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。

This paper presents an evaluation method based on psychological scale. Rank-order method or method of paired comparison is adopted to sort the images retrieved by different algorithms, then an ordinal scale is obtained. With presupposition of normal distribution, an equal interval scale is also obtained though POZ conversion. Thus different algorithms can be compared on these scales.

本文提出基于心理量表的情感图像检索性能评价方法，采用等级排列法或对偶比较法对不同算法检索出的图像进行排序，建立顺序量表，并在样本满足正态分布假设的前提下，将顺序量表转化成等距量表，以比较检索算法的优劣。

A new cyclic constitutive model for sands which can describe the deformation behavior of sands under combined variation of principal stress axes and magnitudes was developed based on the above physical fundamentals. And its effectiveness under the complex stress paths including cyclic rotation of principal stress axes is verified by a good comparison of model simulation with test results for sands.

交替运用计算几何中的最远点Voronoi图的性质和统计分析方法中的最小二乘法原理，可使最后参与求解最小外接圆的样本点数减至少量几个，相应算法的运算时间比以往的最优化算法快10倍以上。

After that, the important equation for calculating reverberation time is given based on the definition of reverberation time and least squares method. Finally, we use our new method to calculate reverberation time in a rectangular enclosure; we also compare our results with those given by experiment and Sabine's equation. The comparison shows that the new method is more effective and accurate than Sabine's equation in calculating reverberation time of small enclosures.
