In the past research of noise inside the car, vehicle interior noise is mostly passive noise reduction method of vibration damping, sound absorption and sound insulation to reduce, although this method can reduce the noise intensity in the vehicle, but according to noise frequency selective control is difficult, low frequency noise reduction effect is poor, only in the high-frequency broadband noise reduction.
In addition to its low frequency noise control effect is good, effective remedy for the low-frequency noise reduction effect of passive noise control[4].
This system has the advantages of simple realization, good noise reduction effect, the advantages of good operating stability[5][6], so the feed forward controller as the adaptive active noise controller.
The simulation results show that, the FXLMS control algorithm has good noise reduction effect[7].
Using the adaptive active noise control system is designed and constructed in vehicle, in a domestic car uniform steady state operation, noise on the copilot left ear position made active control experiment, and the FFT method analyzes the test data; analysis results show, open the active control system, Sound signals in vehicle noise frequency the main peak frequency that there is obvious attenuation, and then proves that noise selective adaptive active control method in vehicle and control system of independent developing design, the frequency of interior noise cancellation is effective.

Data obtained from the FE model included die-work piece contact pressure, effective stress and strain and material deformation velocity.
The correlation between the calculated and FEA data was obtained in this research.
Also the stress-strain data can be plotted [8].
The peak temperature occurs at the surface of the work piece because of plastic deformation and frictional heating; also it is immediately after the radial reduction zone of the die.
That is because; (1) The material that is heated by dissipative processes in the reduction zone will cool by conduction as the material progresses through the post-reduction zone. (2) Frictional heating is largest in the reduction zone because of the larger values of shear stress in that zone.

Optical data were correlated to engine parameters and exhaust emissions.
All the experimental data were collected using the AVL INDICOM driven by an optical encoder with 0.1 crank angle degree resolution.
BU40 allowed the reduction of smoke at the engine exhaust to zero-like value with a good level of combustion efficiency.
The reduction of pilot-main dwell time increased the OH concentration in the first phase for all the fuels, and increased the difference between them.
This works towards higher NOx liability in agreement with exhaust data.

The data collection is to recognize and calculate the performance of FR.
The required weather data are maximum wind velocity and temperature.
Tolerance calculation Average Avg. error Result Temperature (°C) 27.95 7% 27.95 ± 7% Wind velocity (m/s) 4.63 43% 4.63 ± 43% Data Averaging and Tolerance Data averaging is variable in calculating the spin ratio and other FR calculations after collecting the wind velocity and temperature data.
The calculation will combine all the weather data from any station.
Moreover, the tolerance calculation estimates the error of the weather data.

So forest ecosystem services of the Luan River Basin are approximately calculated by comparing the area of Luan River basin and Hebei Province according to the data of Hebei Province forestry resources.
The services of water purification, Air purification, Climate regulation and Biodiversity conservation could not be evaluated because of the lack of related data.

In the Unitank WWTP, oxidation-reduction potential (ORP) reached the lowest value of -17 mV and the highest value of 130 mV at the end of anoxic/anaerobic stage and aerobic stage, respectively.
In order to achieve the objectives of this study, a full-scale Unitank WWTP in Shanghai was surveyed to collect operational data related to BPR.
The DO and oxidation-reduction potential (ORP) were measured by on-line DO meter and a portable ORP meter (MTC10103, Hach Com., USA), respectively.
Substituting above data to Eq. (3), the theoretical TP variation during anoxic/ anaerobic stage and aerobic stage are shown in Eq. (6)
Fig. 4 Sludge P content of six WWTPs in Shanghai and Jiangsu The sludge P content in the Shidongkou WWTP was 15.4±2.1mgP/gSS, close to the data in WWTP J1 with CAST process.

The data also shows the improvement of crystallinity during the heat treatment process.
Previously collected diffraction data of the carbon soot shows that the main peak of the material coincides with a peak from the HAp material at 28.1˚ 2-theta of MRPD data (indicated by the arrow in Figure 3).
The neutron diffraction data in Figure 3 shows reduction in the height of this peak during the heat-treatment in air between 700 and 800 °C, as the carbon phase is slowly burnt off.
The neutron diffraction data collected from the HIP samples, both pure HAp and a HAp+CNT composite, have been refined using the standard Rietveld profile refinement, where the parameters of a model are fitted to the collected data.
Rietica [3] was the program used to model the diffraction data with the hexagonal hydroxyapatite structure.

To learn about the zero shear viscosity of PCS, the averaging data was obtained based on the transient test data to compliment the steady test data because a long delay time during the steady test affected the zero shear viscosity [6].Even though the normative rheological processes were modeled, the data of dynamic time sweep test method were shown the dissatisfactory repeatability due to temperature change [7].
The data repeatability was examined and referenced to standard of the test reliability.
The shear stress data were automatically recorded by TA Orchestrator, and the axial force data were manually obtained through the screen reading once every 30 s.
The data in Fig. 2 and Fig. 3 confirmed the influences from changing temperature.
Thirdly, the shear stress and axial force data became smoother in Fig. 5a~c.

It had been shown that increasing the copper content in steel and cast iron has led to the reduction of the friction coefficient [1, 5].
It is known that copper does not react with carbon [3], and obtained by chemical analysis data showed that the carbon content in all samples is equal.
There is noticeable reduction of perlite and cupric phase.
If hypereutectoid steel is not alloyed by copper there is no noticeable decrease of wear resistance but there is a reduction of the coefficient of friction.
Data on the coefficient of friction and wear resistance were compared with standard materials used in large heavy-duty friction units, such as anti-friction cast iron and bronze.

Table 1 Sources of data obtained by type of energy supply.
Theyare activity data and emission factors.
Similar data from other countries were used as the last resort.
For countries that do not have local activity data, the IPCC provides data from previous research publications.
Local data have characteristics of a community built into the data.
