    基片集成波導的基本概念是利用基片的上下金屬板和兩排間隔一定距離的金屬孔構成波導的金屬壁，由於每排金屬孔孔間距遠小於波長，因此由縫隙泄漏的能量很小，這相當于內部填充了介質的矩形波導，所以能夠用矩形普通波導實現的結構也都可以用基片集成波導來實現，比如功分器、濾波器、天線、耦合器、振蕩器等。

    結果表明，如果腔場無損耗且處于真空庫，則量子態周期性地顯現出一定的非局域性；如果考慮到腔場的損耗和熱庫的平均光子數，那麼，量子態將會喪失它初始的非局域性，初始量子非局域性喪失的速度與初始腔場的幅度、腔的衰減系數以及熱庫的平均光子數有關，場越強、平均光子數和衰減系數越大，量子非局域性喪失得就越快。

    通過模擬結果與軟開關點焊逆變器試驗結果的對比分析，得到了如下主要結論：採用輔助網路可以完全拓寬全橋軟開關逆變器的滯后橋臂軟開關范圍，減小了次級占空比丟失，降低了逆變電阻點焊電源的開關損耗；諧振電容是影響軟開關工作狀態的重要因素，其大小不僅影響開關管的零電壓關斷，同時也影響開關管的零電壓開通范圍，因此，諧振電容應該綜合考慮；功率變壓器漏感越大，越容易滿足滯后橋臂的軟開關條件，但是大的漏感也使變壓器的通態損耗增加，降低了軟開關逆變器的效率。
