Besides, in case the vortex shedding frequency is equal to a vibration frequency of structure, the rod will occur the vortex shedding resonance or called vortex resonance.
并且当漩涡脱落频率与杆件的固有频率接近时，杆件会产生漩涡脱落共振或称涡激共振。
An offset cross structure for supporting secondary mirror is proposed. The structure has a higher resonance frequency so it can be applied to large-aperture telescope.
提出了次镜支撑的偏置十字型中心结构，该结构具有较高的谐振频率，因此可以用于大口径望远镜中。
