日本一名工程师设计了一台利用阳光和光化学作用发动的小型发动机。在透光的塑料汽缸内装有用活动活塞压缩的二氧化氮。在阳光的作用下,二氧化氮分解成一氧化氮和氧,汽缸中的压力因此而增加起来——活塞升起来。当活塞上升到1m高处时,汽缸壁被蒙上一层不透阳光的屏,一氧化氮和氧重新化合,又形成二氧化氮。汽缸中压力减弱,活塞便往下降。然后,不透光屏自动打开,整
An engineer in Japan designed a small engine that uses sunlight and photochemical action. In the light-transmissive plastic cylinder is equipped with active piston compression of nitrogen dioxide. Under the action of the sun, nitrogen dioxide decomposes into nitrogen monoxide and oxygen, and as a result the pressure in the cylinder increases - the piston rises. When the piston rises to a height of 1m, the cylinder wall is covered with a layer of opaque screen that re-combines nitric oxide with oxygen to form nitrogen dioxide. The pressure in the cylinder is weakened and the piston goes down. Then, opaque screen automatically open, whole
