【正文】 catalyst(催化劑 ) for the growth of nanoZnO arrays are less reported. The paper has enriched ZnO nanomaterials synthesizing methods, and the growth control mechanism was discussed. ? 摘 要 : 利用低壓金屬有機(jī)化學(xué)氣相沉積（ LPM0cVD）技術(shù)，在表面含有 ZnO顆粒作為催化劑的 si（ 111）襯底上制備了 ZnO納米柱陣列。采用 X射線衍射（ XRD）、喇曼光譜 (Raman)、掃描電子顯微鏡（ SEM）、光致發(fā)光（ PL）譜分析了樣品的晶體結(jié)構(gòu)質(zhì)量、表面性質(zhì)和光學(xué)性質(zhì)。結(jié)果表明，生長(zhǎng)出來(lái)的納米 ZnO具有較好的軸擇優(yōu)取向性。發(fā)現(xiàn)氧分壓對(duì) ZnO納米柱的生長(zhǎng)有重要影響：當(dāng)氧分壓較低時(shí)，生長(zhǎng)基于 VLS機(jī)制；當(dāng)氧分壓較高時(shí)，生長(zhǎng)基于 VS機(jī)制；通過(guò)對(duì) N2O流量的控制可實(shí)現(xiàn)對(duì) ZnO納米材料的可控生長(zhǎng) . 使用范疇 ? 研究或試驗(yàn)報(bào)告 ? 研究論文及專題論文 第二部分 摘要的撰寫要求 Writing Principles 行文原則 Principle . ?

The onset of chronic leukemia is frequently so insidious that it is accidently discovered when a blood count is obtained for other reasons or when the patient reports to his physician that he has noted a few enlarged lymph notes or felt, while bathing, a firm left quadrant abdominal mass. ? Change the long one into short: The onset of chronic leukemia is frequently so insidious. it is accidently found when a blood count is obtained for other reasons. Sometimes the patient’s own discovery of a few enlarged lymph notes and firm left quadrant abdominal mass may lead to its diagnosis. ? Get rid of the unnecessary words in a sentence. .
