To deeply understand the emergence of cooperation in natural,social and economical systems,we present an improved fitness evaluation mechanism with memory in spatial prisoner's dilemma game on regular *** our model,the individual fitness is not only determined by the payoff in the current game round,but also by the payoffs in previous round bins.A tunable parameter,termed as the memory strength(μ),which lies between 0 and 1,is introduced into the model to regulate the ratio of payoffs of current and previous game rounds in the individual fitness *** μ = 0,our model is reduced to the standard prisoner's dilemma game;while μ = 1 represents the case in which the payoff is totally determined by the initial strategies and thus it is far from the realistic *** numerical simulations indicate that the memory effect can substantially promote the evolution of *** μ < 1,the stronger the memory effect,the higher the cooperation level,but μ = 1 leads to a pathological state of cooperation,but can partially enhance the cooperation in the very large temptation *** current results are of great significance for us to account for the role of memory effect during the evolution of cooperation among selfish players.

This paper researched into the delignification mechanism and the relations of black liquor lignin content and alkali concentration to pulping time under the cooking process conditions of wheat straw sodium sulfateanthraquinone(AQ) pulping with Microwave radiation. The results showed that delignification process was divided into two stages: quick stage and slow stage. The lignin removal rate in the first stage was much higher than the second stage, that is, lignin has been removed more sufficiently after quick stage. In this stage, reaction order of delignification was 1.5, and 0.5 with respect to OH-, the activation energy was 51.90 kJ • mol-1. The latter delignification belonged to the first-order reaction and 0.3 with respect to OH-, the activation energy was 72.20 kJ • mol-1KJ. Apparently, slow stage needed to consume large amounts of energy to removal lignin.
