Abstract： In order to gain a better performance and reduce the computational complexity of the filter design in the underwater acoustic single car rier system, a new Iterative Block DFE （IBDFE） is proposed, which operates iteratively on blocks of the received signal, and fully implements its filtering operations by Discrete Fourier Trans forms （DFTs）. Two design methods are consid ered for IBDFE： one is HDIBDFE, and the oth er is SDIBDFE. In this paper, the first one is a dopted. In this scheme,

＜正＞For the complexity of ladle furnace refining production process,it’s impossible to establish accurate mathematical prediction model for element yield rate that is an important parameter in the process of alloy adding. Model selection is the key factor of better element yield rate *** this paper,feed-forward neural networks （FNN） and support vector machine（SVM） are chosen as candidate modeling *** introduce that,under certain condition,FNN and SVM can be transformed into each *** an analysis of the essential difference between two algorithms is carried *** element yield rate prediction models were set up using different FNN and *** comparison results show that modeling by 8-SVR can meet the production requirements and has better prediction accuracy than by FNN.

It has been demonstrated that the olfactory bulb(OB)is the sole target for neuroblasts originated from the subventricular zone(SVZ).In order to explore the effects of the OB on the neurogenesis in the SVZ and rostral migratory stream(RMS)in adult mammals,a surgical removal of the OB was performed in the *** Nissl staining and immunobistochemistry for showing glial fibrillary acidic protein(GFAP),bromodeoxyuridine(BrdU),and polysialylated neural cell adhesion molecule(PSA-NCAM)were done in the brain tissue from adult SD rats in different survival times after removal of the OB and in the sham *** sections were observed under light-microscopy,and the Leica DM LA image analysis system Qwin software and SPSS statistic analysis software were used to estimate the cell number and *** addition,the ultrastructurai characteristics of the cells in the SVZ and RMS were observed under *** results showed that the cell number in the RMS increased after OB removal,and this was from an increase of PSA-NCAM- and GFAP-positive cells at a shorter time after the *** the postoperative delay,increased PSA-NCAM-positive cells became the main sources for accumulations of cells in the *** percentage of BrdU-positive cells decreased in the RMS at the longer survival and more apparently in the rostral part of the *** differentiated cells that were like mature neurons appeared in the RMS in the site of bulb *** results in present study suggest that the production and migration of the cells characterized with neuroblasts along the RMS,as well as the differentiation of those cells in the SVZ do not seem to be affected by OB removal,although the cellular proliferation is *** increase of the astrocytes after the surgical removal does not seem to be related with promotion of neurogenesis *** can be concluded that the OB is not apparently essential for neurogenesis in the SVZ.
