In section 3, the vibration reduction effect of the rotating plate in deployable mechanism is verified by finite element simulation.
Several factors are investigated to demonstrate the vibration reduction effectiveness of MREs.
And the simulation results are fairly in agreement with the experimental data.
Then, the vibration reduction effectiveness is verified through numerical simulation of the dynamic rotating system subjected to impact loads.

The nanometer sized Cu2O synhesised this way are highly active for four nitrophenol catalytic reduction.
Which further illustrated that, by nucleation crystallization separation method combines with oxidation reduction method, the particle diameter of nano Cu2O material is smaller.
At the same time, this kind of Cu2O has higher catalytic activity for four nitrophenol catalytic reduction.

It is clear that the effect of water content was little when the water content below 1.0%; and the transit time decreased obviously with the increment of water content when the water content was above 1.0%, and the reduction magnitude of transit time was below 1 %. 
Chen [3] analyzed the influence of water content on concrete ultrasonic-rebound curve based on the total more than 1300 groups of efficient test data acquired from concrete strength measurement.
The varying degree of regression coefficient slope gently turn smooth with the reduction of water cement ratio.
And the degree of reduction is within 1 percent.

Environmental benefits LID mode can produce environmental benefits that traditional rainwater drainage pattern do not have, including the reduction of pollutants, the protection of downstream water resources, the groundwater supplement, the improvement of the ecological habitat quality, the reduction of heat-island-effect in the urban, etc.

But in the course of the study the accuracy of the quantify data needs to be guaranteed, and non-quantifiable environmental benefits and social benefits should be taken into consideration to ensure the fairness of the evaluation results.

For both phases (anatase and P-25) there is a slight shift to the lower energy region and a reduction of the intensity of most of its peaks.
The mode related to the terminal Ti-O bonds, has a high reduction of its intensity and emerges a new vibrational mode around 828 cm-1, which may be related to the formation of nanoparticles of SnO2 on the nanoribbons surface.
The reduction of the absorption bands was accompanied by the displacement of peak, which suggests the formation of other organic compounds and therefore not complete mineralization of the dye.
From the data obtained, it is observed that, in general, the NRTi/P-25 showed a rate constant greater than those exhibited by the nanostructures of anatase (Fig. 3).

From the instrumentation data, it was obtained the loads in the levels for all load increments and the skin friction.
For this reduction to occur in the results, the first loading needs to be carried out until the saturation of the skin friction causing a great displacement of the pile along the shaft.
Another factor that may have influenced the reduction of friction in the second test was the bulging, as we verified that it can, after the end of the first loading, entail a region of the shaft without contact with the soil, as we show in Fig. 3, which would reduce the pile contact area with the ground, thus decreasing the skin friction.
This implies a reduction of the lateral area of approximately .

Ferrous metallurgy gives great importance to reduction of energy consumption, that is why the direct rolling process, comprising charging of hot continuously cast bars directly to the reduction mill (breakdown mill) is an upcoming trend [1,2].
The advantage of the direct rolling technology is reduction of energy and power resources due to decrease [3,4] or avoidance [5-7] of power consumption for heating the bar prior to the rolling.
The model adequacy has been tested on the basis of repeatability of experimental and computation data by means of Fisher, Student's and Mann-Whitney tests [15].

Such properties make VO2 promising to apply in various fields such as “smart windows” for energy saving and comfort [7, 8], electrical-optical switching devices [9, 10], thermal sensors [11], cathode materials for reversible lithium batteries [12], Mott field-effect transistors [13, 14], data storage [15, 16].
The reduction degree of V5+ ions is determined by the contents of oxalic acid dihydrate.
The weight loss is over at 381 ℃ and the exothermic peak at 387 ℃ corresponding to the crystallization temperature of VO2 was not found, in which the reduction of the crystallization temperature of the desired M/R-phase VO2 is favorable.
And it is favorable for the reduction of the crystallization temperature of the desired M/R-phase VO2.

The reduction of in-phase coupling force and the variation of the demodulation phase angle in sense mode are two main error sources for the offset described above.
The phase-frequency characteristic can be expressed by 22 ( ) arctan[ / ( )] sense sense sense senseQ     (5) The squeeze-film air damping coefficient _squeeze yb and the slide-film air damping coefficient _slide yb of sense mode decrease with the reduction of μ, increasing the quality factor ( __ /( ) sense sense squeeze y slide y Qm b b ) and altering the phase-frequency characteristic of sense mode.
All the parameters of a fourth-order gyroscope prototype with coupling forces were obtained using a nonlinear least squares fit method based on the measured data on each vacuum degree.
Therefore, the influence of the drift of in-phase coupling force from drive mode can be ignored and decreases with the reduction of air pressure.

The geometrical dimension data are listed in table 1, the density is taken as 7 g/cm3, 2.3 g/cm3, and 0.98 g/cm3 for alloy, glass and nitrile rubber respectively.
condition of the same alloy core content in the composite. 3.2 Effect of microwires diameters on the microwave permittivity Fig. 5 Complex permittivity of randomly oriented Co-rich microwires of 3 mm in length and 5% in mass content in composite versus frequency (with volume content ratio being 1: 1.17: 1.06, total length ratio being 6.69: 2.26: 1 for C1, C2 and C3 respectively) Fig. 6 Complex permittivity of composites with randomly oriented Fe-rich microwires of 3 mm in length and 30% in mass content in composite versus frequency (with volume content ratio being 1: 2.98: 4.78, total length ratio being 13.78: 7.42: 1 for S1, S2 and S6 respectively) As can be seen from the 2 figures of complex permittivity of the randomly oriented microwires at the microwave frequency shown above, the increase of the skin effect with the thicker diameter of the microwires results in the decrease of the effective volume content of the microwires samples in the composite, further cause the reduction
As can be seen from Fig. 5-6, the smaller diameter of the microwires, the greater reduction of the permittivity of the randomly oriented glass-coated microwires composite with the increase of the frequency, showing very good frequency disperses properties.
The real part of the permittivity shows small reduction with the increase of the frequency, and some high frequency electric dipole resonance peaks for the circularly oriented Fe-rich microwires.
