Han Fu and his group selected domestic waste newspaper as object and researched 9 factors which affect deinking effect, including pulp content, repulping time, composite deinking agent, mass fraction of deinking agent, curing time, curing temperature, flotation concentration, flotation temperature and flotation time, optimizing the deinking technological condition, establishing a clear process which has an excellent deinking effect and reducing the cost, also the paper has high whiteness and yield rate [11].
Flotation cell is the core equipment of deinking production, so a large number of researches are about improving the structure and property of flotation cell.
Deinking agent should have properties[13]: (1) Contributes to easing and deinking waste paper, does not produce the re-adsorption after deinking and helps to remove the separated ink. (2) Reduces the carbon content of waste paper pulp, improves whiteness, removes carbon particle successfully along with bubbles during flotation decontamination. (3) Does not affect pulp yield rate and mechanical adaptability, plays a good role in wastewater treatment.
Secondary fiber is the dominant factor which affects deinking performance of waste paper recycling; therefore, it should be given full attention to produce high quality deinking agents and choose a suitable deinking technology [16].

According to mechanical theory,the theoretical output speed is 73.9845rad / s.
The conclusion above can be proven through the analysis on uneven factor of load-distribution in the literature [6].
So a main reason for affecting contact stress of gears is the random load torque caused by the road roughness.
The research method is the early exploration for seeking a new dynamic design method which is synthetically considered a number of performances of the gear system, such as the overall dynamic properties, strength and bearing capacity, etc.
