⑴ 博客兴起于什么时候

博客的历史
最早,是由Jorn Barger在1997年12月提出博客这个名称。但是在1998年,互联网上的博客网站却屈指可数。那时,Infosift的编辑Jesse J.Garrett想列举一个博客类似站点的名单,便在互联网上开始了艰难的搜索。
终于在1998年的12月,他的搜集好了部分网站的名单。他把这份名单发给了Cameron Barrett,Cameron觉得这份名单非常有用,就将它在Camworld网站上公布于众。其它的博客站点维护者发现此举后,也纷纷把自己的网址和网站名称、主要特色都发了过来,这个名单也就日渐丰富。到了1999年初,Jesse的“完全博客站点”名单所列的站点已达23个。
由于Cameron与Jesse共同维护的博客站点列表既有趣又易于阅读,吸引了很多人的眼球。在这种情况下,Peter Merholz宣称:“这个新鲜事物必将引起大多数人的注意。作为未来的一个常用词语,web-blog将不可避免地被简称为blog,而那些编写网络日志的人,也就顺理成章地成为blogger——博客”。这代表着博客被正式命名。
随着博客数量的增多,每个博客网站上编写的网络日志的内容也混杂起来,以至把每一个新出的站点主要内容和特色都不可能搞清楚。Cameron后来就只在网站上登载熟悉的博客站点了。时隔不久,Brigitte Eaton也搜集出了一个名叫“Eaton网络门户”的博客站点名单,并且提出应该以日期为基础组织内容。这也建立了blog分类排列的一大标准。
1999年7月,一个专门制作博客站点的“Pitas”免费工具软件发布了,这对于博客站点的快速搭建起着很关键的作用。随后,上百个同类工具也如雨后春笋般制作出来。这种工具对于加速建立博客站点的数量,是意义重大的。同年的8月份,Pyra发布了Blogger网站,Groksoup也投入运营,使用这些企业所提供的简单的基于互联网的工具,博客站点的数量终于出现了一种爆炸性增长。1999年末,软件研发商Dave Winer向大家推荐Edit This Page网站,Jeff A. Campbell发布了Velocinews网站。所有的这些服务都是免费的,他们的目的也很明确:让更多的人成为博客,来网上发表意见和见解。

⑵ 音叉的响度较大时,它的振幅较大,这是什么法

音叉(tuning fork)是呈“Y”形的钢质或铝合金发声器。
各种音叉可因其质量和叉臂长短、粗细不同而在振动时发出不同频率的纯音。音叉检查在鉴别耳聋性质——传音性聋或感音性聋方面,是一种简便可靠的常用诊查方法。
用音叉取“标准音”是钢琴调律过程中十分重要的环节之一。它的重要性在于关系到一台钢琴各键音处在什么音高位置上。
在教学中,音叉可以用来演示共振。
敲击音叉,采集声波波形图。试验发现:轻敲音叉,音叉振幅小,波形图的幅度小,这时音叉发出的声音也小;重敲音叉,音叉的振幅大,波形图的幅度大,这时音叉发出的声音也大。说明:响度跟音叉振动的振幅有关。振幅越大,响度越大;振幅越小,响度越小。
目前最常为音乐家使用的音叉,频率为440Hz。此音高长久以来就被作为乐团的调音标准,因为他同时为小提琴第二弦的音高以及中提琴第一弦及大提琴第一弦的高八度音高。不过市场上也有各种其他音高的音叉,如发出钢琴中央部基准组所有音高的音叉。
音叉在1711年由英国人约翰·朔尔(John Shore)发明。他是一位宫廷小号手,作曲家格奥尔格·弗里德里希·韩德尔及亨利·普赛尔皆曾在曲子中专门写下给他表演的段落。他还是一个鲁特琴手,鲁特琴非常难以调音,朔尔发明音叉来给鲁特琴调音。
音叉受到敲击后所发出的音符非常的微弱,常常只有拿到耳边才听得清楚。为此,有时在敲击后会将音叉压在如桌子等固体平面上,此举让这个平面有共振板的作用,大幅增加了音量。
音叉主要用于乐器调音,虽然电子调音器现已存在,而且一些音乐家拥有绝对音感。当音叉需要调音时,可以在两端分叉的部分做调整:磨短尖端的部分以频率调高或者修整两叉中间接合处以频率调低;或者调整两尖叉的重量。即便经过调音,音叉的频率仍会因为材料的弹性模数改变而受影响,为了使音叉发出准确的音高,仍应将其封存在温湿度控制良好的地方。大型的音叉通常由电力驱动,如同电铃,因此可不间断地震动。

⑶ “发明筷子的重要性”英语作文80字

A: In the 17th century, when a British businessman heard that there were 100 million people in China, he was determined to go there and sell spoons. He thought, even if a spoon would only sell for one penny, he would still make 100 million pennies, but he didn’t succeed. The Chinese people used chopsticks, not spoons.
B: Some people did some research on the origin of China’s chopsticks compared to the knife and fork in the West. One theory is that China was an agricultural society and relied on vegetables for food. Chopsticks were very convenient tools for eating. The Westerners, on the other hand, were nomads and lived on meat. The knife and fork were more practical. Others believe that China did not have much instry, and therefore people used chopsticks. The West was an instrial society, so their eating utensils were made of metal.
 
