复杂

The introduction of complex science requires us, by surpassing the traditional thinking ways, to take education as a system, complex and stable yet dynamic and self-developing at the same time, which provides us with a new angle and thinking way in our education research.

In order to solve dynamic, complicated and uncertain problems, multi-agents based distributed intelligence decision support systems, description and decomposition of complicated decision tasks, and cooperation and reasoning among multi-agents are elaborated in this paper. The details are given as follows. 1. Agent and ABDIDSS modelsIn allusion to the current problems of research on agents theory models, payoff and probability factors are introduced on the basis of mental state models of classical BDI of agent and joint BDI of multi-agents in this paper, mental state models of individual agents and joint metal state models of group agents based on payoff and probability factors are built up. Introducing payoff and probability factors satisfies requirements of uncertainty and self-benefit of agents to the environments.

It is revealed that there is an evident fractal character for urban thermal surface profiles. The fractal dimensions in eight directions are between 1.530 0 and 1.780 6, which reveal the complexity of different thermal profiles. By analyzing the factors to UHI, thermal fractal characters are mainly due to the scope and shape of builtup area and land surface properties.

热场表面剖面线的分维数揭示了3个方面的意义：首先不同的分维数反映热场不同方向上温度变化的复杂程度；其次，相对于城市中心，反映不同方向上城市边界形态的差异性；第三，进一步揭示不同方向上，下垫面土地利用类型空间组合变化的复杂程度。

Independent-samples t-test is used to compare means of the experimental and control groups.The statistical results reveal that collocational competence with the sub-technical terms of the experimental group is significantly higher than that of the control group. However, the CBSTT model's effect on the simple nominal phrase collocational competence is more significant than the effect on the complex nominal phrase collocational competence. From the perspective of production competence, the overall results of the experimental groups are significantly higher than the overall results of the control group. The complex nominal phrase production competence is not significantly developed at the beginning of the experiment. With the progress of the experiment, the differences from the two groups become salient.

在短语搭配能力方面，实验组学生的总成绩明显高于对照组学生，其中实验组简单短语的搭配组合能力与对照组学生存在显著差异，但复杂短语的组合能力上两组差异不大；在产出能力方面，实验组学生的总成绩也明显高于对照组学生，实验组简单短语的产出能力与对照组学生存在显著差异，复杂短语的产出能力开始没有显著差异，随着实验的进行差异越来越显著；在通过词汇重复手段以构成语篇衔接方面，实验组学生的成绩和对照组的学生无显著差异。
