final method
2.Based on actual data, emphasizing particularly on the course of consolidation and deformation of preloading method combing vacuum with stack-load, the paper illustrates the mechanism of deformation of pre loading method combing vacuum with stack-load from consolidation and final effect, and calculates final settlement by delamination summation-method and hyperbola method, presenting relative parameters used for designing and execution control.
3.The paper discusses the effect of using quantity of chemical, its composition,AQ using quantity and booking time for degree of cooking and quantity of final pulp in AS-AQ method cooking hemi-chemical wood pulp, Optimum technique condition of producing boxboard pulp are optimized and determined, The paper contrasts and analyses the economical cost between AS-AQ method AS method and AS-AQ method is of better economical benefit.
10.In this paper,a simulation experiment of precision forging hollow straight spur gear with a boss was done,and deformation of the final stage of precision forging was emphasised To analyse by coordinate grid method. The law of metal flow was obtained,and the conclusion proposed can be referred to working out the process of precision forging.
