是有的, 有这回事

爱迪生是怎么想起用炭丝作灯丝的????急!

爱迪生将1600多种耐热发光材料逐一地试验下来,唯独白金丝性能量好,但白金价格贵得惊人,必须找到更合适的材料来代替。1879年,爱迪生最后决定用炭丝来作灯丝,竟能连续使用45个小时
为了研制电灯,爱迪生在实验室里常常一天工作十几个小时,有时连续几天试验,发明炭丝作灯丝后,他又接连试验了6000多种植物纤维,最后又选用竹丝,通过高温密闭炉烧焦,再加工,得到炭化竹丝,装到灯泡里,再次提高了灯泡的真空度,电灯竟可连续点亮1200个小时。电灯的发明,曾使煤气股票3天内猛跌百分之十二。
继爱迪生之后,1909年,美国柯进而奇发明了用钨丝代替炭丝,使电灯效率猛增。从此,电灯跃上新台阶,日光灯、碘钨灯等形形色色的灯如雨后春笋般登上照明舞台。

急~~~~!10月29号来的月经,然后上个月,11月30号跟老公ML。。

有时候安全期也有可能怀起哟,建设你过两天再查一次。虽然体外射精但有时你老公兴奋的时候也会有精子跑出来哟。时候月经晚来也是很正常的,所以不要太着急啦。

以《你听过的一首歌》为题,写作文。 急,现在就要。

我教你怎么写,以后作文不会别叫人给你写,这样子你考试也叫人给你写么?你应该现在就养成好好自己写作的习惯。
这篇作文,应该从你感悟最深的一首歌入手,谈谈你对这首歌的某1句的感悟乃至整首歌,然后联系到生活中去,社会中去。

我要找网络妈妈的观后感,谁有啊,急~急~急~急~急 谁有找我

网络妈妈观后感
在看完《网络妈妈》的回家途中,我想了很多。网络就像一把双刃剑,既能使人长时间沉湎其中无法自拔,伤害身心健康;又能仅轻松地点击几下,就可找到最新资讯和所需资料,而关键在于如何利用网络,是让网络支配我们,还是我们支配、利用网络?
许多人爱玩网络游戏。是的,适当地游戏一下可以放松心情,有的游戏还有利于开发智力,但是过分沉迷就会像影片中的嘉嘉:逃课上网,半夜三更去网吧,为的仅是玩游戏!父母为此心都要操碎了!我们应清醒地认识到,网络世界里一切都是虚拟的,在游戏里过五关斩六将,给人短暂的成就感,可游戏结束了,我们还能得到什么?反而是我们把时间、健康、金钱投资给网络,网络什么也没有回报给我们。我们正值花季,正值奋发学习的年龄,有很好的前途和未来,为什么要被网络奴隶?如果很好地利用网络,我们可以不出门便尽知天下事,各种所需资料在网络上应有尽有,好的学习网站还可以帮助提高学习成绩,电子邮件、视频聊天方便快捷,还可通过网络与世界各地的同龄人交朋友……网络其实有很多用途,不光是玩游戏。
互联网是时代发展的标志,是信息化时代必不可少的工具。人类发明了网络,可并非每个人都具备利用好它的本领。我们上网就应“兴利除弊”,充分利用网络,使其成为学习、生活中的好帮手,不要一味沉迷网络之中。毕竟,网络之外的现实世界更精彩!
随着新世纪的到来,科技进步脚步日益加快,网络也普及到每一个平常百姓家中,作为“九零后”的初中生,我们应该如何用好网络这把双刃剑,做一名新世纪的网络少年呢?
在《网络妈妈》这部影片中,几次出现警醒的报纸头条:“14岁少年通宵上网,昏迷卧轨而死!”“青年上网三天三夜,导致视网膜脱落!”“儿子竟为网络残害母亲”……片中的主角嘉嘉,更是迷于网络游戏,和身边所有的人作对。不好好学习反而将现实生活寄托在《传奇游戏》中,好在有“网络妈妈”的存在,才使嘉嘉重新找回了自我。
网络是很有用的,有谁不喜欢“网上冲浪”呢?但重要的是应该用怎样一种态度去对待它。对于游戏,要适可而止,不要过度沉迷。游戏只能放松自己,不能把自己的生活当作游戏人生。在网上,我们要拒绝那些不良的、对身心有害的信息,多点浏览一些有用的、对我们有帮助的信息。“网络妈妈”也亲口说道,网上有许多不错的学习网站,对我们的学习很有帮助。
作为一名新世纪的网络少年,我们应该正确对待网络,学会如何正确运用网络资源,而不能沉迷于网络游戏,染上网瘾
父母的爱,我们要报答,要珍惜他们为我们付出的汗水……

