摘要：
Method for maintaining and regulating the frequency of a timepiece resonator mechanism (1) around its natural frequency (ω0).A regulator device (2) acts on said resonator (1) with a periodic motion which requires a periodic modulation of at least the resonant frequency of said resonator (1), by requiring at least a modulation of the active length of a spring comprised in said resonator mechanism (1), with a regulation frequency (ωR) which is comprised between 0.9 times and 1.1 times the value of an integer multiple of said natural frequency (ω0), said integer being greater than or equal to 2 and less than or equal to 10.
摘要（中）：
用于在其固有频率（ω0）周围保持和调节钟表谐振器机构（1）的频率的方法。 调节器装置（2）以周期运动作用在所述谐振器（1）上，所述周期性运动需要至少对所述谐振器（1）的谐振频率进行周期性调制， 所述谐振器机构（1）具有调节频率（ωR），其在所述固有频率（ω0）的整数倍的值的0.9倍和1.1倍之间，所述整数大于或等于2并小于或等于2， 等于10。
