During thermal exposure, some structural changes such interfacial defect migration, noncontinuous coarsening are easy to occur in the alloy with small grain size/average interlamellar spacing. So the small grain size/average interlamellar spacing is generally disadvantageous to thermal stability of lamellar microstructure.

The signals look like noncontinuous beads on the DNA fiber,which consist of multi-copy and arrange tandemly.Fiber-FISH results with 45S rDNA probe showed that an average signal length is about 3～11μm in many tandem copy sequence(measure number,n=8),so we estimated the size of each copy to be approximately 11～30kb in cotton genome.There are dual signals on each end of the mitosis metaphase chromosomes and pachytene chromosomes hybridized with telomere DNA probe.The signals also look like non-continuous beads on the DNA fiber,the length is about 1～9μm,so we estimated the size is about 4～27kb.The signals almost covered the whole mitosis metaphase chromosomes and pachytene chromosomes of G.arboretum Shixiya 1 hybridized with gDNA probe,the euchromatin zone and heterochromatin zone were identified clearly on pachytene chromosomes,and the signals also look like non-continuous beads.Two BAC clones 150-D-24 and 182-F-9 in DNA BAC library of Pima90 were selected as probe to hybridize with mitosis metaphase chromosomes,pachytene chromosomes and DNA fiber of G.raimondii.
