| 外文摘要： |
Laboratory astrophysics is one new subject that research astrophysical phenomenon by ex-
periments facilities. It is significant to know the evolution of astrophysical plasma by studying the
plasma dynamics in a controlled experimental environment. Then, the interaction between the so-
lar wind and the Earth's magnetosphere has always interested in astrophysics. This thesis presents
thegenerationofsteady-stateplasmaandmagneticfieldinthelaboratorywithShenguangIIlasers，
four laser beams are applied to the two sides of the target respectively. And the solar wind is gen-
erated by the interaction of the laser and the CH target, and the dipole magnetic field is generated
by the interaction of the laser and the solenoid. It is observed that there is a significant density ac-
cumulation at the front end of the dipole magnetic field，which is similar to the top of the Earth's
magnetosphere in the astrophysics environment.we proposed a simple scheme to produce strong
magnetic fields due to hot electron flow in an solenoid coil heated by high power laser pulses，The
magnetic field strength at the coil center is measured to be 70 T. The generation mechanism of the
magnetic field is straightforward and the coil is easy to be fabricated，we utilized such a strong
magnetic field in laboratory astrophysics experiments. With the development of the laser-driven
magnetic fields, they are expected to be used in more laser-plasma researches.
