为了物尽其用地充分发挥材料价值,人类自古以来就懂得把各种东西化整为零地使用,如胭脂、面粉、白糖等。这些材料加工成粉末更便于与其他成分混合,后来手段的不断改进使粉碎程度越来越细,需要的成分也更加容易为人体所吸收,用途也越来越广泛。如今病毒大小的物质也都可以控制其形状,甚至做出切片,对微粉的研究正在成为生活科技的前沿。
In order to make the best use of materials to give full play to the value of mankind since ancient times to understand the use of a variety of Eastern things to zero, such as rouge, flour, sugar and so on. The processing of these materials into powder is easier to mix with other ingredients, and subsequent improvements in the means make the degree of comminution more and more fine. The required ingredients are more easily absorbed by the body and are used more and more widely. Now the size of the virus material can also control its shape, and even make a slice, the study of the powder is becoming the forefront of life science and technology.
