The reduction of the buffer distance improves celerity of the system; the practice of the PID controller based on BP network obtains better effect under condition of buffer distance of =L 60 mm.

For the data obtained with capillary filter, there is an almost−linear initial sharp decrease in the residual moisture with increasing pressure, and then the curves level off, approaching the asymptotic value above the air-flow regime.
The residual saturation of filter cakes in this no-air-breakthrough regime depends on the reduction of the capillary liquid level inside the filter cake, since the filter medium should also be fully saturated with liquid.

≥ 300 Figure. 2 Standard test cube Results and Analyses According to the data collected in the experiment, the bond stress (kN) of plain bar and deformed bar related to the slippage ( mµ ) is draw in Figure.3 and Figure.4, where y-axis represents the bond stress and x-axis is the bar slippage value. 0 10 20 30 40 50 60 70 0 2000 4000 6000 SLIPPAGE（μm） LOAD（KN） C40SL0 C40SL20 C40SL30 0 50 100 150 200 250 300 0 1000 2000 3000 4000 5000 6000 SLIPPAGE/μm LOAD/KN C40S0 C40S20 C40S30 Figure. 3 Load-slippage curve of plain bars Figure. 4 Load-slippage curve of deformed bars Bond Strength Analysis Bond stress of each specimen with different load level is calculated by formula (1), and the bond stress-slippage curves of plain bar and deformed bar are given in Figure. 5 and 6 respectively.
The bond strength reduction of plain bar is evident, while the deformed bar is less evident; （3）Bond stress between bars and concrete decreases with the increase of slag powder replacement percentage.

Table 2 - Data used in the simulation, considering the isothermal method.
When we look more closely at Figure 5, it appears that due to the increasing flow rate of water injection, there is an increase in the water flow, which can be explained by the reduction of the viscosity of water-oil mixture, thus favoring an increase in its mobility and a difference in pressure between the injection and production wells which result in a greater water shift toward the production wells in the reservoir.

(3) Superoxide anion production: Superoxide anion (O2) was assayed by measuring the superoxide dismutase-inhibiting reduction of equine ferricytochrome C (550 nm).
Data were analyzed by Student's-t test with the level of significance set at 5%.

Pressure The pressure data of the crack initiation and propagation process was experimentally tested, and Figure 3 shows the pressure time curve measured by the sensor.
As shown in the figure, the test pipeline exhibits a clear trend of pressure reduction during the propagation of ductile cracks.

Whereas Fe-TiC composites produced by casting will confront two difficulties: on one hand, the distribution of TiC in the Fe matrix is likely to be uneven because of the density difference between Fe and TiC; on the other hand, the volume fraction of TiC is limited because of reduction of the steel liquid fluidity at high TiC levels.
During the whole heat treatment process in this study, several main reactions may occur: (1) (2) (3) (4) (5) The changes of Gibbs free energy of the above reactions calculated at 200-1800K using thermodynamic data are shown in Fig.1.

A dashpot, represented by c1, is included in the model to introduce the nonlinear roll-off in the force-velocity loops that was observed in the experimental data at low velocities, k0 is present to control the stiffness at large velocities, and x0 is the initial displacement of spring k1 associated with the nominal damper force due to the accumulator.

The digital proofs have bright color, high saturation and excellent reduction of tone.
The proofs of digital proofing used in experiment are got under standardized color management, and the measurement data is good representative.

Apart from grain growth, which results in hardness' reduction, another reason that prevents these crystals from being widely used in IR - optics is their ability to absorb water from the atmosphere [2].
Interplanar distances have been calculated in accordance with the data [5] concerning the crystal structure and the lattice parameters of these compound.
