By changing the negative bias current density, gaseous ratio and total pressure, nanocrystalline diamond film is prepared by ion - assisted bombardment method at the substrate temperature of 700 ? 00 ? and mixture gaseous of ch4 and h2 the effect of growth parameters on the diamond film is studied. the diamond film presents very low compressive stress and excellent field emission character
採用離子輔助轟擊法，以ch _ 4 、 h _ 2為源氣，襯底溫度為700 900 ，通過改變襯底負偏壓、 h _ 2和ch _ 4氣體比例以及工作氣壓，制備出納米金剛石薄膜，並對工藝參數對金剛石薄膜沉積的影響進行了研究。 -
Total tissue content, information coming from majority of the current in vivo studies, is therefore a poor index of extracellular concentration. objectives l. to examine how hypoxia affect hippocampal transmitter release ; 2. to attempt to obtain information on the extracellular concentrations of transmitters releasing from hypoxic hippocampus ; 3. to assess the importance of extracellular calcium ion in endogenous release from hippocampus when exposed to hypoxia ; 4. to explore whether ginkgolide b affect the release of transmitters from hypoxic hippocampal slices, providing an direct evidence of its neuroprotective effects
目的1進一步探討低氧對海馬內源性神經遞質釋放的影響； 2觀察低氧時誨馬神經元細胞外液中神經遞質含量的變化； 3評價細胞外液中ca ~ （ 2 + ）在海馬神經元內源性遞質釋放中的作用； 4研究ginkgolideb對低氧時海馬神經遞質釋放的影響，為其是否具有直接的神經保護作用提供實驗依據。
