矿井电网选择性漏电保护原理及装置的研究与设计

Currently , test is the main method of research on fatigue failure of MEMS , and there is no decice can be used to study on the fatigue failure of silicon micro-structure which is fabricated by bulk micromachining .

目前，进行硅微结构疲劳失效的研究主要以试验为基础，而现有试验装置无法研究体硅工艺制造的MEMS器件疲劳特性。

Conclusions Percutaneous PDA closure with the Amplatzer duct occluder decice is an safety and effective method for the treatment of PDA in infants , but caution shall be exercised to the anatomic characteristics in the infant age group in solving clinical complications .

结论Amplatzer导管封堵器治疗婴儿期PDA是一种安全有效的方法，但应注意该年龄组患儿解剖学特点，防止并发症的发生。
