Meridian Passage and ,oment, the local hour angle of the heavenly body will be either 0° or 180°, and the heavenly body is either due North or due South (i.e., bearing 180° or 000°) from the observer. The position line obtained, being at right-angles to the bearing, will instantly give the observer’s latitude. Although s古文字学 发表于 2025-3-29 03:33:13

While these can also be thought of as optical instabilities, we prefer to refer to them in the traditional way simply as multimode operation. In particular, this kind of operation can produce a periodic train of short pulses.Defense 发表于 2025-3-29 18:07:02
