在科技史上,有许多发明和发现是几个人几乎同时独立完成的,为此常常闹出一些纠纷和恩怨,电话的发明就是一例。实际上,历史发展到某个阶段,这种多人争夺优先权的现象是正常的。 In the history of science and technology, there are many inventions and discoveries that have been made by several people almost independently at the same time. To this end, some disputes and grievances are frequently raised. The invention of the telephone is an example. In fact, it is normal for such people to compete for priority as the history reaches a certain stage.
