It was pointed out that the main problem of exploring an indefinite systems’ optimum lies in the lack of non optimum analysis on the system. The syndrome and empirical analysis based on the non optimum category of the system were established. At the same time, the non optimum measurement of the system along with non optimum tracing and self organization of the systems was also put forward.展开更多

The sensitivity expression of system reliability index and the safety margins were presented in the stochastic structure systems. The optimum vector method was given. First, the expressions of the reliability index of the safety margins with the improved first-order second-moment and the stochastic finite element method were deduced, and then the expressions of the systemic failure probability by probabilistic network evaluation technique（PNET） method were obtained. After derivation calculus ,the expressions of the sensitivity analysis for the system reliability were obtained. Moreover, the optimum design with the optimum vector algorithm was undertaken. In the optimum iterative procedure, the gradient step and the optimum vector step were adopted to calculate. At the last, a numerical example was provided to illustrate that the method is efficient in the calculation, stably converges and fits the application in engineering.展开更多

Orthogonal test was used to screen the optimum combination of four factors including sesame residue concentration, pre-extraction pH value, potassium chloride concentration and reverse extraction time. The yield of extracted sesame residue proteins was the indicator to evaluate the efficiency of process. E Result1 The optimum extraction conditions are as follows： sesame residue concentration： 0.06 g/ml; pre-extraction pH value, 3.0; potassium chloride concentration, 1.5 mol/L; and reverse extraction time, 20 min. In the optimum extraction conditions, the extraction rate was up to 86%. [ Coaclusion] Extraction of sesame residue proteins can be well performed with AOT/isooctane reverse micellar system.展开更多

Theoretically, each industry can become a strategic industrydepending on strategic task, goal of a given economic development stage and nationalor regional conditions. So, establishing strategic industrial system, as output of thedevelopment of social labour division, is of great significance in both constructing national or regional industrial structure and making out national regional industrial policy. In this paper, the authors made a detailed study on China's strategic industrialsystem by using Weaver--Thomas Model.展开更多
