Cold rolling is widely employed in the manufacturing industry for the production of metal plates. In the cold rolling process, the thickness reduction of the metal plate under the recrystallization temperature generates severe anisotropy; this influences the subsequent forming processes. Therefore, the generation and prediction of metal plate anisotropy during cold rolling is a highly interesting research topic involving upstream studies of sheet metal forming. In this study, using the finite el

3% mepivacaine has quick onset, ideal anesthetic effect and little side effect on cardiovascular system.

In the process of economic circle building of Yunnan central city group,Qujing city has abundant resources,basic resources such as water,soil better combination;relatively more resource per capita,and obvious rich energy resource.These make Qujing play a key role in Yunnan central urban agglomeration development.Qujing is the base of agriculture,energy and chemical industry of Yunnan central city group,it promotes fast,steady,healthy,and efficient development as the engine and the accelerator.At

Yuxi City is rich in resources of solar radiation,from 1960 to 2009,the annual average sunshine hours is 2286.3 hours-2085.3 hours in between,the day average is 6 hours.As many clear days in winter and spring,sunshine is the most abundant during that time.Relatively,it is the least in midsummer because of many rain days.Sunshine is also relatively little in autumn as there are continuous rainy days.The maximum is 8.5 hours day average,and is occurrence in March.The Minimum is in July,and is only

In this paper,the problem of selection to evaluation indexes in Cultivated Land appraisal is discussed,the author also presents the quantification method to those indexes,review can provide scientific dasis for practice.

Using principal component analysis method, the paper makes quantitative analysis and comprehensive assessment of Social-economic Development Status for 39 counties and cities in Qinghai province.The paper also give the results verified with discriminant analysis method and correspondence analysis, and by which the authors provide some development countermeasure for those counties and cities.

Based on dimensional analytic theory and non-dimensionalized thermo-mechanical coupling equations for high energy laser beam irradiation,this paper presents the similarity criterion and the scaling law for thermo-mechanical coupling effect induced by high energy laser beam under some reasonably approximation conditions.The similarity criterion and the scaling law are independent of material properties related to temperature.The finite element analysis models of full scale and scale down pressuri

Based on the probability model of wire corrosion initiation and the probability model of corrosion expansion,the time-dependent failure probability model for a corroded parallel wire cable is established.According to characteristics of a wire-corrosion probability tree formed by probability in each consecutive inspection period,the branch and bound method was introduced to calculate the corrosion probability,solving the key problems of the exponential growth in computational amount.The model par
