Ⅰ. INTRODUCTIONSince the 60’s of this century, computer technique has been introduced into the field of EEG analysis. Power spectrum, auto and cross correlation coherence, and cumulative analyses on EEG have made significant advances which have greatly attracted the attention of scientists. However, there are little studies in our *** effects of noise on human body are in many ways, and the influence on

Objective To determine the changes of retina nerve fiber thickness with optical coherence tomography(OCT) in Alzheimer’s disease(AD) *** OCT was used to measure the thickness of retinal nerve fiber layer(RNFL) from 38 AD patients and 26 healthy age-matched *** corrected visual acuity and intraocular pressure were measured and the dilated fundus examinations were also performed in those *** Compared with healthy age-matched controls,the RNFL thickness of AD patients(95.40±29.45) were much thinner than the controls(105.91±29.87)(P <().05),especially in superior quadrant,while no difference was found in the other retinal *** Retinal nerve degeneration may be present in the retina of AD patients and this degeneration is likely localized preferentially to the superior quadrant.

A new type of materials, the man-manipulated superlattices, has aroused extensive interest. Earlier we have investisated the electronic structures and physical properties of the perfect superlattices. In this report we propose a possible type of superlattices the incommensurate superlattices. Incommensuration means that the ratio of the superlattice period to the period of the primary crystal is irrational. Because it is very difficult to
