By the analysis of several gas forces in the twin - scroll compressor, the calculation formula of working volume and all different crank shaft angle are derived
摘要分析了雙頭渦旋齒渦旋盤所受的各種氣體力，提出了在任意曲軸轉角下的各種氣體力及工作腔容積的計算公式。In the part of the experimental designs, a experimental configuration of an unstable cavity by use of two bbo crystals compensating the walkoff effect and pumped by reflection is presented, and two set of controlling systems designs of open and closed loop are also presented ; we realized closed loop controlling system of bbo optical parametric oscillator tuning system, by using american general scanning inc. ' s controller to control bbo crystal ' s rotation, and scaled the output wavelength with charge coupled device
在實驗設計上給出了利用兩塊bbo晶體補償走離效應返回式泵浦非穩腔的實驗設計，設計了開環和閉環兩套控制系統。通過使用美國通用掃描公司的掃描頭控制bbo晶體的轉動，用ccd對bbo - opo輸出波長進行標定，實現了bbo - opo調諧系統的閉環控制，相對波長調諧誤差小於0 . 04 ，並給出了354 . 7nm泵浦的類相位匹配bbo - opo輸出波長隨晶體轉角變化的理論和實驗曲線。
