Abstract: With the countries in the world gradually emphasize that the well-controlled of indoor air quality (IAQ) and indoor environment health (IEH) would reduce the hazards of human health. This study response the international community has been launched sorptive building materials, such as standards ISO, JIS, etc in recent years, and based on ISO 16000-23 through the small-scale chamber equipment system to develop and establish “sorptive building material test system, SBMTS”, National Performance Laboratory Center in Taiwan. In accordance with standard operating procedures (SOP) to validation of the test system and provided for sorption test by three building materials. The results was verified SBMTS to conform concentrations of HCHO recovery more than 80% by repeatedly sampling and the system was meet the stability through the instrument monitoring display, which could to provide the relevant performance validation and testing for SBM. This study according results with sorption test of select foreign and domestic by building materials, and the performance calculation include the sorption flux, Fm and the equivalent ventilation rate, Fv, eq by SBM, which could provide to reference of the national standards.

Abstract: Digital holography microscopy has been widely used as a testing technology in many areas for the ability of real-time three-dimensional imaging. In this study we focus on understanding the system imaging mechanism and recording capacity of the off-axis image plane digital holography (IPDH) which has several advantages. Wigner distribution function and space-bandwidth product are utilized to examine the minimum requirement for the recording capacity of the CCD camera. The discussion provides a good understanding and a useful guide to the formation of practical IPDH systems.

Abstract: This paper presents a numerical method for kinematics analysis of Mcpherson suspension based on displacement matrix method. A mathematical model for kinematics analysis of Mcpherson suspension is established and the kinematical properties of Mcpherson suspension are analyzed using this method. The numerical method for solving this problem is discussed and the relevant program is developed. This method simplifies the solving process of kinematics properties analysis of Mcpherson suspension and is efficient especially for computer-based solving process.

Abstract: In this paper, AL-Mg-Mn-RE series alloys are becamed object of study.They are prouced with pure alumimum, pure Mg,electrolytic Mn and mix rich Ce rare earth. The effect of rare earth content on the resistance of the Al-Mg-Mn-RE series alloys are investigated by using Anodic polarization curves, electrochemical impendance spectroscopy. The results showed that their corrosivity is influenced by RE content in aluminum alloys.NO.3.3 impedance of Al-Mg-Mn-RE alloys is larger in the Nyquist diagram and its corrosion current of alloy decreases obviously. Then corrosivity of alloy is the best and the RE content is 0.3%,When the RE content is higher or lower than it that corrosivity isn’t improved but descended.

Abstract: Preparation of biodiesel from tung oil catalyzed by five Brǒnsted acidic ionic liquids (ILs) with propyl sulfonic acid group was investigated. These ILs show good catalytic activity for the transeserification of tung oil. Among these ILs, [C3SO3Hmim]HSO4 showed a highest catalytic activity. In addition, these ionic liquids had a good reusability and could be easily separated from the biodiesel.

Abstract: As a result of the changes that occurs the lubricant oil during their use, aged engine oils tend to differ in chemical and physical composition from virgin oil. We have chosen for study theses variations (changes) the oil that is the most sell in Algeria for cars with engine gasoline. For this investigation the oil was examined at different kilometres. A combination of oil acidity and deposit formation were used to follow the ageing. Our results were compared to standards, which helped us further refine our experiences to draw conclusions about the future for the waste oil collected.
