利用第一性原理方法研究CuXSe_2(X=B,Al,Ga,In,Tl)力学性质

在广义梯度近似(GGA)和局域密度近似(LDA)下,采用第一性原理方法研究CuXSe2(X=B,Al,Ga,In,Tl)晶体结构的稳定性和力学性质.分析CuXSe2(X=B,Al,Ga,In,Tl)结构的晶格常数,弹性常数,体积模量,剪切模量,杨氏模量,泊松比,对比各材料的力学性质变换规律.计算结果表明,根据力学稳定判据,在零温零压下,CuXSe2(X=B,Al,Ga,In,Tl)的晶体结构是力学稳定的.经过同主族替换,发现晶格常数越大,体弹性模量就越小.这可以解释为X离子半径逐渐增大,晶格常数逐渐增加,晶体的可压缩性也增加.另外,CuTlSe2的剪切模量最小,不容易发生剪切形变.CuBSe2的杨氏模量最大,其刚度最高.由Pugh经验关系可知CuXSe2(X=B,Al,Ga,In,Tl)均属于韧性材料.     

内蒙古兴和县育龄妇女头发中矿质元素分布及影响因素研究

使用电感耦合等离子体原子发射光谱(ICP-AES)和原子荧光光谱法(AFS)分别对内蒙古自治区兴和县180名农村育龄妇女头发中21种矿物元素(铝,硼,钡,钙,镉,钴,铬,铜,铁,镁,锰,钼,镍,铅,硒,硅,锡,锶,钛,钒和锌)的含量及年龄、生育史及饮食习惯等对其产生的影响进行了研究。结果表明,大多数矿物元素(硼,镉,铬,钴,铜,铁,镁,锰,钼,镍,铅,硒,硅,锡,锶,钛,钒和锌)含量从青年组(18～29岁)到老年组(40～45岁)依次减少,而中年组(30～39岁)的钙,镁,锰、铅的含量最低。生育二胎的妇女钙,镁,锰,钼,镍,铅,锡,锶和锌含量最低,这可能与生育次数的增加有关,相关性分析证实钙,铅和锡与生育史有显著性相关。此外,饮食习惯也会影响头发中矿物质元素的含量。经常食用酸菜会导致锌,铁,铜,锰,锶含量水平较低,但钼,铅和硒含量水平较高。而且,锌和硒含量随肉类摄入频率增加而增加。规律性摄入蔬菜会增加硅的含量。同时,经常食用水果会增加锰,镍和钛的含量水平。因此,该研究为解决不均衡饮食习惯盛行的农村地区生育和妇女健康提供基础数据和有用的信息。

X射线荧光光谱法测定花草茶中22种元素

采用粉末压片法制样,应用X射线荧光光谱法对花草茶中N,Na,Mg,Al,Si,P,S,Cl,K,Ca,Ti,Cr,Mn,Fe,Ni,Cu,Zn,Br,Rb,Sr,Ba,Pb共22种元素进行了分析。讨论了测量条件的选择,对于22种目标元素的分析线,除Ba,Pb采用L线外,其余都选择K_α线,在对Rh靶K_α线的康普顿散射进行测量时,应适当降低管电压,选择合适的管电流。采用经验系数法和3条散射谱线(Rh靶L_α线的瑞利散射、0.1876nm处的散射线、Rh靶K_α线的康普顿散射)作内标进行基体效应校正,并对N,Na,Ca,Ti,Mn,Sr,Ba等部分元素进行了谱线重叠干扰校正。实验结果表明,该方法对N,Na,Mg,Al,Si,P,S,Cl,K,Ca,Ti,Cr,Mn,Fe,Ni,Cu,Zn,Br,Rb,Sr,Ba,Pb各目标元素的检出限较低,且准确度较好,精密度较高。采用该方法对花草茶中元素的种类和含量信息进行分析发现,花草茶元素组成较为丰富,不同种类花草茶元素种类和含量有差异,且同一种类不同来源花草茶略有差异,但元素组成含量特征大体相似。综上可知,该方法操作简单,能够实现花草茶的低成本、快速、准确、多元素测定。
