1 change the CR = 10, fail to fire the engine
2 change the CR=8, make the engine work at 1500rpm, intake air temperature =38.4
fire the engine at

生活很充实,研究生的日子挺不习惯的,主要是因为自由太多了,自己安排时间,自己掌握课题的进度,最不可思议的是,竟然怎么研究怎么花钱也是我说了算.国外对科研的投入真的是不惜成本,前几天想申请一个设备竟然要5万人民币,学校也答应了,最后倒是我觉得很舍不得,先把这事放下以后再说.语言可结束了,说英文的机会突然间变少了,感觉自己的英语水平也下降了很多,没办法,每天都对着一台机器.我自己有了一个办公室,有了一个自己的实验台,我把自己的生活划分了很多的表格,比如每周的计划,实验前的准备,实验后的分析和结论,给导师的汇报,每个月要参加的课外活动.每天就是拿着不同的表格到处跑,然后做完一件事划一个勾.过春节,没啥感觉,大年三十和家里视频,所有家人都在一起问这问那的.其实过年就是过一个气氛,在异国他乡没有年节的气氛,也就没有过年的感觉.和家里视频完就去实验室作实验了,因为年三十的前一周被导师说进度太慢,所以整个春节都在加班.倒是初五在网上看到春节晚会有一点想家,尤其是说道:祝海外的华人春节快乐.呵呵,啥时候被分到这一类去了.一年一年变化真大,去年过年的时候怎么能想到一年后的样子.

Research Note 12-Feb-2008
read the propesal agian, 俗話說溫故而知新. Espaciaaly something written in english.
and think about what should do for my study.
1 DME injecter design
2 DME spray time control design
at night study UG, see the vidio and learn how to 拔模,如何改變曲面.

Research Note 4-Feb-2008
PLACE:Engine lab AIM:start the engine
Do:
1 start the coolant water circulation system and coolant heating system. wait until the pump make noise like "peng!peng!"
2 oil temperature is 60度; coolant water temperature is 80 (set up,90度 reality)
3 borrow oscilloscope and connect with the spark system and fuel duration controler
4 turn on the computer
Problem:
1 the oscilloscope is not showing the real time 喷油时刻,喷油持续期,点火时刻
2 no ignition of engine, only the monitor rotating
3 the wrong pump and fuel is out
4 can't measure and control the 喷油时刻,喷油持续期
5 no reaction on pc
Analysis:
1 示波器连线有误,
2 喷油过浓或者过稀,以至于造成熄火或者失火miss fire
3 点火时刻不对
4 火花塞处有积碳

luckywind 20:13:45今天网络不好,一直没登上线luckywind 20:23:32我在Brunel,读机械工程,3年,是硕博一起的。英国的学位大多数是一年或一年半,学费很贵,但是有的学完毕业可以给提供一年的工作机会,开销基本能赚回来。英国大学除了牛津剑桥,剩下的能在国内听过的大学实力都差不多,还是看专业看导师看研究方向。luckywind 20:30:03我是自己申请的,因为认识了导师,学校这边还有一个朋友,所以申请学校这一块没问题,后来签证也是自己准备的材料,自己递的签证。我从申请到走一共3个月,在燕大是学雅思去了。先拿到了conditional offer 就是有条件录取通知书,上面写清楚了条件(我的条件是雅思6.0或通过学校的语言课和语言考试),我雅思考了5.5,没有过,就申请了学校的一个3个月的语言课(因为我只差0.5分,所以11周语言就行;如果差1分就要读8个月的语言)。12月份语言考试,我通过了拿到了unconditional offer就是无条件录取通知书,一月分开始正式注册研究生。
luckywind 20:31:57因为我申请的是研究性研究生,所以可以在任何时候注册。但是一般硕士都要到9月开学(有的是一月)。所以我觉得,查问清楚,算好时间最重要。
luckywind 20:38:40我建议你现在先准备雅思,时间还来的及,先看看自己能打多少分,然后3个月可以提高0.5分,在5月底或6月初拿到雅思成绩,然后暑假就来英国读暑期的语言(就算考过了,我认为也要读一下语言,收益很大,而且会让正式学习的时候不那么吃力)。luckywind 20:40:31还有什么需要帮忙的就留言给我
