做机械一辈子，你知道机械的定义吗？

一切具有确定的运动系统的机器和机构的总称

Any machine and mechanism with a defined motion system

是指机器与机构的总称。机械就是能帮人们降低工作难度或省力的工具装置，像筷子、扫帚以及镊子一类的物品都可以被称为机械，他们是简单机械。而复杂机械就是由两种或两种以上的简单机械构成。通常把这些比较复杂的机械叫做机器。从结构和运动的观点来看，机构和机器并无区别，泛称为机械。

Refers to machines and mechanisms. Is the machinery can help people reduce the difficulty of the work or saving device, like chopsticks, broom and tweezers items can be referred to as machinery, they are simple machines. The complex machinery is composed of two or more than two simple machinery. These complex machines are usually called machines. From the point of view of the structure and motion mechanism and machine, there is no difference between general machinery.

机械，源自于希腊语之Mechine及拉丁文Machina，  原指“巧妙的设计”，作为一般性的机械概念，可以追溯到古罗马时期，主要是为了区别与手工工具。现代中文之“机械”一词为机构为英语之（Mechanism）和机器（Machine）的总称。机械的特征有：机械是一种人为的实物构件的组合。机械各部分之间具有确定的相对运动。故机器能转换机械能或完成有用的机械功，是现代机械原理中的最基本的概念，

Machinery, derived from the Greek Mechine and Latin Machina, originally referred to as "ingenious design", as a general mechanical concept, can be traced back to the ancient Rome period, mainly to distinguish between hand tools. The term "machinery" in modern Chinese is the general term for English (Mechanism) and machinery (Machine). Mechanical characteristics are: machinery is a man-made physical component combination. The relative motion between the parts of the machine. Therefore, the machine can convert mechanical energy or complete useful mechanical work, is the modern mechanical principle of the most basic concept,
