採用真空滅弧室，空氣絕緣配以電動彈簧操動機構，使得產品滅弧能力強，短路開斷次數高，無火災爆炸危險，操作方便，是一種性能優良，實用性較強的產品。The characteristics of damping shows that the uncompensated parallel ac transmission line can release the coupling between the hvdc and generator and improve the damping of the system, hence the possibility of subsynchronous oscillation decrease. in such a system scheme, the hvdc system dominates the changes of damping due to the small magnitude of the damping provided by ac line. when the ac transmission line is compensated with a fixed series capacitor, the situation will be totally different
其中，並列運行的無串補交流輸電線路可以緩解hvdc與其臨近機組之間的機電耦合程度，改善hvdc的電氣負阻尼特性，從浙江大學博士學位論文摘要而減輕機組發生次同步振蕩的危險性，此時系統的整體電氣阻尼特性由hvdc的性質決定;但若交流線路中存在串聯補償電容，則系統幅值較大的電氣負阻尼不僅可能使整流站機組發生次同步振蕩，逆變站附近機組同樣存在發生次同步振蕩的可能性，此時系統的整體阻尼特性由串聯補償電容的性質決定。This thesis mainly studies the drawbacks of the internet cafe in macau and the reason of which, lists out the adverse effects brought about to the youths by the unregulated internet cafes, including damage on health, environmental safety, crime commission, and also leads to psychological health damage. this is because in the virtual internet world, youths live in virtual environment which easily leads to youths closing up themselves at human relationship, thus resulting in isolation on family and social relationship and generating lonely character ; in addition, youths have weak sense of self control and self protection, they lack the ability to prevent danger. once they indulge themselves in the internet cafe overnight for long, this will cause great damage to their academic performance, health and thinking, the internet cafe becomes youths " " nursery bed of crime ", and " electronic cocaine " that harms them
本論文主要探討澳門現行網吧之弊端以及其產生之原因，羅列無規管的網吧給青少年帶來身體健康的傷害、環境安全的侵害、違法犯罪的危害外，還會導致心理健康的損害；因為，在虛擬的網路世界中，青少年活在虛構的環境下，容易造成人際關系的封閉，引致親子關系及人際關系的疏離，使青少年養成孤僻性格，加上自我控制能力和自我保護能力意識薄弱、危險防預能力缺乏，一旦通宵達旦沉湎於網吧，對其學業、健康和思想造成很大的危害，更成為青少年「罪惡的溫床」 ，荼毒青少年的「電子海洛因」 。
