What is Field-reversed configuration principle?
The principle behind Field-reversed configurations (FRCs) is the reversal of the plasma current and the ambient magnetic field in a plasma, which is the magnetic field that is present in the surrounding environment.
場反向位形(FRC)的原理就是在電漿體中，讓電漿體電流的方向與環境磁場的方向相反，而環境磁場為存在於周圍環境中的磁場。
The reversal of the plasma current and the ambient magnetic field can be achieved through a variety of methods, such as the injection of a high-energy beam or the application of an external current pulse.
電漿體電流和環境磁場的反轉可以通過多種方法實現，像是注入高能束流或施加外部電流脈衝。
Once the plasma current and the ambient magnetic field are reversed, the plasma becomes confined in a magnetic field, forming an FRC.
一旦電漿體電流和環境磁場反轉，電漿體就會被限制在磁場中，形成 FRC。
The formation and sustained of an FRC depends on a number of factors, including the strength and configuration of the external magnetic fields, the properties of the plasma, and the specific application.
FRC的形成和維持時間取決於許多因素，包括外部磁場的強度和配置、電漿體的特性以及其應用方式。
Advantage
FRC can be formed at relatively low temperatures, and they can be sustained for relatively long periods of time.
FRC可以在相對較低的溫度下形成，並且可以維持相對較長的時間。
They also have the potential to achieve high fusion gain, which is a measure of the efficiency of a fusion reaction.
他們還有可能實現”高聚變增益”，這是衡量聚變反應效率的指標。
Disadvantage
FRC are challenging to study and control,Such as material selection of confinement devices, precise control of output energy,and there is still much research being done to understand and optimize their behavior.
FRC在研究和控制方面還面臨許多挑戰性，像是侷限裝置的材料選擇、輸出能量的精確控制，並且還有許多研究正在進行中，以了解和優化操作他們的方式。
