台湾高等教育中的学生管理主要是以制度约束人;而学生的培养模式与美国相似,注重通才教育.这些都与大陆高等教育中"因材施教"和"厚基础、宽专业"的指导思想有一致性,但在具体的实施方式上有着较明显的区别.文章从高校学生管理模式与培养模式两个角度分析,具体阐述了台湾高等教育在这两方面的特点及与大陆高等教育的区别.最终提出了台湾高等教育中学生管理和培养模式对大陆高等教育的启示与展望.  相似文献   

Molecular dynamics simulation study on behaviors of liquid 1,2-dichloroethane under external electric fields

Molecular dynamics simulation was carried out to study the behavior of liquid 1,2-dichloroethane molecules under external electric fields including direct current field, alternating current field and positive-half-period cosin field. The maximum applied field strength was 10⁸ V/m, the maximum frequency of the alternating current field and that of the positive-half-period cosine field was 10¹² Hz. The simulation revealed that the field type and field strength act on the population of the molecular configuration. In the strong direct current field, all trans forms converted completely into gauche forms. Order parameter and the correlation of the system torsion angle were also investigated. The results suggested that these two dynamical parameters depended also on the field type and the field strength. The maximum of order parameter was found to be at 0.6 in the strong direct current field.  相似文献
