The results show that demulsifier concentration is an important factor in controlling the dilational properties of adsorption layer.
The stability of these films is mainly determined by two factors: one is the mechanical strength of the film; the other is the rheological properties of liquid–liquid films.
Rheological properties are mainly characteristics of dynamic film properties.
The working principle is similar to that of Lucassen and Giles. [7] Results and discussion Dilational rheological properties are the main characteristics of the dynamic properties of a film.
General speaking, an increase in the demulsifier bulk concentration can affect the interfacial dilational viscoelasticity in two aspects, the effect of two opposite factors, causing the dilational elasticity reaches a maximum value with the increasing concentration[11].

Therefore, the impact of UV radiation on the properties of textiles, food, or other products during production also varies greatly.
These changes can affect other physical properties of textile materials, such as color and mechanical strength, when produced and used by traditional methods.
To study the influence of solar UV rays on the properties of processed products, it is essential to determine the dose of UV rays exposed during the technological process as objectively and reproducibly as possible.
The measuring device is battery-powered, can operate in outdoor testing environments, with little vibration when exposed to wind or other mechanical factors.

Introduction PEM is the key technical material of fuel cell[1].What’s more,it’s the heart of the cell,whose  performance directly affects the performance of fuel cell operation.Aiming at the characteristics of PEM,this paper reviews the basic properties and research progress. 1 The basic properties of proton exchange membrane The proton exchange membrane(PEM) is the key part of PEM fuel cell.
Fig.1 The classification of membranes The performance of PEM can not only affect cell performance directly,but also be vitally important to reduce the cost and internal resistance of the cell, and improve the energy conversion efficiency[2].Therefore,PEM should meet the following conditions[3]:(1) high proton conductivity,(2) low electron conductivity,(3) low permeability to fuel and oxidant,(4) thermal, chemical, oxidative, and hydrolytic stability,(5) desirable mechanical properties in both the dry and hydrated states,(6) cost, and(7) capability for fabrication into membrane electrode assemblies (MEAs).
It can be seen from Table 1,these partial fluorizated membranes will be superior to the Nafion membrane in the mechanical strength, thermal stability, proton conductivity and methanol permeability,as well as the prices.However, many properties is not optimal due to materials limitations.

The chance to control the mechanical properties by controlling the balance of α" and β phases is only one of the advantages that has been observed in the TiNbSn alloys.
The cryogenic treatment has already shown to be effective to increase the mechanical properties of NiTi alloy by martensitic transformation [27].

If dissolution of metals takes the essential role in the stress corrosion cracking concerned, cracking susceptibility is expected to be significantly affected by dielectric constant of water.
The cracking has been caused by sensitization in welding heat affected zones due to Cr depletion along grain boundaries [1].
To solve the SCC problem, a great number of studies about SCC mechanism on stainless steels in high temperature water have been done from the points of view of material, mechanical, and environment [2].
However, there have been no studies about SCC mechanism focusing on physical property of water.
