Finally presents the detecting and processing technique of exciting power and frequence. 重點(diǎn)介紹激振力和激振頻率的檢測(cè)和處理技術(shù)。
For example, top-down parsers are guaranteed to find every possible production, but can be extremely slow because of frequence (exponention order) backtracking. 例如，top-down 解析器可以確保找到每一個(gè)可能的產(chǎn)品，但 可能會(huì)非常慢，因?yàn)橐l繁地（指數(shù)級(jí)）進(jìn)行回溯。
This paper deals with a system consisted of machine, hydraulic and electronic being used to control loading power and frequence of the hydraulic vibration exciting unit. 本文闡述一種用于控制液壓激振裝置加載力和加載頻率的機(jī)液電系統(tǒng)。
