Optimum determination of partial transmission ratios of coupled planetary gearboxes For the low-speed row of the coupled planetary gearbox (see Figure 1), the design equation for the pitting resistance can be written as follows [8]: (1) In the above equations, , , are coefficients which consider the effects of the gear material, contact surface shape, and contact ratio of the first gear unit when calculate the pitting resistance; is the torque of the driving shaft (Nm), is allowable contact stresses of the low-speed row of the planetary gearbox.

These four methods regard the smoke as a whole and make the measurement, however, O2, CO, CO2 gas in flue gas and Fe, Al, Ca, Mg, S and other materials in fly ash will cause the changes in dielectric constant of fly ash.
The concentration relationship between CO and CO2 Fig. 3.Controlling model of combustion neural network Here, if all feeders are regarded as feeding equivalent materials we can see the amount of coal delivery as a parameter.
