style="text-indent: 2em;">為了減小壺與冰面的摩擦，在比賽前會(huì)對(duì)冰面進(jìn)行打磨和灑水，“擦地”的動(dòng)作擦掉了水珠形成的冰點(diǎn)，減小了摩擦力。</p><p style="text-indent: 2em;">另一方面，運(yùn)動(dòng)員一般在投擲時(shí)會(huì)給冰壺一個(gè)旋轉(zhuǎn)角度，冰壺很多時(shí)候并不是直線向前的，“擦地+旋轉(zhuǎn)”也控制了冰壺的運(yùn)動(dòng)軌跡。</p><p style="text-indent: 2em;">規(guī)則規(guī)定，任何一方隊(duì)員都不得碰到在營(yíng)壘中靜止的冰壺或正在運(yùn)行中的冰壺。如碰到，則此壺作廢。不會(huì)重新再投擲，但所有受影響的壺都會(huì)被放回原位。(一般情況下，專(zhuān)業(yè)運(yùn)動(dòng)員都不會(huì)碰到，比賽中冰壺?cái)?shù)量有限，損失一個(gè)壺影響還是很大的)。</p><p style="text-indent: 2em;"><strong>冰壺比賽硬件要求</strong></p><p style="text-indent: 2em;">冰壺(Curling)又稱(chēng)擲冰壺，冰上溜石，是以隊(duì)為單位在冰上進(jìn)行的一種投擲性競(jìng)賽項(xiàng)目，被大家喻為冰上的“<a href='http://www.rzpgrj.com/xuexiaqi/guojixiangqi/' target='_blank'><u>國(guó)際象棋</u></a>”，它考驗(yàn)參與者的體能與腦力，展現(xiàn)動(dòng)靜之美，取舍之智慧，屬于冬奧會(huì)比賽項(xiàng)目。</p><p style="text-indent: 2em;">冰壺比賽場(chǎng)地長(zhǎng)44.5米，寬4.32米(從木框的內(nèi)緣算起)。冰道的一端畫(huà)有一個(gè)直徑為1.83米的圓圈作為球員的發(fā)球區(qū)，被稱(chēng)作本壘。冰道的另一端也畫(huà)有一圓圈，被稱(chēng)為營(yíng)壘。場(chǎng)地四周設(shè)有2英寸高、4英寸寬的木框，以防砥石溜出界外。在場(chǎng)內(nèi)有6條與端線平行的橫貫全場(chǎng)的橫線，中間的兩條稱(chēng)前衛(wèi)線，也稱(chēng)欄線;兩端的兩條稱(chēng)后衛(wèi)線。前衛(wèi)線的寬度為4英寸，后衛(wèi)線的寬度為l英寸。在前衛(wèi)線和后衛(wèi)線的中間有一個(gè)縱橫交叉的十字線，稱(chēng)圓心線，也稱(chēng)丁字線。圓心線的交叉點(diǎn)即是營(yíng)壘的中心點(diǎn)。以中心點(diǎn)為圓心，向外分別各畫(huà)一個(gè)半徑0.15米，0.61米、1.22米以及1.83米的同心圓圈，外面的兩圓之間涂為藍(lán)色，里面的兩圓之間涂為紅色。在場(chǎng)內(nèi)的兩端距離端線1.22米處各安裝有兩個(gè)高2英寸的斜面橡膠起滑架，投擲砥石就從這里開(kāi)始。起滑架的橡膠部分應(yīng)緊密固定在木質(zhì)或其他材質(zhì)的材料上。起滑架長(zhǎng)不得超過(guò)8英寸，內(nèi)側(cè)距離中心線為3英寸。</p><p style="text-indent: 2em;">比賽時(shí)，運(yùn)動(dòng)員要身著運(yùn)動(dòng)服，腳穿比賽鞋(或鞋套)，比賽鞋(或鞋套)兩腳的底部不同，蹬冰腳鞋的底部為橡膠，而滑動(dòng)腳鞋的底部則為塑料。</p><p style="text-indent: 2em;"><strong>冰壺比賽球員位置</strong></p><p style="text-indent: 2em;">為避免擁擠，比賽規(guī)則對(duì)于球員的位置也有所規(guī)定：</p><p style="text-indent: 2em;">1.非擲球隊(duì)：主將及副將可站立于標(biāo)的端之底線后方，主將也可立于擲球隊(duì)之主將之后。下一順位之?dāng)S球員可站在后板附近，而其他球員則可站在冰道底端之后或兩欄線之間。</p><p style="text-indent: 2em;">2.擲球隊(duì)：持冰刷之主將(或副將)可立于標(biāo)的端圓心線后方之任何位置。</p><p
