By compared with the simulation results and the experiment results, we come to the conclusions that : ( 1 ) circuit with assistant network can widen soft - switching extent in lagging arm, reduces duty - cycle loss on the secondary, diminishes switching dissipation of inverter spot - welding power source. ( 2 ) the range of resonant capacitor, the important factor to soft - switching process, not only affects zero - voltage turn - off of power switches, but also affects the range of zero - voltage turn - on of power switches. so resonant capacitors must be considered according to many aspects ; ( 3 ) it easily fulfils soft - switching condition in lagging arm as leakage inductance of power transformer increases, but bigger leakage inductance of power transformer increases opening dissipation of transformer and decreases efficiency of soft - switching inverter power source
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。 -

This thesis pass through the laser delimitation instrument and the geological radar instrument means, to tunnel initial stages support and secondary structure. at past the research of tunnel lining thickness depend on opening dig figure, don " t consider the effect of tunnel lining inner figure. adopting the integrate method of the laser delimitation instrument and the geological radar could most exact reflect the change rule of tunnel lining thickness, but also could do lots unbroken examination, have very important for summing - up the rule of tunnel lining thickness change, and have very amplitude extend value
本文通過激光限界儀和地質雷達綜合方法，對新建高速公路隧道初期支護和二次襯砌混凝土內輪廓和厚度進行了檢測，對襯砌厚度的分佈規律以往的研究中，多以開挖和襯砌的輪廓變化為依據，並未考慮襯砌內輪廓的影響，而採用激光斷面輪廓限界儀和地質雷達綜合方法能較為準確的反應襯砌厚度的變化規律，並且能夠無破損的做大量的檢測工作，為總結混凝土厚度的規律有很大作用，並有極大的推廣價值。 -
For the dual register burner, while cat being applied, it simulates the influences of the flow field in the burner by changing the velocities of primary flow and inner / outer secondary flows, and by changing the opening percents of inner / outer vanes. eventually, the appropriate values for velocities and opening percents of vanes are recommended, to provide engineering problems with theoretical orientations
針對雙調風旋流燃燒器，本文運用計算機輔助試驗（ cat ）方法對一次風速度，內、外二次風的葉片開度及內、外二次風速度對燃燒器內流場的影響進行了數值試驗，得出了雙調風旋流燃燒器推薦使用的二次風葉片開度和速度值范圍，為工程應用提供了理論依據。 -
