Distance measures for quantum mechanical states are widely used in the theory of quantum information processing and quantum *** this paper,we propose two families of new distance measures for quantum states and their correspond- ing families of quantum distinguishability *** these distance measures are proved to satisfy the three properties of a dis- ***,based on the results about the trace distance and fidelity,we derive simple upper bounds and lower bounds for these new distance measures and their corresponding quantum distinguishability measures.

Mandatory access control is an important aspect of safeguard protection in modern operating systems. With respect to the use of authorization hooks in the MAC framework, we study the correctness of XSM module in MAC based on the XEN system. This paper defines authorization verification, and also provides the respective authorization methods. We introduce the selective symbolic execution method, and realize a correctness verifying testing tool. This tool can verify the accuracy and completeness of the hook functions in MAC with high path coverage and low false positives.

对橡胶-大叶千斤拔复合生态系统和橡胶纯林进行连续3 a的对比观测研究,结果表明在橡胶林里种植大叶千斤拔能促进橡胶生长,橡胶平均基径、平均胸径和平均树高分别比橡胶纯林高出11.0%、9.62.和3.78%。与橡胶纯林相比,混作后土壤含水量的季节变化较为缓和且旱季含水量较高;且0～10 cm和10～30 cm的土壤容重每年分别约下降0.03 g/cm3和0.01～0.02.g/cm3。随着种植年限的增加,土壤中有机质、全氮、全磷、全钾含量都呈现出先降后升的趋势,而在对照中土壤有机质、全氮、全磷、全钾含量均呈现不断下降的趋势。表明混作后植物的生长及土壤养分状况比橡胶纯林都有所改善。

The PSV?NS3, an expressing recombinant plasmid of dengue virus type 2.NS3 protein, was injected directly into the quadriceps of Balb/C mice to explore whether it could inducing immune response. The splenic T cell subsets of two groups was analysed by flow cytometry. It was found that the percentage of CD4+ and CD8+ T cells of experimental group were significantly higher than those of the control group. The titer of IgG antibody was as high as 1∶5 12. in experimental group, but it couldn’t be detected in control group by ELISA. The western blot further proved that the IgG antibody was specific for NS3 protein. Those results Suggested that inoculation Balb/C mice with PSV?NS3 could inducing immune response, and the NS3 protein might be used as the candidate protein of DNA vaccine of dengue virus.
