On the basis of the characters of taking-out and placing in shunting on actinoid private lines, the best schedule of taking-out and placing-in of wagons of several non through trains arriving at the railway station successively is analyzed. Collection and delivery shunting being treated as within one integrated system, a mathematical model is established with the objective to minimize the detention vehicle hours of wagons at a station.

基于放射形专用线取送车作业的特点，针对非直达车流取送车问题中，多列列车相继到达车站时，对如何确定合理的取送车顺序进行分析将取送车作业作为一个系统进行整体考虑，以货车在站停留的总车小时消耗最小为优化目标，建立数学模型。

At the same time, on the base of analysis of the present situation, the development trend and the leading edge technology, the necessity and feasibility about the exploitation of the full hydraulic bulldozer"s sate monitoring and fault diagnosis system is given; According to the structure, working feature and working environment, it works out system schema and system composition; The system is divided into display module, communication module and fault diagnosis module by means of block design, the implementation method and key parameter are also given; In light of the features of the full hydraulic bulldozer, the state monitoring and fault diagnosis platform composed of controller RC6-9 and display DI2/10 is designed based on CAN-Bus and the hardware design is completed; It lists the measured values and state of monitored parameters which should be real-time displayed in monitoring module as well as the data which will be transmitted; Furthermore, On the base of the study of, it gives 34 kinds of constant faults" diagnosis methods; Using BODAS software and DPS software, it compile the program code of the controller and the displayer; At last, this paper design and make the simulation test device of control system of construction machinery, through the experiment, the realizability, the categoricalness, the reliability, the stability and real-time are tested, in addition, the improved methods are given.

本文收集整理了国内外智能推土机研究的相关文献资料，综合分析了国内外智能推土机的研究现状、发展趋势和前沿技术，论证了开发全液压推土机智能系统的重要组成部分&全液压推土机状态监测与故障诊断系统&的必要性和可行性；根据全液压推土机的结构、作业特点和作业环境，制定了全液压推土机状态监测与故障诊断系统方案，确定了系统的结构组成；采用模块化设计方法，将整个系统分成了显示、通信和故障诊断三个模块，给出了各模块功能的实现方法，确定了各模块的关键技术参数：选用RC6-9和DI2／10作为系统的控制器和显示器，用CAN总线搭建了系统的通信平台，完成了系统的硬件设计；确定了系统监测参数和通信数据，对全液压推土机常见故障特征进行了分析，给出了34种常见故障的诊断方法；在BODAS软件和DPS软件的集成编程环境下，编写了控制器和显示器程序；设计并制作了工程机械控制系统模拟试验板，并在此基础上通过多次的程序调试与试验，对所设计的全液压推土机状态监测与故障诊断系统功能的可实现性、完备性、可靠性、稳定性和实时性进行了检验，证实了此系统的可行性，并提出了进一步的改进方案和措施。

Furthermore, the brain area of anterior cingulated cortex revealed different response type under emotional and non-emotional interference condition, i.e, activation of ACC in color-word Stroop task was enhanced along with increasing of cognitive conflicting interference. Yet in emotional Stroop task, activation of ACC is reduced when the negative emotional interference was enhanced. This phenomenon suggests that ACC possess a flexible conflict monitoring mechanism and adaptive mechanism, thus providing evidence for the theory that ACC plays an important role in the cognitive and emotional interaction.

其结果显示，背侧前额叶、前扣带回是共同参与情绪与非情绪干扰的执行抑制的脑区，其中，前扣带回在情绪与非情绪干扰两种条件下出现不同类型的反应方式，即前扣带回在色字Stroop作业中随认知冲突干扰梯度的增加而增加，但在情绪Stroop作业中随负性情绪干扰梯度的增加而减少，体现出前扣带回具有灵活的冲突监控与适应性机能，支持前扣带回在认知与情绪交互作用中扮演重要角色的理论。
