报告内容摘要：
      The solar wind originates in the solar corona, fills the entire space between and beyond the planets with the solar plasma and magnetic field, and comes to a full stop at the heliopause more than hundred astronomical units away from the Sun. The sources of the solar wind in the Sun's corona and its spatio-temporal variations in the inner heliosphere will be discussed. The solar wind as magnetohydrodynamic fluid and kinetic entity is turbulent and permeated by waves and convected structures on all scales that cover many orders of magnitude. The excitation, evolution and dissipation of the turbulence are discussed, and its statistical properties (spectra, scaling laws and intermittency) are illustrated, using magnetic-field and plasma data mainly obtained from the Helios and Ulysses space missions.
