Dispersion Equation of Low-Frequency Waves Driven by Temperature Anisotropy
《Plasma Science and Technology》2012年第10期880-885,共6页陈玲 吴德金 
supported by National Natural Science Foundation of China(Nos.10973043,41074107);Ministry of Science and Technology of China(No.2011CB811402)
The plasma temperature （or the kinetic pressure） anisotropy is an intrinsic characteristic of a collisionless magnetized plasma. In this paper, based on the two-fluid model, a dispersion equation of low-frequency ...

Basic Plasma Processes in Solar-Terrestrial Activities被引量：2
《Chinese Science Bulletin》2012年第12期1353-1356,共4页WU DeJin FENG HengQiang 
supported by the National Natural Science Foundation of China(10973043 and 41074107);the National Basic Research Program of China(2011CB811402)
Within the known universe,more than 99%of all observable matter is plasma,a state often highly dynamic and far from thermal,as well as mechanical,equilibrium.In particular,for our own solar-terrestrial system,various ...

On theories of solar type Ⅲ radio bursts
《Chinese Science Bulletin》2012年第12期1357-1361,共5页WU ChingSheng 
supported by the National Natural Science Foundation of China(10973043and41074107);the National Basic Research Program of China(2011CB811402);supported in part by the National Central University in Taiwan,China
In solar radiophysics,many theories for type Ⅲ bursts have been proposed during the past 60 years.Almost all these theories are based on the plasma hypothesis,which assumes that(i)the radiation is mainly generated by...

Euler potentials'discontinuity in the presence of field line-aligned currents
《Chinese Science Bulletin》2012年第12期1436-1437,共2页HUANG TianSen WU DeJin 
supported by the National Natural Science Foundation of China(10973043 and 41074107);the National Basic Research Program of China(2011CB811402)
Since their use in the study of charged particle motion in the 1960s,Euler potentials(α ,β)have been widely employed as magnetic field coordinates in both space plasma and fusion plasma studies.People related them t...
