Then, suddenly, came the sharp click of the tapper as it struck the coherer. 鲁伯特·萨金特·荷兰.历史性发明.
The coherer _j_ has two metal pole pieces, _j1 j2_, separated by silver and nickel filings. Edward W. Byrn.十九世纪发明进展.
This was in 1894, and the combination of oscillator and coherer actually formed the first real wireless set. 鲁伯特·萨金特·荷兰.历史性发明.
The coherer, invented by Branly in 1891, is a glass tube containing metal filings between two circuit terminals. Edward W. Byrn.十九世纪发明进展.
Professor Oliver Lodge named this device of Branly’s a coherer, and when he found that it was more sensitive than the Hertz detector he combined it with the Hertz oscillator. 鲁伯特·萨金特·荷兰.历史性发明.
The wave falls on conducting material and, the spark gap being replaced by a coherer, the metallic filings magnetically cling together, closing the relay circuit, so that a signal is made. 佚名.神奇的知识之书.
On breaking the current, a slight tap on the coherer or other means breaks the cohesion of the filings and the relay circuit is broken. 佚名.神奇的知识之书.
