一、弓的種類有哪些

弓的種類有很多，按(an)照(zhao)時代可(ke)以(yi)分(fen)為傳統(tong)弓(gong)(gong)(gong)和現代弓(gong)(gong)(gong)，其(qi)中(zhong)(zhong)傳統(tong)弓(gong)(gong)(gong)包括和弓(gong)(gong)(gong)、英格蘭長弓(gong)(gong)(gong)、秦弓(gong)(gong)(gong)、蒙古弓(gong)(gong)(gong)、韓弓(gong)(gong)(gong)等；按(an)照(zhao)弓(gong)(gong)(gong)型(xing)可(ke)以(yi)分(fen)為反曲(qu)弓(gong)(gong)(gong)和直拉弓(gong)(gong)(gong)，其(qi)中(zhong)(zhong)反曲(qu)弓(gong)(gong)(gong)又可(ke)以(yi)分(fen)為競技反曲(qu)弓(gong)(gong)(gong)和狩獵反曲(qu)弓(gong)(gong)(gong)；按(an)照(zhao)材料的不(bu)同(tong)可(ke)以(yi)分(fen)為單體弓(gong)(gong)(gong)和復合弓(gong)(gong)(gong)，其(qi)中(zhong)(zhong)單體弓(gong)(gong)(gong)是用一(yi)種材料制作而成，比如動物的角、竹木、魚(yu)膠牛(niu)筋等。

弓是拋射兵器中最古老(lao)的(de)一種彈射武器，其主要(yao)是由兩部分組成，分別是富有彈性的(de)弓臂和柔韌的(de)弓弦，其作用是將(jiang)扣在(zai)弦上的(de)箭或彈丸射向(xiang)遠處(chu)的(de)目(mu)標。

二、反曲弓和直拉弓的區別

反(fan)曲(qu)弓(gong)(gong)和直拉弓(gong)(gong)的(de)外觀(guan)不(bu)一樣，大家(jia)用(yong)肉眼就可(ke)以看出(chu)來(lai)；反(fan)曲(qu)弓(gong)(gong)和直拉弓(gong)(gong)的(de)弓(gong)(gong)片(pian)不(bu)一樣，反(fan)曲(qu)弓(gong)(gong)的(de)弓(gong)(gong)片(pian)是(shi)向其(qi)自然彎曲(qu)的(de)反(fan)方向上(shang)緊(jin)弓(gong)(gong)弦(xian)，利用(yong)曲(qu)度的(de)彈性提供箭(jian)的(de)動力。直拉弓(gong)(gong)的(de)弓(gong)(gong)片(pian)則是(shi)順(shun)著(zhu)弓(gong)(gong)片(pian)自然彎曲(qu)的(de)方向拉緊(jin)弓(gong)(gong)弦(xian)。

反曲(qu)弓(gong)(gong)(gong)弓(gong)(gong)(gong)片一般有兩(liang)種材(cai)質，一種層(ceng)壓玻(bo)璃鋼，一種是(shi)碳纖(xian)維；反曲(qu)弓(gong)(gong)(gong)初學者的(de)弓(gong)(gong)(gong)把多(duo)為(wei)胡桃木(mu)的(de)，訓練比賽(sai)的(de)多(duo)為(wei)碳鋁(lv)合(he)金的(de)；直拉弓(gong)(gong)(gong)的(de)材(cai)質就簡單得多(duo)，弓(gong)(gong)(gong)片為(wei)塑木(mu)的(de)，弓(gong)(gong)(gong)把采(cai)用鑄鋁(lv)。

反曲弓在奧運會等重大賽事(shi)中的射箭項目中使用(yong)；直拉弓則多為旅游景(jing)點(dian)、公園、度假村、垂釣中心、農家樂農莊等休閑、娛樂的場所選(xuan)用(yong)。

反曲弓因為是國(guo)際(ji)比賽的弓(gong)型(xing)，配件(jian)也(ye)復雜的多，有箭(jian)臺、箭(jian)側墊、防(fang)震桿(gan)、瞄(miao)準器、信號片、穩定桿(gan)等；直拉弓(gong)是比較(jiao)休閑的弓(gong)箭(jian)產品，所以配件(jian)就只有基本的箭(jian)臺、簡易瞄(miao)準器。