The Eight Plas
Mike Brown
On August 24th 2006 the word "pla" was given its first-ever scientific definition by a vote of the International Astronomical Union. With the raising of a few yellow cards in Prague Pluto was demoted from full-fledged pla to "dwarf pla." The object 2003 UB313, sometimes called Xena, sometimes called the "10th pla," which in many ways precipitated this final debate, bees the largest known dwarf pla. Unless astronomers revisit this issue at some point in the future, it is unlikely that there will ever be more than eight plas.
What was the problem with nine (or ten) plas?
Pluto and 2003 UB313 are significantly smaller than the other plas. If you were to start to classify things in the solar system from scratch, with no preconceived notions about which things belong in which categories, you would likely e to only one conclusion. The four giant plas -- Jupiter, Saturn, Uranus, Neptune -- belong in one category, the four terrestrial plas -- Mercury, Venus, Earth, Mars -- belong in one category, and everything else belongs in one or maybe more categories. You wouldn't lump the largest asteroid -- Ceres -- in with the plas, you would group it with the other asteroids. Likewise you wouldn't group the largest object in the vast swarm of objects beyond Neptune (the "Kuiper belt") with anything other than the Kuiper belt. The previous nine (or ten) "plas" enpassed the group of giant plas and the group of terrestrial plas and then awkwardly ventured out into the Kuiper belt to take in one or o of the largest of those objects. Using the word in this way makes no scientific sense whatsoever.
Two solutions to the problem of Pluto and 2003 UB313
Leave no iceball behind
Astronomers were faced with o options for a scientific definition of the word pla. One option was to say that what makes a pla a pla is simply the fact that it is large, round, and orbits a star. Ignore everything else that you know and concentrate on that. Why round? If you place a boulder in space it will just stay whatever irregular shape it is. If you add more boulders to it you can still have an irregular pile. But if you add enough boulders to the pile they will eventually pull themselves into a round shape. This transition from irregularly shaped to round objects is important in the solar system, and, in some ways, marks the transition from an object without and with interesting geological and plaary processes ouring (there are many many other transitions that are equally important, however, a fact that tends to be ignored in these discussions).
Of course, to truly talk only about the object in isolation and to ignore everything else you know you should also ignore the fact that the object is in orbit around another pla. It is hard to make a consistent argument that a 400-km iceball should count as a pla because it might have interesting geology, while a 5000-km satellite with a massive atmosphere, methane lakes, and dramatic storms (Titan) shouldn't be put into the same category, whatever you call it. For most people, considering round satellites (including our Moon) "plas" violates the idea of what a pla is.
The other difficulty with this definition is that it instantly makes 50 plas in the solar system with the likelihood of hundreds ing soon. Such a huge change in the number of plas is a big hint that this definition is a huge change in what we monly think the word "pla" means. While most astronomers would agree that round vs. non-round is an important distinction in the solar system, most appear to feel that forcing the word "pla" to be the word that describes this transition is incorrect. This radical re-definition was initially proposed by the IAU but was met by heated opposition and had to be dropped.
Consider the circumstances
The other scientific definition that makes sense is to acknowledge that by any classification scheme that considers circumstances -- where the object is, what else is in orbit near by, whether an object is a satellite -- the first eight plas are clearly in a class of their own. There are many ways to attempt to state this definition: a pla is by far the dominant mass in its region of space, a pla has cleared its neighborhood of all other significant masses, a pla is the aumulation of most of the material in its orbital vicinity. While none of these definitions can be stated with rigorous precision, they are precise enough for the case of the Solar System where the division beeen objects with have and have not mostly cleared their regions of space is enormous.
One of the best ways to view this definition is to consider some of the distinct regions of space. The asteroid belt, for example, is a collection of small rocky bodies beeen Mars and Jupiter with many millions of members. The largest asteroid Ceres is not nearly massive enough to have aumulated all of the other asteroids, nor is it massive enough to shove the asteroids out of the solar system. It is not a dominant mass within the asteroid belt. The exact same could be said of Pluto and 2003 UB313 (which are essentially the same size and both in the Kuiper belt along with millions of other bodies). Every one of the eight plas easily passes this test though. The eight plas were created from an aumulation of most of the material that remained in their vicinity. They are the dominant bodies in their regions of space.
