Under such circumstances, detour, as the embodiment of personal literary view, is proposed in this paper: I would rather experience the pain of dilemma which intellectuals experience when they are writing than hesitate over the affirmation of literary works value.

This study evaluated the recycling potential of bagasse CEH and DQP bleached pulps.

The process included separating DNS crystal directly from the reaction-finished reactants by cooling instead of neutralizing, and then recycling the alkaline mother liquid to the next oxidation process.

Papermaking wastewater produced by recycled paper was treated through flotation adding SBR bio-treating.

The relation of pressure balance must be kept properly in a circulation loop for keeping a fluidized-bed unit in working order.

Based on the analysis of pressure drop of circulation loop on circulating fluidized bed boiler, the pressure drops relations of main bed, separator, standpipe, horizontal orifice of loop seal, transport chamber of loop seal and inclined pipe are developed.

Particles are added to the riser at both the bottom and the middle positions, and two solids circulating loops named main-loop and sub-loop are formed.

Combining numerical computing method,the overall process dynamic mathematical model of the circulating loop in a circulating fluidized bed boiler (CFBB) is solved.

Based on operation and hydrodynamic characteristics of every parts of the circulating loop and the pressure balance property,an overall process dynamic mathematical model of circulating loop in a circulating fluidized bed boiler,suiting for wide sizing of bed material,is established.
