答:架設單打球場球網時應注意:網柱要安裝準確。網柱應是直徑不(bu)超(chao)過15厘米(6英寸(cun)(cun))的(de)圓(yuan)柱或邊長不(bu)超(chao)過15厘米(6英寸(cun)(cun))的(de)正方形(xing)。網柱高不(bu)得超(chao)過網繩頂(ding)部2.5厘米門英寸(cun)(cun))。網柱中心距邊線外沿0.914米(3英尺)。球網要掛好。
球網(wang)(wang)懸掛在(zai)直(zhi)徑(jing)不(bu)超過(guo)0.3厘(li)米(1/3英寸(cun))的繩(sheng)(sheng)或(huo)鋼(gang)絲(si)繩(sheng)(sheng)上(shang),球網(wang)(wang)兩(liang)端懸掛在(zai)網(wang)(wang)柱上(shang),掛上(shang)網(wang)(wang)后兩(liang)端高度(du)(繩(sheng)(sheng)或(huo)鋼(gang)絲(si)繩(sheng)(sheng)上(shang)沿(yan)到地(di)(di)面(mian)的高度(du))應(ying)為(wei)(wei)(wei)1.07米(3英尺6英寸(cun)),中(zhong)間高度(du)為(wei)(wei)(wei)0.914米(3英尺),并(bing)用(yong)不(bu)超過(guo)5厘(li)米(2英寸(cun))寬(kuan)的白色中(zhong)心(xin)帶繃緊束于地(di)(di)面(mian)。雙打網(wang)(wang)柱應(ying)安裝(zhuang)在(zai)網(wang)(wang)柱中(zhong)心(xin)距(ju)雙打場地(di)(di)邊(bian)線(xian)外沿(yan)0.914米(3英尺)的位置上(shang),掛上(shang)球網(wang)(wang)后網(wang)(wang)繩(sheng)(sheng)或(huo)鋼(gang)絲(si)繩(sheng)(sheng)的頂(ding)部(bu)距(ju)地(di)(di)面(mian)的距(ju)離應(ying)為(wei)(wei)(wei)1.07米(3英尺6英寸(cun)),球網(wang)(wang)中(zhong)央(yang)高度(du)為(wei)(wei)(wei)0.914米(3英尺),并(bing)用(yong)白色中(zhong)心(xin)帶繃緊束于地(di)(di)面(mian)。
