Smart Paper Ends Up Killing Trees
森林救星
ANCHOR
Something called e-paper is designed to combine the best features of a computer display screen and a plain old piece of paper. James Hattori shows us what it can do and what is still on the drawing board.

有一种纸叫电子纸张，它结合了电脑显示屏和普通纸张的优良特性。詹姆斯·哈托利为我们展示它的功能，还有仍然处于草图阶段的产品。
JAMES HATTORI, CNN CORRESPONDENT
Shoppers at this New Jersey department store probably didn’t realize it but the children’s section display was a true sign of the future – an electronic sign on electronic paper with information updated by computer wirelessly, so customers always see the latest and correct price.
詹姆斯·哈托利，CNN特派记者
在这家位于新泽西州的百货商店的购物者也许并没有发现这种电子纸张，但是在儿童区的显示屏却是未来真实写照——一种显示在电子纸张上的电子标牌，上面的信息可通过电脑遥控更新，所以顾客总是能看到最新的、准确的价格。
NICHOLAS SHERIDON, GYRICON MEDIA
These signs can be used for years over and over again. And so you don’t have to print the signs up. And you’ve got the convenience of one person in the store being able to handle all of the signs in the store.
I was trying to develop a display that could be used in a …
尼古拉斯·谢里顿，GYRICON传播公司
这些标牌能够反复使用多年。我不用把价格标签打印出来。店中只要有一个人就可以方便地处理所有的价格标牌。
我打算开发一种显示屏能够用于……
HATTORI
Nicholas Sheridon invented e-paper 25 years ago while working for the Palo Alto Research Center, formerly part of Xerox. Now Gyricon Media, a spin-off company ahs developed it for commercial use.
哈托利
尼古拉斯·谢里顿25年前发明了电子纸张，当时他就职于帕洛阿尔托研究中心，原属于施乐公司，目前一个派生公司，GYRICON传播公司，开发这种电子纸张的商业用途。
SHERIDON
We are actually looking at the edge of a sheet of electric piece of paper. You can actually see the balls moving up and down in the cavities.
谢里顿
实际上，我们从电子纸张的一侧看过去，你可以看到里面的小球在洞里上下运动。
HATTORI
The paper actually contains tiny plastic balls, which are about the width of a human hair between two sheets of plastic. There are hundreds of thousands of balls per square inch – each in this case half white and half black.
Depending on the charge it either shows the white side up or the black side up?
哈托利
这种纸张实际上内置很小的塑料小球。这些置于两层塑料之间的塑料球的直径和人们的头发丝差不多。电子纸张每平方英寸有数十万小球，每个小球都是这样一半白一半黑。每个小球根据电量大小显示白面朝上或是黑面朝上吗？
SHERIDON
That’s correct.
谢里顿
正确。
HATTORI
The balls pivot and form characters or shapes when an electric charge is applied. A computer converts words and images into electric signals.
哈托利
通电时，小球旋转组成文字或图形。电脑把文字和图像转换成电子信号。
GREG SCHMITZ, PALO ALTO RESEARCH CENTER
We have our print head here. We’re going to print this image and our information is going to come through here.
格雷格·史密兹，帕洛阿尔托研究中心
我们这儿有自己的打印头。我们准备打印这张图像，然后我们的信息就会从这儿出来。
HATTORI
Which are imprinted on the paper as it passes over a print head. The characters remain on the paper until it’s reprinted.
The print can be produced in various sizes. It could be handheld or part of a sign phrase.
哈托利
当电子纸张经过打印头时图像就印在这张纸上。文字一直保留在纸上，直到重新打印。
打印出来的纸张可以是不同尺寸。它可以手持或是标牌短语的一部分。
SHERIDON
This is a roll of what we call smart paper.
谢里顿
这是一卷我们所说的“智能纸张”。
HATTORI
Sheridon says the cost of producing smart paper has come down to about $1 a square foot in any two colors. Full color is still years away. So its another potential use – replacing the printed newspaper.
哈托利
谢里顿称，生产这种智能纸张的成本已经降到任何两种颜色的大约每平方英尺一美元。全彩纸还需要时日。那么它的另外一种潜在的用途——就是替代印刷的报纸。
ERIC SHRADER, PALO ALTO RESEARCH CENTER
The notion is… you end up killing trees so we’re in the actually delivery process of the paper making that electronic.
埃里克·史拉德，帕洛阿尔托研究中心
这种理念是……你不用伐木，因此我们在生产一种电子化纸张。
HATTORI
Gyricon is negotiating with a major department store to roll out the electronic signs chain-wide with hopes the rest of the industry will see the writing on the wall.
哈托利
GYRICON公司在和一家大型百货商店商讨在连锁店范围内铺开电子标牌，以期待其他商家能看到店铺墙面上这些标牌文字。
