1. The syntax function of "de" is very ample in Dongkou dialect. It can act as a verb or an auxiliary verb an auxiliary word or a modal particle or a word affix. 洞口方言中“得”的语法功能十分丰富,可以作动词、助动词、助词(包括能性助词、结构助词、完成体助词)、语气词及构词成分。
2. Auxiliary boiler is an auxiliary engine of a ship and a key auxiliary device for the ship. 辅助锅炉属于船舶辅机,是船舶配套关键设备。
3. Besides there is only one direction of zero modal current when shielding failure occurs, which makes zero modal voltage increases monotonically. 若发生绕击故障,零模电流只沿一个方向,使保护安装处零模电压在故障后一段时间内呈现单调变化。
4. Then, modal experiment of cabinet is carried out with impulse excitation method and corresponding modal parameters are obtained. 另外,用脉冲激励法对机箱进行模态实验,得到实验模态参数。
5. The modal properties including modal frequencies and mode shapes of the torsional oscillation system were calculated and analyzed with eigen analysis and impedance matching method. 用特徵分析和阻抗匹配方法对系统各个模态固有特性包括固有频率和振型进行了对比计算和结果分析。
