摘　　要：藏族传统天文历算学是我国传统天文历算学的重要组成部分.藏族传统天文历算是根据太阳和月亮的运动规律定义时间、制定历法的.确定太阳和月亮的运动规律与运动方位也是衡量藏族历法准确性的标准.文章根据藏传时轮历体系派对日月位置的计算口诀计算了藏历水蛇年3月15日(公元2013年4月25日)太阳与月亮的具体位置,并对筹算理论中所含有的天文学含义进行了符合现代天文学天体运动理论的阐释,最后根据日月位置的计算结果判断出该日是否出现月食现象.The sun and the moon,as the most significant celestial bodies,have been used to define time and calculate calendar based on their motion since ancient times.In the traditional Tibetan astronomical calendar,determining the regularity and direction of their motion is also the standard to measure the accuracy of the calendar.In this paper,the position of the sun and the moon on March 15th of the year of water snake in the Tibetan calendar was calculated,using the calculation formula introduced in the traditional Tibetan calendar system.And the astronomical meaning contained in the relevant calculation theory was introduced,which complies with the theory of celestial bodies movement in the modern astronomical sciences.F urthermore,according to the calculated results of their position on that day,it is examined whether there is a lunar eclipse or not.
