海军信号旗
naval signal flag
hailun xinhaoqi海军信号旗(naval signal nag)在目力范围内进行旗语通信的专用旗帜。亦称海军通信旗。是视觉通信中重要的通信器材之一。主要供舰艇和海岸信号台使用。白天，目力能看清的地方均可用它来传递信号。通信距离一般为2一3海里。其用途是传达舰艇编队的统一号令，进行海上编队运动或表示本舰的行动信号，也可发送日常勤务信号。海军信号旗是挂在旗杆上的旗帜，用1面或几面旗帜表示某种含义。分字母旗、数字旗和特种旗3种。根据颜色和式样来识别。用红、黄、蓝、白、黑5种不同颜色的旗纱缝制而成，式样分为燕尾形、长方形、三角形和梯形。以其尺寸的大小分为4一5种规格。结构上分为旗面、旗头布、旗绳和旗钩4部分。国际信号旗由26面字母旗、10面数字旗、3面代旗和1面回答旗共40面旗组成。多数国家海军信号旗的式样、数量与国际信号旗基本相同。中国人民解放军海军信号旗除增加6面特种旗外，其他和国际信号旗相同(见海军旗帜)。 (蔡长庚)
