r-strategy
3.Methods Three pre-selection formulae(NAL-R, Berger, one third) of prescriptive strategy have been applied to the children(15 subjects, 30 ears) with sensorineural deafness who sustain severe and profound hearing loss, meanwhile, the comparison has been made at several frequencies in different aspects such as target gain,real ear insertion gain,unaided/aided threshold and so on.
5.Finally it describes the integration of existing index algorithms (packed R-tree,Quad-tree and Buddy-tree),and advances the application theme-oriented index strategy.
6.Based on the Resource Dependence Perspective and Resourse-based View, the traditional model of the determinants of new venture performance NVP＝f（E，IS，S）is extended to NVP＝f（E，IS，S，R） by the introduction of entrepreneurial resource as a new determinant, where NVP represents new venture performance, E represents entrepreneur (team), IS represents industry structure, S represents strategy, and R represents resource.
9.By using the row action method and the dividing?conquering strategy, this paper puts forward an iterative dividing?conquering algorithm to solve arbitrary systems of linear algebraic equations ?AX=b(A∈R??n×m?)?. It is proved that the algorithm is convergent for arbitrary consistent systems of linear algebraic equation. The acceleration techniques of the algorithm and its prospective application to MIMD parallel iterative algorithm for the system of linear algebraic equations are discussed.
