INTRODUCTION Polyimide(PI) was one of performance polymers since the mid-twentieth century.This type of polymer in which the main chain consisted of aromatic or heterocyclic rings quickly drew many people attentions because of their good dimensional stability,lower dielectric property,excellent mechanical properties,temperature resistance and resistance to radiation capability1.In 1960s,DuPont firstly developed commercial PI product,named Kapton.From then on,this material has attracted many people to research it and been growing rapidly.At present,PI have been widely used in industries and manufacturing of spaceships and air engines.

Intermittency is a significant component of solar wind turbulence,and appears to be closely connected with the spectral anisotropy of turbulence.We use the Local Intermittency Measure(LIM) to identify
We present statistical findings from a recently compiled catalogue of magnetic clouds observed by the MESSENGER and Venus Express spacecraft. Despite their planetary focus, both spacecraft spent signi
We present a study of statistics of protons and electron properties in the solar wind at 1 AU using new Wind proton and electron data products over more than a solar cycle(1995-2009).
In situ measurements have shown that the less-abundant alpha particles are characterized by temperature anisotropy which could drive the anisotropy-driven kinetic instabilities in the solar wind.
We present an observational analysis of cooling/heating rates of electrons in the expanding solar wind plasma.Our study is based on HELIOS spacecraft dataset ranging from 0.3 to 1 AU in the ecliptic p
