通过超期羁押的定义和分类的阐释来分析出我国产生超期羁押现象的内外因素。根据这些内外因素提出了解决超期羁押问题的对策,即在内因上,严格司法准入制度;进行长期有效的在职培训;树立正确科学的司法理念。在外因上,对超期羁押从时间、地点和人物三个层面加以控制。 Through the definition and classification of extended detention, we analyze the internal and external factors that cause the phenomenon of overdue detention in our country. According to these internal and external factors, the countermeasures to solve the problem of detention in extended period are put forward, namely, the internal and external system of judicial access; the long-term and effective on-the-job training; and the establishment of a correct and scientific judicial concept.
