vibration-frequency measurement

基本解釋

So the ultra-low frequency absolute vibration detection is a difficult problem in engineering measurement field.
因此超低頻絕對振動檢測一直是工程測試領(lǐng)域的一大難題。
The low frequency, weak mechanical vibration experiments show that detection system can realize the non-contact measurement.
微弱機(jī)械振動信號的探測結(jié)果表明，該系統(tǒng)能實現(xiàn)無接觸測量。
Described in this paper is a newly developed portable computer-based vibration frequency measurement system for turbine blades.
采用以便攜式計算機(jī)為核心的新型汽輪機(jī)葉片頻率測量系統(tǒng)可大大提高測量的精確度和工作效率。
