We present new measurements on the thermal properties of granitic rocks collected from a nearly 1000-m deep well in Central Portugal, using a transient plane source technique with a hot disk sensor. At room-temperature, the granite has, on average, a thermal conductivity of 3.1?W?m?1 K?1...
The effect of temperature on thermal conductivity, thermal expansion, specific heat, and mass loss of HSC is discussed. Test data indicate that the type of aggregate has a significant influence on the thermal properties of HSC, while the presence of steel fiber reinforcement has very little ...
Yhat=0.6368+0.0821Te-0.0695 Hu+(0.0007Hu2).When temperature was stable,relative was 46.9%,formaldehyde emission was minimum.Conclusion Formaldehyde emission increases as temperature increases.It slightly decreases first,then increases as relative humidity increases.Prevention of fitment pollution in summer ...
The specific heat and enthalpy of four different types of meats (Veal, Hashi, Noeimi, and Najdi) were determined in the temperature range of 40 to 40°C and moisture content range of 3075% (wet basis). The two properties were measured by the modulated differential scanning calorimeter (MDSC...

Regardless of thermal annealing treatment, all the NPs thin films show the negative Seebeck coefficients, indicating the n-type characteristics. As the annealing temperature increases, the electric conductivity increases while the Seebeck coefficient decreases. The electric conductivity of the thin film ...
1.A closed-form physical model of bse transit time considering thetemperature effect of the electronis obtained.推导了考虑电子温度效应之后的基区渡越时间的闭式物理模型,并与简单的漂移扩散模型作了比较,对于超薄基区,该闭式模型比漂移扩散模型准确。
The thermal, electrical, elastic and mechanical properties of heat resistant alloy of Ti-6.0%W-4.1%Al-3.5%Zr are investigated. It is shown that the resistivity variation rate approaches to zero during temperature elevation from 500 to 825°C. Changing in character of temperature dependence of the...
The effect of temperature and concentration on corrosion behavior and corrosion mechanism of epoxy and polyester resins in NaOH solution were studied, and ... H Hojo,T Tsuda,K Ogasawara,... 被引量: 11发表: 1986年 Study of the flame retardancy and thermal properties of unsaturated polyester res...
Influence of Sintering Temperature on the Mechanical Properties of Alumina Springs Low-pressure injection molding (LPIM) was used to produce helical alumina springs. Three sets of springs were sintered at 1550°C, 1600°C and 1650°C to o... RA Barbieri,CA Perottoni,JE Zorzi - 《Internation...
