The results have shown that P-RE-USY has good hydrothermal stability owing to the migration of hydroxy rare earth cation from the super cages to the sodalite cages enhanced by phosphorus addition, inhibiting the frame...

结果表明，由于磷促进了稀土离子由超笼向方钠石笼中的迁移，阻止了沸石在水热条件下的脱铝作用，从而改善了P RE USY沸石的水热稳定性；P RE USY沸石酸性分布更集中在中强酸范围，有利于发生氢转移反应，而强酸数量的降低有利于减少焦炭形成，改善了焦炭选择性。

METHODS: The location of 65 consecutive patients with Wharton's duct calculus was analyzed by bimanual examination of the floor of month and bite film of the mandible. Of 65 patients, 57 had the stone removed via intraoral duct incision or sialoendoscopy, 8 by submandibular gland excision. After operation, the shape and size of the calculus were observed and measured.

对连续就诊的65例下颌下腺导管结石患者通过口底双合诊和下颌横断片判断结石的位置，手术取石，其中57例经口内直接切开导管取石或内镜辅助下取石，8例行下颌下腺切除术后取石，观察、测量术后所取结石的形状和大小。

TEM shows that drying by direct heating might result in hard aggregation of the tourmaline powder, while hard aggregation might be avoided by azeotropic distillation. Raman spectroscopy reveals that there are O_H and C_H on the surfaces of the tourmaline powder obtained by azeotropic distillation, which indicates that butoxy is chemically adsorbed on the surfaces of tourmaline particles, but not adsorbed on those formed by direct drying. X_ray powder diffraction shows that the intensity of diffraction peaks decreases after grinding. There is no damage to the tourmaline crystal lattice in the process of direct heating, azeotropic distillation, or ultrafine grinding.

透射电镜分析结果表明，直接加热脱去水或正丁醇会使电气石超细颗粒发生硬团聚，而共沸蒸馏法则可有效防止硬团聚的产生；拉曼光谱结果表明，共沸蒸馏法制备的电气石粉末表面存在O—H和C—H键，说明正丁醇在颗粒表面为化学吸附，而直接干燥法得到的电气石粉末表面则没有；X射线粉晶衍射结果表明，研磨过程降低了粉末衍射峰的强度，但直接加热干燥和共沸蒸馏干燥均未破坏电气石的晶格结构。
