Also new to the Obama bookshelves are three mechanical devices on loan from the National Museum of American History's patent collection: models for Samuel Morse's 1849 telegraph register, John Peer's 1874 gear-cutting machine and Henry Williams' 1877 feathering paddlewheel for steamboats.

此外，书架上还增添了从美国历史博物馆借来的三件机械专利藏品，分别是1849年萨缪尔·摩尔斯发明的电报机模型，1874年约翰·皮尔发明的齿轮加工机床模型，以及 1877年亨利·威廉姆斯发明的汽船活叶明轮模型。

Teletypes, or teletypewriters, were originally printer-keyboard combinations that read and sent information over a serial line, not too different from an ancient telegraph machine.

Teletypes，或者 teletypewriters，原来指的是电传打字机，是通过串行线用打印机键盘通过阅读和发送信息的东西，和古老的电报机区别并不是很大。

At the same time Morse was perfecting the telegraph, the first real electrical system, Rudolf Clausius codified the basic idea of the second law of thermodynamics, which has haunted the entire history of electronics.

与此同时，摩尔完善了第一台真正的电气系统—电报机，Rudolf Clausius把热动力学的第二定律编成了基本思想的法典，它折磨着整个电子学的发展历史。
