求大神指导,石英晶体微天平?看了一些关于 石英晶体 微天平的资料,但始终没搞明白底下这些英语的表达,这里的5M HZ, 25M HZ, 都表示的是什么?求大神指导。 A gold-coated 5 MHz??AT-cut crystal was excited at its fifth overtone at 25 MHz, and the change in the resonance frequency was recorded. The resulting frequencies were divided by 5 to be comparable to the results at the base frequency (5 MHz).查看更多3个回答 . 13人已关注
