随着社会的快速发展,95后大学生的性观念也会随之发生变化,笔者以工科院校的学生为例,对95后大学生的性观念、性行为进行调查研究。从国家、学校、家庭等方面加强性教育,对于维护性心理健康,形成良好的大学生性文明,有着非常重要的现实意义。

By mass-selected low energy ion beam deposition, amorphous carbon film was obtained. X-ray diffraction, Raman and Auger electron spectroscopy depth line shape measurements showed that such carbon films contained diamond particles. The main growth mechanism is subsurface implantation. Furthermore, it was indicated in a different way that ion bombardment played a decisive role in bias enhanced nucleation of chemical vapor deposition diamond.
