The actuators' mechanical properties evaluation is a fuzzy concept with multiple properties and classes. The fuzzy data quantification, analytic hierarchy process and fuzzy comprehensive evaluation (AHP-FCE) methods are combined to establish the actuators' mechanical properties evaluation (MPE) model. The flowchart of actuators' MPE and selection on AHP-FCE was considered and characterized in detail. The weighted average principle has been taken to replace the maximum membership principle in dealing with the actuator' mechanical properties comprehensive value. One pneumatic actuator and one electric actuator in same working demand are taken as an example to verify the evaluation model. The result shows that it is effective, correct, easy to apply and worth to being recommended in similar evaluation field. © 2011 ACADEMY PUBLISHER.

Negative thermal expansion material of ZrW2O8 and HfW2O8 were successfully synthesized by rapid solidification with CO2 laser. The results of X-ray diffraction and Raman spectroscopic studies show that ZrW2O8 is orthorhombic phase and the strength of the compressive stress is estimated to be around 0.4~0.5 GPa. HfW2O8 was solidified in cubic structure with minor contents of orthorhombic phase and the stress was estimated to be about 0.6 GPa. This was explained by a compressive stress induced during the rapid solidification process due to a sudden drop of temperature from the molten pool to the ambient. Due to the influence of compressive stress, CO2 laser rapid solidification technique is more suitable for the preparation of HfW2O8.

Solid phase crystallization (SPC) of amorphous Silicon(a-Si) films prepared on aluminum-induced textured (AIT) glass was studied. The structure and optical properties of films were studied by virtue of Raman scattering spectra and X-ray diffraction. The results show that the crystalline volume fraction on AIT glass has reached above 80% by rapid-thermal process after 10 h, and it has a better light trapping effect compared with the films prepared on planar glass.

A method for probing refractive index changes in photorefractive crystals using an interferometric technique and digital image processing was proposed. Based on equal thickness interference in LiNbO3 crystal and Fourier transform profilometry, we obtained phase value changes in interferograms induced by a photorefractive effect, and further calculated refractive index changes. The maximal values for extraordinary light (e-light) and ordinary light (o-light) are 6.6×10-4 and 1.2×10-4, respectively.

The enthalpies of dilution of (2S,3R,4R,5R)-hexane-1,2,3,4,5,6-hexol in water and aqueous sodium halide solutions have been determined by isothermal flow-mix microcalorimetry at T = (293.15 to 318.15) K. Experiential equations of apparent enthalpies of dilution varying with the concentration of the polylol have been obtained from the experimental data in terms of the improved McMillan-Mayer theory. Enthalpic interaction coefficients, h2, h 3, and h4, pairwise entropic interaction coefficient s2, and Gibbs free energy pairwise coefficient g2 have been calculated. The values of pairwise enthalpic interaction coefficient, h2, have been discussed in the light of solute-solute and solute-solvent interactions. The results indicate that the values of h 2 show quite well that the straight-line dependence on temperature and pairwise entropic interaction coefficient, s2, is a constant in the experimental range of temperature. © 2010 American Chemical Society.

The phosphorus-doped microcrystalline silicon thin films were deposited by plasma-enhanced chemical vapor deposition(PECVD), the activation energy of thin films were measured by activation energy testing equipment. The activation energy of samples with different doping concentration and different depositing temperature were studied. The results showed that: the activation energy of phosphorus-doped microcrystalline silicon thin films lesser than intrinsic films.The unit of activation energy is meV. Crystalline volume fractions have little influence on activation energy when thin films have a good crystalline volume fraction, impurity effect plays an important role on the conduction.

The enthalpies of dilution of D-sorbitol in water and sodium halide aqueous solutions had been determined by isothermal flow-mix microcalorimetry at 293. 15K.303. 15K, 308. 15K, and 318. 15K. Experiential equations of apparent enthalpies of dilution varying with the concentration of D-sorbitol had been established from the experimental data in terms of the improved McMillan-Mayer theory,and enthalpic interaction coefficients (h2 ,Z3 ,and h4), pairwise entropic interaction coefficient s2 and pairwise Gibbs free energy interaction coefficient g2 obtained. The values of h2 had been discussed in the light of solute-solute and solute-solvent interactions. The results indicated that, the values of h 2 increased as raising temperature in pure water and the sodium halide aqueous solutions; and it shows quite well linear dependence on temperature, so s2 is a constant in the experimental range of temperature.
