求翻译：特性阻抗會受其材料及結構的影響，對於電線設計來說，沒有一個固定的計算公式，只有根據經驗寫出的一個理論公式，材料不同，遮蔽不同都會有很大影響，每個電線公司的公式都是類似，附檔計算公式請參考，公式只能計算出一個理論值，實際還是依測試為准，以上請知悉，謝謝!是什么意思？

Characteristic impedance will be affected by the material and structure design for the wire , there is no fixed formula , only on the basis of a theoretical formula written experience , different materials , different shelter will have a great impact on the company of each wire

The characteristics impedance will receive the influence of its material and structure, regarding the electric wire design, does not have a fixed formula, a theoretical formula that only then writes according to the experience, the material will be different, camouflages differently will have very t

The characteristic impedance can receive its material and the structure influence, regarding the electric wire design, does not have a fixed formula, only then a theoretical formula which writes according to the experience, the material is different, the camouflage different all can have the very tr

Characteristics impedance will by its material and the structure of effects, for wire design for, no a fixed of calculation formula, only according to experience wrote of a theory formula, material different, covered different will has is big effects, each wire company of formula are is similar, att
