The reason may be that the research on the mechanical properties of laminated glass with PVB film has not been conducted in domestic yet, which result in lacking of experimental data to support the material parameters, inaccurate understanding of the mechanical model of the laminated glass and corresponding numerical simulation,
The shear resisting is a main factor affected the performance of PVB film, and there hasn’t experimental research on the shear modulus in China yet.

As the nonlinear efficiency is defined as γ = 2πn2/λAeff, where n2 is the nonlinear refractive index, λ is the operating wavelength and Aeff is the effective mode area, the nonlinearity of PCF can be optimized via the nonlinear refractive index, n2 of the material and the effective mode area, Aeff, which is determined by the fiber structure[2,3,4].
A nonlinear ratio of ~11,000 W−1km−1 has been proposed by utilizing high nonlinear liquid CS2 slot-structure core and high nonlinear bismuth background material [6].

Abstract.
Barra et al [9] reported the influence of the porous material on flame stabilization by numerical method.
They concluded that the material properties of porous media significantly affect the stable operating range.
All the arguments mentioned above were mainly foucsing on the influences of the equivalent ratio, velocities, matrix material on flame shape, location, and stablization.

Due to running in the high temperature and high pressure environment, the security problems become increasingly severe owing to material aging and high temperature creeping damage which was resulted in pipeline leakage or explosion accidents, so the pipeline security monitoring techniques have received more and more attentions.[1] Currently artificial methods are adopted commonly domestically to do the annual inspection for the monitoring of high temperature pressure pipeline, and it has so many disadvantages, such as need stopping production, low efficiency of detecting and poor level of security.

The bed material, in this case - chopped OPF which was loaded on the top of the distributor will swirl due to angular momentum transfer from the hot air.
Material and Method This section discusses the details of the experimental set-up, preparation of the samples (chopped OPF) for batch experiments, measurement and data collection.
The superficial velocity of air was continuously increased until elutriation of material occurs, indicating the maximum operating velocity of the bed.

Introduction
Zinc oxide (ZnO) is well known in the scientific community to possess a lot of advantages in its nature, making it as one of the most prominent material for a variety of electronic and opto-electronic applications [1].
Ga, Al, and In can be used as n-type dopant in ZnO, have been generally recognized to influence the optical and also the electrical properties of the materials [2].Other elements of rare earth group, i.e.
This work is expected to provide the science and research information necessary towards the realization of the new enhanced functionality devices through the integration of photonic, electronic and magnetic properties in a single device that will be beneficial for spin light-emitting diodes (LEDs), novel microprocesses and sensitive biological and chemical sensors.Our motivation on ZnO thin film is, therefore, to examine the structural and optical properties obtained through a feasible, toxic free, chemical solution deposition method by manipulating the Gd doping content.
