方法：采用大鼠松果体摘除模型，运用原位杂交技术，探讨了在冬至、夏至SD雄性大鼠睾丸C Fos和C JUN的mRNA的变化规律。

Adopting rat pinealectomy model and in situ hybridization technology, we discuss the varying regularity of c fos and c jun mRNA in male rat's testis in midwinter and in midsummer.

结果：睾丸C Fos和C JUN的mRNA具有冬至表达强、表达量多，夏至表达弱、表达量少的特点和趋势。

Results: the expression degree and the amount of c fos and c jun mRNA in testis are of intensity and plenty feature and trend in midwinter while weak and insignificant in midsummer.

本文在前人已公布的暴时电离层动态资料的基础上，进行了太平洋地区冬至与夏至期间电子总量和F层特征的分析研究，取得了新的结果。

In this paper, features of the total electron content and F-region of the ionosphere over the Pacific area during the typical storms are analysed on the basis of published data and some new results are presented.

采用大鼠松果体摘除模型，探索了冬至、夏至SD雄性大鼠血清睾酮（T）、黄体生成素（LH）及卵泡刺激素（FSH）的变化规律。

The changes in the levels of serum testosterone ( T), luteotropic hormone ( LH) and follicule stimulating hormone ( FSH) were studied in the pineal body removed SD male rats at the Winter Solstice and the Summer Solstice.

并在此基础上，计算了全国6个典型地貌类型区，在春秋分日、夏至日和冬至日，两个空间分辨率下（500m和1km）地面日照时间的空间分布。

In this study, 6 typical terrain areas within China were selected and their spatial distributions of sunlit time on the vernal and autumnal equinoxes, the Summer Solstice and midwinter day in two different resolutions ( 500m and 1km) were calculated using the developed model.
