Transmission Lines 原文翻譯@@

希望能幫我把翻譯改順@@~

謝謝~

6.3第二部分@@~有很多部份~希望能有行動通訊專業人士解惑~~

按我的名子裡面很多@@感謝~再次感謝~每題都是20點~

=====================================

=CHAPER 6 -Page 169=

When high power is used it is important to keep the interior of the line dry, so these lines are sometimes pressurized with nitrogen to keep out moisture.

Coaxial cables are referred to as unbalanced lines because of their lack of symmetry with respect to ground (usually the outer conductor is grounded)

當大功率被使用它重要保持線的內部乾燥, 因此這些線有時被加壓與氮氣保持在濕氣之外。

同軸電纜被稱為失衡的線由於他們的缺乏對稱談到地面(外面導管通常被著陸)

Parallel-line transmission lines are also common.

They are not used for signal transmission as frequently as coaxial cable because they tend to radiate energy into space and also to antenna arrays.

Ordinary television twin-lead, as shown in Figure 6.3(a), is an example of a parallel transmission line.

Parallel lines can be shielded to reduce interference problems, as illustrated in Figure 6.3(b).

平行線傳輸線並且是共同性。

他們像同軸電纜一樣頻繁地不被使用為信號傳輸因為他們傾向於放熱能量入空間和並且對天線列陣。

普通的電視正如被顯示在上圖6.3(a), 一條並行傳輸線的雙胞胎帶領, 例子。

平行的線可能被保護減少干涉問題, 依照被說明在表6.3(b) 。

Parallel lines are usually operated as balanced lines; that is, the impedance to ground from each of the two wires is equal.

This ensures that the currents in the two wires will be equal in magnitude and opposite in sign, reducing radiation from the cable and its susceptibility to outside interference.

Coaxial cable, on the other hand, is inherently unbalanced and should be used with the outer shield grounded.

When properly used, there is no connection between the signal currents in the cable, which travel on the outside of the inner conductor and the inside of the outer conductor, and any interference currents, which are only on the outside of the outer conductor.

平行的線通常被管理作為平衡線; 那是阻抗對地面從每個二根導線是相等的。

這保證, 電流在二根導線將是相等的在巨大和對面在標誌, 減少輻射從纜繩和它的感受性對外部干涉。

同軸電纜, 另一方面, 是固有地失衡的, 應該被使用與外面盾被著陸。

當適當地使用, 沒有連接在信號電流在纜繩, 傳導在內在導管的外部和外面導管的裡面, 並且所有干涉電流之間, 是只在外面導管的外部。

    When high power is used it is important to keep the interior of the line dry, so these lines are sometimes pressurized with nitrogen to keep out moisture.

    Coaxial cables are referred to as unbalanced lines because of their lack of symmetry with respect to ground (usually the outer conductor is grounded)

    當使用於大功率時保持線(管線)的內部乾燥是很重要的, 因此有時這些線會以氮氣加壓來防止(排除)濕氣。

    同軸電纜被稱為不均衡(對等)的線,因為以對地(地線)而言他們不是對稱的(外層導線通常接地)

    Parallel-line transmission lines are also common.

    They are not used for signal transmission as frequently as coaxial cable because they tend to radiate energy into space and also to antenna arrays.

    Ordinary television twin-lead, as shown in Figure 6.3(a), is an example of a parallel transmission line.

    Parallel lines can be shielded to reduce interference problems, as illustrated in Figure 6.3(b).

    平行(線)傳輸線也是很普遍的。

    他們不像同軸電纜一樣常被使用為信號傳輸,因為他們容易放射(流失)能量於空間和天線列陣。

    普通的電視雙導線,正如上圖6.3(a)所示, 為一種平行傳輸線的例子。

    平行的線可以以包覆的方式來減少干擾的問題, 如同圖6.3(b)所示 。

    Parallel lines are usually operated as balanced lines; that is, the impedance to ground from each of the two wires is equal.

    This ensures that the currents in the two wires will be equal in magnitude and opposite in sign, reducing radiation from the cable and its susceptibility to outside interference.

    Coaxial cable, on the other hand, is inherently unbalanced and should be used with the outer shield grounded.

    When properly used, there is no connection between the signal currents in the cable, which travel on the outside of the inner conductor and the inside of the outer conductor, and any interference currents, which are only on the outside of the outer conductor.

    平行的線通常以平衡線的方式使用; 二條導線的對地阻抗是相等的。

    這確保, 二條導線中電流的強度相等且相位相反, 同時減少放射和其受外部干擾的程度。

    反觀同軸電纜, 是承襲非對稱特性, 外層導線應該要接地。

    當適當地使用時, 電纜中的外層訊號和內層訊號電流之間是不會有任何的連繫, 所有的干擾訊號會被隔絕在外層導線之外。
