Simultaneous thermogravimetry-differential thermal analysis （TG-DTA） was used to study the kinetics and the degradation of magnesium salicylate（ C14H10MgO6 ） in air. The results show that the decomposition proceeds through two steps. The kinetics of the first decomposition step was studied. The activation energies were calculated by using the Friedman and Flynn Wall Ozawa（FWO） methods, and the most probable kinetic model function was estimated using the multiple linear regression method. The values of the correlated kinetic parameters for the first decomposition step are E = 152.97 kJ/mol, lg（A/S^-1 ） = 10. 78, f（α） = （ 1 - α）^n（ 1 ＋Kcatα）, n =0. 691, and Kcat = 1. 3048.

Porcine reproductive and respiratory syndrome is caused by the PRRS virus (PRRSV),which has six structural proteins (GP2,GP3,GP4,GP5,M and N). GP5 and N protein are important targets for serological detection by enzyme-linked immunosorbent assay (ELISA) and other methods. Toward this goal,we developed an indirect ELISA with recombinant GP5 antigens and this method was validated by comparison to the LSI PRRSV-Ab ELISA kit. The results indicated that the optimal concentration of coated recombinant antigen was 0.2 μg/well for a serum dilution of 1:40. The rate of agreement with the LSI PRRSV-Ab kit was 88.7% (266/300). These results support the potential use of recombinant GP5 as an antigen for indirect ELISA to detect PRRSV antibodies in pigs.

With the development of quantum computing technology, quantum public-key cryptography is gradually becoming an alternative to the existing classical public-key cryptography. This paper designs a quantum trapdoor one-way function via EPR pairs and quantum measurements. Based on this, a new quantum public-key cryptosystem is presented, which offers forward security,and can resist the chosen-plaintext attack and chosen-ciphertext attack. Compared with the existing quantum public-key cryptos,eavesdropping can be automatically detected in this new quantum public-key cryptosystem under a necessary condition, which is also detailed in the paper.

采用沉淀法和水热法,合成了不同形貌的磷酸铁前驱体,并用碳热还原法得到LiFePO4/C正极材料。探讨了磷酸铁前驱体形貌特征对合成的磷酸铁锂电化学性能的影响程度。用XRD和SEM对产物物相结构、表观形貌进行了表征和分析。结果表明,水热合成的时间越长,磷酸铁的结晶性越好,趋于球形,电化学性能越好;但反应温度达180℃时,形貌趋向于椭圆,放电比容量反而较高。不同形貌的磷酸铁制备出的磷酸铁锂均为橄榄石结构,物相均一;不同形貌磷酸铁制备的磷酸铁锂正极材料电化学性能各异。磷酸铁形貌对磷酸铁锂正极材料电化学性能有影响,但不是决定因素。

从热力学的角度讨论毛细上升平衡高度以及毛细上升现象中的能量转换与守恒。在毛细上升的始终态之间设计了可逆途径,计算了可逆毛细上升过程中系统的赫姆霍兹自由能减少值,系统克服重力以及外压做功的值,并根据能量守恒定律推导出了毛细上升平衡高度和球形曲面的拉普拉斯方程。该方法拓展了热力学在表面现象中的应用,并有利于学生理解毛细上升现象的能量来源。