A: Sounds interesting! When I first learned that the Chinese use a pair of sticks to eat with, I was curious how they would drink soup. Just like the Indians who use their fingers to eat, do they also use their fingers to drink soup?
B: Whatever the reasons why the Chinese use chopsticks and Westerners use knife and fork, it is a result of their respective cultures. Chinese culture is developed around collectivism which stresses communion and harmony. Western culture emphasizes indivialism. In terms of eating customs, chopsticks and knives and forks are two desperate expressions of this cultural difference. The Chinese like to have communal meals where everybody eats out of the same bowl of food. Chopsticks were used in order to discourage people from eating more than others. This was not only a good way to preserve collectiveness, but also to limit indivialism. It is more straightforward in the West. People eat their meals on their own, and there is no restriction on how to eat.
 
A: That sounds quite reasonable.
B: In addition, table manners are very strict ring the Chinese meal. Respect has to be given to the elderly. Eac

⑸ 除了文化因素,中国人为什么用筷子而非刀叉

What’s the point to eating food withchopsticks instead of knives and forks, apart from the cultural aspect?

除了文化因素,还有什么原因促使中国人用筷子而不是刀叉?

Answer Wiki
Easier to cleanen masse.

方便把他们放一起清洗。(译注:筷子一次洗一大把)

You can make apair if you find yourself in a pinch.

情急之下你自己也可以捣鼓一双筷子出来。

As with spoons,grasping food does not modify food textures the way piercing food does.

和用勺子一样,夹起食物不会像叉食物一样破坏食物的纹理并给食物留下一个个小窟窿。

Chopsticksprovide less utensil-to-mouth contact, highlighting the pure flavors andtextures of the food. Steel utensil do not affect flavor, but other materialsmight.

筷子减少了食物先接触盛餐器皿再送到嘴巴里这个环节,最大程度地保留了食物本来的风味和质感。铁质器皿不会影响到风味,但其他材料的器皿可能会。

Increase ddevelopment of manual dexterity.

促进了人敏捷度和灵活性的开发。

One-handedeating allows freedom of usage for the other hand, just as if using a spoon.

只用一只手吃给另一只手的使用腾出了空间,比如说你另一只手在可以同一时刻用勺子。

Increasedefficiency when transferring foods from platter to plate, unless rice, peas orliquids are concerned, in which case a spoon is a clear winner.

在把食物从装盛的盘子里盛到餐碟子里时筷子具有更高的效率,如果不考虑盛米饭、豌豆或者舀汤汁时勺子更有优势的话。

Some diners mayeat slower, which may make food taste better and may cause them to eat less.And eating slower means better digestion

吃饭的速度会因为用筷子而变慢,从而让食物的滋味在舌尖能更好的绽放并且使人吃的更少。吃得更慢就可以消化得更好。.

Somefoods are easier to grasp with chopsticks (single long beans, noodles in soup,etc.)

一些食物更容易被筷子夹起来(长豆角,汤面等等)。

Increaseshygiene and decreases messiness when eating some "finger-foods."

Chopsticks havea non-obvious advantage over a fork and a knife. This advantage will becomemore widely appreciated with the growth of space tourism. Yep, that’s right. Inspace, chopsticks are more practical than a knife and a fork.

筷子比起刀叉有一些不明显的优点。这种优点被太空旅行事业的发展所看重。是的,没错。在太空中用筷子比用刀叉要更实用。

I predict thatchopsticks will be vastly more popular as the choice of utensil in space. Theyaren’t widely used in space yet because most of the human spaceflight to datewas done by nations who have a cultural preference for other utensils. As spacebecomes more accessible to people from other cultures, the usage of forks andknives in space will be relegated to a fun fact in history books.

我有预感,筷子会被更广泛地被采用为太空餐具。筷子迄今为止没有广泛地应用于太空中是由于航天事业是由各国各自开展的,不同国家的宇航员对餐具有着不同的偏好。当太空事业真正面向不同文化背景的人们开放时,刀叉的使用将成为有趣的历史往事。

What’simpractical about using a fork and a knife in space?

在太空中用刀叉有什么不方便呢?

