Table 4 show the compressive strength data obtained from the specimens with adding calcined shale as well as the control specimen.
Higher water absorption indicates a larger pore size with a resulting reduction in compressive strength.
The calcined shale retards the setting times due to a reduction in the CaO content; however, the setting times of shale calcined at 800°C and 900°C are close to those of the control mixture. 2.

(3) Application of acrylamide monomer on hemp
The oxidation-reduction system of K2S2O8 and K2SO3 (mass ratio was 1.5 : 1) solution of 6.5 g L−1concentration was as redox initiator with water as solvent, get the hemp fabric treated with cellulase and immerse them in the solution.
The oxidation-reduction system involves creation of different radicals by electron transfer: b.
(4) Color fastness to washing, light and rubbing Data on color fastness to washing, light and rubbing of acrylamide-modified hemp fabrics dyed with lawsone and juglone are presented in Table 3.

When the rice is collected with delay and lower moisture content it affects the amount of whole grains, resulting in the cracking of the grains and quality reduction after drying.
(2) To determine the value of mass diffusion coefficient (D) according to the temperature, was used the Arrhenius equation [7] where the parameters a1 = 1.2609 m2/h and b1 = - 5385.9 (K) were fitted to the experimental data reported by [8].
It is also evident that the drying curve is faster for higher temperatures of the drying air, provides more reduction in the moisture content until it reach the commercial moisture content, optimizing the drying process of rough rice.

By taking the N-shape semiconductor as the example, the actual schottky barrier height arising from the contact of metal and semiconductor is [4]:
Where:
Wm: work function of metal
χs: affinity potential of semiconductor
Eg: width of forbidden band
: neutral energy level of interface state
c : influence degree of interface state on potential barrier height
: potential barrier height reduction caused by image force
When applying the bias voltage V, Emax can be expressed in[4]:
Therefore,
Where:
εi: dielectric coefficient of interface layer
δ: thickness of interface layer
Dis: density of interface layer
Emax : maximum electric field at interface
εs: dielectric coefficient of semiconductor
Nd : impurity concentration
Vbi: Built-in electric potential
In accordance with the relationship formula of the potential barrier height, it can be seen that the displacement effect caused by irradiation makes apparatus’ efficient dosage concentration reduce, the ionizing
The factor to cause apparatus to get breakdown and voltage reduction is: the generation of interface state causes apparatus' efficient schoottky barrier height to reduce, causes the Fermi level pinning position affecting schoottky barrier height to change, and then causes the reverse breakdown voltage to reduce; however the increase of the reverse leakage current may possibly be caused by the deep energy level defect caused by irradiation in material[4,5].
Conclusion On the basis of apparatus irradiation effect analysis and experimental data, the study on the total measuring irradiation of SD ionizing irradiation shows the irradiation generates mainly the ionizing effect; the generation of interface state is the fundamental reason of apparatus’ performance deterioration.

The plates were hot rolled to sheets with a final thickness of 4mm at a reduction of 15-20% per pass at 553K.
Combining with the data analysis result, it could be found that the aging treatment leads to the decomposition of the β-Li phases, but the solid solution treatment can produce more β-Li phases due to the diffusion of Li atom at high temperature.
The results show that the insufficent solid solution strengthening and soft annealing of the investigated alloy leads to the reduction of the tensile strength, while the increasing of the elongation due to the diffusion of the Li atom.

For fear of the experimental data influenced by the shear history memory of oil ,we pre-processing the sample.
So with the increasing of shear rate, apparent viscosity has a significant reduction, and the phase inversion point has a small forward; when the shear rate increased to a certain extent, the moisture content will have no forward any more.
The Reason is that after emulsification, the Active Water and the released water which break away from oil, after that it will together with O/W emulsion realize the main function of viscosity reduction, and the effects of a temperature for this process is small.
