根据法国交通部公布的资料,80%的汽车轮胎气压不足,由于这原因去年在法国公路上死亡45人,重伤137人。此外,轮胎气压不足还会使燃料多消耗2.5%,外胎磨损增加25%。一名法国发明家率先在汽车每个轮子的外壳上安装一个简单的气压表。气压表与内胎固定相连,它通过带有三段颜色——绿色、黄色和红色的表盘指示气压值。当指针超过绿色段范围时,说明该给轮胎打气了。日本一家公司研制了一种配有录音机的电子摇篮。将婴儿放摇篮里,只要他一哭,摇篮就开始摆动,同时响起父母亲哄小孩的声
According to information released by the French Ministry of Transport, 80% of the tires in the car are under-pressured, resulting in 45 deaths and 137 injuries last year on French roads. In addition, under-pressured tires can result in 2.5% more fuel consumption and 25% more tire wear. A French inventor took the lead in installing a simple barometer on the shell of each wheel of a car. The barometer is permanently attached to the inner tube and indicates the barometric pressure via a dial with three colors - green, yellow and red. When the pointer exceeds the range of the green segment, it means that the tire cheer up. A Japanese company developed an electronic cradle with a recorder. The baby in the cradle, as long as he cried, the cradle began to swing, while sounded the sound of parents and children to coax children
