一、弓的種類有哪些

弓的種類有很多，按照(zhao)時代可以分(fen)為傳統(tong)弓(gong)和(he)現代弓(gong)，其(qi)中(zhong)傳統(tong)弓(gong)包括和(he)弓(gong)、英格蘭(lan)長弓(gong)、秦弓(gong)、蒙古(gu)弓(gong)、韓弓(gong)等(deng)；按照(zhao)弓(gong)型可以分(fen)為反(fan)曲弓(gong)和(he)直拉(la)弓(gong)，其(qi)中(zhong)反(fan)曲弓(gong)又(you)可以分(fen)為競技反(fan)曲弓(gong)和(he)狩(shou)獵反(fan)曲弓(gong)；按照(zhao)材料的不同可以分(fen)為單(dan)體弓(gong)和(he)復(fu)合弓(gong)，其(qi)中(zhong)單(dan)體弓(gong)是用一種材料制作而成，比(bi)如動物的角、竹木、魚膠(jiao)牛(niu)筋等(deng)。

弓是拋射兵器中最古老的(de)一(yi)種(zhong)彈(dan)射武(wu)器，其主要是由(you)兩部分組成(cheng)，分別是富有彈(dan)性(xing)的(de)弓臂和柔(rou)韌的(de)弓弦，其作用是將扣在弦上的(de)箭(jian)或彈(dan)丸射向遠(yuan)處的(de)目(mu)標。

二、反曲弓和直拉弓的區別

反(fan)曲(qu)(qu)弓(gong)(gong)(gong)(gong)和直拉(la)(la)弓(gong)(gong)(gong)(gong)的(de)(de)外觀不(bu)一(yi)樣，大(da)家用(yong)肉(rou)眼就可以看出來(lai)；反(fan)曲(qu)(qu)弓(gong)(gong)(gong)(gong)和直拉(la)(la)弓(gong)(gong)(gong)(gong)的(de)(de)弓(gong)(gong)(gong)(gong)片(pian)(pian)(pian)不(bu)一(yi)樣，反(fan)曲(qu)(qu)弓(gong)(gong)(gong)(gong)的(de)(de)弓(gong)(gong)(gong)(gong)片(pian)(pian)(pian)是(shi)向(xiang)其自(zi)(zi)然(ran)彎曲(qu)(qu)的(de)(de)反(fan)方向(xiang)上(shang)緊弓(gong)(gong)(gong)(gong)弦(xian)，利用(yong)曲(qu)(qu)度的(de)(de)彈性(xing)提供箭(jian)的(de)(de)動力。直拉(la)(la)弓(gong)(gong)(gong)(gong)的(de)(de)弓(gong)(gong)(gong)(gong)片(pian)(pian)(pian)則是(shi)順著弓(gong)(gong)(gong)(gong)片(pian)(pian)(pian)自(zi)(zi)然(ran)彎曲(qu)(qu)的(de)(de)方向(xiang)拉(la)(la)緊弓(gong)(gong)(gong)(gong)弦(xian)。

反(fan)曲弓(gong)(gong)弓(gong)(gong)片(pian)一(yi)般有兩種材(cai)質(zhi)(zhi)，一(yi)種層壓玻璃(li)鋼(gang)，一(yi)種是碳纖維(wei)；反(fan)曲弓(gong)(gong)初學者的(de)弓(gong)(gong)把(ba)多(duo)(duo)為(wei)(wei)胡桃木(mu)的(de)，訓練比(bi)賽的(de)多(duo)(duo)為(wei)(wei)碳鋁合金的(de)；直拉弓(gong)(gong)的(de)材(cai)質(zhi)(zhi)就簡單得多(duo)(duo)，弓(gong)(gong)片(pian)為(wei)(wei)塑木(mu)的(de)，弓(gong)(gong)把(ba)采用鑄鋁。

反曲弓在奧(ao)運會等重大賽事中的射箭項目中使用(yong)；直拉弓則多為旅游(you)景點、公園、度假村、垂釣(diao)中心、農家(jia)樂(le)農莊等休閑、娛樂(le)的場所(suo)選用(yong)。

反曲弓因為是國(guo)際比賽的弓(gong)型，配件也復雜的多，有箭臺、箭側墊、防震桿(gan)、瞄準(zhun)器(qi)(qi)、信號片、穩定桿(gan)等；直(zhi)拉弓(gong)是比較休閑的弓(gong)箭產品，所以配件就(jiu)只(zhi)有基本的箭臺、簡(jian)易瞄準(zhun)器(qi)(qi)。
