodicals, Inc.

THE QUALITATIVE CONTENT OF RENEWABLE RESOURCE MODELS

This paper analyzes the extent to which standard dynamic renewable resource models possess refutable implications. Both the steady state comparative static and local comparative dynamic properties of the standard model are studied. A unified framework is developed which enables one to analyze the qualitative properties of any standard renewable resource model. This is achieved by explicitly linking the local stability, steady state comparative static, and local comparative dynamic properties of the model.

An improved numerical simulator for multiphase flow in porous media

In basin modelling the thermodynamics of a multicomponent multiphase fluid flux are computationally too expensive when derived from an equation of state and the Gibbs equality constraints. In this article we present a novel implicit molar mass formulation technique using binary mixture thermodynamics. The two proposed solution methods, with and without cross derivative terms between components, are based on a preconditioned Newton‐GMRES scheme for each time‐step with analytical computation of the derivatives. These new algorithms reduce significantly the numerical effort for the computation of the molar masses, and we illustrate the behavior of these methods with numerical computations.

RECONSTRUCTION OF BINARY RELATIONS FROM THEIR RESTRICTIONS OF CARDINALITY 2, 3, 4 and (n - 1) II

We shall prove here that any binary relation on a base E with cardinality n > 6 is reconstructible from its restrictions of cardinality 2, 3, 4 and (n - 1). This proof needs results of part I of this paper where we characterize any pair of relations R, R' which are 2-, 3- and 4-hypomorphic. As a corollary we obtain that any binary relation is (n - 4)-reconstructible (when n > 9).     

时间词义赋值的个别差异的初步研究

运用模糊统计对１０个持续时间词进行了初步研究，然后选出其中２个，让不同个性特征的男女被试对其赋值。结果表明：在时间词的估计值和估值范围上，Ａ型行为类型者的赋值都小于Ｂ型行为类型者；低焦虑者的时间词的估值范围大于高焦虑者；在赋值特征上性别差异不显著．
