group component
2.Abstract: Changes of group-component, functional groups of carbonyl and sulfoxide and molecular weight distribution of Shengli 100B and South Korea 70 asphalts af ter ageing were investigated by IR spectra and gel permeation chromatograph.
7.Methods Sixty five patients with atrioventricular node reentrant tachycardia (AVNRT) were studied. Compare the value of different target of fractionated electrograms (FEs) (group A, n=25), high-frequency component followed by a low-frequency component (DPs in HL type)(group B, n=20) and low-frequency component followed by a high-frequency component (DPs in LH type)(group C, n=6) for success ablation.
9.Methods 30 cases of vascular dementia were classfied as patient group and 30 normal subjects with corresponding age and sex as a control group, Neuropsychological examination included CCSE, ADAS and the component P 3 of ERPs in patients with vascular dementia was studied by autioddball sequencing and correlative analyses.
10.Metavolcanic rocks in the Baoban Group in the central part of Hainan Island have a Sm-Nd isochron age of 975+8.6 and a U-Pb concordia age of 1401+23 Ma. It is preliminarily considered that the Baoban Group is a flysch volcanic-sedimentary formation of Middle Proterozoic age, which is a component part of Cathaysia.