First of all, tocut a piece of food in space with a fork and a knife, you need to stab it withthe fork then slice it with the knife. Both of these actions require you topress down on the piece of food you’re cutting. And that’s a problem rightthere, because Newton’s third law predicts that when you push something, thatsomething also pushes you back. Down here on the surface that isn’t a problem,because the piece of food is supported from below while Earth’s gravity isconstantly pulling you down. In micro-gravity (e.g. in a spacecraft in lowEarth orbit) however, where both you and the piece of food are in free fall,you’d very noticeably push yourself away from the table while stabbing the foodwith a fork, let alone cutting it with a knife. You’d have to hook your feetunder a railing and pull yourself towards the table using your legs, whichsounds rather annoying.

首先,为了在太空中用刀叉把食物切成很多块,你需要用叉戳着食物然后用刀切开。这两种动作的完成都需要把你切的那块食物给牢牢按住。这就是问题所在了,由于牛顿第三定律,你在推某样东西的时候要受到它的反作用被推回去。在地表这可不算个事儿,因为在你被重力往下拉的同时,食物也受到了下方的支持力。然而,在微重力的环境下(飞船在近地轨道上飞行时),你和你的饭菜都在做自由落体运动,你用叉子戳食物的时候很显然会被桌子一下推开,更别提用刀去切它了。这听起来很让人光火,因为你不得不用你的脚勾住护栏,然后用你的胳膊朝着面前的桌子把自己拽回去。

Long storyshort, cutting food in space isn’t easy. Likely for that very reason,non-liquid space food is already packaged as small bite-sized chunks that canbe eaten without cutting. That makes knives unnecessary. Forks are also rarelyused for stabbing, because the water-content of the food makes it simply stickto utensils, which means that a spoon works just as well. Also, chopsticks.

概括起来就是,太空中切食物非常困难。正是因为这个原因,非液体太空食物都会被做成一小块一小块的,这样就可以不用切直接吃了。这就没必要带刀了。叉子也很少被用来叉食物,食物中的水分会使食物残渣容易附着在餐具上,勺子和筷子也同理。

What’s practicalabout chopsticks in space?

那么筷子在太空中有什么实用的地方呢?

Most peopledescribe the experience of eating with chopsticks as “having really longfingers that you don’t mind getting sticky.” As it turns out, that’s exactlywhat you want in space. Anything you can eat with your fingers, you can eatwith chopsticks; they’re extremely versatile. In fact, they’re more versatilein space than down here! Don’t believe me? Watch astronaut Don Pettit drink teawith chopsticks:

有人这样形容用筷子吃饭的体验:就像是“拥有了一双不用担心因为取菜而变得黏糊的长手指”。这就表明了,但凡你用手抓着吃的东西,你用筷子也能吃;筷子很万能。实际上,他们在太空中比在地面上要更好使!不相信我?看看宇航员东佩蒂特是怎么用筷子喝茶的吧。

“But you canalso do that with a fork, or even a knife!”, I hear you say. Sure, but can youeat pieces of Cheetos straight out of the bag with a fork and a knife? Exactly!

“但你用叉子,甚至刀也能这样干!”我会听到你如是回答。没错,但是你能直接用刀叉吃掉袋子里的奇多(美国知名膨化食品品牌)吗?当然不能!

Here’s Don Pettit’s testimony of using chopsticks in space:

下面是佩蒂特对于在太空中使用筷子的看法:

“I like toeat with chopsticks, and I bring a pair on every flight. Like some prehensileextension of my fingers, they allow me to pull food out of its gooey pouchwithout getting sticky fingers. In weightlessness I can manipulate a huge chunkof food — maybe an agglomeration of ravioli that would normally fall apartunder the influence of gravity. Here the pieces stay loosely connected, like aminiature collection of asteroid debris.”

我喜欢用筷子吃饭,我每次上天前都会带上一双。筷子就像是我手指的延伸,而且很好抓握,他们让我可以在不弄脏双手的情况下把吃的从它们那黏糊糊的大袋子里拿出来。在失重环境下我可以夹住很大块的食物——即使是一团在无重力下很容易分解的意式馄饨(译注:?)借助筷子,食物可以松散地保持聚合,就像迷你小行星碎片堆那样。

Could you do that with a fork and a knife?

这些你用刀叉也能做得到吗?

Answered May 26
Imagine yourhand had a really long index finger and thumb and how useful that would be forpicking up food? Now imagine they were detachable and you could clean themready for your next meal.

想象下你拥有非常长的食指和大拇指,这对于抓取食物该有多大的用处?现在想象他们还可以分开好让你清洗它们来为下顿饭做准备。

This is exactlywhat chopsticks are. Super long, detachable fingers and thumbs for eating food.

你脑海里想象的这幅画面正是筷子的样子。炒鸡长,可拆卸的,用来吃饭的食指和大拇指。

They’re notactually part of your body, you don’t even need to make your hands a mess frompicking up food.

