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.

本论文就开展辐射不透明度实验室研究的背景、内容和意义进行了介绍，并在对实验室的激光等离子体和天体环境下的恒星物质两者差异和相关性的认识基础上，论证了开展辐射不透明度实验室研究的可行性，而且对世界上正在开展的类似研究予以简要介绍，期望可以将天体物理领域对辐射不透明度数据可靠程度的质疑以及对其准确数值的广泛要求，与激光等离子体物理实验的最新进展相结合，推进辐射不透明度实验室研究，为辐射不透明度的研究开拓了继天文观测和理论计算的第三种独立的手段。

In this article, firstly embedded system development actuality and trend are introduced, a project of palmtop type image display system based on embedded network server is proposed. Secondly based on TI company special DSP processor TMS320DSC21, a brief introduction of components of system hardware is done. Following this the theory and reality analysis of JPEG image decompression is done, it is one of the most important technique in digital image process.
