Using the correlation between the radiance or Doppler velocity and the extrapolated magnetic field, we determined the emission heights of a set of solar transition region lines in an equatorial coronal hole and in the surrounding quiet Sun region. We found that for all of the six lower-transition-region lines, the emission height is about 4-5 Mm in the equatorial coronal hole, and around 2.Mm in the quiet Sun region. This result confirms the previous findings that plasma with different temperature can coexist at the same layer of transition region. In the quiet Sun region, the emission height of the upper-transition-region line Ne VIII is almost the same that of the lower-transition-region line, but in the coronal hole, it is twice as high. This difference reveals that the outflow of Ne VIII is a signature of solar wind in the coronal hole and is just a mass supply to the large loops in the quiet Sun.

After revisiting models for the ferroelectric relaxors,we notice that the models can be classified into two *** group models are directly based upon the compositional fluctuations,such as Smolenskii’s theory and SRBRF *** other models are experimental phenomenon oriented,such as macro-micro domain crossover and superparaelectric state. The later explanations imply that the ferroelectric relaxor is in a critical *** unusual field induced phase transition in ferroelectric relaxor also suggests that this is a critical phenomenon with first order phase transition *** within the framework of effective field approach and with introducing the concept of quantum temperature scale,we reproduce the diffused phase transition of the dielectric constant and the field induced phase *** seems that the larger quantum fluctuation at low temperature depresses the ferroelectricity in ferroelectric relaxors,and results in their unusual physical properties.
