单腿人生的精彩

It was a hot summer's day and the air was filled with the 1)scent of freshly cut grass.As the 2)blue jays 3)fluttered their wings through the light breeze,I could hear them 4)chirping a melody.I was playing in my 5)backyard with some kids.     

海知道,我知道

在圣托里尼岛与一位摄影师结为好友。聊天中，他说他偶尔也会为一些新婚夫妻在伊亚拍摄婚纱照，拍摄过程中他发现一个很有趣的现象。“每个人都想要拍蓝天、大海、教堂的十字尖顶，以及号称世界上最美的日落。我对他们说，再走下去一点，会有很漂亮的巷子和小花，却很少有人愿意去拍。”     

高校“立德树人”的实现路径探析——学习贯彻习近平总书记关于促进青少年学生全面健康成长的重要论述

"立德树人"是党中央把握教育规律,掌握教育发展趋势,为实现科教兴国和人才强国而做出的重要决策。高校要提高教育质量必须把"立德树人"作为根本,以"育人为本理念"为隐性路径、以"师风师德建设"为重要路径、以"社会齐抓共管"为基本路径,将培育社会主义核心价值观融入教育全过程。

Architecture Singularity Analysis of 4-U■S/U■U 5-DOF Parallel Mechanism

Architecture singularity of a parallel mechanism with five degrees of freedom (DOF) is analyzed. Such mechanism consists of a movable platform connected to the base by five active limbs. Four of them are identical 6-DOF limbs and the last one has the same DOF as the specified DOF of the movable platform. Based on the kinematics analysis, two categories of architecture singularities for such mechanism are proposed. Then the sufficient condition for each singularity is researched. Results show that the mechanism is singular when it employs each category of the proposed architecture, provided that it satisfies the corresponding sufficient condition. It can be concluded that the proposed two categories of architecture singularities should be avoided with the following dimensional synthesis of such mechanism.     

基于VC++的教学评价体系权重的实现研究

在教学质量评价系统中,评价权数是整个评价的核心问题,正确确定评价指标的权值,对评价结果影响巨大。本文在使用AHP(层次分析法)进行权值评价模型研究的基础上,使用VisualC++可视化编程语言,进行权重指标研究实现。进行实现过程流程设计、函数设计、矩阵运算,最后得出适合一般学校使用的权重指标值,同时也可以根据各评价学校的实际情况,重新进行权值评价计算,为科学评价教学效果提供依据。
