4、p><p>　　由相關(guān)文獻(xiàn)和網(wǎng)上資料調(diào)查得知：國(guó)外對(duì)網(wǎng)球發(fā)射器的研究開(kāi)始得相對(duì)較早，最早的專利是1998年美國(guó)的Rose發(fā)明的。此后，各國(guó)紛紛開(kāi)始投入此項(xiàng)研究，其中美國(guó)、英國(guó)和日本占主導(dǎo)地位，技術(shù)成熟，且有一些產(chǎn)品已經(jīng)投入市場(chǎng)使用。此外，國(guó)外對(duì)網(wǎng)球接發(fā)球的研究要細(xì)膩得多，除了通過(guò)對(duì)蹬地轉(zhuǎn)體到鞭打等增加發(fā)球時(shí)速的一系列動(dòng)作的研究外，更是要求如何在發(fā)球的過(guò)程中，是核心力量更集中，逐漸由上步的動(dòng)作改為不上步。我國(guó)對(duì)此類裝置

5、的研究雖然起步較晚，但近些年來(lái)也涌現(xiàn)出了很多這方面的想法和創(chuàng)意，但是并沒(méi)有申請(qǐng)國(guó)家專利。目前我國(guó)的大部分網(wǎng)球發(fā)射器生產(chǎn)廠家還是應(yīng)用國(guó)外的網(wǎng)球發(fā)射技術(shù)。我國(guó)的網(wǎng)球發(fā)射技術(shù)既不先進(jìn)也不十分成熟。</p><p>　　國(guó)內(nèi)市場(chǎng)主流的網(wǎng)球發(fā)球機(jī)品牌有TENNIS TUTOR和LOBSTER，通過(guò)圖2-1你可以看出它們?cè)谇安慷加袀€(gè)出球口，通過(guò)出球口可以看見(jiàn)兩個(gè)輪子，就是這兩個(gè)由電機(jī)帶動(dòng)的輪子通過(guò)快速旋轉(zhuǎn)將球擠壓射出。所區(qū)別

8、球發(fā)射器的世界里，美國(guó)的發(fā)球機(jī)科技是最為先進(jìn)的。其發(fā)射器獨(dú)有的自動(dòng)模式功能能夠?qū)崿F(xiàn)全場(chǎng)的任意發(fā)球；并可以調(diào)節(jié)難度級(jí)別。仿真性非常強(qiáng)，適合各種水平的選手進(jìn)行專業(yè)的訓(xùn)練?？梢匀我庹{(diào)節(jié)發(fā)球的高度，如平擊球，高吊球等。也可根據(jù)使用者的要求需要選擇定點(diǎn)發(fā)球和多檔搖擺功能等。還有專用遙控機(jī)，實(shí)現(xiàn)遠(yuǎn)程的控制。其內(nèi)部有減震和靜音裝置，能夠有效降低噪音。這用發(fā)球發(fā)射器對(duì)于初級(jí)者和晉級(jí)者都能提供最大的輔助。</p><p><
