| 1 | Study on the Synthesis and Adsorption Properties of KH-560 Modified PalygorskiteSupported β-Cyclodextrin显示文摘1 Results Palygorskite (PGS) is a chain-layer magnesium-aluminum silicate mineral. Because of its developed interior channels and large specific surface area, and thus considerable adsorption capacity, it has been studied for the application as one of environmental mineral adsorbents[1-3]. Cyclodextrins (CD) possess a hydrophilic exterior and a hydrophobic interior into which a variety of hydrophobic organic molecules maybe introduced. The CD molecule not only affects a hydrophilic cavity on the nanomet... | D.M.ZHU L.YAN X.L.SHI Y.CHANG | 2007 | 复旦学报(自然科学版)2007，46，5： | 0 |
| 2 | Mechanical properties of 65Mn chiral structure with three ligaments显示文摘Chiral honeycomb structures have been developed in recent years, showing excellent mechanical properties, including in-plane deformation and out-of-plane bearing and vibration isolation. In this study, the 65Mn chiral structure with three ligaments was modeled and analyzed using the finite element (FE) method. The effects of the dimensionless ligament length and dimensionless ligament thickness on the in-plane equivalent elastic modulus, equivalent Poisson's ratio, and out-of-plane shear modulus were studied. The numerical results indicate that increase of the dimensionless ligament length leads to decrease of the equivalent elastic modulus and increase of the equivalePoisson's ratio, whereas the out-of-plane equivalent shear modulus decreases. The results also indicate that increase of the dimensionless ligament thickness leads to in crease of the equivalent elastic modulus, whereas the equivalent Poisson's ratio remains nearly unchanged and the out-of-plane equivalent shear modulus shows a linear in crease. The numerical results are verified by comparis on with published experime ntal data. These results will provide a reference for the application of chiral structures with three ligaments in the aerospace field. | X.W.Su D.M.Zhu C.Zheng M.M.Tomovic | 2019 | Acta Mechanica Sinica2019，35，1： | 0 |
| 3 | THE EFFECT OF MELTING TEMPERATURE ON THE PROPERTIES OF PbBr _2-PbCl_2-P_2O_5 GLASSES显示文摘A series of PbBr 2 PbCl 2 P 2O 5 glasses have been prepared and characterized to research the effect of melting temperature on the properties of glasses. The glass forming regions have been explored and the stability of the glasses against crystallization studied. The density, characteristic temperatures, chemical analysis compositions, and infrared absorption spectra of the glasses were measured. Results show that the PbBr 2 PbCl 2 P 2O 5 ternary system melted at 530~540℃ has a broader glass forming region which extended to the side of PbBr2 than that melted at 450~470℃. The glass transition temperature is more than 200℃ and the density is more than 5 5 g·cm 3 . Both the chemical analysis composition and the infrared absorption spectra of some glasses melted at 530~540℃ show that the decomposition of NH 4H 2PO 4 is more complete than that of glasses melted at 450~470℃. | H.S.Zhao,W.C.Zhou, D.L.Zhao and D.M.Zhu State Key Laboratory of Solidification Processing, Northwestern Polytechnical University, Xi’an 710072,China | 1999 | Acta Metallurgica Sinica(English Letters)1999，12，5： | 0 |
