几种石蒜属花卉观赏性状的灰色评价

以灰色关联度对14种石蒜属花卉的观赏性状进行了评价．结果表明石蒜(Lycoris radiata)的加权关联度Ri为最大(0．713 888)，即观赏效果最好，这与实际运用效果相符；其次是安徽石蒜(L．anhuiensis)，Ri=0．708 429；排在第三位的是长筒石蒜(L．longituba)，Ri=0.703032．其他由大到小次序为夏水仙(L.squamigera)、玫瑰石蒜(L．rosea)、陕西石蒜(L．shaanxiensis)、乳白石蒜(L．albiflora)、短蕊石蒜(L．caldwellii)、麦杆黄石蒜(L．straminea)、肉红石蒜(L．incornata)、中国石蒜(L．chinensis)、换锦花(L．sprengeri)、忽地笑(L．aurea)、江苏石蒜(L．houdyshelii)．从灰色关联度分析结果看，花形整齐、奇特(雄蕊长于花被片，花被片强烈皱缩反卷)，花色稀有和秋冬出叶的，灰色关联度大,14种石蒜均适合作地被，但以秋冬出叶、花葶较矮的种更为适宜，如石蒜、玫瑰石蒜、麦杆黄石蒜、江苏石蒜等。

酸雨腐蚀对大理岩单轴压缩特性的影响

采用室内模拟试验研究酸雨腐蚀对大理岩单轴压缩特性的影响.将大理岩岩样浸泡在封闭的模拟酸雨溶液中,在浸泡时间和温度相同的条件下,改变酸雨溶液的pH;在pH相同的条件下,改变酸雨溶液的温度.通过测定不同时间的酸雨溶液电导率、反应后浸泡溶液的钙离子浓度,分析pH和温度变化对大理岩与酸雨溶液之间化学反应的影响.将浸泡后的大理岩岩样进行单轴压缩试验,分析模拟酸雨对大理岩单轴抗压强度和破坏方式的影响.试验结果表明:在酸雨溶液中浸泡后,大理岩破坏时的脆性程度减弱;室温时,随着浸泡溶液的pH降低,大理岩和酸雨溶液反应更加充分,大理岩单轴抗压强度降低;但当温度为80℃时,大理岩单轴抗压强度随着pH的降低反而明显增大;随着酸雨溶液温度的增加,化学反应速度加快,反应达到稳定的时间缩短,短期内单轴抗压强度比室温时明显降低.     

Determination of discontinuities in marble blocks via a nondestructive ultrasonic technique

Miners working in the marble industry have always been interested in identifying structural weaknesses in marble blocks before they are transported to marble processing plants. To achieve this difficult task, several simple methods have been developed among miners but observation-based methods do not consistently provide satisfactory results. A nondestructive method developed for testing concrete could be used for this purpose. In this study, this simple method based on differences in ultrasonic wave propagation in different materials was presented, and the test results performed both in the laboratory and a marble quarry were discussed.     

Inhibition of acid mine drainage and immobilization of heavy metals from copper flotation tailings using a marble cutting waste

Acid mine drainage (AMD) with high concentrations of sulfates and metals is generated by the oxidation of sulfide bearing wastes. CaCO₃-rich marble cutting waste is a residual material produced by the cutting and polishing of marble stone. In this study, the feasibility of using the marble cutting waste as an acid-neutralizing agent to inhibit AMD and immobilize heavy metals from copper flotation tailings (sulfide- bearing wastes) was investigated. Continuous-stirring shake-flask tests were conducted for 40 d, and the pH value, sulfate content, and dissolved metal content of the leachate were analyzed every 10 d to determine the effectiveness of the marble cutting waste as an acid neutralizer. For comparison, CaCO₃ was also used as a neutralizing agent. The average pH value of the leachate was 2.1 at the beginning of the experiment (t = 0). In the experiment employing the marble cutting waste, the pH value of the leachate changed from 6.5 to 7.8, and the sulfate and iron concentrations decreased from 4558 to 838 mg/L and from 536 to 0.01 mg/L, respectively, after 40 d. The marble cutting waste also removed more than 80wt% of heavy metals (Cd, Cr, Cu, Ni, Pb, and Zn) from AMD generated by copper flotation tailings.
