In this paper, the old newsprint and the common domestic old paper are subjected to deinking process. We mainly studied the relation between deinking efficiency of different recovery pulps and their colloid-chemical behavior such as Zeta potential and surface tension. Technical conditions that affect the deinking pulp’s colloid chemical behavior are also analyzed here.

Coordinated pretreatment of xylanase and laccase on Soda-AQ wheat straw pulp before CEH bleaching was studied. Results show: Pretreatment of xylanase and laccase has better effect than of sole xylanase and sole laccase; Coordination can increase pulp brightness and bleachability, improve pulp filterability of water, lighten degree of effluent pollution in bleaching workshop, and develop overall strength properties of bleached pulp.

The effect of washing temperature, washing stages and the cooking operation on the ethanol pulp had been investigated, and the reason for higher kappa number of the ethanol pulp was discussed. The results preliminarily showed that the dissolved lignin could re-adsorb to fiber surface by means of fiber classification technology and explained the questions found during the study. Some measures were taken to reduce the kappa number, the results had shown that there was obvious absorption in the ethanol pulping; lignin remained in the pulp could easily be dissolved and the pulp with lower kappa number could be obtained at a higher temperature; the kappa number could reduce by increasing washing time; it could enable dissolved lignin to separate out from the ethanol pulp and restrain the lignin absorption by blowing cooking liquid at high temperature.

This thesis has carried on comparative analysis to the power characteristic of 5 kinds of institutional framework of enterprises at first, and has carried on the survey to the domestic and international train of thought in the research about enterprise's power, then puts forward the basic contradiction in enterprises organization ("The contradictions of the complexity of management's target and people's limited reason") and essential feature ofcurrent enterprise's power ("Solidification of power"), and then has put forward new train of thought in the study of enterprise's power and organization ("flow of power"), finally has designed the way and direction that the power flowed in enterprises, Combining enterprise's life cycle theory and American scholar ***'s model about organization development.
