发明是技术和生产活动的起点,有了打制石器、人工取火的发明和应用,才开始了人类物质生产和社会生活的历史。社会历史的发展,离不开发明创造。为了我们人类的未来更加美好,各国科学家都在致力于改变人类生活的新发明。这些新发明让我们的生活更方便,也让我们的生活更有趣。真空行李箱出门旅行是现代人的最爱,为了在外面尽量过得舒服,每个人都希望多带一些衣物。可是,再大的行李箱似乎都装不下想要带的东西。为此,热爱旅游的英国科学家正在研制一种真空行李箱。这种真空行李箱分3层,每层都装有一个独立的抽气装置。真空行李箱里面还有一个自动的压力装置,可以把箱子里的衣服压缩到最小状态。经过压缩的真空行李箱看上去和普通箱子一样大,却能装下比普通箱子容量大3倍的东西。
Invention was the starting point of technology and production activities. With the invention and application of stone making and artificial fire-taking, the history of material production and social life of human beings began. The development of social history can not be separated from invention and creation. For the betterment of our human future, scientists all over the world are devoting themselves to changing new inventions of human life. These new inventions make our life easier and make our life more interesting. Vacuum travel luggage is the favorite of modern people, in order to get as comfortable as possible outside, everyone hopes to bring some more clothing. However, the big luggage seems to fit no more than what they want to bring. To this end, the British travel enthusiasts are developing a vacuum baggage. This vacuum trunk is divided into three layers, each floor is equipped with a separate extraction device. There is also a vacuum inside the automatic pressure device, you can put the clothes in the box is compressed to a minimum. The compressed vacuum trunk looks just as big as a regular box, yet it holds about three times as much as a regular box.
