Some terms related to automatic swith-such liquid level switch and temperature switch came to me recently. These are quite new for me, a graduate in Materials discipline. I think these are some kinds of elements of mechanical engineering. The general defination and description of those terms are listed below when corresponding search through the Internet has been done.
Liquid level switch is mainly used in equipments which request liquid level is regularly kept unchangeably.Liquid level switch can be widely used in automobile, industry equipments, agriculture equipments and household electrical appliances.
As to temperature switch, it is responsive to temperature changes. Temperature switches generally are provided with a temperature responsive element which will open or close a switch when a predetermined minimum pressure or temperature is sensed by the responsive element.

As the saying goes, every coin has two sides. So does this one- GPS tracking technology. It is hardly to deny that high tech is a double-edged sword.
The reasons are quite obvious. For one thing, this high tech can guarantee the betterment of social security-policemen have possessed an effective and powerful weapon in avoiding of drug deal or some activities illegal. For another, people are forced to confront with this embarrassing situation—privacy being infringed and lost
Let’s move a little deeper and be more specific. What about tracking the Cops themselves? Even if I am not a cop, I can tell a cop being tracked felt like exactly a criminal being tracked. The results are same: if you want to track your employee by GPS tracking, you must undertake the consequences of the decline of the focus and efficiency. If you want to track your spouse or your kids by GPS tracking, sorry, get out! Your freak…
People always think of technology as a solution to problems, not a creator. But now they must change their mind before it is too late.
Finally, I have a question: would you like to track yourself by GPS tracking technology to show your wife or kids or your employer where you are?

今天又用google earth游览了一下德国慕尼黑以南starnberg lake的湖边风景,发现那里的小镇真的是很惬意。茂密的树林,青翠的草地,透明的河水,笔直的道路,还有那美妙的小桥,使得这些小镇既有乡间美妙的风景又有便利的现代交通。下面是我极喜欢的一处农舍:
想想吧,在晴朗的下午,坐在清澈河边的草地上,和朋友谈天,面包、啤酒自然不能少,微风徐徐吹来,那是多么的惬意。当然还可以在河上慢慢地划船,顺流而下,感觉一下河水和嫩草的清新味道。

如果你有兴趣,可以点击这里下载google earth的KMZ地标。相信你会发现更多迷人的地方。

德国小镇 杂记
记得去年发烧住院九天,5月19号出的院。这次,事隔一年零三天后,又发烧了。
昨天一大早踢了场比赛,不但没赢反而把左边小腿外侧擦破了巴掌大的面积。表皮创伤是最难受的,本身不出血,但是包含了大量的神经,比深度创伤更加疼痛。又加上夏天高温,渗出液还要急时处理,避免发炎。今天用酒精处理了一下,疼之甚以致我感觉不到疼了,而是痒,与高中时期左手手掌摔破那次相似。这种感觉错乱比疼痛本身更可怕。
晚饭在食堂吃的,夜里9点多突然肚子疼,然后就浑身乏力,结果今天就37度以上。我甚至搞不清原因何在–只能归结为身体疲劳、左腿发炎、食物不卫生、夜里着凉综合所致,至于哪个因素占主导地位尚不可知,也有可能是链状的因果关系,只存在诱因而根本就没有主导因素。
记得去年到校医院,医生上来就让我验血。直接对胳膊抽我不怕,最怕的就是扎手指头,也不知道是谁他妈发明的。小时候都扎耳朵,一个细长的钢针(我猜测为钢制)对着娇嫩的、柔软的、最重要的是充满鲜血的耳垂一刺,一小滴血就出来了,医生还嫌不够,就挤呀挤呀,直到用再大的力也挤不出来为止,送你一个又热又红的耳朵作为刺痛你的回报。高中的时候第一次体验到十指连心的感觉,那个医生右手持一类似钢笔尖的利器,左手捏紧我的一手指,猛然向下用力,当时的我也顺着蹲了下去,太疼了!!!谁告诉我的不疼!!!都是恶意的谎言,告诉我疼还能有个心理准备。去年采用了同样的方式从我手指上采集了几毫升血液,不过这次我没蹲,因为我在坐着,但是我喊了一声。医生貌似鄙夷地说,还是个男生。好像她坚持喊疼是女人的专利一样,看看,就这,还追求男女平等,她自己都把自己当成弱者。师兄说他闻到医院的气味就害怕,我倒不至于,因为小时候老妈上夜班的时候经常把我带到科室里,让我睡在几把椅子上,所以闻到医院走廊的气味还有熟悉之感,最怕的就是扎手指头、照屁股打针、做皮试,而不怕输水(普通话叫输液或者打点滴)。记得一次我就是不愿意做皮试,说做也可以,得让我爸先做一个,证明不疼,结果我爸做完了我还是不愿意做,气不打一处来的老爸把我按在椅子上让我妈强行给我搞了一针。看来有时候暴力是解决问题的最便捷途径。类似的事情还有小时院里的小朋友每几个月要打一次疫苗,很多小朋友害怕,我就一一给他们讲道理,说不疼,不打后果可能很严重之类的话,结果所以小朋友都打完了,我却吓跑了,还是几个人把我固定住问题才得以解决。
最后做一个总结性发言,希望明天体温正常。
