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.

Firstly, electrization knowledge related to the research is introduced. After a deep study on various contact loss detection techniques, especially on the electric arcs detection techniques, we draw the conclusion that the untouched detection technique based on phototube sensor can acquire exact contact loss information, and will to be the leading technique for contact loss measurement in future. Secondly, combining with the special railways system in our country, we analyze the cause of the arcs, and the influence on the power supply system and the on board traction drive due to the arcs in detail, and study the arcs' spectrum characteristic. We also analyze detecting principles and put forward with a method - using phototube sensor to detect the contact loss arcs, conceive the configurations and detection flows of the measurement.

In order to investigate the effect of IFN-γon the expression of TNF-αin the hypothala- mus-pituitary-ovary axisof RU486-induced aborted SD rats, RU486 was used to establish the abortion model, then the aborted rats were administrated with different doses of IFN-γintraperitoneal injection, the method of immunohistochemical ultrasensitive SP was us- ed to study the variation of positive TNF-αcells in hypothalamus, pituitary, ovary and uterus in normal pregnant group A, aborted model group B and three different doses of IFN-γgroup C,D,E. The main goal of this research was to study whether the low dose of IFN-γcould have a protective function to pregnancy and the mechanism of its function so as to provide morph- ologic basis for the scientific using of IFN-γin the process of animal abortion control.

为探讨IFN-γ对流产大鼠下丘脑-垂体-卵巢轴(hypothalamus-pituitary- ovary-axis，HPOA )TNF-α表达的影响，本试验用米非司酮(RU486)建立SD大鼠流产模型，通过腹腔注射不同剂量IFN-γ，采用超敏感免疫组织化学SP法(链霉素抗生物素—过氧化物酶法)，观察了孕13天(d13)SD大鼠正常妊娠A组、流产模型B组、不同剂量IFN-γC、D、E组下丘脑、垂体、卵巢、子宫TNF-α的表达变化，探讨低剂量IFN-γ对妊娠是否有保护作用及其作用机制，期望能为在妊娠过程中如何科学应用IFN-γ防止动物流产提供形态学依据。

Since the number of trips is a non-negative integer, truncated, and of endogenous stratification, this study empirically analyzes its recreational benefits by the On-site Poisson and truncated negative binomial with endogenous stratification of the Travel Cost Method. Besides, this study adopts TNBES to see how the number of trips disperse and takes the consumer surplus to assess benefits. As to visitors' valuation, this research uses the ordered probit to do empirical analysis and then divides all satisfaction factors by the factor analysis and cluster analysis into four factors and two clusters, which then are taken as explanatory variables.
