闸 🔊

网络内容摘要 (Web Content Summary):

闸（拼音：zhá）本意是“截水的门”，即用来控制水流的设施，如水闸。该字为象形会意字，从“门”加上“甲”形，形象地表示一道关门，用于拦截或控制流动。简体字“闸”源自繁体字“閘”，其字形演变可追溯到汉代，最早见于《马王堆汉墓帛书》。 “闸” (pinyin: zhá) originally means “a sluice gate,” a structure used to control water flow. The character is pictophonetic, combining the “door” radical with the “armor” shape, symbolizing a gate that blocks or manages flow. The simplified form “闸” comes from the traditional “閘”, and its earliest records date back to the Han dynasty (Mawangdui manuscripts).

• 常用意义： 除了水闸外，“闸”也引申为用来控制流动的各种开关，如“电闸”（electric switch），表示断开或接通电流的装置。 Main uses: Beyond “sluice gate,” “闸” is also used for devices that control flow, such as “电闸” (electric switch), referring to circuit breakers.
• 易混淆点： “闸”与“坝”（dam）容易混淆，但“闸”强调的是“门”的功能，主要用于控制流动（如水流、电流）；“坝”是蓄水或挡水的建筑物。 Easily confused: “闸” and “坝” can be confused. “闸” refers to the controlling “gate,” while “坝” is the “dam” used to block or store water.
• 常见词语： 水闸（sluice gate）、电闸（circuit breaker/switch）、闸门（gate, esp. for water/slurry control）。暂无常用成语。 Common words: 水闸 (sluice gate), 电闸 (circuit breaker/switch), 闸门 (gate for controlling water or similar flows). There are no common idioms using this character.

文化背景： 闸的起源与水利工程有关，体现了中国古代对自然资源的管理智慧。 Cultural note: The character “闸” originates from hydraulic engineering, reflecting ancient Chinese wisdom in managing natural resources.
