求大神帮忙翻译一段话，做实验用。

| The typical FESEM images of Tm3+ (figures 5(a) and (b)), Tb3+ (figures 5(c) and (d)) and (figures 5(e) and (f)) Eu3+:Y2O3 are shown in figures 5(a)–(f). Figures 5(a), (c), and (e) show the low magnification images and figures 5(b), (d), and (f) show the high magnification images of nanotubes, indicating the presence of tubular morphology after calcination. These results suggested that when the rare earth ion doped Y(OH)3 nanotubes were calcined at 500 ◦C in air for 4 h, rare earth ion doped Y2O3 nanotubes were obtained. The diameter of Tm3+, Tb3+, and Eu3+:Y2O3 nanotubes are about 80–120 nm (outer diameter), 50–100 nm (inner diameter), and length about 1–5 μm. Figure S4 (available at stacks.iop.org/Nano/20/305302) shows the few nanotubes with ruptured tubular morphology after calcination at 800 ◦C for 4 h, indicating that the tubular morphology can be retained even..after calcinations at 800 ◦C. |

| Tm3+ (图5(a) and (b)), Tb3+ (图5(c) and (d)) and Eu3+:Y2O3(图 5(e) and (f))的典型FESEM照片如图5(a)–(f)所示。图5(a), (c), and (e)为纳米管的低放大倍数照片，图5(b), (d), and (f)为高放大倍数图片，都表明焙烧之后管状形貌的出现。这些结果表示当在空气中500摄氏度下对掺入了稀土元素的Y(OH)3纳米管进行焙烧4小时，将得到掺杂有稀土元素的Y2O3纳米管。Tm3+, Tb3+, and Eu3+:Y2O3纳米管的直径大概在80–120 nm (外径), 50–100 nm (内径), 长约 1–5 μm。图S4(在stacks.iop.org/Nano/20/305302可获取)展示了一些在800摄氏度下焙烧4小时得到的破裂管状纳米管，这表明管状形态在焙烧温度达到800摄氏度下仍能保持。 |
