Therefore, the space charge reductionfactor equation based on the sheath helix model is inappropriate at high frequency.
因此，使用螺旋导电面模型在较高频段计算空间电荷降低因子是不合适的。

The resistance reductionfactor is suggested as a fixed value of 0.90, regardless of the strain level of the tensile steel reinforcement.
基于对抗力折减系数的参数研究结果，无论钢筋的应变水平如何，建议取固定值0.90。

The study shows that the difference of the space charge reductionfactor between the sheath model and the perfect conducting tube is small at high frequency.
