请各位高手帮忙翻译一段话，不甚感激！ 图1a为没有回流得到的Sb2S3前躯体的XRD谱图，由图可以看出前躯体的衍射峰比较弱，峰的强度较低，表明前躯体的结晶度低、晶体生长不完整，但其衍射峰都可以归属到正交晶相的Sb2S3(JCPDS: 42-1393)，无杂质峰，说明此时反应物已完全反应并生成了Sb2S3；图1b为前驱体回流15 h后所得到的硫化锑纳米棒的XRD谱图，由图可以看出，衍射峰峰形尖锐，衍射强度较高，表明样品结晶良好，晶体生长完整。对其进行晶面指标化，所有衍射峰也和正交晶相的Sb2S3相吻合 (JCPDS: 42-1393)，没有其它杂质峰，说明产品纯度高。经计算，其晶胞参数为a=1.124 nm, b=1.138 nm, c=0.384 nm，该值与标准卡片基本一致。由此可以看出，在进行回流反应前即已生成了Sb2S3。 |

| Figure 1a shows the XRD pattern of Sb2S3 precursor without circumfluence, one can see that the diffraction peaks of precursor are relatively weak, the intensities of peaks are much lower, indicating that the crystallization of the precursor is weak, and the crystal growth is not complete. However, the diffraction peaks of the precursor can be attributed to the orthorhombic phase Sb2S3 (JCPDS: 42-1393), without any impurity peaks, demonstrating that at this moment, the reactants have been completed reacted to generate Sb2S3; Figure 1b displays the XRD patterns of antimony sulfide nanorods after 15 h precursor circumfluence. It can be seen from the figure that the diffraction peaks is sharp, and their intensities are high, indicating that the sample is well crystallized. After indexed of the crystal plane, all the diffraction peaks are consistent with the orthorhombic phase Sb2S3 (JCPDS: 42-1393), and not any impurity peaks are observed, indicating the production is of high purity. After calculation, the lattice parameters are a = 1.124 nm, b = 1.138 nm, c = 0.384 nm, and the value matches well with the standard card. Then, it can be deduced that Sb2S3 had been generated before the circumfluence reaction. |

| As shown in Figure 1a ,the XRD spectra of Sb2S3 precursor gained without circumfluence,it can be seen that the diffraction peaks of precursor are relatively weak , and the peaks intensity are lower, indicating that the crystallization degree of the precursor is low,and the crystal growth is not complete.However, the diffraction peaks can be attributed to the orthorhombic phase Sb2S3 (JCPDS: 42-1393), without impurity peaks, indicating at this time Sb2S3 has been generated from complete response of reactants; Figure 1b is a XRD spectra of antimony sulfide nanorods after a 15 h precursor circumfluence.From Figure 1b ,it can be seen that the diffraction peaks-shaped is sharp, and the diffraction strength is higher, indicating a good crystal sample, and a integrity crystal growth . Form the index to crystal face , all the diffraction peaks are coincide with the orthorhombic phase Sb2S3 (JCPDS: 42-1393) without impurity peaks, indicating a high purity of production. After calculation, the lattice parameters are a = 1.124 nm, b = 1.138 nm, c = 0.384 nm, and the value is basically consistent with the standard card. It can be seen that Sb2S3 had been generated before the circumfluence reaction. |

| Figure 1a for not returning the body get Sb2S3 former XRD spectra can be seen from the figure before the body is relatively weak diffraction peaks, peak intensity lower, indicating that the crystallization of the former body is low, crystal growth is not complete, but the diffraction peak can be attributed to the orthorhombic phase Sb2S3 (JCPDS: 42-1393), no impurity peaks, indicating a complete response at this time of reactants and have been generated Sb2S3; Figure 1b as a precursor reflux obtained 15 h after antimony sulfide nano - XRD spectra of rods from the map can be seen, the diffraction Peaks-shaped sharp, diffraction strength is higher, indicating a good crystal sample, crystal growth and integrity. Index crystal face of them, all the diffraction peaks have and the orthorhombic phase Sb2S3 coincide (JCPDS: 42-1393), no other impurity peak, indicating high purity. After calculation, the lattice parameters a = 1.124 nm, b = 1.138 nm, c = 0.384 nm, the value is basically consistent with the standard card. It can be seen that reaction before making back i.e. generated Sb2S3. |
