Methods paraffin method , semi - thin sectioning , and histochemical method were used 方法石蠟切片法、半薄切片法、組織化學(xué)法。
Ultra thin section 超薄切片
That shape , something like an apple sliced downward through its core , would be constant for a bar magnet 形狀像蘋果的向下穿過它的果核的心形薄切片,對(duì)條形磁鐵來說磁線是恒定不變的。
The most advantage of this method lies in the embedding blocks that are hard enough to be cut into thin sections 這種方法最大的優(yōu)點(diǎn)在于聚合后的包埋塊易于切成超薄切片,幾乎不會(huì)有顫痕產(chǎn)生。
Using semithin sections techniques the histological development of the autograft arabidopsis thaliana ( columbia24 ecotype ) were examined 采用半薄切片技術(shù),對(duì)c24擬南芥自體嫁接組合嫁接體的發(fā)育過程進(jìn)行了組織學(xué)觀察。
Comparative observations were made on the morphology and anatomy of secretory cavities in stems of 14 genera , 23 species and one varieties by paraffin and thin section method 摘要利用石蠟切片和薄切片方法對(duì)蕓香科14屬23種和1變種植物幼莖中分泌囊的分布和結(jié)構(gòu)進(jìn)行了比較研究。
With afm and tem , the inner ultrastructure of murine es cells could be observed . combined with the technique of ultra - thin sections , afm is capable of studying the inner structure of sample 本實(shí)驗(yàn)結(jié)果表明, afm技術(shù)如與超薄切片技術(shù)相結(jié)合,可對(duì)樣品的內(nèi)部結(jié)構(gòu)進(jìn)行研究,而不僅僅是一種表面成像工具。
The infected cells were passaged so that the virus could be isolated . cpe were observed from passage 2 to passage 9 postinfection . the cultured virus supernatants were harvested when cpe were observed in 3 / 4 infected cells 接種后的胚肺細(xì)胞從第二代到第九代均出現(xiàn)細(xì)胞病變,當(dāng)接毒細(xì)胞有3 4出現(xiàn)細(xì)胞病變時(shí),收集培養(yǎng)的細(xì)胞,制作超薄切片進(jìn)行電鏡觀察,發(fā)現(xiàn)了病毒樣粒子。
( 4 ) we use sem to observe fractured morphology of composites , and tem to observe dispersion and particle size of nanoparticles or composited nanoparticles in matrix . we also investigate dispersion property of composited nanoparticles in polymer matrix with the help of microtone ( 4 )采用掃描電鏡( sem )觀察缺口沖擊的斷裂形貌,通過透射電鏡( tem )觀察納米粒子和復(fù)合納米粒子的分散情況和粒徑的大??;通過超薄切片法研究復(fù)合粒子在聚合物基體中的分散性。
