各位大大幫我翻譯英文~~~我英文很糟~~~根本不會翻!!

The requirements for a global communications system are formed form

the demands for service imposed by potential or actual users.

These requirements include the numbers and locations of users, mode

of traffic,(voice , data, television,etc.),message generation rate,

message

length, quality ,reaction time, etc.

In the current communications plant,all of these factors have been

determined through experience and past perofrmance. In the case of

speech communications,this experience roughly corresponds

communications,this experience roughly corresponds to the mathematics of Erlang

and Molina .

System engineers are continually striving to improve the quality of

speech transmission(receive signal-to-noise ratio)

and the ability of the system to respond more rapidly .

Sincethe relative newness of digital communication has not allowed time to

determine its essential characteristics,system designers either rely on

Molina or treat digits as outside the bound f mathematics.

    構成全球通訊系統的必要條件在於潛伏或是現實使用者的需求,

    這些必要條件包括1.數字2.地區使用者3.交流方式(聲音.資料.電視.等等......)訊息速率,訊息速度,反應時間,等等......

    在現今的通訊業,所有的業者都取決於經驗以及過去的成果

    在言語通訊的個案中,上述的經驗大略上會和數學中的Erlang和Molina產生相對應

    系統工程師不停的努力提升言語傳送的品質(接收,信號到噪音干擾比例)和系統反應迅速的能力

    自從數位通訊的新奇已不在容許時間來決定他的特色於否,系統設計師必須仰賴molina不然就是把數位當作外來的數學領域
