Analysis on The Impact of The Feed Way in Coal Technology over Condensing of Cycle Time;

When the coal winning machine one-way cut coal,cycle time is short,cutting drum web is big,starting up ratio is high,every processes tight connect,working face is safety,to be good for the coal winning machine.

Microbial morphology and size distribution of aerobic granules were analyzed under cycle time of 4 h and 12 h.

In an 6 L internal-loop air-lift reactor with carrier particles for immobilized enzymeas the solid phase, the effect of aeration rate, particle size and solid content on mixing timeand circulation time of liquid were investigated.

The distributions of circulation time were obtained by means of a single suspend bead for sixteen types of helical screw impellers with a draught tube in the laminar regime.

According to the factors that affect the speed of the transportation vehicles,A rational model of circulation time of transportation vehicles was designed with the methods of queuing theory and numerical modeling.

The seemingly fragmented parts,especially the past and present are closely connected into a whole unforgettable and intriguing story by the construction of the cyclical time.

The aim of this work is to propose an effective method for the solution of the cyclic scheduling problem of boiler system with decaying performance.

The circulating time concept,based on "the individual life experience" held in ancient China,was the basic way that Zhang Ailing knew the world and explained the life.
