In this paper, we present a theoretical derivation of Ha line luminosity of the expanding envelope of SN1987A by use of the hydrogen recombination theory. We find that there is a remarkable deviation between the observed Ha line-variation and our calculated one if a constant temperature is assumed. Such a deviation implies the variation of temperature and the evolution of temperature can be easily extracted from this deviation.

本文介绍了超新星SN1987A爆发六年来关于其包层温度演化的研究情况,温度是研究超新星的各种物理过程的一个基本参量,然而目前对温度的各种估算十分弥散,结果相当不确定。本文利用辐射转移理论的逃逸几率方法,导出Ha线辐射理论光变曲线,通过与观测曲线的比较,可定量地导出超新星气壳的温度演化行为。这一模型的结果与他人的结果有较好的符合。同时,我们的结果表明,在爆发500天以后,温度反而随年龄上升,可能的解释在于随着气壳的膨胀,电子及离子的密度迅速减小,而使得复合冷速率大为减小,而加热却继续着。

The stable isotopes of carbon, hydrogen and oxygen in stalagmites from the Zhoukoudian Cave,Beijiop were analyzed using the stable isotope geochemical method. The stalagmite samples fromZhoukouian were dated by the U series method. The records of paleoclimate evolution in Zhoukoudian[ (8 - 5) ×10 4a] have been obtained, and are compared with the curves of sea-level change for the Bo-hai Gulf, China.

用MAT—251型同位素气体质谱仪对北京周口店洞穴石笋进行δ(18)O、δ(13)C.δD的稳定同位素的测定,并用α谱仪对石笋进行了铀系不平衡年龄测定。用同位素古温度测温法计算出不同地质年龄的古温度,得出距今8~5万年间该地区古温度的演化规律,并与同期渤海的海平面变化曲线进行对比,发现它们的海平面与古温度变化曲线十分一致,说明该地区8~5万年间海平面的变化主要是由古温度的变化引起的。
