对跖点是立脚点与地心的连线延长后,与地球表面的另一个交点。通俗地讲,地球上两个脚对脚的地方,互为对跖。地球上的任何地方都有且仅有一个对跖点。我们要是知道了某一地方的地理位置,那么就可以知道该地对跖点的位置。为什么呢?原来对跖点纬度和经度是关于地心呈中心对称的。因此它们的纬度数相同,只是南纬、北纬差别而已。而经度则是互补的(即两地的经度数之和是180°),也即就是东经、西经之别而已。若一者为东经,则另一者为西经。所以关于对跖点有这样一句口诀:“纬度相同分南北,经度互补分东西。”另外,两个对跖点经度相差180°,就是跨了12个时区,因此我们还可知道他
It is another point of intersection with the earth’s surface after the extension of the connection between the footing point and the center of the earth has been extended. In layman’s terms, two feet on the earth are opposite each other. There is only one confrontation point anywhere on Earth. If we know the geographical location of a place, we can know the location of the place. Why? The original latitude and longitude are symmetrical about the center of the earth. Therefore, their latitude is the same, but it is only the difference between latitude and north latitude. Longitude is complementary (that is, the sum of the longitude of the two places is 180°), that is, the east longitude and the west longitude are different. If one is east longitude, the other is west longitude. So there’s a saying about confrontation: “The latitude is the same as the north and the south, and the longitude is complementary.” In addition, the two confrontation points differ in longitude by 180°, that is, they cross 12 time zones, so we can also know him.
