(ii) The white sample was divided intofour parts and separately was observed bySEM (Leo5420, 1020 keV); by TEM(H-7100, 120 keV; JEM-4000, 400 keV)and by HRTEM （2）白色的样品被分成四部分，并用扫描电镜（SEM， Leo5420，10 20keV），透射电镜（(H-7100, 120 keV; JEM-4000, 400 keV)以及高分辨率透射电镜（HRTEM）单独进行了观察。The composition of theproduct was analyzed by energy dispersiveX-ray (EDX, JEM-2010)产品的组分用能量分散X射线法（EDX，JEM-2010）进行了分析。 Luminescence experiments were carried out by exposingthe SiO2 nanowires to X-ray irradiation using a Philips set to deliver a dose of 20 Gy·min− 发光实验通过将SiO2纳米线暴露于X射线辐射下进行，X射线辐射采用Philips公司的设备提供20 Gy·min−1的剂量The 人工翻译，请放心采纳。luminescence emission of the sample was measured using a high-sensitivity multiplexed systemwith F/2 optics 样品的发光发射用一台高灵敏度的、带有所研制的F/2光学元件的复用系统进行测量。 Experiments were conducted at low (25240 K, heating rate 6K·min−1) and high (293673 K, heating rate 50 K·min−1) 实验在低温（25240 K, 加热速率 6K·min−12）和高温(293673 K, 加热速率 50 K·min−1)下进行。 Results and discussion 结果和讨论。SEM ( 2(a)) image reveals the presence of white product on TiSi Under higher resolution,the white product consists of large quantities of wire-like materials and these wires arewinding, exhibiting smooth surface and uniform diameter ( 4090 nm)扫描电镜图像揭示了在TiSi薄膜上存在白色产物。在较高分辨率下，白色产物由大量线状的材料构成，这些线是缠绕的，呈现出光滑的表面和均匀的直径（4090 nm) Further HRTEM examination shows that the nanowires are amorphous ( 2(c)) and EDX analyses indicate that theyconsist solely of silicon and oxygen ( 2(d)) 进一步的HRTEM检验表明，这些纳米线是无定形的（图2（c)），而EDX分析表明，它们仅由硅和氧组成（图2（d)）。Computer analyses exhibit that the SiO ratio Therefore, they are very long amorphous SiO2 计算机分析表明，硅、氧的比率是1：因此它们是很长的无定形SiO2纳米线。
