我们都知道,脚蹬是由彼埃尔和埃尔内斯特·米肖父子俩首先制成的,人们很难断定脚蹬是属于一大发明还是一大发现。如果我们认为操纵杆的原理已不复存在,米肖父子俩只是采用了这个操纵扦并把它转移到德耐式(一种木制无链条自行车)自行车的车轮上。那我们就视之为一大发现;如果我们说这两个系统装置的合二为一创造了第三个装置——脚蹬。那我们就可——称之为一大
We all know that the pedals were first made by Pierre and Herniz de Misuchs, and it is hard to tell whether the pedals belonged to a great invention or a great discovery. If we think the principle of the joystick no longer exists, both Mishcha and the father simply use the manipulator and transfer it to the wheel of a bike of Dene (a wooden chainless bicycle). Then we see it as a big discovery; if we say that the combination of the two system devices creates the third device - the pedal. Then we can - call it a big one
