Using the extended relativistic multi-configuration Dirac-Fock theory and the general-purpose relativistic atomic structure program 2(GRASP2) with quantum electrodynamical effect and breit correction, we have calculated the energy level structures, transition wavelengths, transition probabilities, oscillator strengths, energy level lifetimes, level widths and ionic average lifetimes of As-like Au~(46+), Ge-like Au~(47+) and Fe-like Au~(53+).

根据扩展的全相对论多组态Dirac-Foek理论，采用"多功能相对论原子结构程序GRASP~2(General-Purpose Relativistic Atomic Structure Program 2，1992)"，考虑量子电动力学效应和Breit修正，计算了激光金等离子体中类砷金Au~(46+)，类锗金Au~(47+)和类铁金Au~(53+)的能级结构、跃迁波长、跃迁几率、振子强度、能级寿命、能级宽度和离子平均寿命。

Total 122 entophytic bacterial strains were categorized preliminarily to 35 groups based on colony morphology. 16S rDNAs were amplified with universal primers of bacteria, all the strains could produce a single band about 1500bp. The PCR products were digested with restriction endoenzyme HaeⅢand Msp Ⅰrespectively, and the different patterns were obtained for each enzyme, by combining all the restriction patterns for the two enzymes, the 122 strains could be grouped into 39 16S rDNA genotypes. The results indicated that endophytic bacteria from oilseed rape were genetically diversity.

分离获得的122株内生细菌，根据菌落形态可以划分为35类；利用细菌通用引物对16S核糖体DNA进行扩增，获得约1.5 kb片段，分别用内切酶HaeⅢ和MspⅠ对扩增产物进行限制性酶切，产生不同的酶切图谱；根据酶切图谱聚类分析结果，所有供试菌株被归为39类，这一结果从遗传上显示油菜内生细菌类群的多样性。

The idea of our algorithm is equivalence class classification for continuous time is constrained by a relation between the remaining delay time of triggering event and time value of DTA clocks or the remaining delay time of other events.

和同类算法相比，我们的算法用更广义的延迟时间等价类取代同类算法中受事件先后顺序约束的单元延迟时间等价类，并且不必生成那些仅仅因为时间流逝而产生的状态等价类。
