In the current library environment, information created using AACR2 rules is generally expressed using MARC 21 encoding. One interesting point is that catalogers speak to one another in MARC, using tagging shorthand to express their ideas about bibliographic data.

当今图书馆以AACR2规则编目的记录一般都是以MARC21格式编码，一个有趣的现象是编目人员彼此之间谈到编目数据，满口都是MARC的缩略语。

Using some simple mathematic formulae and cladograms, present author put forward a conception for the resolution of the evolutionary temporal order of DNA sequence data in phylogenetic analysis, and point out a possible rational resolving range.

通过简单的数学公式和分支图形，作者提出系统发育分析中DNA序列数据演化时序的分辨率概念，并指出可能合理的分辨率范围。

In order to get out from the cockamamie work in road route design for designers, on the basis of studying the internal relations among local schemes, local scheme was decomposed to small unit logic schemes; the directed network was used to represent the topological connection; the united data structure of point-arc was used to express a network graph. Based on the shortest path theory, the combinatorial optimization algorithm that can search optimal logical schemes of some targets in the network graph intelligently and can form the whole scheme automatically was put forward.

为了使设计者从道路线路设计的繁重计算统计工作中解脱出来，在研究了局部方案间内在关联的基础上，提出了将局部方案分解为更小单位的逻辑方案，用有向网络图表示逻辑方案间的拓扑关系，采用节点－弧段联合数据结构来表示网络图；同时基于最短路径理论，提出了在网络图中智能化搜索综合指标最优的逻辑方案集，自动形成整体方案的组合优化算法。
