| 7 | Primary experimental studies on mid—infrared FEL irradiation on dental substances at BFEL显示文摘A free electron laser (FEL) with its characteristics of wide wavelength tunability,ultrashort pulse time structure,and high peak power density is predominantly superior to all other conventional lasers in applications.Several experimental studies on mid-infrared FEL irradiation on dental enamel and dentine were performed at the Beijing FEL. EXperimental aims were to investigate changes in the hardness,ratios of P to Ca and Cs before and after irradiation on samples with a charateristic absorption wavelength of 9.66μm,in the colors of these sample surfaces after irradiation with different wavelengths around the peak wavelength.The time dependence of temperature of the dentine sample was measured with its ps pulse effects compared to that with a continuous CO2 laser.FTIR absorption spectra in the range of 2.5-15.4μm for samples of these hard dental substances and pure hydroxyapatite were first examined to decid their chemical components and absorption maximums.Primary experimental resulte will be presented.2001 Elsevier Science B.V.All rights reserved. | ZhuJunbiao LiYonggui LiuNianqing ZhangGuoqing WangMinkai WuGan | 2001 | Beijing Synchrotron Radiation Facility2001，，2： | 0 |
| 8 | A preliminary study of the weathering mechanism of fossilized Cretaceous Hamipterus bones显示文摘The discovery of Hamipterus tianshanensis had important scientific significance because three-dimensional preserved fossils can provide unique information about the reproduction,development,and evolution of pterosaurs.However,the pterosaur fossils exhibited violent weathering,including noticeable cracking and spalling,since the preservation environment changed dramatically after excavation,which severely influenced the preservation of these fossils and the scientific research conducted on them.To determine the weathering mechanism of these fossil bones,the samples were analyzed using X-ray fluorescence(XRF),Fourier transform infrared spectroscopy(FTIR),X-ray diffraction(XRD),scanning electron microscopy and energy dispersive spectrometry(SEM-EDS).The results indicate that calcite is the main mineral in the hollow bones,but it is mixed with a small amount of other minerals,such as quartz,feldspar,and other debris particles.Moreover,the main component of the pterosaur bones is hydroxyapatite,and carbonate has substituted for some of the phosphate(B-type carbonated apatite)in the fossil bones.A small amount of calcite and manganese oxides has precipitated in the vascular canals.The phosphate crystallinity index(PCI)is 4.17.These results indicate that the fossils have undergone severe diagenesis.Apart from these alterations,the fossil bones have high contents of anions and cations such as Cl^(-),NO_(3)^(-),SO_(4)^(2-),Na^(+),and Ca^(2+),and the total content of soluble salts is 35584.41μg g^(-1).Based on these results,it is inferred that the weathering mechanism of the fossil bones is as follows.First,the fragile hollow bones cracked easily because of the enormous thermal stress caused by the dramatic temperature changes in the Gobi Desert and the differences in the thermal expansion coefficients(TEC)of the surrounding rocks,the fossil bones,and the different fillers.Second,a large amount of stress is generated by salt crystallization when the temperature and humidity change,and the pterosaur fossils will be damaged when the crystallization pressure exceeds the tensile strength of the fossils.These results suggest that the preservation of pterosaur fossils requires suitable desalination and consolidation conditions.Moreover,they should be preserved in a constant temperature and humidity environment. | Ying LI Wugan LUO Yimin YANG Shunxing JIANG Xiaolin WANG | 2021 | Science China Earth Sciences2021，64，3： | 0 |
