金字是上下结构,偏旁部首是金。
释义:
金,最早见于金文,金本义为赤金,即铜,引申为金属总称,后词义缩小指黄金。金在古代又作货币用,故又引申为货币。黄金在自然界储量稀少,故又指高贵、贵重之物等。
金字明显演变为从“今”声,是从秦印和《说文》小篆开始的,汉初篆文及秦汉简帛古隶书形体也承袭这一形体,但两汉成熟的隶书“金”字形体地许从秦印篆文那样的形体来,也许从春秋战国那样的形体来。
篆文、隶书基本承续金文字形。有的隶书将早期隶书的“今”省去一横,写成不知所云的字形,导致字形费解。

Golden word is fluctuation structure, character components radicals by which characters are arranged in traditional Chinese dictionaries is gold.
Paraphrase:
Gold, see Yu Jinwen the earliest, golden original meaning is pure gold, namely copper, extend the meaning is metallic floorboard, acceptation shrinks after little finger gold. Gold makes a money use again in ancient time, reason extend the meaning is a money. Gold is in nature reserves is scarce, reason points to high, rich other people to wait again.
Golden word evolves apparently for from " today " sound, be imprint from the Qin Dynasty and " say civil " an ancient style of calligraphy begins, body of ancient official script of Han Chuzhuan article and Qin Han Jian Bo also adopy this one body, but two Chinese mature official script " gold " glyph body ground is made from Qin Yinzhuan article in that way body comes, from age the Warring States perhaps in that way body comes.
Seal article, official script is basic bear glyph of add inscriptions on bronze. Some official script will be inchoate of official script " today " leave out one horizontal stroke, write into the glyph of not know what is said, bring about a glyph incomprehensible.

1.The structure of high-pressured switch is main wait for composition by transformer of switch of control system, breaker, ground connection, electric current, voltage transformer. 2. Controlling a system is the core of high-pressured switch, will control the switch state of switch through controlling a system, breaker is the main component of high-pressured switch, be used at disconnecting or receive electrify grade, ground connection switch is used at ground connection fault current, voltaic transformer and voltage transformer are used at detecting electric current and voltage size. 3. The structure of high-pressured switch and composition are to make sure the safety of power system and stability move, also be to satisfy the different requirement of power system at the same time and of the design. In applying actually, the power system that because differ,the structure of high-pressured switch and composition also meet and differ somewhat.
