Methods : By using the permeable collagen membrane as a substrate we modified the three dimensional fibroblast culture . After being cultured for 6 weeks the fibroblast cultures were double colored with uranium acetate and lead nitrate and finally observed with electron microscopy .

方法：采用可渗性胶原膜（Celgen○R）作为底物，改进成纤维细胞的三维培养，6周培养后的培养物用 醋酸 铀和硝酸铅双重染色后用电镜进行观察。

The viral particles negatively stained with 1 % uranium acetate observed under transmission microscope appeared to be enveloped or unenveloped because of the envelope being damaged .

病毒粒子经1% 醋酸 铀负染后镜检，病毒粒子分为有囊膜和完全或部分失去囊膜两种。

The relatively regular liver tissue was removed to make ultrathin section after disposal under double staining of uranium acetate and lead citrate and observe epicyte system under transmissive electron microscope .

取相对固定部位的肝组织块，经处理后制成超薄切片经 醋酸 铀-枸椽酸铅双重染色，在透射电镜下观察膜系统。

By this method the Na + ion and the precipitator sodium uranium zinc acetate reacts under the acid conditions to form sodium uranium zinc acetate to determine the Na + contents .

藉在酸性条件下Na~+和沉淀剂醋酸铀 酰锌反应，生成 醋酸 铀酰锌钠来测定Na~+含量。

Study on the extraction of uranium (ⅵ) in ethyl acetate system with DCH-18-C-6

DCH-18-C-6/ 乙酸 乙酯萃取体系萃取分离 铀（Ⅵ）的研究

We found that there is a distinct black particle in the protein cavity through observing the TEM picture of the Fe-Co sample which was stained by the uranium acetate ; this is the Fe-Co nano particle we synthesized .

观察经 乙酸双氧 铀染色后的铁钴样品，发现在蛋白质分子内有一个明显的黑色颗粒，这就是我们合成的铁钴纳米颗粒，说明纳米颗粒是在蛋白质空腔内形成。
