实验,过场?

By xrspook @ 21:15:49 归类于: 烂日记

一天都做实验真的很要命,不是说动手这事情很难,但33人挤在一个实验室用着那些又烂又残的仪器,然后做实验的时候声音可以说是震耳欲聋,我是其中一个“大声婆”,因为我真的无法忍受同学某些完全因为没有看书或者没有听讲而犯下的不可原谅的错误。于是就控制不了自己的音量……

我从开始就想把实验做好。无论是食品微生物的还是食品化学的,在做实验之前我真的有很认真的看过书,不懂不清楚的地方真的有去查过相关资料,但事实告诉我那还远远不够。因为有太多太多的未知因素了,除了我的水平太低,没有预料到我可能犯的错误以外还有很多很多仪器的缺陷。仪器不精确,我们根本就不能做出正确的答案,更何况要做出让我满意的答案?!无论我看书多么仔细,我总是做不到我预想的效果……

真的觉得我的食品化学综合实验的老师——沈**不是一个称职的老师。不单理论课上说废话,还要在实验课的时候玩失踪。看看他的资料;

沈**

1977年5月生,博士,讲师。2000年起先后就读于中山大学化学与化学工程学院物理化学专业和有机化学专业,2005年获得博士学位,于同年分配至华南农业大学食品学院工作至今。主要研究的领域为食品安全、生物有机和药物化学,攻读硕、博士期间主要从事流体分子动力学、超临界流体技术及其应用、天然产物有价成分的分离提取、基于天然产物的有机小分子药物的合成及生物活性研究等研究工作。主要承担或参与《食品与发酵工业分析》、《食品分析与食品化学综合试验》、《食品仪器分析》、《食品理化检验及感官评定》等课程的讲授工作。参加国际合作项目,国家自然科学基金等多项,已在《Tetrahedron》、《European Journal of Medicinal Chemistry》、《Tetrahedron Letters》、《Chinese Chemical Letters》等刊物上发表论文多篇,其中6篇论文被SCI收录。

好像很厉害的样子,但事实远没有文章里的那么好。也许他是那总会学不会教的人吧。每次实验就派2个研究生师兄,然后自己从开始到最后都不知道跑到哪里去了。我们成不成功根本仿佛和他无关。我们遇到的困难他根本不会在乎,因为他根本就不在场,不知道!而师兄的质量则是因人而异,今天连写在黑板的实验流程也看得我们十分辛苦,因为字实在太丑了!怎么这就是研究生!这就是我们的核心课!什么专业?简直就是过场!!!!

为什么现在的大学生素质如此低下,问问基层的老师吧,问问学生自己是如何做实验的!

我仍记得妈告诉我的一句话:“无论别人做实验如何随便,你自己也不能对自己随便。”没有规矩,没有严格,没有条规根本就做不好科学。我们需要的不是松散,我们需要的不是过场。我是有心学的,但我无能为力。不知道还有多少像我这样的大学生,多少兴致就是这样被抹杀。反正,这就是现代教育,这就是普及教育,这就是扩招,这就是社会的大趋势……

不知道还有多少次过场,什么时候才是我们有板有眼做主角?

A Whole Day in Experiment

By xrspook @ 21:38:57 归类于: 烂日记

A whole day (about 12 hours) in laboratory! I am almost crazy now! I really had a good beginning; however I couldn’t keep the luck to the end. Maybe the gray weather and the little cold air affected me. I don’t know what happened, I have repeated this log for three time, just because some little impossible mistakes.

This morning, we did our food microbiology experiment first. That’s funny, and perhaps I used all my luck at that time. Our class was divided into 8 teams, and I am in team 6. Our teacher separated 3 missions to us, and my team did the easiest one. We just needed to scale the powder of culture medium which is called Gause’s Synthetic Agar, and then dissolved it completely in boiling water, at last moved the liquid into flask and encapsulated it, that’s all! Compared with others, we were the most effortless! They should scale a lot of material and then cooked them for a long time. I never expected I would have such a pressure beginning in food microbiology experiment.

After that, we went to search some information about our papers of food in floor three. That’s the most unfortunately time today, my flash disk was infected by computer virus! I had never had such experience before! Just now, my Kaspersky Anti-Virus had killed it. It’s a Trojan virus. The phenomenon of infected this virus is that there will be a .txt files in your flash disk, however, you can’t open it, and when you deleted it, it will appear again, and in others names! Those names are all some sensitive words. And I even wanted to format the disk to remove the entire virus, but it didn’t work! Just Anti-Virus software can solve such problem.

The food chemistry experiment in afternoon was terrible. Most of the time, we were waiting, I waited our life in that classroom, I don’t’ think that can be a good feeling.

I should stop now; I should have a good rest, and then face my two experiment reports!
