Fano Resonance in Landau Fermi and Luttinger Liquids

With a two-channel model, we study the influence of temperature, external voltage and magnetic flux on the line shape of the Fano resonance, and show that in the Luttinger liquid case, the background transmittance and the asymmetric parameter depend strongly on the temperature and external voltage, while for the Landau Fermi liquid case they are nearly independent of these parameters in the low energy region. Moreover, we demonstrate that the asymmetric parameter changes periodically with an external magnetic flux, which is consistent with the recent experimental data.     

高效液相色谱法测定肿瘤患者血浆中磷酸酶的活性

对磷酸酶根据其作用的最适pH不同分为碱性磷酸酶(AKP)和酸性磷酸酶(ACP)两种。对血浆中磷酸酶的测定,已进行了广泛而深入的研究,证明血中酶活性的变化与一些恶性肿瘤的发生发展有一定关系,故作为肿瘤酶学诊断指标之一。近年来,由于高效液相色谱(HPLC)技术的发展,特别是各种高效能色谱柱的出现以及检测器的发展,国外已有人将这种技术应用于磷酸酶及其同工酶的分离及定量

高效液相色谱法同时测定肿瘤患者尿中假尿苷和肌酐的含量

An HPLC method for the simultaneous determination of pseudouridine(Pu)and Cretinine(C)in urinewas established;The recoveries of Pu and C were 92. 09±3.5%and 83. 01±5.7%respectively. The calibra-tion curves were linear within the concentration range of 2～200μg/mL for Pu and 5～300μg/mL for C. The detection linilts for Pu and C were 2. 15μg/mL and 4.75μg/mL. The method is rapid,sensitive and reliable.
