Determination of Glucose in Serum by Enzyme-Ion Chromatography

利用葡萄糖氧化酶对β-D-葡萄糖催化氧化的高度专一性,催化性能高的优点,催化血清中β-D-葡萄糖被溶液中的溶解氧氧化为D-葡萄糖酸,同时结合离子色谱法快速、灵敏、准确的特点,检测生成的D-葡萄糖酸,并用标准工作曲线法来定量血清中的葡萄糖的含量,建立起酶-离子色谱法检测血清中葡萄糖的新方法.该法线性范围为1.00~90.00mg/L.测得值与采用贝克曼CX3测得值相比,误差为-2%~2%.β-D-Glucose in serum was oxidized by the oxygen dissolved in solution with the catalysis of glucose oxidase based on its high selectivity to glucose. We used the ion chromatography to determine the production, D-glucose acid and then the concentration of glucose in serum could be quantitatively determined through a standard working curve with a linear range of 1.00～90.00 mg/L.A new method has been developed to determine the glucose in serem.福建省重大科技项目资助(2003Y010

Ni-Al-Sn三元系在800和1000℃时的相平衡（英文）

采用电子探针显微分析和X射线衍射分析等方法研究了Ni-Al-Sn三元系在800和1000℃时的相平衡。结果表明:（1） Ni-Al-Sn三元系在800和1000℃时均未发现三元化合物;（2） Ni-Al侧存在Ni Al、Ni3Al、Al3Ni和Al3Ni2 4个化合物,800℃时,Sn在Ni Al和Ni3Al中的固溶度分别为3.1 at%和14.7 at%,在1000℃时分别为3.0 at%和8.0 at%。而Sn在Al3Ni和Al3Ni2中几乎没有固溶度;（3） Ni-Sn侧有Ni3Sn（r）、Ni3Sn（h）和Ni3Sn2（h） 3个化合物。800℃时,Al在Ni3Sn（r）相的固溶度为4.2 at%,1000℃时,Ni3Sn（r）相转变为Ni3Sn（h）相,拥有5.5 at%Al的固溶度。另外,800℃时,Al在Ni3Sn2（h）相中的固溶度为8.4at%,1000℃时为12.1at%;（4）Ni-Al-Sn三元系Al-Sn侧为相互贯通的液相区域,Ni在Al-Sn侧的溶解度约为1 at%。National Natural Science Foundation of China(51771158,51471138)International Science and Technology Cooperation Program of Ministry of Science and Technology of China(2014DFA53040

基于纯金属杨氏模量的实验信息,本研究对纯金属的杨氏模量随温度变化的半经验模型中的参数进行了优化.借鉴相图计算的CAlPHAd(CAlCulATIOn Of PHASE dIAgrAM)方法,构建了多元合金杨氏模量计算的模型.基于二元合金的杨氏模量实验信息,对fE-nI和TA-MO二元系的杨氏模量计算参数进行了优化,计算了合金在不同温度和成分时的杨氏模量,计算结果与实验数据取得了良好的一致性.基于二元合金的优化参数,运用三元合金的计算模型,预测了TAnb-W和TA-nb-MO在不同温度和成分时的杨氏模量.Based on experimental data of Young′s modulus of pure metals,the parameters of the semiempirical model,which describes how the Young′s modulus of pure metals changes with temperature,are assessed.Imitating the CALPHAD method,we propose a calculation model to calculate the Young′s modulus of a multicomponent alloy system.Based on the experimental information of the binary alloy,the parameters of the Young′s modulus in the Fe-Ni and Ta-Mo systems are optimized.The results are consistent with the experimental data.With the parameters assessed in binary systems,the Young′s modulus of the Ta-Nb-W and Ta-Nb-Mo ternary systems changing with temperature and composition are predicted.国家重大科技基础设施项
