发帖数: 38 | 8 对文科生普及一下这些名词，呵呵。
一般职称加了Engineer的，都要求比较高的学历背景。
比如：你说的电焊工是Welder，一般只需要高中学历加上一些培训和焊接执照就可以做
电焊操作工了。而如果是Welding Engineer，一般都得至少本科以上，因为要知道焊接
原理，焊后的材料变化，缺陷，焊接后处理等。Welding Engineer本身可能一辈子都没
怎么拿过焊枪，也不妨碍他们“纸上谈兵”。
同样的还有比如：
Material manager(听着是manager，其实是管材料库存的) VS. Material Engineer （
材料工程师）；
Mechanic (修车工） VS. Mechanical Engineer (机械工程师）；

我摩托车header边上的整流罩断了一块，之前用沃尔玛买的普通牌子树脂粘，可能因为
靠近header温
度很高，一开始还好，过几天树脂就自行断裂了。网上google一下高温树脂，发现还是
JB weld牛
逼，600度F的rating，别家牌子的基本300F。而且强度也高，4000psi了，别家大多
3000psi以
下。
唯一的缺点是，凝固时间巨长，3-4个小时过去还是一坨软塌塌的，但过了一天就好了。
如果要凝固快，可以买J-B KWIK，但这个无论强度还是温度耐受力都不如原版的。
昨天还帮LD粘了一下窗帘的轨道，LD很满意。

http://www.sina.com.cn 2011年06月27日 00:37 《新世纪》周刊
财新《新世纪(19.12,0.00,0.00%)》记者 严江宁
中钢能否独自承担起投资在350亿元以上的铁路和港口建设大任？对于目前负债率
高企的中钢来说，这是一个不可能的任务
一个耗资13.6亿澳元(约合93亿元人民币)“敌意收购”的澳大利亚铁矿项目，却因
为港口、铁路等基础设施问题，在收购三年后叫停。2011年6月23日，中国中钢集团公
司(下称中钢)宣布，暂停在西澳洲的Weld Range铁矿项目，停止与之相关的所有工作，
并对在建项目收尾。此外，中钢也将终止Koolanooka和Blue Hills项目以外的所有勘探
工作，关闭在杰拉尔顿的办事处。这些铁矿均为中钢2009年收购的澳大利亚铁矿石商中
西部公司(Midwest Corporation Limited)所有。
这桩收购当时曾被称之为“中国首起成功的海外敌意收购”，如今看来，却因为资
产价值大幅缩水而显得得不偿失。中钢最终是以每股6.38澳元的代价完成了对中西部公

李光耀与新加坡的陨落
李光耀死在中国亚投行诞生的同一个月，生命的偶然透露出一丝历史轨迹。
如果把海洋进行简单隔离的话，南海贸易占世界贸易的 40%，台湾、日本海峡则占世界
贸易的 10%。
新加坡则处在南海贸易的地理枢纽位置，新加坡地处热带，长年受赤道低压带控制，为
赤道多雨气候，气温年温差和日温差小。平均温度在 23-34 度之间。
这让我想起沙特阿拉伯，沙特的石油，对石油美元体系霸主地位有决定性影响。这说明

链条的伴生物，而非相反。

地位海洋枢纽位置让位与欧亚大陆文明回归的时候，意味着新加坡这个君主国，登基的

中國中鋼集團公司多個海外項目遇險 總裁黃天文被免職
鉅亨網新聞中心 (來源：財訊.COM) 2011-06-29 09:05:32
中鋼海外投資屢屢受挫，中鋼集團公司總裁黃天文被免職，對於中鋼總裁的人事調整，
中鋼內部尚未公布是否追究其責任。
綜合媒體6月29日報導，國資委副主任金陽在中鋼集團內部宣布免去中鋼集團總裁黃天
文職務，由中鋼股份有限公司總經理賈寶軍接任（出任中鋼集團總經理、黨委副書記）
。 黃天文此前擔任中鋼集團總裁、黨委副書記，同時還擔任中鋼股份有限公司董事長
職務。對於黃天文免職后的去向，國資委宣布時稱“另有安排”。知情人士透露，黃天
文可能將被安排到其他央企任外部董事或獨立董事。
對中國中鋼集團公司(下稱“中鋼”)總裁黃天文被免職，盡管國務院國資委沒有說明緣

2.参加了很多国内老师的项目,参加了一些海外老师的暑期短期项目,有些学术锻炼和想

4.积极参加各种活动,精力充沛,勤奋,把自己的时间,安排的满满当当的,有废寝忘食的

5.非常有计划性和目的性,经过几年奋斗,作为本科学生,已经达到面面聚到的无短板程
