副產(chǎn)品技術(shù)
一些人會(huì)懷疑有些國家在太空項(xiàng)目上花費(fèi)數(shù)百萬美元是為什么。他們想知道太空研究如何能使地球上的人們受益。實(shí)際上，太空技術(shù)給地球上人們的日常生活帶來了便利。我們稱之為“副產(chǎn)品技術(shù)”，即現(xiàn)在地球上使用的太空技術(shù)。
在早期的太空計(jì)劃中，如20世紀(jì)60年代和70年代的阿波羅計(jì)劃，和今天的航天飛機(jī)計(jì)劃中，科學(xué)家們開發(fā)了供宇航員們?cè)谠虑蛏虾吞罩惺褂玫奈锲?，其中有一些成了我們今天日常生活中使用的物品。例如，我們現(xiàn)在使用的石英鐘和石英表的精確度達(dá)到了一年誤差不超過一分鐘。我們使用原本為宇航員設(shè)計(jì)在太空中使用的濾水器來凈化我們的飲用水。我們家里使用的電池式手提工具，如真空吸塵器、手電筒、鉆子和鋸子，都來自這些早期太空計(jì)劃中的技術(shù)。
在寒冷的冬日里，我們可以戴上由干電池提供熱能的手套和襪子、穿上隔熱材料做的外套和夾克來保暖。所有這些衣服都類似于為了使宇航員在月球上的溫度條件下保持身體舒適的太空服，都是太空技術(shù)的副產(chǎn)品。
這些產(chǎn)品只是我們的日常生活如何從太空技術(shù)中受益的幾個(gè)例子。沒有人知道源自于國際空間站的副產(chǎn)品技術(shù)會(huì)在未來給我們的生活帶來什么樣的好處。
Lesson30 Spin-off Technology
Some people wonder why countries spend millions of dollars on space projects. They want to know how space research helps people on Earth. Actually space technology helps people on Earth every day. This is called "spin-off technology."
Spin-off technology is space technology that is now used on Earth.
In early space programs, such as the Apollo missions of the 1960s and 1970s, and in the Space Shuttle missions today, scientists developed objects for the astronauts to use on the moon and in space. We now use some of these objects every day.
For example, we have Quartz crystal clocks and watches with accuracy of one minute a year. We purify the water we drink with a water filter designed for the astronauts' use in space.
The cordless, hand-held tools we use in our homes, such as vacuum cleaners, flashlights, drills and saws came from the technology of these early space programs.
On cold winter days we can stay warm with battery-operated gloves and socks, and insulated coats and jackets. All of these clothes are similar to the spacesuit designs that kept astronauts comfortable in the temperatures of the moon, and are spin-offs from space technology.
These products are only a few examples of the many ways space technology helps us in our everyday lives. No one knows how new spin-off technology from the International Space Station will help us in the future.
