摘要结合强夯振动监测的应用实例，阐述了强夯振动监测的原理方法和成果分析过程，以及强夯振动监测应注意的问题。 - It discusses some kinds of basic frequency synthesis technology such as direct , phase - lock , digital and direct digital frequency synthesis , then give the performance index of the frequency synthesis , and discusses the digital frequency synthesis technology in detail
讨论了直接式频率技术、锁相式频率合成技术、数字式频率合成技术、直接数字频率合成技术等几种基本频率合成技术，给出的衡量频率合成技术的各种性能指标，并对全数字频率合成技术作了较详细的讨论。 - The preceding five steps modal frequencies and the corresponding vibration modals of the main frame are calculated . by means of the comparison basic frequency with the other vilration sources and the analysis of each other step vibration modes , the structure is proved to be safe this dissertation studied the important mechanism of the roadheader
求出其5阶固有频率和振型，将固有频率与振源频率比较，并对各阶振型进行动态观察与分析，得出了其在正常工作时不会发生共振的结论。 - Through analysis of natural frequencies and seismic response by means of response spectrum method for such building structure with different suspension mass pendulums , it was concluded that optimal damping effect would be obtained when a few suspended mass pendulums with similar frequency as the structural basic frequency fixed on the top stories of the high building
通过对具有不同悬吊质量摆的高层建筑结构的自振特性及反应谱法地震反应分析，得出在高层建筑结构顶部几层设置几个质量摆且质量摆的频率和结构的基频相近时减震效果最好。 - Compared with non - passerine , they appeared longer syllable length , higher basic frequency and more viable frequency ranges . though the amplitude modulation properties enhanced their vocal production , the type of syllable is still stable and less of variety . so the phrase consisted of syllables are comparatively few and changes of the tone are relatively less
且表现出很强的频率调制特性和特有的幅度调制特性，相对的音节时程比较长，基频较高且频率变化范围较大，所特有的幅度调制特性更增加了其控声的能力，但其音节的种类仍很单一，缺乏变化，由音节所组成的句型较少，音调变化幅度不大，因此，其叫声质量尽管较非鸣禽有所改善，但相对鸣禽而言却又远远不如。
