Morphology of resin retanning agent with different structure in the leather - scanning electronic microscopy study 不同結(jié)構(gòu)的樹脂復(fù)鞣劑在皮革中形態(tài)的電鏡研究
Two different ancient pottery coatings have been analyzed by microzone - raman spectrum and sem - eds ( scanning electronic microscopy - energy dispersive spectrum ) 摘要利用微區(qū)拉曼光譜與掃描電鏡配置的電子探針等技術(shù),分析了兩塊陶器樣品的陶衣。
Film microstructure is investigated by scanning electronic microscopy ( sem ) . the micrographs showed that glass fiber distributed in epoxy resin with good dispersity , and interweaved with each other homogeneously 并利用掃描電子顯微鏡( sem )對(duì)基底材料進(jìn)行了觀察,發(fā)現(xiàn)玻璃纖維能夠在環(huán)氧樹脂基體中形成均勻的分散,并交織成不規(guī)則的網(wǎng)狀結(jié)構(gòu)。
It also showed good cell affinity to the modified pdl - la scaffold investigated by scanning electronic microscopy ( sem ) and confocal laser scanning microscopy ( clsm ) , comparing with the unmodified pdl - la scaffold 掃描電鏡和激光共聚焦顯微鏡的測(cè)試結(jié)果顯示了軟骨細(xì)胞在原浙江大學(xué)博士學(xué)位論文( 2003 )位自修飾的聚乳酸三維支架內(nèi)部良好的粘附與生長(zhǎng)情況。
Firstly , the tio2 thin films are deposited by dc reactive magnetron sputtering apparatus , and characterlized by n & k analyzer1200 , x - ray diffraction spectroscopy ( xrd ) , scanning electronic microscopy ( sem ) , alpha - step500 . and it was analyzed that the effect on performance and structure of films with the change of argon flow , total gas pressure , the substrate - to - target distance and temperature 第一、應(yīng)用穩(wěn)定的直流磁控濺射設(shè)備制備tio2減反射薄膜并通過(guò)n & kanalyzer1200薄膜光學(xué)分析儀、 x射線衍射分析( xrd ) 、掃描電子顯微鏡( sem ) 、 alpha - step500型臺(tái)階儀等儀器對(duì)薄膜進(jìn)行表征,分析氧分壓、總氣壓、工作溫度、靶基距等制備工藝參數(shù)對(duì)薄膜性能結(jié)構(gòu)的影響。
