Specification of non - synchronized opening and closing multi - jaw double ropes grab for handling scrap iron or block material 異步啟閉式多顎板廢鋼塊料雙索抓斗技術(shù)條件
When not in a synchronized method . surround the code to be synchronized in a synchronized block within a non - synchronized method and call 將那些需要同步的代碼包在一個(gè)同步塊中,里面不含有非同步的方法,并且在這些同步代碼塊之外才調(diào)用
Be sure to not synchronize code that makes blocking calls , or make sure that a non - synchronized method exists on an object with synchronized blocking code 必須確保不在同步代碼中包含那些阻塞調(diào)用,或確認(rèn)在一個(gè)用同步阻塞代碼的對象中存在非同步方法。
With the increased availability of computer network as well as the development of network technology , distance education based on cooperative enviroment has become the new highlight of the distance education technology . as one of the most important applications of computer supported cooperative work ( cscw ) , the internet - based synchronized system of electronic whiteboard has been increasingly demonstrating its advantage over the non - synchronized distance education system . in a synchronized electronic whiteboard system , the teachers will be able to carry out their courses in a very easy way , like what they have done in a conventional classroom enviroment 作為計(jì)算機(jī)支持的協(xié)同工作( cscw )的重要應(yīng)用之一,基于internet的同步電子白板系統(tǒng)逐漸體現(xiàn)出較傳統(tǒng)異步方式下的遠(yuǎn)程教學(xué)系統(tǒng)更優(yōu)越的方面。在同步電子白板系統(tǒng)中,老師可以象平常上課一樣,在一個(gè)虛擬的教室環(huán)境中方便的進(jìn)行教學(xué),免去了為了實(shí)現(xiàn)遠(yuǎn)程教學(xué)而必須掌握復(fù)雜的課件制作技術(shù)的麻煩,并且在同步的環(huán)境中更加強(qiáng)了和學(xué)生的互動(dòng)以及對學(xué)生的管理,因此在目前的校園網(wǎng)內(nèi)具有極大的推廣意義。
