石结构抗震可靠度的分析与应用

在文献［１］的基础上进一步探讨了石结构体系抗震动力反应分析的计算方法，给出了场地地震条件下结构在使用期间内抗震可靠度的应用实例。定量分析的结果表明，严格地控制结构高度、层数和砂浆强度等级等指标，是提高多层石结构抗震能力的有效措施。     

Raman Spectroscopy of Garnet—group Minerals

The Raman spectra of the natural end members of the garnet-group minerals,which include pyrope, almandine and spessarite of Fe-Al garnet series and grossularite ,andradite and uvarovite of Ca-Fe garnet series, have been strdied.Measured Raman spectra of these minerals are reasonably and qualitatively assigned to the internal modes, translational and rotatory modes of SiO4 tetrahedra, as well as the translational motion of bivalent cations in the X site.The stretch and rotatory A1g modes for the Fe-Al garnet series show obvious Raman shifts as compared with those for the Ca-Fe garnet series ,owing to the cations residing in the Xsite connected with SiO4 tetrahedra by sharing the two edges.The Raman shifts of all members within either of the series are attributed mainly to the properties of cations in the X site for the Fe-Al garnet series andin the Y site for the Ca-Fe garnet series.     

我国饮用天然矿泉水开发现状及主要问题

本文主题为饮用天然矿泉水。碳酸矿泉水，硅酸矿泉水，锶矿泉水是我国饮用天然矿泉水的主要类型，约占全国已发现矿泉水的９５％。矿泉水主要生产国及消费国都在欧洲。亚洲的日本、韩国等国的矿泉水的产量也在大幅度增长。而我国矿泉水产量近年也以较大的速度增长，但只有名牌产品才有可观的经济效益。
