| Abstract: | Various methods on the Earth nutaion theory, including celestial mechanics method, geophysical method and observational method, and nutation series are discussed. The recent development of observation and research work, especially of free core nutation, are introduced. Moreover,some deficiencies of the work and the prospect of the future developments are also pointed out. |
