Аннотация

Статья посвящена анализу современных достижений в проблеме потерь энергии в пьезокерамических резонаторах. Параллельно презентуется новая простая методика экспериментального определения коэффициентов потерь энергии и святи и приводится  мнение автора, почему механическая добротность на резонансе и антирезонансе разная. Причина состоит в «зажатой» емкости и в величине коэффициента электромеханической связи. Чем лучше электромеханическая связь, тем сильнее «зажата» емкость и тем выше ее влияние на антирезонансную частоту и добротность.
