| 摘 要： | Using the characteristic
values of sunspot number variations during the descent and ascent of solar cycles,a neural network is designed to
make long-term predications of the ascending period and the maximum smoothed monthly mean
sunspot number for the Solar Cycle 23. Moreover,the factor of geomagnetic disturbance is also added as an
input. The trained and tested results from Solar Cycle 12 to 22 have been obtained.
Finally,the
predictions of the ascending period and the maximum smoothed monthly mean sunspot number
are given for Solar Cycle 23.
