Laying is the skill of making equipment level. It usually involves moving equipment in small motions so that spirit levels are centralised in all planes. Movement is usually done by small worm gears or other fine setting devices for accurate small movements, together with other more coarse gears to allow large swings in motion for quick movement between different settings. Equipment that requires laying before it is can be used accurately includes: * theodolites * guns and howitzers in the indirect fire mode ==See also== * Gun laying 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「Laying」の詳細全文を読む スポンサード リンク
