查询词典 distribution function

New multi—objectives function (including mill stand longitudinal stiffness, distribution coefficient of loaded pressure between rolls, weight of mill stand, rolling power, rolls loaded gap profile changeability of bending force, transverse mill stand stiffness of bending force, transverse mill stand stiffness of rolling load) multi—constraints (including rolls strength, spindle strength, backup roll bearing load, minimum rollable gauge, roll surface temperature rise) rolls system parameters optimization model of four—high cold strip mill is established, and programme for mill structural illustration creation on the platform of AutoCad designs is compiled.

The results are listed as follows:(1) In peneplain with plenty water-resource, hexagonal spatial structure of urban system can be formed. Due to differential competed function of central places, the hexagonal system is distorted. The result is that the area covered is decr eased and the girth is unchanged——but every border is usually unequal;(2) A pattern of pentagonal system evolves from hexagonal system controlled by a river;(3) A pattern of quadrilateral develops from hexagonal system under two parallel rivers;(4) The equal distance distribution of central places in narrow geographic space has its special reasons. The results are very important for understanding urban's formation and development and urban plan in Huang-Huai-Hai plain.
