Bdt beckmann differential thermometer
貝克曼差示溫度計 -
It seems the ncz silicon has a higher bdt temperature compared with cz silicon ' s. it is suggested that the elastic effects and the electronic effects of nitrogen doped in silicon made the bdt temperature higher. the observation of fracture surface showed that it was curves at high temperature in brittle fracture, but smooth planes at room temperature
當溫度升高達到硅材料的脆塑轉變時，材料的斷裂強度有個很大的提高，但是首次發現含氮硅單晶卻不明顯，而且摻氮的硅單晶脆塑轉變溫度比普通單晶高，可能是氮的摻入改變了硅材料的內部晶體結構及電子結構。 -
What ' s more, the amount of oxygen precipitates, dislocations in silicon and the orientation of the pressed surface also influence the fracture strength. stress - strain curves were studied at room temperature. in another experiment, brittle - ductile transition ( bdt ) of ncz and cz were studied for first time
常溫下氮硅單晶（ ncz ）及普通硅單晶（ cz ）的斷裂強度研究發現，氮的摻入提高了機械性能，並且不同氧沉澱量、位錯的存在及不同晶向對硅材料機械強度也有較大影響。 -
On the basis of the concepts of divide - and - conquer and rough - fine, dia build a set of algorithm models including two rough classifiers ( i. e. bdt and cmac ) and three fine classifiers ( i. e. clchfpp, cpn - wed, nne - ifm ) which integrate some techniques such as clustering, decision tree, neural networks, fuzzy logic and information fusion etc. and take advantage of them, so dia has a high accuracy and speed theoretically
Dia系統中演算法模型的設計基於「分而治之」和「由粗到精」的模式識別思想，具體構建了兩種粗分器（ bdt和cmac ）及三種精分器（ clc - fpp 、 cpn - wed和nne - ifm ） ，這些分類器的設計綜合了聚類法、決策樹、神經網路、模糊邏輯以及信息融合等技術的應用，並使其優勢互補，因此在理論上具有識別精度高及速度快的優點。
