First of all, confirm the overall evaluating indicators and the base indicators of public transport network in Chinese large cities through repetitive comparison, discussion and consultation to relevant experts; among the base indicators in the overall evaluating indicators, composite the basic probability assignment of evaluation indicators with Dempster-Shafer Theory composition rule upon different experts' experiences and preferences of the expert group, and amalgamate the evaluations of different experts to further obtain the evaluation value of base indicators.

首先通过反复比较、探讨和征询有关专家的意见，确定大城市公交线网综合评价指标及子指标，在综合评价指标的子指标中，对专家组中不同专家的经验和偏好，用证据理论合成规则对评价指标的基本概率赋值进行合成，将不同专家的评价进行融合，获得子指标的评价值，然后通过突变理论将评价指标及子指标作为控制变量进行地面公交线网的综合评价，对北京市进行算例分析结果表明，该方法对大城市公交线网的综合评价是可行。

In this paper we establish an equilibrium model of intra-product specialization dominated by MNCs, and perform some empirical tests of China's trade volume growth using variables including technological conditions of trade, extent of similarity of economies, policy conditions of trade, extent of disintegration of production and level of per capita capital equipment; the empirical results support our basic conclusions.

构建跨国公司主导的产品内分工均衡模型，利用贸易的技术条件、经济体的相似程度、贸易的政策条件、生产非一体化程度和人均资本装配水平等变量对中国贸易量增长进行计量检验，其结果支持上述基本判断。

First design a reasonable XML Schema structure and under the restriction of XML Schema use XML to describe the UML class diagram and the related specification, and then extract the test specification of method from XML test script. Test specification refers to predicate sequences in the form of conjunctive normal form, extracted from basic constraint conditions of variables included in test scripts and expected outputs. Each conjunctive normal form can be transformed to an inequation set, and adopt 1×1 domain test strategy to every inequation set to produce the domain test matrix, which in turn produce the test case.

首先设计合理的XML Schema结构，并在该XML Schema的有效性约束下，用XML对UML类图及相关性约束进行脚本描述；其次对XML测试脚本进行分析，提取方法的测试规约说明，所谓测试规约说明就是从测试脚本中包含的变量的基本约束条件以及期望输出中抽取得到的以合取范式形式存在的谓词序列；每一合取范式对应一个不等式组，对每一个不等式组采用1×1域测试策略，生成域测试矩阵，最终得到测试用例。

When the production function was general, using theory of control and theory of stability, this paper discussed the production effect of government expenditure and fiscal policy, and got the expression of economic growth rate and structure stability of the economic variables when the production function was constant return to scale or increasing return to scale or decreasing return to scale, and pointed out how the interrelated parameters affected economic growth rate.

摘 要：在生产函数为一般形式时，利用控制论及定性理论的基本方法，讨论政府支出的生产效应和此时的财政政策。得出了当生产函数为规模收益不变、递增和递减时，经济增长率的大小及此时相关经济变量的定性结构，并指出了各种情况下相关参数如何对经济增长率产生影响。
