In cantilever beam system, through the experimental method to study vibration reduction mechanism of particle collision damper.
Damper is fixed to the cantilever beam free end, acceleration sensor is fixed opposite the damper, the vibration signal is given feedback to data acquisition analyzer through the charge amplifier, the analyzed data transports to the computer software DASP(Data Acquisition & Signal Processing), can get the vibration frequency domain and time domain figure of the cantilever bean system, adjust the frequency to resonant frequency that makes the maximum amplitude of the cantilever beam.

Although the mass of the impacters is same, the vibration reduction effect is not obviously as the impacters diameter changes.
The aluminum filling rate is 40%, the impacters’ mass are same, but the vibration reduction effect is absolutely different.

Nevertheless, they suffered from sluggish kinetics of the oxygen reduction reaction (ORR).
In addition, a weak peak from the (1(_)11) plane of copper oxides was observed at about 35.5o in the XRD data, suggesting that part of the copper has not been completely reduced and a very small amount of copper oxides exists.
The earlier the oxygen reduction peak appears, the higher the electrocatalytic activity of the material.
Methanol is oxidized at the anode concomitant with oxygen reduction at the cathode.
Sun, FePt nanoparticles assembled on graphene as enhanced catalyst for oxygen reduction reaction, J.

This was attributed to difficulty in estimating the mean rolling temperature from the available data.
The required input data are rolling speed, roll radius, furnace temperature, initial and final height of the specimen, and specimen width.
From the output of the program, the temperature distribution, yield stress validation, rolling load and torque distribution across the thickness of the rolled specimen at different pass reduction are evident. 2.5 Experimental Data used in validating the new hot rolling simulation was obtained through preliminary metallographic, hot torsion tests, and hot rolling experiments performed on the as-received wrought AISI316 with inclusions of Nb, V and Ti in the temperature range (600 – 1200) 0C and strain rate range of 3.6 X 10-3s-1 to 1.4s-1.
The program made use of experimental and theoretical data from a study of loads and torques for light reduction in hot flat rolling at strain rates carried out by [2] and the results from the reverse sandwich effects in HCSS316 hot flat rolled at low strain rates and low reductions investigated by [13] as input data.
(c) The ratio of experimental to calculated Torque based on RMS mean rolling temperature on mill A was high about 1.17 at low reductions (5%) and low about 0.91 at higher reduction

Abstract.This paper investigated the reduction of benzo[a]pyrene (BaP) in coal tar pitch by modifying with 1,4-Benzenedimethanol, Divinylbenzene and Trioxymethylene.
Results and Discussion The data on reduction of BaP with 1,4-Benzenedimethanol were shown in figure 1 and figure 2 .
Figure 1 Reduction of BaP with 20% 1,4-Benzenedimethanol at various temperature Figure 2 Reduction of BaP with 1,4-Benzenedimethanol of various content at 120℃ The experimental data on conversion of BaP with divinylbenzene in both case, respectively of heating temperature and divinylbenzene content, were shown in figure 3 and figure 4.
Figure 3 Reduction of BaP with 12% divinylbenzene at various temperatures Figure 4 Reduction of BaP with divinylbenzene of various content at 130℃ The both BaP decreasing rate and converting rate are firstly increasing and then decreasing in both cases.
It is also evident from the results that these crossing link monomers bring about the reduction in the following order: Trioxymethylene> 1,4-Benzenedimethanol > Divinylbenzene.

This paper focuses on a new method of aerodynamic drag reduction.
This conclusion will have profound guiding significance in the aerodynamic shape designing and the aerodynamic drag reduction of an automobile.

CFD method is efficient and cost saving, and besides, it can simulate the condition and obtain the data which experiment cannot [6].
Drag Reduction Based on Isobaric Surface The simulation of flow field around an automobile has much similarity with a pipe flow.
