In this thesis, to increase the aspect ratio of liga process, several important influence factors were discussed, which includes the structure and performance of liga mask, x - ray intensity and x - ray spectrum of beam lines, the characteristic of pmma resin and the micro electroforming parameters. the au - pi mask and the au - si mask were designed by xop and origin software, after the difference between the spectrum of 3w1 and 3b1 beam line had been contrastively analyzed
本文著眼于liga技術高深寬比方面的研究,以提高本實驗室用liga技術製作微細結構的深寬比為目的,從分析各因素影響深寬比的機理出發,再加以理論設計和實驗工藝的優化和改善,分別研究討論了影響深寬比的幾大重要因素:掩模結構和性能、光源光譜和光強、 pmma光刻膠性能、電鑄工藝參數等。 -
The task in the open loop system is to get lpg injection duty ratio in pre - set two dimension map according to practical engine operation condition, while the task in the closed - loop system is to calculate lpg injection duty ratio by the approaching increment method or the proportion and integral ( pi ) controller according to the signal of the oxygen sensor. to eliminate the oscillation phenomena of the signal of the oxygen sensor in low - speed condition, this paper develops the stable increment method
開環階段根據實時工況參數對事先制取的噴氣占空比map圖執行取值操作;閉環階段根據氧傳感器反饋信號通過增量逼近法或pi環節計算輸出適合即時工況的噴氣占空比值;為解決低速振蕩現象,本文運用固定增量法,對系統進行低速振蕩微調。
