1. First of all is how to dissipate heat which rises from the rectifying bridge, inductance of input filter, switches, transformer, rectifying tubs of output filter and output bus. 首当其冲的是如何散热，必须考虑散热的器件包括：输入整流桥、滤波电抗器、开关管、变压器、输出整流二极管以及母排等等。
2. In this paper, a method of optimizing reflux ratio in rectifying tower is introduced. An economical model of the rectifying tower and its solving approaches are also presented. 本文介绍一种精馏塔中适宜回流比的优化方法。给出了精馏塔的经济模型及相应的求解方法和求解过程。
3. Rectifying stage with diode or sckotty diode can't meet the needs of higher efficiency and lower size because forward drop of rectifier is great and rectifying dissipation is great in power converter. 传统的二极管整流电路因为正向压降大而导致损耗大、效率低，已无法满足低电压大电流开关电源高效率、小体积的需要。
4. Rectifying sets and twenty-four or forty-eight phase equivalent multiphase rectifying system should take first place in harmonic wave harness. 表述了将整流所整流机组与形成24相或48相等效多相整流系统，融入了谐波治理措施之首的观点。
5. Results After rectifying process, selected catheter was placed into the interstitial portion of the fallopian tube successfully in all cases. 结果经矫位后，全部病例均成功地完成选择性输卵管插管。
