The direct reduction in carbon-based pellets has been studied extensively[2].
However, the model research on thermal processes in RHF for direct reduction is still to be further developed[4].
The carbon monoxide is the main product of the direct reduction by carbon due to the gasification of carbon.
The boundary condition is calculated according to design parameter, experimental data and field data.

Sampling and processing of experimental data.
The segments of experimental data sample including the whole test line.
Acquisition and processing of experimental data depends on MAC system, the sampling time of each segment is 6s, and it will output the maximum of derailment coefficient, rate of wheel load reduction and lateral force of wheel axle of each piece of data after calculating.
This paper will use the 3σ principle[4] of normal distribution, namely, using the mean value of the sample data plus 3 times of the mean square deviation, then we will get the inferred maximum of sample data and take this number as the maximum of experiment data may achieve.
Then, we take each radius or radius interval data collected in accordance with the velocity level classification as a small sample, and through mathematical statistics analysis of original data, we are able to determine that each radius interval for each velocity level data showed a normal distribution law.

The reduction process of laterite nickel ore is affected by the reduction potential or ratio of CO and CO2, with higher CO the higher reduction process takes places [4].
The reduction temperature and reduction time significantly affect the development of Ni and Fe particles.
The data of lateritic nickel ore composition was shown in Table 1.
Comparison of pore size to Ni content of the product Reducing agents Pore size (Angstrom) Ni content in the product (%) Coal 9.4 5.75 Coconut shell charcoal 33 8.54 Green Coke 60-100 15.23 To support pore size data, bulk density testing was performed on all three types of reducing agents.
With the reduction of Fe2O3 to Fe will increase the Fe content in the reduction.

Through calculation and test, we can determine the maximum air pressure and air volume needed by the device with reference to the testing data of similar systems.
Concerning the measurement error of the measured data and the change of the device’s performance, the actual air pressure and air volume can be acquired as follows: Q = (1.05~1.10)Q0; P = (1.00~1.15 )P0.
As far as energy conservation is concerned, it is appreciated to calculate the air pressure and air volume in need as accurately as possible, and limit the error between the calculated data and the actual running value within 10%.
The data in Table 1 is the analysis and comparison of the fixed speed motor, the multispeed motor and the variable-frequency motor.

Mean residual stress values of simulation after compression are identical to the XRD testing data.
Fig.5 Mean residual stresses of simulation values and XRD testing data along z-locus Fig.5 shows mean residual stress comparison of simulation values and XRD testing data after compression of Plate B along z-locus.
And the average error of mean residual stresses between experimental data and simulation values is 24.3MPa.
Obviously, it can be seen that mean residual stress values of simulation after compression are identical to the XRD testing data.
Mean residual stress values of simulation after compression are identical to the XRD testing data.

It's significantly meaningful to the final completion of the target of CO2 emission reduction in China to study the potential of CO2 emission reduction expected in the next 10 years of China's construction development with the status quo.
Energy-efficiency and material-saving in construction are the two main subjects in CO2 emission reduction in China, which are the main objects of the study for the potential of CO2 emission reduction in China's construction.

It only changed a parameter that needs to be studied every time by control variable method, and studies its influence on vibration reduction.
After collection of vibration signal is finished, the collected experimental data are conducted.
