    The fuzzy C-Means (FCM) clustering is widely used in image segmentation,but the random determination of initial clustering centers of the FCM clustering is likely to generate incorrect segmentation of an image.To avoid the such deficiency,a method of choosing initial clustering centers in the FCM clustering for image segmentation is proposed.The method determines the number for the image clustering by means of the number of the peaks in the two-dimensional histogram of an image comprised of gray values of pixels and mean values of their neighborhoods.Then the K-means clustering is used to obtain the initial clustering centers of the FCM clustering for the low-frequency subband image of the original image.The image segmentation experiments show that the proposed method is feasible.

    The genes encoding the outer membrane protein H (OmpH),lipoprotein E (PlpE),type 4 fimbrial subunit protein (PtfA) and fibronectin binding protein (PM1665) were amplified by PCR from genomic DNA of avian Pasteurella multocida P-1059,respectively.The PCR products were cloned into the pMD18-T vector and then sequenced.Sequence analyses showed that the open reading frames (ORFs) of the ompH,plpE,ptfA and pm1665 genes were 1 032,1 008,435 and 348 bp in length,and encoded the 343,335,144 and 115 amino acid residues.Nucleotide sequence homologies of the ompH,plpE,ptfA and pm1665 genes between the P-1059 and the previously reported different serotype strains of P. multocida were 95%~97%,95%~99%,94%~97% and 99%,respectively.In conclusion,the cloned genes encoding the adhesive proteins of avian P. multocida P-1059 will contribute to further study on pathogenesis of this organism.

    The methods in previous literatures were improved based on neoclassical economic theory,and the ratio of the actual total output to the total output under the optimal conditions of capital allocation was used to measure the situation of capital allocation between the industrial sectors of China.Using this method we estimated the capital allocation efficiency in China’s industrial sector.The capital allocation efficiency of China’s manufacturing industry shows a significant volatility,it is closely related to the change of the country’s industrialization process,its value remains at 47.6%~63.8%,and annual average is 55.8%.The current situation of capital allocation is unsatisfactory,and so it needs to be further optimized.

    Lack of non-renewable resources restricts the increase of the traditional economic growth mode.The sustainable production mode of "reduction,reuse,recycling"of recycling economy has been globalized.But the sustainable development of recycling economy faces the disadvantageous risks caused by the constraints of raw material benefit maximization,impetuous investment,repeated investment,inadequate technology innovation and intellectual property protection.In order to promote the effective development of recycling economy,it is necessary to regulate the economic system in every link of the recyling economy industrial chain,govern the enterprise development scale and especially the proportion of heavy chemical industry,to establish incentive resources recycling system,and to form the basic industry of stable renewable resources.It is also important to dig the potential of recycling economy through technological innovation,to control the scale of investment,and integrate the cluster of regional recycling economy enterprises.
