论武术套路演练中的动静节奏

以艺术学、哲学、美学等为理论参考,对中国武术套路演练中的动静节奏进行深入研究,认为在武术套路演练中动作要突现神韵,静要蕴含意境。同时,依据武术套路演练中动静节奏的上述审美特征,指出了动静节奏的艺蕴内涵应凸现出动迅静定,动韵静势,顿合规律等具体要求,进而推断出要从动态性、延续性、整体性、综合性的角度去把握武术套路演练中节奏的变化,为广大教练员和运动员提高武术套路演练的技巧以及其他从事武术科研的学者提供理论参考。     

对中国花样游泳双人自选中连接技术的分析

本文以第10届世界游泳锦标赛花样游泳比赛中各国的双人自选连接技术为研究对象，将中国花样游泳队运动员的连接技术，与国外高水平运动员的连接技术进行分析比较，找出了我国运动员的主要问题所在，并提出训练方法上的改进意见作为参考。为了更好地对花样游泳的连接技术进行分析讨论，本文还对连接技术的概念和种类进行了明确的定义和划分。

构建高职思政课“动态”考核模式

如何准确客观地反映高职院校大学生思想道德实际,即如何科学考核思想政治理论课始终是困扰高职思政教师的一大难题。本文结合高职教育教学实际和思政课教学特点,试图探索一条适合高职思政课的"动态"考核模式。     

Three-dimensional transient numerical simulation for gas exchange process in a four-stroke motorcycle engine

INTRODUCTION In-cylinder flow characteristics during fuel in-jection and subsequent interactions with fuel sprays and combustion are important effect on engine per-formance and exhaust emissions of an engine(Floch et al.,1998;Kim et al.,1999).Four key parameters control the flow field in an engine:the mean flow components,the stability of the mean flow,the tem-poral turbulence evolution during the intake and compression strokes,and the mean velocity near the spark gap at the time of ignit…

Cyclic behavior test of a new double-arch steel gate

A new double-arch structure for the gate used as tidal barrage and sluice was adopted in Caoe River Dam in China. It was a spatial structure made up of the right arch, the invert arch, the chord, etc., and was designed to bear bilateral loads. To research the cyclic behavior of the new double-arch structure, a scale-model cyclic test was conducted. First, the test setup and test method were presented in detail, and according to the test results, the cyclic behavior and failure characteristics of this structure were discussed. Then by analyzing the test cyclic envelope curve, it was found the curve was divided into three stages: the elastic stage, the local plastic stage and the failure stage at the local yield point and structural yield point. The gate model has local yield strength and structural yield strength, with both their values being bigger than that of the designing load. Therefore, the gate is safe enough for the projects. At last, dynamic property of the gate was analyzed considering additional mass of the water. It was found that the tidal bore shock would not cause resonance vibration of the gate.     

A new digital approach to design multivariable robust optimal control systems

This paper presents a new design of robust optimal controller for multivariable system. The row characteristic functions of a linear multivariable system and dynamic decoupling of its equivalent system, were applied to change the transfer function matrix of a closed-loop system into a normal function matrix, so that robust H∞optimal stability is guaranteed. Furthermore, for the decoupled equivalent control system the l∞optimization approach is used to have the closed-loop system embody optimal time domain indexes. A successful application on a heater control system verified the excellence of the new control scheme.     

试论FinalRender中HDRI的应用

为实现具有像片真实感光线分布的渲染。全局照明和光能传递两种技术得到了应用。今天，全局照明逐渐成为唯一合理的选择。标准的全局照明算法和高动态范围图像技术结合应用于渲染，于是我们得以创建高品质的图像。本使用了渲染器FinalRenderstage V1．0for 3ds max4来示范渲染问题。
