egd meaning in English

食道、胃、十二指肠镜检查
析出气体检测

We also show that preparation methods , working parameters , substrate orientation , the type and amounts of doped ions , and annealing temperature are all exerting influences over egd . this is why different egd values are reported in literatures
另外我们还讨论了e _ g ~ d值的影响因素，如制备方法、工艺参数、基体取向、掺杂离子种类、掺杂离子数量、退火温度等等，解释了为什么不同文献报道的e _ g ~ d值有所不同。
Tem analysis demonstrates that the film quality is indeed improved as manifested by smoother ? - fesi2 / si interface , more homogeneous film thickness , finer grains , and higher thermal stability . further analysis by photon absorption measurements reveals that the bandgap value egd is not significantly altered . therefore , carbon dosage is favorable for obtaining high - quality ? - fesi2 films
经透射电镜分析可知引入碳离子后硅化物层的微结构向有利于薄膜质量的方向的发展，晶粒得到细化， - fesi _ 2层稳定性提高，因此从微结构角度考虑，引入c离子对于提高- fesi _ 2薄膜的质量是很有益处的。
