翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Ultrasonic antifouling ： ウィキペディア英語版 Ultrasonic antifouling Ultrasonic antifouling is a technology that helps reduce fouling on underwater structures, through using small-scale acoustic cavitation to destroy, denature and discourage attachment of algae and other single-celled organisms. ==History== The technology is believed to have been created by the US Navy in the 1950s: during sonar tests on submarines, it was discovered that the areas surrounding the sonar transducers were cleaner than the rest of the hull. Since then, research has been conducted into the effectiveness of different frequencies and intensities of ultrasonic waves on various marine life, such as barnacles, mussels and algae. Commercial ultrasonic systems have been used to control algal blooms in ponds, harbours and reservoirs.〔("LG Sonic Tholen harbour" )〕 In controlling the algae, the first stage in the fouling sequence is halted, acting as a prevention, rather than a cure as with traditional anti-fouling paint. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ultrasonic antifouling」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
