produce advance
2.In this Paper , Firstly, we introduced the produce and the advance and the theory of stability about differential system ,the main contents of this dissertation include: the stability analysis of cellular neural networks (CNN) with delays, and the stability analysis for a class of generalized CNN with constant delays. and the asymptotic stability and exponential stability of Hopfiled neural networks (HNN).
6.Of these various elements is composed the Distributing Class, whose agency is supplementary to that of the Producing Class: and the produce so distributed, or its price, is the source from which the distributors are remunerated for their exertions, and for the abstinence which enabled them to advance the funds needful for the business of distribution.
9.Due to the progress, the catalyst can advance MFR and density of production, broaden MWD , Titanium-group catalyst is one kind of high-activation catalyst, It is used in the ethylene copolymerization system ,and can produce resin whose molecular weight distributing is cabined within the very broad molecular weight range. So that it has substituted some low-activation catalyst one by one, and the production efficiency has been advanced 50%.
