At the same time, it is suggested that how to load samples is still an important issue in nir diffuse reflectance analysis
由於裝樣誤差在模型整體誤差中所佔比重較大,所以嚴格控制裝樣在漫反射近紅外分析中仍是一個值得注意的問題。Consequencely, the analysis and assessment system of the operating state of the concrete dam was developed under the ansys development environment, and the back - analysis and the prediction of the parameters of the dam system have been done according to the operating observed data. the research work involves several aspects as follows : 1 ) a back - analysis model including the prior information and a predictive model of nonlinear time series were established ; 2 ) the analysis and assessment system of the operating state of the concrete dam was developed under the ansys development environment, in which the analysis module of the loading effects, the back - analysis module, the forecasting module of the physical parameters and the assessment module of the operating state were contained ; 3 ) according to the operating observed data, the operating state of the dam was assessed and predicted with the analysis system of the operating state, the results suggested that the dam is in basically normal operation at present
具體工作有以下幾方面: 1 )收集整理漫灣水電站大壩運行監測資料,並對其進行了系統分析,從觀測資料本身直觀的分析了大壩的運行狀況; 2 )總結位移反分析的理論及方法,建立了考慮先驗信息多介質位移反分析模型,基於神經網路非線性映射功能,建立了神經網路時間序列預測模型; 3 )以ansys軟體為平臺,開發了漫灣水電站砼重力壩運行狀態評價模塊,結合荷載效應分析、參數反演分析、參數預測分析三個模塊組成漫灣水電站砼重力壩運行狀態分析系統;實現了對漫灣水電站運行狀態的動態「反演-預測」分析; 4 )利用漫灣水電站砼重力壩運行狀態分析系統,在漫灣大壩實測資料分析、大壩砼特性參數反分析、大壩砼彈性模量衰變規律及預測分析的基礎上,系統的分析並預測了大壩運行狀態。This paper realized the aumotic detection of assembling angle position of intravenous needles by image technology. during the study, this paper designed light with a piece of white paper and halogen lamp to take the images of intravenous needles ; analyzed in detail hu moment invariants of digital image, amended i7 and chose i1 ~ i5 and amended i7 as eigenvector groups ; put forward a method of angle recognition based hu moment invariants ; the methods above were employed by vc + +, and a prototype system of software is compiled
在輸液針的角度識別的研究過程中,用鹵素燈和白紙構建了一個漫反射體作為輸液針圖像獲取理想的光源;分析了矩不變量的不變性,修正了矩不變量i _ 7 ,選用了i _ 1 i _ 5和修正後的i _ 7來提取輸液針圖像的特徵;針對輸液針圖像的特點,提出了一種基於矩不變量的角度識別方法;在開發平臺vc + + 6 . 0上編寫了一個輸液針角度識別的軟體原型系統,實現了其演算法。Standard material has a diffuse shading model that does an excellent job of rendering solid, nonreflective objects such as plastic, ceramic, and so on
標準材質有一種漫反射著色模式,這對于渲染固體、以及非反射對象,例如塑料、陶瓷等等的效果是極好的。分享友人
