They are: the achievements of textual research and exegesis of Zhu Zi Xue in Qing Dynasty; the promoting effect of the introducing Western theories that took on the research of Chinese classical logic; taking the doctrine of Moism and scientific logic method as a methodological weapon for propagating reformist thought and Liang Qichao"s favor to Mo Zi and theory of Moism.The second part is about Liang Qichao"s achievements of logic and methodology: he analyzed induction and deduction, and thoroughly analyzed induction in particular, and his thought about those was mainly correct; he analyzed comparison as a component of induction and discussed the cognitive function of comparison, he also explained how to use comparison in the research of history; he not only explicated the thinking process of analytical method and synthetic method, but also integrated the two methods with studying history and reading history , and turned them into specific research methods of history ;he expound the rule of causal law , just as Leibnizs principle of sufficient reason in Western modern times and the law of sufficient reasonin universal logic; he discussed nominal classification, and analyzed wrong classification of the forefathers, then he pointed out the significance of clarifying the basic of division .

不足在于：①梁启超对于各种科学方法的论述不够系统、全面；②梁启超比较研究方法仍存在一些缺陷，他的比较研究主要是将墨家论式与西方逻辑的三段论(有的与印度因明的三支作法)形式作求同研究，缺乏系统性和全面性，而且对三种逻辑的共同点和差异点的分析也缺乏理论深度，加之梁启超不懂得数理逻辑，缺乏精确的数理逻辑工具，因而使这种对比分析缺乏严密性和精确性。

The method is shown about how the model is constructed and applied to classification. Two sorts of kernel function are applied to SVM, they are multinominal function and radial basis function. The model and algorithm are applied to some documents of China periodical document database and classification results illustrate its practicability.

Taking household\'s land use preference as classification rule, household agent types were divided though classification tree. Different choosing process of current production strategies and theirs probabilities after expiration of GFGP chosen by various types of household agents\' were put forward by experience-weighted attraction model based on bounded -rational approach. Finally, forecasting the results of households\' recultivation behaviour after the expiration of GFGP by scenario analysis method. The results show that relative policies are useful to rectify deviation of households\' bounded-rational behaviours and reinforce outcomes of GFGP.

以农户家庭户主的土地利用选择偏好作为分类依据，采用分类树方法对农户智能体类型进行划分；基于有限理性决策理论，引用经历—权重吸引模型，对农户智能体的目前生产策略决策过程和退耕还林政策期满后农户对不同生产策略的选择概率进行了分析；最后，在ERDAS环境下对退耕还林政策期满后农户的复垦行为进行了情景分析，认为政府制定并实施的相关政策措施对于纠正农户的有限理性行为偏差，维持和巩固退耕还林政策成果具有重要作用。
