A novel electrochemical procedure for the synthesis of ethyl carbanilate from aniline and carbon dioxide was developed via the selective cathodic reduction of carbon dioxide in CO2-saturated DMF solution containing 0. 1 mol/L TEABr at room temperature, followed by the addition of Eft as an alkylating agent. The synthesis was carried outun der mild[p（CO2） = 1.0×10^5 Pa, t =20 ℃ ] and safe conditions. Influences of the nature of the electrodes, the current densities, the passed charges during electrolysis, temperatures, and supporting electrolytes on the yield of ethyl carbanilate were studied to optimize the electrolytic conditions. The selectivity of ethyl carbanilate is 100%.

[N-（Propionic acid）] terephthalal acyl dihydrazone（H4L） was synthesized and characterized by element analysis, IR, 1H NMR and MS. The theoretical studies on H4L were carried out at HF/6-31＋G（d） and B3LYP/ 6-3 I＋G（oD levels. The main decomposition stage of it was studied with IR track. The kinetic parameters[the apparent activation energy（Ea） and pre-exponential constant（A） of the first and second stages of decomposition reaction] were obtained by Kissinger and Ozawa＇s methods. Furthermore, the antimicrobial activity of HaL against wheat rust was investigated by spore sprout method.

探讨一种基于近红外反射光谱的人体血清白蛋白、球蛋白和总蛋白三种生化指标的无创检测方法。采集58例志愿者舌尖处近红外反射光谱,考虑这些光谱数据与血清蛋白浓度间因个体差异等存在非线性映射关系,在计算归一化光谱反射率及分析样本蛋白含量统计分布上,采用支持向量机分别建立三种蛋白成分近红外光谱定量回归模型,并与传统的偏最小二乘法进行比较。实验结果表明,支持向量机校正模型的预测效果较好且明显优于偏最小二乘法校正模型,对白蛋白、球蛋白和总蛋白的预测相关系数分别达到0.894,0.931和0.863,预测的均方误差为2.19,1.93和4.38。因此,支持向量机可有效抵抗活体检测定量分析中存在的非线性因素,提高模型的鲁棒性。同时也表明舌的近红外光谱信息能够较客观的反映人体理化指标的变化,用于血清蛋白含量的快速无创检测具有较高的可行性。

We investigate the nucleus 10Be using the deformed relativistic mean field （RMF） model and BCS theory. The calculated density distribution suggests two α clusters in the nucleus 10Be. According to BCS theory, the two valence neutrons transit to the first excited state 02＋ in a pair and form a 2-n cluster. By comparing the two neutron separation energy （S2n） with the single neutron separation energy （Sn）, and analyzing the difference between the neutron and proton rms radii （Rn-Rp） calculated by the deformed RMF, we suggest that 10Be is the best candidate for a two-neutron skin. The two-neutron skin clings to the 2α clusters closely and makes the two α clusters have cross and chain distribution.

观察食用菌饮食在运动员体能运动训练过程中发挥的重要作用,进一步探讨提高运动训练成绩、减少运动损伤的新方法.选60位运动员进行实验,并随机分为两组:对照组30例,在体能运动训练后,对照组给予普通正常饮食;实验组30例,在对照组饮食基础上,增加食用菌饮食:每日以金针菇30 g、香菇30 g、黑木耳20 g、银耳30 g、大枣6枚,炖汤食用.两组在体能运动训练结束后第1日清晨餐前及第5日清晨餐前各进行1次血清肌酸激酶(CK)、谷草转氨酶(AST)、乳酸脱氢酶(LDH)、血红蛋白、血细胞比容、超氧化物歧化酶(SOD)、丙二醛(MDA)水平测定并进行比较.结果:与训练结束后第1天比较,两组训练结束后第5天血清CK、AST、MDA水平均显著下降(P<0.01),LDH、SOD、血红蛋白、血细胞比容水平均显著升高,且实验组优于对照组(P<0.01).在运动员体能训练中,通过食用菌饮食调摄去改善运动性疲劳、运动性贫血和氧化应激损伤的效果是确切的,值得在体育教学中推广应用.
