简介：现代科学自从其诞生之日起就是一把双刃剑，它推动了人类文明不断进步，却也给人类与自然造成了负面影响。所以，我们在享受科技带给我们生活便利的同时也应不忘反省：科技的进步毕竟只能解决目前存在的问题，在这个过程中它也为人类埋下了反噬自己的种子。无论如何，科技确实给我们的生活带来了巨大的改变，但是我们应如何合理利用科技造福人类，并将其对人类与自然造成的负面影响降到最低，这是值得每个人深思的问题。

简介：为打印应用程序的工业大3D的一个新奇7轴机器人在这份报纸被介绍，它被机器人学和自动信息系统的研究所开发，Nankai大学。原型上的底，三维的打印上的机制深深地被把。由在打印的3D调查颜色失真的原因，一个新奇multistep赔偿算法基于模型优化和图象赔偿被开发。最后，试验性的结果显示出打印机器人站台和建议算法的3D的表演。

简介：打印的3D变得流行并且广泛地在最近的年里在各种各样的应用被使用了。越来越多的家用户有动机设计他们的自己的模型然后用3D打印机制作他们。然而，打印目标可以有结构的一些或因为用户可以是3D模型上的压力分析上的知识的缺乏，强调缺点。在这份报纸，我们在场帮助用户分析的一条途径一模型结构的力量当设计它的形状时。我们采用部分结构的分析而不是常规女性(有限元素方法)计算地昂贵的分析。基于部分结构的分析，我们在集成网孔设计帮助的途径进口骨骼，力量计算和网孔修正很好。骨骼能也指导节为分析造和负担计算。为有在在从分析结果的模型的阀值价值上的高应力的弱区域，我们的系统由放大骨骼的相应骨头以便使这些区域足够生硬改正他们。很多个实验表明了我们的途径的适用性和有实行可能。

简介：最近听了一节公开课，内容为高中《历史·必修3》中的“古代中国的发明和发现”。讲到我国古代四大发明时，执教老师运用多媒体教学，非常直观、形象。特别是讲到11世纪中叶，北宋平民毕升发明了胶泥活字印刷术，“它既经济，又便捷，是印刷术的一大革新，这种新技术，

简介：2009年，中国印刷业在比去年增加投入的前提下，利润并未实现增长，但二季度的印刷企业生产销售额比一季度呈现明显的回升趋势，显示了印刷行业已开始朝着良性方向发展。然而，环顾国际经济形势和外部环境，印刷业转暖形势不容乐观。如何在挑战中寻找发展机遇，将是印刷业面临的主要问题。

简介：600年前后的隋朝人从刻印章中得到启发，在人类历史上最早发明了雕版印刷术。雕版印刷是在一定厚度的平滑的木板上，粘贴上抄写下整的书稿，薄而近乎透明的稿纸正而和木板相贴。

简介：说起印刷，大家首先想到的肯定是四大发明，但要具体说说印刷是怎么回事，可能很多同学就答不上来了。

简介：印刷术是我国四大发明之一，印刷术对于文化促进作用是多方面的。印刷术由仿刻唐楷创造了书法优美的宋体（宋版字体）。版刻专业化、规模化生产，在文字规范的引导下，产生了匠体，一种机械整齐的字体，虽然出于刊刻的技术要求，却产生出版刻带来的别样审美意趣。明清以来好尚不同，俊秀雅致的长宋，威严稳重的扁宋，与手写软体各呈风采。仿宋体是匠体与软体结合的新体，方头体有篆刻背景，使得汉代铭刻体获得新生。印刷版刻字体是汉字形体史上不可或缺的重要篇章。
