pressure excursion 中文意思是什麼
pressure excursion
解釋
壓力偏差-
There are better performances in the films prepared by ba2ca2cu3ox target than by ba2cacu2ox target. the single - phase tl2ba2cacu2o8 hts thin film was obtained with a tc0 of 107k at the optimal tl2o partial pressure and thallination temperature 750. on excursion from the optimal conditions, there exist some impurities in the resultant films resulting in a reduction in tc0 and surface quality with change in the microstructure morphology
研究結果表明，採用成分為ba2ca2cu3ox的靶材制備的薄膜性能要優于成分為ba2cacu2ox的靶材；使用組成式為tl1 . 9ba2ca2cu3oy的鉈片做鉈源時，形成的tl2o分壓達到最佳值；在最佳tl2o分壓和最佳鉈化溫度750的條件下，制備出了純相完全c軸取向的tl2ba2cacu2o8高溫超導薄膜，其tc0高達107k ，膜面均勻平整光滑，呈圓片狀組織；偏離最佳制備工藝參數的條件下，制得的薄膜中都含有一定量的雜相，雜相的生成使得tc0值下降，薄膜表面質量下降，薄膜組織形貌發生變化。 -
The traditional level measuring methods can n ' t meet our demand because the subjective investigated is in such a poor systemic condition that the temperature is a little high and there ' s so many mill dust and steam there. in this article we perform systemic discuss and research against the dynamic level measuring method under special working condition on the basis of analyzing kinds of level measuring technique in and abroad. first we establish the pressure distribution mathematic model in storage bin and then deduce the mathematic relation between level height and the uniform stress on the bottom of the bin and designed a resistance compressive stress sensor used for the special condition and put forward a resoivement according to its zero excursion existing in practical use
由於本研究系統被測對象環境溫度較高且潮濕，同時料倉中有大量粉塵及蒸汽，因此傳統的料位檢測方法不能滿足本測試要求。本文在分析國內外各種物位檢測技術的基礎上，針對特殊工況下動態物料高度的檢測進行了系統的探討與研究。首先建立了料倉中的壓力分佈數學模型，推導出料位高度與倉底均布壓力間的數學關系式，並據此設計了中溫電阻應變式壓力傳感器，同時對它在實際應用中存在的零點漂移等問題提出了改進措施，提高了傳感器性能，解決了上述特殊工況下動態物料檢測的技術難題。 -
Through over ten years ‘ development and consistent improvement, this kind of product can make temperature excursion of high temperature melt pressure transducers reduced greatly and can be used in strong acid and alkaline environment, since a new film invented independently has been equipped from march 1998
該產品通過十多年的研製並不斷的改進，從1998年3月開始採用自主研製的新型膜片，使高溫溶體壓力傳感器的溫漂大幅下降，並可在強酸堿環境中使用。
