One day Hubbard and Sanders learned that Bell had abandoned his " harmonic telegraph" and was experimenting with an entirely new idea.

有一天，哈伯德和桑德斯得知贝尔放弃了他的“谐波电报” ，并正在试验一种全新的想法。

Bell's harmonic telegraph immediately went into the discard, and the young inventor — Bell was then only twenty-nine — became a man of one passionate idea.

贝尔的谐波电报立即被废弃， 这位年轻的发明家——当时贝尔只有二十九岁——成为了一个充满激情的人。

An investigator who seems to have grasped more clearly the basic idea was the distinguished American inventor Elisha Gray, already mentioned as the man who had succeeded in perfecting the " harmonic telegraph" .

一位似乎更清楚地掌握了基本思想的研究者是杰出的美国发明家以利沙格雷，他已经被称为成功完善“谐波电报”的人。

Bell lived in Sanders's home for a considerable period, dividing his time between teaching his little pupil how to talk and puttering away at a proposed invention which he called a " harmonic telegraph" .

贝尔在桑德斯家里住了相当长的一段时间，他把时间分配在教他的小学生如何说话和搁置一项他称之为“谐波电报”的拟议发明上。

Sanders and Hubbard, much annoyed that Bell had abandoned his harmonic telegraph for so visionary an idea as a long distance talking machine, refused to finance him further unless he returned to his original quest.

桑德斯和賀伯特對貝爾放棄他的谐波電報而投棄他的谐波電報，因為像遠距發聲機器這樣有遠見的想法感到非常惱火，他們拒絕為他提供更進一步的資助，除非他回到他最初的追求。
