  摘要采用多因素分析方法从目前普遍认可的反映科技期刊学术水平的多项评价指标中筛选出影响作用大的指标，构建期刊学术水平评估指标体系。依据新的评估指标体系建立期刊方阵四类判别函数模型。
• In terms of sub - shifts of finite type determined by an irreducible matrix , affine maps of compacted connected metric abelian group and continuous maps of tree , the two concepts of topologically ergodic map and topologically transitive map are identical
  指出对于由不可约方阵所决定的符号空间有限型子转移而言，或紧致交换群的仿射变换及树上连续自映射而言，拓扑遍历与拓扑可迁这两个概念是一致的。
• Firstly , the basic theory of the ultra - short baseline system is dissertated . and then , several typical localization model of four cell lineup is analyzed and investigated thoroughly . a optimal localization model is educed by contrasting performance and analyzing precision
  首先论述了现有超短基线被动声定位系统的基本理论，紧接着深入研究了几种典型的四元方阵的定位模型，通过性能对比、精度分析，讨论得出了最优的定位模型。
• I saw here , your excellency , the attack of the pavlograd hussars , zherkov put in , looking uneasily about him . he had not seen the hussars at all that day , but had only heard about them from an infantry officer . they broke up two squares , your excellency
  “大人，在这儿我看见保罗格勒兵团的官兵冲锋陷阵， ”热尔科夫神情不安地向四下张望，插了一句话，其实在这天他根本没有看见骠骑兵，只是从一名步兵军官那里听到他们的消息， “大人，打败了两个方阵。 ”
• In the paper , computational sophistication is applied to compute the basic solution matrix of a sort of two - dimensional periodic differential equation which contains two parameters . the matrix makes it realizable to study the stability of two - dimensional periodic differential equation , here , the following is proved in the paper : only if a ( t ) , b ( t ) , c ( t ) , d ( t ) satisfy some quantity conditions , is exponentially asymptotically stable
  <中文摘要> =本文应用计算技巧，计算出一类含双参数的二维周期系统的基本解方阵，以这个基本解方阵为依据，研究二维周期系统的结构稳定性。所得结论是：只要之间满足一定的数量关系，则该系统指数型渐近稳定。
