Current density doubles when the area of effective contact between tissue and electrode is halved,provided that HF current remains contant. 如果高頻電流強度保持不變，那么人體組織和電極之間的有效接觸面積減半將會(huì )使電流密度增大一倍，這將產(chǎn)生四倍的熱量。
As a result,it is found that the electric current of EMC is related with ingot size,and the electromagnetic press balances with the static press of liquid metal. 本文推導了電磁鑄過(guò)程中的磁感應強度表達式，并由此導出了電流強度與鑄錠尺寸的關(guān)系式，計算的電磁壓力與液體金屬的靜壓頭基本平衡。
Austin uses a Tessler coil to raise the voltage while lowering the current. 奧斯丁使用了特斯拉線(xiàn)圈來(lái)加強電壓，同時(shí)卻也降低了電流量。
The loss is proportional to the amount of current being carried, so utilities keep the current low and compensate by raising the voltage. 由于電力耗損與傳輸的電流量成正比，所以電力公司必須降低電流，同時(shí)提高電壓來(lái)加以彌補。
