  1. This paper deriving the theory work inflection point in the static stage characteristics curve of small measurement range linear dimension measurement. by the way of high pressure and back pressure pneumatic measure and designed the parameter of the mainly and measure spray head, which are the key component in the spray head - baffle pneumatic sensor. the different groups for the main - spray head and the measure spray head, will effect the dynamic and static stage characteristic parameter. the author have done contrast experiment and optimization design to test and verify the theory derivation whereby made the rang of show valve of pneumatic measure system measure range up to 40 u m, the sensitivity up to 100mv / u m, resolution up to 0. 05 p m, the uncertainly of measure is less than 0. o2 u m, satisfaction of requirement of groups the carboy hatch thickness size precise measure of soft shims

    對高壓背壓式氣動測量用於小量程線性尺寸測量的靜態特性曲線的理論工作拐點進行了推導，對氣動測量系統中的噴嘴-擋板型氣動傳感器中的關鍵部件? ?主噴嘴和測量噴嘴的參數進行了理論設計，對主噴嘴和測量噴嘴的不同組合，將影響測量系統靜、動態特性指標的噴嘴參數進行了對比實驗和優化設計，並通過實驗驗證了理論推導，從而使氣動測量系統量程的示值范圍達到40 m ，靈敏度達到100mv m ，解析度達到0 . 05 m ，測量不確定度小於0 . 2 m ，滿足了壓縮機缸蓋軟體墊片厚度尺寸精密測量分組的要求。
