Abstract content
The time variation of the chaotic feature of the energy series of cosmic rays shows a periodic behaviour with the rotation of the earth. The periods are 1.0day and 1.3day. The energy series of cosmic rays are evaluated by the formula of Nishimura-Kamata-Greissen. The chaotic feature is found by the correlation dimension analysis and Lyapnov exponent analysis. The periods mean that the chaotic series cosmic rays arrive from definite directions.
