The cross-section and surface structures of wing membranes from the ctenochasmatid pterosaur Beipiaopterus chenianus were observed through a scanning electron microscope (SEM). The results show that the wing membrane contains a high density of blood vessels, implying strong thermoregulatory function, similar to that of a bat wing membrane. This is the first comparison of the microstructures of pterosaur wing membranes with those of the modern bat. It is inferred that a bat-like physiology exists, at least in relatively small pterosaurs suggesting that these pterosaurs were warm-blooded, active fliers.

一、高职计算机基础教学现状 第一，高职生的能力和水平差异较大，对于计算机的认识和掌握程度参差不齐，现有课程方案的设计很难适合所有学生。对于计算机基础薄弱的学生来说，完成教师布置的练习都比较困难；对于计算机基础好的学生来说，教师布置的练习无法达到扩展训练的目的。产生这种现象的原因，是学生无法自主规划课程内容。 第二，调查结果显示，高职生普遍存在依赖性强、自主学习能力弱的通病，不善于拓展学习内容，
