vibration-frequency measurement

基本解释

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.
微弱機械振動信號的探測結果表明，該系統能實現無接觸測量。
Described in this paper is a newly developed portable computer-based vibration frequency measurement system for turbine blades.
採用以便攜式計算機爲核心的新型汽輪機葉片頻率測量系統可大大提高測量的精確度和工作傚率。
