opening speed
6.With the great ambition of “developing three ports and constructing three towns” in mind, Sanmen is vigorously implementing the strategy of “industrialization, urbanization, integration of city and countryside”, and is carrying out the four actions of “building up large frame, cultivating huge industry, opening up more areas and optimizing the overall environment.” Sanmen will expedite the developing speed of advanced manufacturing industry and promote the harmonious and sustainable development of the society and the comprehensive development of people.
7.The relation between impurity amount of card sliver and cylinder speed, licker in speed and delivery speed of C4 carding machine is discussed, and the influences of the Rieter Mono stream opening machine, Aerofeed feeder and domestic A092AST hopper feeder on impurity amount of semi finished products should be given a further study.
8.By decomposing the Dirac function on the orthogonal basis and comparing with the basic functions, the explicit expression of Green?s function is obtained. The integral equation with the crack opening displacement as an unknown is derived and the scattering displacement is calculated. Examples show that such a scattering problem can be solved by BEM with satisfactory accuracy and at fairly high speed.
9.The econometric results show that (1) The urban development in China have a trend of convergence, the larger the size of a city, the lower the population growth rate; (2) The inertia of migration encourages urban population growth; (3) The opening-up policy significantly favors urban development, and such effect is particularly significant in relatively backward inland areas; (4) The infrastructure development has a significant impact on the speed of urban population growth.
10.According to high short fiber content and many neps & impurities in cotton assorting of C 14.6 tex yarn, technology measures of suitable increasing beater speed and secondary air & reforming in beater room are adopted combining with specificity of opening-blowing unit. The measures can increase clean efficiency of opening-blowing process, and cleaning efficiency is increasing from 34.70 percent to 62.33 percent, so cotton lap is confined.
