小松鼠历险记

一天,小松鼠正在睡午觉,熊叔叔来通知它晚上去参加森林晚会,它髙兴地答应了。晚上,小松鼠打扮好自己,一打开门,就看见蟒蛇先生在外面。蟒蛇先生温柔地说:“小松鼠,我们一起去森林晚会吧!”小松鼠想都没想,就一口答应了。     

Distribution Regularity of Muzzle Shock-Wave Inside Protective Cover

The injury of gunners caused by muzzle shock-wave has always been a great problem when firing inside the protective cover. The distribution regularity and personnel injury from the muzzle blast-wave were investigated by both test and numerical simulation. Through the inside firing test, the changes of overpressure and noise have been measured at different measuring points in the thin-wall cover structure with different open widths and shallow covering thickness. The distribution regularity of muzzle shock-wave with different firing port widths is calculated by ANSYS/LSDYNA software. The overpressure distribution curves of muzzle shock-wave inside the structure can be obtained by comparing the test results with the numerical results. Then, the influence of open width and shallow covering thickness is proposed to give a reference to the protective design under the condition of the inside firing with the same cannon caliber.

２１世纪是一个讲求实效、讲求变革的时代,也是一个崇尚教育、学习变革的世纪。它要求我们工作不仅要扎扎实实,还要灵活机动,以创新的精神解决和处理问题。种种信息表明,近年来,沈阳飞机工业(集团)有限公司(以下简称沈飞公司)在大力实施“技术、管理及制度”的三项创新战略中,以抓     

教育改变人命运

我在依阿华州苏城出生和长大，一出生就深度耳聋。我感到非常幸运的是我有极好的父母，他们也是聋人，但非常重视对我的教育。他们送我到密苏里州一所私立聋校上学，在那里我接受了优秀的基础教育，为我到苏城的公立普通中学上高中奠定了良好的基础。后来，我进入苏城Morningside大学读了2年，又到圣一路易斯城的华盛顿大学学习电子工程学，并获得科学学士学位。     

秋之韵

秋姑娘穿一身五彩袍,摇一手五彩铃,踏一辆五彩车,飘一袭草绿纱,放一路欢声笑语,来了!秋姑娘先抛出彩铃,化出粉、绿、红、橙、黄,分别点缀了月季、柏树、枫树、水杉和银杏树.它们看着自己的彩装,满意地点点头……     

A generalization of Kempe’s linkages

A new, general type of planar linkages is presented, which extends the classical linkages developed by Kempe consisting of two single-looped kinematic chains of linkages, interconnected by revolute hinges. Together with a locking device, these new linkages have only one degree of freedom (DOF), which makes them ideal for serving as deployable structures for different purposes. Here, we start with a fresh matrix method of analysis for double-loop planar linkages, using 2D transformation matrices and a new symbolic notation. Further inspection for one case of Kempe’s linkages is provided. Basing on the inspection, by means of some novel algebraic and geometric techniques, one particularly fascinating solution was found. Physical models were built to show that the derivation in this paper is valid and the new mechanisms are correct.     

在城雕研学中培养学生的美术学科素养

2014年,国务院印发《关于促进旅游业改革发展的若干意见》,将研学旅行纳入中小学德育、美育、体育等范畴。城雕研学通过文化考察模式、生活体验模式等进行展开。本文综述了在城雕研学过程中通过不同模式的研学逐渐培养学生图像识读、美术表现、审美态度、创新能力、文化理解的能力。     

自己装坦克

坦克——男生们的最爱!国庆阅兵仪式上,一辆辆全副武装的坦克徐徐开过,彰显国之强盛。看到这里,很多小朋友是不是都想成为名驾驶坦克的小战士呢?想要成为驾驶坦克的小战士,就得对坦克有一个全面的认识。那今天,就让小峰老师带着大家一起,走进创客课堂,揭秘坦克的“小秘密”,一起来制作坦克吧!不过,我们今天要做的只是坦克的下半部分,包括电机、轮子和履带。     

黄帝的传说

黄帝时代发生过多次战争,其中与蚩尤的涿鹿之战尤为著名,是结束各部落纷争的重要篇章。相传,战争十分激烈,那么加入蚩尤战队的都是谁呢?蚩尤的兄弟们:各个勇猛无比、铜头铁额;苗民:被发动外加逼迫就范;山精水怪:诸如魑魅魍魉之类,因怨恨黄帝手下的神荼、郁垒管制太严,前来投奔。
