of wall in direction of west and east In Fig. 3, measured exterior surface temperature of wall in the direction of west and east for energy saving cubicle on August 10th in Chongqing is shown. This day... Measured exterior surface temperature of east and west wall for energy saving cubicle on August 10th, 2010 4.2 Analysis of window surface temperature Figure 4 shows the interior and exterior surface......
on the surface. Accurate analysis is needed because mechanical characteristics of material are changed by scanning laser energy[3-4]. Laser surface hardening has two advantages. First, there is no much deformation of material since input energy is not too much. Second, the surface of material is smooth after laser hardening so it does not need post-process. It is required to search the optimum process......

and the results showed that ion irradiation could effectively reduce the surface roughness. In this work, a non-contact surface finish process was investigated with high-energy ion irradiation to improve... on the surface of the micro punch. The sputtering rate not only depends on the atomic mass and chemical bond of the material, but also relates to the energy, density and incident angle of the ions......

Study on the Surface Free Energy of Ground CaO by JGC付正义摘 要:CaO formed by decomposing CaCO3 at 1450℃ was ground in a vibrational mill, then the long-time ground sample was reheated at different temperatures. Inverse Gas Chromatography (IGC) was used to measure the variation of the sample’s surface free energy under grinding and reheating......
