Figure 1 : Dynamometer drive train - schematic Analysis method The displacement data from the transducers was analysed in three stages: Stage 1: A fast Fourier transform was produced for each data channel for frequencies up to 8 kHz.
The data used for analysis was a very short time period, about twenty squeal frequency cycles of data.
Wave progression Figure 2 : Determination of a forward travelling wave from recorded data Figure 3 : Determination of a standing wave from recorded data Parameter determination Travelling waves.
The information known from the recorded data is the value of w, j, � and �.
If a value of �j is assumed, a least squares analysis of the data can give the values of A, B, � and � from Eq. 1.

Suggested scanning lines and data export.
After selecting the scanning lines, in the next stage the measurement data were exported.
This step was conducted by using the Data export command (Fig. 17).
The export of the measurement data may be carried out to two data exchange file formats, i.e. .txt and .para.
The example of measurement data exported to the .para file is presented in Fig.19.

If the architectural heritage cannot be effectively protected, the cultural values will be destroyed and become smaller, which will lead to the reduction of the economic value and social value.
The reduction of the economic value and social value will be harmful to the protection of the cultural value.
(in Chinese) [6] Modern Chinese Dictionary, Commercial Press (2005) (in Chinese) [7] PRC Cultural Relics Protection Law, Article 2: The State places under its protection the following cultural relics within the boundaries of the Peoples Republic of China:(1)sites of ancient culture, ancient tombs, ancient architectural structures, cave temples, stone carvings and murals that are of historical, artistic or scientific value;　　(2)important modern and contemporary historic sites, material objects and typical buildings that are related to major historical events, revolutionary movements or famous personalities and that are highly memorable or are of great significance for education or for the protection of historical data…(2007) (in Chinese) [8] Zhen Li, Dongxia Lei, Tongji University Journal Social Science Section (2009/10), p.48 (in Chinese) [9] Qinfu Zhu, Productivity Research (2004/08), p.131 (in Chinese)

According to the test specification JTJ052-2000, Marshall compaction specimens are put into the freezer to -10.0°C, and then start the data acquisition system.
But the stiffness modulus presents different reduction along with the increase of the quantity of two kinds of textile fibers.
Its vertical deformation and lateral deformation are also less than AK-13I, reduction of deformation rate is about 10%.

Therefore resource-based regions leave a great potential in energy-saving and emission-reduction.
To sum up,low carbon economic development of resource-based region can reduce China's carbon reduction pressureandbecomes a new path to crack "resource curse"It has important practical significance to build a scientific evaluation index for low carbon economy of resource-based regions to promote the low carbon economicdevelopment.
It collects relative data of three typical resource area of Inner Mongolia, Shan Xi and Hei Longjiang from 2006-2011 to evaluate their economy development and fluctuant trend.

It obtains a significant reduction of the vibration of the mount while the PI controller performs best for the higher frequencies and achieves a reduction of 20dB compared to the passive vibration isolator.
The experimental data also shows that the displacement of the isolation table is reduced at a frequency range lower than 1Hz.

Design principle Polymer damping material is widely used in vibration damping and noise reduction.
The measurement system includes a function generator, a power amplifier, a calibration tube, data acquisition system, and revolver, as shown in Figure 12.
Schematic of the measurement system The experimental results show that, the output voltage of vibration damping packaged MEMS vector hydrophone is obviously reduced than that of original packaged hydrophone, which proves that the application of vibration damping structure surely plays an important role in eliminating interference signal and the design has a certain effect of vibration reduction.

Cytotoxicity assay The cytotoxic potential of the extracts were evaluated in the MTT reduction method [[] T.
Statistical Analysis The cytotoxicity and genotoxicity tests were compared by parametric analysis of variance (ANOVA), using the Student-Newman-Keuls method or the Kruskal-Wallis nonparametrictest, according to the distribution of the data (normality and homogeneity of variance).
This reduction in size allows an increase in the contact surface between the leather waste and reagents improving process efficiency.

United States to lead the world, not only for biodiesel production technology research and standards, reduction of tax, commercial production forefront of the world.
Environmental Protection Agency (EPA), the latest data show that in 2011 the United States produced a total of 908 million gallons of biodiesel exceeds a predetermined production target of 800 million gallons, in accordance with the current pace of development, to the 2013 U.S. biodiesel production is expected to reach 12.8 billion gallons, basically meet the market demand for such energy.
Strong international air transport, aviation industry emission reduction has become the focus of the global response to climate change.

All data on weight and dimension change of wood samples were recorded at each step of the impregnation and cure procedure.
The curve of untreated wood samples showed that the main decomposition occurred at the range between 200℃ and 330℃, resulting in a mass reduction of 55%.
In comparison, the obvious weight loss of composites occurred at temperature between 240 and 320℃, leading to mass reduction of 30%, 24% and 20% at 320℃ for 16.5WPG, 22.8WPG and 30.3WPG, respectively.
