When the natural frequency of the gas column in the inlet valve is consistent with the main frequency of the periodic air inlet noise, the resonance noise of the gas column will also become prominent in the air inlet noise
進氣管空氣柱的固有頻率與周期性進氣噪聲的主要頻率相一致時，空氣柱的共振噪聲在進氣噪聲中也會較為突出。Doubting the resonance condition of the longitudinal vibration of the sucker rod string introduced by apirp11l and improving of the mechanical modeling
抽油桿柱縱向振動共振條件的質疑與力學模型的修正Most resonant mass detectors are made of large, cylindrical aluminum bars
大多數共振質量探測儀是由巨大的圓柱形鋁棒構成。The characteristics of the intrinsic frequency distribution of the framed steam turbine - generator set foundation are summarized ; it can been seen that the base plate of the framed foundation does not have much effect on the dynamic response of the foundation, and that the " amplitude method " is better than the " resonance method " among dynamic analysis methods. when designing a framed foundation, as long as the load - bearing capacity and stability is ensured, a flexible pillar is better, the amplitude of vibration can be controlled through adjusting the particle quality in foundation design
論文最後總結了框架式汽輪發電機組基礎固有頻率的分佈特點；指出框架式基礎底板本身對基礎的動力響應影響不大，認為動力分析方法中振幅法優于共振法；並指出框架式基礎設計時，在滿足承載力和穩定性的前提下，柱子應以柔為佳；設計中可以通過調整質點的質量來達到控制基礎振幅的目的。The exhaust noise contains complex noise elements, including the exhaust noise with a base frequency measured in the number of exhausts in unit time, the resonance noise of the gas column in the pipe, the gas stream blowing noise at the exhaust manifold, the exhaust gas jetting and impact noise, the helmholtz resonance noise of the cylinder, the karman eddy noise and the turbulent noise inside the exhaust system
排氣噪聲包含了復雜的噪聲成分：以單位時間內排氣次數為基頻的排氣噪聲、管道內氣柱共振噪聲、排氣歧管處的氣流吹氣噪聲、廢氣噴注和沖擊噪聲、汽缸的亥姆霍茲共振噪聲、卡門渦流噪聲及排氣系統內部的湍流噪聲等。Free resonance vibration column test
自共振柱試驗Standard test methods for modulus and damping of soils by the resonant - column method
用共振柱法測定土壤的模量和阻尼因數的標準試驗方法The directivity coefficient of the phased array antenna has been generalized and discussed. according to the formulations of microstrip antenna design theory, planar and cylindrical microstrip patch cell has been analyzed. we can conclude that the cylindrical microstrip patch cell has the performance of high gain, low thickness, high resonant frequency, uniform directivity diagram, and easy fabrication on missile body, so it is a good choice
本文根據微帶天線設計理論，分析了平面和柱面兩種微帶貼片單元，其中柱面微帶貼片單元增益高、厚度小、諧振頻率高、方向圖均勻，且較易加工製作在彈體上，適合在相控陣天線中做共形輻射單元。By the data observed on - site, it indicate that the reinforcing plan which the plant to disembark and the dam to be connected has solved the problem that the plant to disembark occurs resonance vibration with the frequency of the turbogenerator units, but the problem of resonance vibration of the downriver structure of the plant has not been solved, hence the study of the reinforce structure of the downriver plant must be made
廠房在此長期嚴重的振動下，立柱出現水平周邊裂縫，門窗墻壁也均產生裂縫，威脅到電站的安全運行。現場測試表明上游廠壩間在一定范圍內連接加固，雖然解決了廠房上游一階頻率與轉頻的共振問題，但對下游結構作用不明顯，因此需要對廠房下游結構的加固作進一步的研究。Power plant structures have very strong professional characteristics because of its craft reasons, for example, the plane stiffness and vertical stiffness are not uniform, strong beam and weak column structures are often used, different types of members are used together, and the vibration problems are very serious, etc. all of this make the inspecting and appraising and strengthening of power plant structures have special characteristics, such as, there have no appropriate codes or standards to be used, the particularities of power plant structures and the special requirements of power industry must be thought about
火力發電廠結構因工藝原因具有很強的行業特點，比如：平面剛度不均勻；豎向剛度不均勻；強梁弱柱大量出現；不同種類構件共同使用；振動問題嚴重等。這些問題的出現也造成了針對電廠結構進行的檢測、鑒定和加固的特殊性，比如：沒有合適的標準和規范可供使用；檢測、鑒定和加固應考慮電廠結構的特殊性；要考慮電力行業的特殊要求等。Resonant column test
