| Liu Hong about 135 - about 210 years, characters Zhuo, Mengyin Taishan Shandong this Mengyin County, is well-known astronomer late Eastern Han Dynasty. Eastern Han Dynasty at the beginning of the astronomical community has been very active on the astronomical calendar of the debate after another, movement in the moon, Eclipse cycle, places where the winter sun, the Epoch launched a series of issues, such as a wide range of louis vuitton exploration, pregnant with a new breakthrough. In this historical background, Liu Hong, after more than 20 years of painstaking observation and research, and finally completed in 206 in the last Qian as his calendar, it appears this may be regarded as a good summary of the long-term debate, is to achieve a new breakthrough in the signs. To sum up, Liu Hong and Li Qian as nine in the following have made significant progress 23 First, Liu Hong found the return of the previous calendar year are too large length value, as in Qian Li, he set the new value of 365.2468 days, more accurate, thus putting an end to the accuracy of the return measured in the length of louis vuitton products suppliers the long-term back around so that the situation, and to develop the future generations the value of research in the right direction. Second, he affirmed the previous non-uniformity on the moon awareness campaign on the re-calculated on the basis of clearly identified the moon as early as two hours passed from the last location near point on the length for the 27.5534-day value, and the first non-uniform movement of the moon to carry out the numerical calculation correction table from the table on, that is, place the moon nearly every day after the actual moon line degrees degrees and the average line of the numerical difference between the tables, for the purpose of calculating the actual operation of the degree of the moon provides a realistic and practical approach, but also the topic of China39s ancient tradition of laying the cornerstone of calculation. Third, he pointed out that the moon is unique along the track of their own White Road movement, White Road and the angle between the ecliptic is about 6 degrees, with the current measurement results have been rather close. He also set up a White Road, from both inside and outside the degree of the ecliptic numerical form, which can be calculated at any one time the moon from the ecliptic in degrees north and south. Fourth, he explained the ecliptic Road intersection with the white background in the stars from east to west in the regression of the new astronomical concepts, and point out the yellow and white daily regression of specific value. Fifth, he proposed a new Eclipse-cycle value, which can have a fresh 346.6151 days in length. The value than his louis vuitton speedy predecessors and contemporaries to be derived from the value of accurate, its accuracy at the time the world is second to none. Sixth, he put forward the concept of food restriction that the new moon or look at the combined, only when the sun and the degree of yellow and white from the point of intersection is less than 14 33 39when it is possible the phenomenon of solar eclipse or eclipse, the 14 33 39on the limit as the food is fresh to determine whether to pay the value of clear and specific boundaries. | ||