他们实际上并不是你身体的一部分,因此你不用担心它们被食物给弄脏。

It also helpsthat Chinese cooking tends to chop food into the perfect sizes perfect forgrabbing with your finger and thumb-like sticks.

这同样也促使饭菜通常会被做成了易于被筷子夹起的大小。

⑹ 三年级日记 我的发明

有句谚语:「需要为发明之母」。看英国《每日邮报》网站上的一篇文章 (日期 2/27 刊登),内容是介绍一些无用的发明。看完这篇文章,虽然会觉得有些发明挺多此一举且感觉挺搞笑的;不过有些发明个人倒挺想买耶!可能是从来没看过、没用过这些产品,会觉得挺新奇啊! (红色者觉得自己应该是用不到)

1. 夹餐巾纸项链 (CAT NAPKIN CHAIN)

由两只猫形状做成的项鍊,用来防汤汁滴到衣服上。可以把它藏在衣服内,等进餐时用到,是不是很另类呢?是说你会想在脖子上挂上这东西吗?或许爱猫人士会因为那两只可爱的猫而购买吧!?

2. 披萨叉子 (PIZZA FORK)

这叉子除了可以帮你切披萨之外,还可以将它当叉子用。嘿~我吃披萨都是用手抓耶,这东西应该是发明给斯文人用的吧?

3. 宠物按摩器 (PET MASSAGER)

一款让人类忌妒的发明!阿猫阿狗真是好命,还有这种专门的按摩器啊!相信爱狗爱猫人士一定抢著买,抢到缺货罗~

4. 鱼儿训练器 (FISH TRAINING KIT)

你家有忧伤、孤僻自闭的鱼儿吗?没关系买了这套产品,可以让他走出孤寂~哇,这可不能让爱鱼成痴的老公看到,他肯定买来给他的鱼儿解闷啊!可以踢足球、投篮,好酷呢!

5. 哑铃闹钟 (SHAPE-UP DUMBBELL ALARM CLOCK)

闹钟在哪里呢?原来在哑铃的肚子里。早上闹钟响起时,只有当你连续向上推举30下哑铃后,闹钟声才会停止。它的目的是为了让懒虫早起健身。

不过遇上像我这样的懒虫,应该不管他三七二十一,还是将头蒙进被子里,继续呼呼大睡。

6. 手套靴子烘乾器

下雨或是从雪地里回到家手套或是靴子湿透了,此时这个烘乾器派上用场。冬天还真有这样的困扰,觉得湿湿的手套或是靴子总想把它烘乾,结果是用吹风机解决,但是效果不怎样,这器具老实说我会想买耶~

7. 厕所阅读桌 (THE LOO READ)

这个可伸缩的平台应该是造福了上厕所时喜欢看书报杂志的朋友吧!(我也是其中之一) 很方便耶~还可以用来玩拼图或是当化妆台。

8. 单手看书器

可以单手看书,另外一手忙著吃东西或是做别的事情,是说我单手就可以拿书了,干麻用这东西呀? 且到时翻书还是要用到另一手啊!不如发明一个自动翻书器?

9. 吹乾耳朵器

有必要吗?用毛巾不就好了?

10. 雷射剪刀

这项发明美意虽好,让人们剪纸时不需要担心剪不直,只要靠著这雷射线就可以剪出好线条,但是却有人批评若是手颤抖效果仍是不佳,没用过不知道耶。

11. 携带型冰淇淋球

你想吃冰且自己动手作吗?只要在这颗球内装入冰、奶精跟盐,把玩这个球大约二十分钟之后就有现成的冰淇淋享用~唉啊,买现成吃不就好了吗?

12. 狗狗护目镜 (Doggles)

让你的狗狗戴上这种眼镜,可以防紫外线阳光或是脏东西、昆虫跑进眼睛~呼真是好狗命啊

13. 电动冰淇淋盒

如果你是个爱吃冰淇淋,却是有点懒转动手腕舔冰淇淋的人,这个发明可以让你只伸出舌头去吃冰淇淋,不需要费力只需动口,实在看不出来这发明哪里好用耶~可能我不是那麼爱吃冰淇淋吧!

14. 分叉笔尾 (Pen Again)

据说使用这种人体工学发明的笔可以让疲劳远离你;不过我现在都不太用笔写字了啊,都是用打电脑比较多耶~

15. 长袍毯 (SLANKET)

长袍毯强调其「非常柔软、轻盈、舒适」,人们穿上它,就可以非常暖和地坐在沙发上看电视。那跟盖上一条普通毛毯看电视有什麼区别呢?

看完这几种发明,你觉得哪一种发明最不中用呢?哪一种发明会最想买呢?

如果有意思订购或是知道价格,请自行上此网站看这则新闻原文版 → 按我 每项发明后面都注明了销售网站。
