The author discussed the effect of opacity on stellar evolution and concentrated on the mechanism of triggering blue loop by using Padova stellar model. It shows that extended mixing at the bottom of the convective envelope changed the interior hydrogen profile, which triggers or suppresses blue loop. Laboratory astrophysics, which is a cross subject of astrophysics and plasma physics, combines the demand of accurate data of radiative opacity with the latest advances in high intense lasers to devise the third independent method to study the radiative opacity. On the basis of the comparison between stellar material and laser-produced plasma in terrestrial laboratory, the desirable way to study opacity in laboratory and the brief introduction to the experiments relative to opacity are given.

With the comparison between Western and Chinese classical literatures , this paper points out that there is a fundamental difference between the two FIRE images. The FIRE image in western literature is featured by the obvious spirituality, whereas the FIRE image in Chinese literature is featured by secularity. But the traits of the both images of FIRE have changed more or less in the 20th century.
