Routine and research polarizing microscope 日常工作和科研用偏光顯微鏡
New student teaching polarizing microscope 新型教學偏光顯微鏡
Standard test method for photoelastic determination of residual stress in a transparent glass matrix using a polarizing microscope and optical retardation compensation procedures 用偏光顯微鏡和光學延遲補償方法在透明玻璃基質(zhì)中測定光彈性殘余應力的標準試驗方法
Polarizing microscope a light microscope that uses polarized light to illuminate the specimen . the orientation of molecules in certain crystalline substances affects the transmission of polarized light 偏振光顯微鏡:指利用偏振光照射樣品的一種光學顯微鏡。在某些結晶體中,分子的方向影響偏振光的傳播。
The surface structures of the pink freshwater pearls from jiangsu - zhejiang region and the white seawater pearls from guangdong province are studied by using polarizing microscope and scanning electron microscope ( sem ) 以產(chǎn)于江浙地區(qū)的粉色淡水珍珠和產(chǎn)于廣東省的白色海水珍珠為研究對象,采用偏光顯微鏡和掃描電鏡測試方法對其表面結構進行了觀察。
In order to find out the mechanism of bone growth and biodegradation of this kind materials animal experiment was adopted in this paper , by use of sem , epma and polarizing microscope it discussed the transformation of porous bioceramic after implanted in rabbit ' s femur . in this experiment we got some important findingsfirstly , after implanted the material began to degrade indeed 利用掃描電鏡、電子探針、 x光片以及甲苯胺藍和he染色等組織學觀測手段,本文探討了- tcp多孔生物陶瓷在植入骨內(nèi)后結構形態(tài)與組成的變化,深入分析了- tcp多孔生物陶瓷的降解機理和晶體轉(zhuǎn)變過程。
Side chain polyurethanes with azo group are characterized and confirmed by ftir , uv - vis , dsc , vpo , z - scan , polarize microscope . the results show that the end - group and the flexibility of main chain affects the growing up of liquid crystalline phase greatly . because the determinable way of detection is defective , it was not founded the liquid crystalline behavior obviously contributes to the non1inear optical thection 最后,在分析討論實驗結果的基礎上,指出側鏈型聚氨酯液晶中側鏈介晶基元的末端基團及主鏈的柔性對其液晶態(tài)的形成有重要影響;由于檢測手段的不齊備,未能觀察到熔致型聚氨酯液晶的液晶行為對其非線性光學效應的貢獻作用。
This has an important meaning to the industrial manufacture . dsc , waxd and polarizing microscope with hot stage experiments were performed to describe what led the ssp rate acceleration of pet / mmt . it was shown that montmorillonite acted as a very good nucleating agent in pet crystallization process , which results in the lower crystallinity , more small microlites , and more surfaces of microlites 為研究pet mmt固相縮聚效率提高的原因,通過熱臺偏光顯微鏡、 dsc 、 x -射線衍射等手段對樣品的結晶進行觀察與分析研究,結果表明蒙脫土對pet的結晶有明顯的成核作用,使其晶核生成速率迅速提高,晶核數(shù)量明顯增多,從而使整個結晶過程的時間變短,同時形成了更多結構不完善的微晶體。
