The experiment results reveal that all the breakdown main bodies are located at the pointedness and insulation joint of magnet wires. 試驗結果表明，擊穿點主體都是位於電磁線試樣稜角和絕緣接縫處。
The yield point represents the dividing line or transition from the elastic to the plastic region of the curve. 屈服點是彈性變形區域到塑性變形區域之間曲線的過渡點。
In order to ensure that the structure is stable, the working stresses are kept well below the yield point or the proof stress. 為了保證結構穩定，工作應力應很好地保持在屈服點或彈性極限以下。
