Discussion on some protection problem about power line operating with phase failure ;2. This article describes phasor diagram analysis on two sides of 10 kV distribution transformer with phase failure operation by symmetrical component method.

针对10kV配电变压器的缺相运行，采用对称分量法对变压器高、低压侧断线分别进行了分析，得出各侧电压、电流的各序分量，较全面总结了配电变压器非全相故障运行特征。

CV indicated that the HOMO of DP1 is higher than that of DP2, which is resulted from the special effects of the pyrenes at C9 of the fluorene moieties, and the PL spectra of the two materials showed bright blue emission.

器件ITO／TCTA(8nm)／DP1 or DP2(30nm)／BCP(40nm)／Mg∶Ag都发出蓝光，但以DP1为发光材料的器件的性能远高于以DP2为发光材料的器件的性能，直流电压-电流曲线显示材料DP1有比DP2更高的载流子迁移率，芴9位的芘是造成这种结果的关键原因，并对这种原因进行了探讨。

Therefore, adding gassing material can improve the post current zero dielectric recovery strength.

说明在弧后金属栅片灭弧室能够承受较高的恢复电压，熄弧性能优于多纵缝陶土灭弧室。

Second, the turn on occurs in voltage minimum due to quasi resonant switching, which results in lower spectrum in higher frequency range.

第二，开通发生在准谐振开关电压的最小值，这导致更高频段频谱中更低的幅值。
