This reduction is rapid, for low grinding forces, and slow for high grinding forces.
Fig.3 The relationship between grinding force and surface roughness The reduction of surface roughness is directly related to the number of active grains Ng and the shape of the grains.
From the above data, it has revealed that the relationship between surface roughness and grinding time is close.

This system includes following parts: series sensors, data acquisition system SQlab III with 36-channels, binaural signal sampling software HEAD Recorder, and analysis software Artemis9.

The reduction of surface tension made sands can be well coated with modified sodium silicate, and the adhesive fill with the sand void.
The thermal expansion and shrinkage of [SiO4] are also different from [PO4], the thermal expansion coefficient(α) of the vitreous formed by sodium silicate is 13.46×10 -7/℃, that of ZY is 89×10-7/°C [10,11], due to a great difference, interpenetration network structure formed in hardening process can easily break under calcination of high-temperature and cooling, and the adhesive film coated on the sand surface was damaged, leading to the great reduction of the residual strength of high temperature and improvement of collapsibility of molding sand.

All data shown in this paper was measured at 5 K with the proton current at MLF of 100 kW or 200 kW.
Such a large reduction of moment size by only 10% hole-doping is hard to explain [1].
Possible explanation for the large reduction of intensity is that additional intensity exists in the much higher energy region, and/or that the broadly distributed intensity in the momentum space makes the evaluation of real magnetic signal with separating from the background difficult, leading the underestimation of the intensity.

Flowchart for the processing of the pregnant solution The coefficient of determination (R2) in both cases was more than 0.98, which indicates a good fitting of experimental data with the obtained equations.

The reduction of Fe(III) to Fe(II) with cellulose, Can.

In hammer peening, the weld profile is modified due to removal or reduction of minute crack-like flaws; compressive residual stresses are also induced by repeated hammering of the weld toe region with blunt-nosed chisel.
Fig. 4 shows the statistical characteristics of the ρ and θ by plotting the measured data in a cumulative probability paper.
It can be seen that the fatigue life calculated is similar to that of experimental results, which gives a possibility to predict analytically a fatigue life for HP specimens with the measured data for the bead shape and residual stress.

The substitution of chromium by manganese leads to an increased hardness (+50 HV10) and a reduction of the critical cooling speed from 19 K s−1 for the reference alloys to 9 K s−1 for the new alloy and a nearly constant hardness of (600 HV10) after Jominy­test.

Under the same condition, the thermal dispersion coefficient of a circular particle model is maximum, and it increases with the rise of Ped number; with the increase of the porosity or the reduction of Darcy velocity, the thermal dispersion coefficient reduces increasingly.
Dimensionless turbulent kinetic energies of different models are verified to confirm the accuracy of models and simulated data in this paper and ensure the reliability and feasibility of data.

By calculating indicator diagram or processing the data of actual indicator diagram, a set of data can be output with every 10 degrees crankshaft angle.
Running steps are 288, and loading the gas pressure of the engine at piston’s barycenter with spline data function.

The adsorption kinetics was studied with the experimental data.
The data were fitted with the pseudo -first order and pseudo-second order kinetic model of Lagergren respectively.
The degradation kinetics of the three pyrethroids in coastal sediments were studied with the experimental data(Table 2).
Therefore, it could be speculated that the degradation of pyrethriod in coastal sediments is reduction reaction, and the possible pathway is shown in Fig.4(with fenpropathrin as sample): Fig.4 The possible anoxic degradation pathway of fenpropathrin in coastal sediment That is, pyrethroids are hydrolyzed at ester bond firstly, and then lose electrons to become m- phenoxyphenyl-acetonitril.
