The result was consistent with morphology of Pleuronectiformes on the whole.In the topology founded,Scophthalmus maximus and Solea senegalensis formed an independent branch each other and showed far relationship with species of Bothidae and Pleuronectidae,the phylogenic position of Solea senegalensis is accorded with the reported result of analysis made by mitochondrial genome.

运用PAUP软件对15种鲽形目鱼类与另外7种不同种属鱼类进行了分子系统进化树分析，结果与根据传统的形态学和生化特征分类进化地位基本一致，在15种鲽形目鱼类中只有大菱鲆和塞内加尔鳎各自单独形成一个分支且与鲆科和鲽科鱼类相距较远，其中塞内加尔鳎等种类的分类地位与根据线粒体DNA序列分析的系统发生模式基本吻合。

The complexity of the distribution of Purkinje fibers has led to great difficulty in ECG simulation research.

由于Purkinje纤维在心室内膜上分布的复杂性，给心电仿真的研究带来很大的困难，本文对此进行了很有意义的探索，即不仅把心肌单元按动作电位分类，又将其按传导速度分类。

The sales manager can then send an automated mailing each week for the customers in the category Customers to recontact'.

另一种分类规则将所有满意度低于4.3的客户改变业务伙伴分类为'再联系客户'。

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。
