narrow segment
1.Atherosclerotic area(mm 2) and luminal narrow per segment were quantified on Leica Imaging System. Results: In 484 segments, the CAC incidence, calcium area and calcium score(0,0,0) of segments without atherosclerosis were lower than those with atherosclerosis(28%, 1.74 and 6.73, P<0.01) and these with≥ 75% stenosis(54.4%, 5.8 and 22.7,P<0.01);
5.Applying the result to the model of multiple segments of the CDW, the exponential law of the conductivity and the threshold of applied field, as well as the “narrow-band" noise are obtained simply, which are consistent with the experimental formula. To describe the connection of a multiple segment of CDW system, the mechanism of “elastic connection" is treated as an internal force, which clarifies the vagueness in primary Portis model.
