When the IMF turns southward, a great amount of magnetic energy is stored in the magnetotail, and the electric field across the magnetotail substantially en-hances. As long as magnetic reconnection (MR) in the mag-net...

As well known, the magnetic cross-tail component By in the magnetotail is in direct proportion to the in-terplanetary magnetic field (IMF) By component. And the polarity of IMF and plasmoid / flux rope By components d...
SINCE the concept of random walks (RW) was propounded formally by Pearson in 1905, there has been extensive research in mathematics. Then it expanded to many areas such as physics, chemistry, biology, engineering, com...

When a polymer chain has only one end group attaching to the boundary and all the other segments are located in the half-space divided by the boundary, it is defined as a tail chain~. Obviously, the model of tail chai...

The self-avoiding walk (SAW) is an important model greatly different from the normalrandom walk in mathematics. Since a site that has been occupied once cannot be visitedagain by the walker, the SAW is not a Markov ch...

The large accelerations of plasma were observed early in type-Ⅰ comet tail. The accelerations can reach 300 cm/S^2. Recently, the direct measurements for comet G-Z show that the energy of particles reaches 2×10~5 eV...
Ⅰ. INTRODUCTION Hydrogenated amorphous silicon-carbon (a-Si1-xCx:H) film is an important amorphous photoelectric semiconductor material having a wide and variable band gap. It reduces the interface reflection and sur...
I.INTRODUCTION The large-scale phenomena of the plasma tail of Halley’s Comet after its passage through the perihelion have been observed with a tracking camera having an aperture of 10 cm, a focal length of 25 cm an...
Ⅰ. INTRODUCTION The famous Comet Halley (whose period P=76.1 years, orbital eccentricity e=0.9673, inclination of orbit i=16202) threw men into a great panic and nervous state on May 18, 1910 before its flying past t...
