焊接专业教学改革思考

为了使焊接专业人才更好的适应经济发展和社会需求,焊接专业教学必须注意授课方式的改革,加强实践训练突出创新能力和创新意识的培养,同时应与教学计划同国际焊接工程师培训课程结合起来。     

批评与启蒙——鲁迅是如何看待国民性的

鲁迅不仅对＂国民性＂进行了理性的揭露和批判,而且还采用了文学的手法,通过典型的艺术形象的塑造,把＂国民性＂形象具体地展示于世人面前,并给予有力地批判,鲁迅从各个方面暴露了＂国民之陋劣＂,目的只有一个是为了改革国民性,只有勇于改革积极＂改打这病根＂,这个民族才有希望,才能实现民族的伟大振兴。

Influence of Temperature on Creep Behavior of Ag Particle Enhancement SnCu Based Composite Solder

The creep properties of solder alloys are an important factor affecting the reliability of soldered joints in surface mount technologies. Particle-enhancement is one way to improve the properties of solder alloys. The temperature of the solder joint is one of the primary factors affecting the solder joint creep prop-erties. Single shear lap creep specimens with a 1 mm2 cross-sectional area were fabricated using Ag parti-cle enhancement 99.3Sn0.7Cu based composite solder and 99.3Sn0.7Cu eutectic solder to examine the in-fluence of temperature on the creep behavior of solder joints. The results show that the solder joint creep resistance of the composite solder joint was generally superior to that of the 99.3Sn0.7Cu solder joint. The creep rupture life of the composite solder joint was reduced by increasing temperatures at a faster rate than that of the 99.3Sn0.7Cu eutectic solder joint.     

用健康的人格培养健全的人——浅谈职教语文教学中人格的培养

我国的国情决定职业教育担负着培养高素质劳动者的艰巨任务。但是职高学生的现状与职业技术教育的培养目标并不相符,绝大多数学生重工轻文,为学习而学习,为就业而学习,造成了职高学生综合素质不高,继续学习能力较低的状况。为了改变这一状况,作为语文教师,应充分利用语文的工具性和人文性,提高职高学生的思想境界和驾驭语文的能力,使其成为高素质的劳动者。
