一、弓的種類有哪些

弓的種(zhong)類有(you)很多，按(an)照時代可(ke)以(yi)(yi)分(fen)(fen)為傳統(tong)弓(gong)和(he)(he)現代弓(gong)，其中傳統(tong)弓(gong)包括和(he)(he)弓(gong)、英格蘭長弓(gong)、秦弓(gong)、蒙古(gu)弓(gong)、韓(han)弓(gong)等；按(an)照弓(gong)型(xing)可(ke)以(yi)(yi)分(fen)(fen)為反曲(qu)弓(gong)和(he)(he)直(zhi)拉弓(gong)，其中反曲(qu)弓(gong)又可(ke)以(yi)(yi)分(fen)(fen)為競技反曲(qu)弓(gong)和(he)(he)狩獵反曲(qu)弓(gong)；按(an)照材料的不(bu)同可(ke)以(yi)(yi)分(fen)(fen)為單(dan)(dan)體(ti)弓(gong)和(he)(he)復合弓(gong)，其中單(dan)(dan)體(ti)弓(gong)是用(yong)一種(zhong)材料制作(zuo)而成(cheng)，比如動物的角(jiao)、竹木、魚膠牛筋(jin)等。

弓(gong)是(shi)(shi)拋(pao)射兵(bing)器中(zhong)最(zui)古(gu)老(lao)的一種彈射武器，其(qi)主(zhu)要是(shi)(shi)由兩部分組(zu)成，分別是(shi)(shi)富有彈性的弓(gong)臂和柔韌的弓(gong)弦(xian)，其(qi)作用是(shi)(shi)將扣在弦(xian)上的箭或彈丸射向遠處的目標。

二、反曲弓和直拉弓的區別

反(fan)曲(qu)(qu)弓(gong)(gong)(gong)(gong)和(he)直(zhi)拉(la)弓(gong)(gong)(gong)(gong)的外觀不一(yi)樣，大(da)家用肉眼就可(ke)以看出來；反(fan)曲(qu)(qu)弓(gong)(gong)(gong)(gong)和(he)直(zhi)拉(la)弓(gong)(gong)(gong)(gong)的弓(gong)(gong)(gong)(gong)片不一(yi)樣，反(fan)曲(qu)(qu)弓(gong)(gong)(gong)(gong)的弓(gong)(gong)(gong)(gong)片是向其自(zi)然彎曲(qu)(qu)的反(fan)方向上緊弓(gong)(gong)(gong)(gong)弦，利(li)用曲(qu)(qu)度(du)的彈性提供箭(jian)的動力。直(zhi)拉(la)弓(gong)(gong)(gong)(gong)的弓(gong)(gong)(gong)(gong)片則是順著弓(gong)(gong)(gong)(gong)片自(zi)然彎曲(qu)(qu)的方向拉(la)緊弓(gong)(gong)(gong)(gong)弦。

反曲(qu)(qu)弓弓片(pian)一(yi)般有兩種材質(zhi)(zhi)，一(yi)種層壓玻璃鋼，一(yi)種是碳纖維；反曲(qu)(qu)弓初學者的(de)(de)(de)(de)弓把多(duo)為(wei)胡桃木的(de)(de)(de)(de)，訓練比(bi)賽的(de)(de)(de)(de)多(duo)為(wei)碳鋁(lv)合金的(de)(de)(de)(de)；直拉弓的(de)(de)(de)(de)材質(zhi)(zhi)就簡(jian)單得多(duo)，弓片(pian)為(wei)塑木的(de)(de)(de)(de)，弓把采用鑄鋁(lv)。

反曲弓在奧運會等重大(da)賽事(shi)中的(de)射箭項目中使用；直拉弓則(ze)多為旅游景(jing)點、公(gong)園、度假村、垂釣中心、農家樂農莊等休閑、娛樂的(de)場(chang)所選(xuan)用。

反曲弓因為是國(guo)際比賽的弓型(xing)，配件也復雜的多(duo)，有(you)箭(jian)臺、箭(jian)側墊、防震桿(gan)(gan)、瞄準(zhun)器、信(xin)號片、穩定(ding)桿(gan)(gan)等(deng)；直拉弓是比較休閑的弓箭(jian)產品(pin)，所以配件就只有(you)基本的箭(jian)臺、簡易瞄準(zhun)器。
