When the content of ABS-g-MAH was 15%, the refinement degree approached to saturation, which should account for the 146% increase of impact strength; the amount of polar groups added during grafting raised, leading to an increasing brittleness and a reduction of relative molecular mass, when the content of ABS-g-MAH exceeds 15%.
According to the Hoffman-Weeks theory [10], the equilibrium melting point () can be determined by linear extrapolation of Tm versus Tc data to intersect the line Tm = Tc.
It should point that Eq correctly represents experimental data only in the case that β is constant and the slope of the curve in the Tm versus Tc plot is approximately equal to 0.5.
Therefore, the melting temperature data corresponding to the lower endotherm are therefore aligned with those obtained when only single melting peak.

The relationship between solid solubility of rare earths in magnesium and crystal structures Crystal structures and atomic radii of magnesium and rare earth elements and relative basic data of magnesium-rare earth alloys are showed in Table 1[6-8].
(3) Solid solubility of rare earth elements in magnesium increases with the reduction of atomic radii (lanthanide contraction).
Table 1 Basic data of magnesium, rare earth elements and Mg-RE alloys Lattice Constant (×10-10 m) Max.

In those techniques, enhanced boiling plays a principal role in our efforts because of its ability to transfer heat with a reduction in size and cost of new units and a decrease in energy-related operating costs.
Practical data, as shown in table 1, indicated that the reboiler allowed the reflux requirement of the column to be met.
Practical data is shown in table 2.
Moreover, practical data cleared that the LMTD(logarithmic mean temperature difference) was lower and the heat transfer coefficient was 88.7% higher than that of the original bare tube heat exchanger.

Table 1 shows the data analysis in determining the optimum PKO-p to MDI ratio.
Three specimens were tested at each exposure time of 7, 14 and 28 days to obtain the average compressive stress and load peak data.
The compressive stress and load peak data were recorded.
Concrete strength increased with reduction in the amount of PU in the mixture.

At present, the powder pressing characteristics research mainly focus on powder metallurgy field, little on autoclaved brick powder, especially the experimental research of the specific production data, which result in the disruption of theory and actual situation.
On the upper, lower beam and the frame are provided with displacement sensors, the two main oil cylinders and two cavities of the stripping cylinder mount pressure sensors, the employment of LabView data card board collection devices with collection frequency set to 100Hz collects the data.
means compressive stress of the upper surface of the adobe, it is a function of h at a reduction height.

The output of the capacitance sensor system is Fourier-transformed by using lock-in amplifiers and recorded as SHO-SNDM data.
One SHO-SNDM data consists of set of the Fourier cos-coefficient and sin-coefficient (n is natural number and notation ‘ex’ means experimental).
By analyzing recorded data sets of (), and ΔCmax are calculated.
We can also observe that peak height decreases with increase of POA level, whose reason is considered to be reduction of trap density by POA.

In order to solve the problem of Diesel natural gas dual fuel engine, such as power reduction, low charging efficiency, the conception of diesel engine fueled with pilot-ignited directly-injected liquefied natural gas is put forward.
Conclusions 1) By analyzing the three groups of simulation data, delaying the injection timing for LNG will reduce the mean pressure peak and the mean temperature peak and increase the amount of NOx emission, but with the postpone of the injection timing for LNG, the indicated power performance becomes worse and worse.

Increasing pore size results in the reduction in its strength.
Such model representative achieved exploring membrane fracture and deformation and their mechanical properties are also comparable to experimental data [7].

TEM results suggested the reduction of mechanical properties of samples was attributed to the coarsening of Ω phase and the precipitation of θ phase during thermal exposure.
After experienced designed exposure process, the specimens were stretched to fracture to get a series of data about residual strength and ductility (i.e. tensile strength, yield strength and elongation).

The introduction of the solution provides a reduction in the setting time of cement without loss of strength both at the initial and at the final stages of hardening.
Results According to the obtained data, the introduction of bacterial inoculum and precursors in a solution of biocarbonization initiators does not affect the water consistency and consistency of the cement paste, regardless of the concentration (Table 1).
