are mainly concentrated at the hole wall and the corners of the rectangular block, and their number will decrease with the increase of the injection speed (especially the inner hole wall). The number of weld......
mass ratio (0.6-1.0), leaching temperature (40-80 °C) and leaching time (15-75 min). Blank experiments using only H2SiF6 as lixiviant were also conducted. A tubular reactor (PTFE TR, inner......
the formation of Cu6Sn5 at room temperature. The presence of Cu6Sn5 as the only reaction product in as-deposited and aged Cu/Sn couples can be rationalized in terms of the structure of Cu6Sn5. Cu6Sn5 has... is detected as the reaction product (Fig.4(a) and 4(b)), which is the same as the results for the couples aged at room temperature. BSE image for a couple annealed at 373 K is shown in Fig.5, confirming......
to be accurate based on the assumptions that: 1) the product phase is randomly distributed; 2) nuclei are randomly distributed; 3) the average growth rate is independent of position in the sample; 4) impingement on objects other than neighbouring domains of the product phase is negligible and 5) blocking resulting from anisotropic growth is negligible. The logarithmic form of Eq. (10) yields  ......
of biomedical Mg alloy in physiological environment. They conclude that OH- can raise localized corrosion and stabilize the corrosion product Mg(OH)2, but Mg(OH)2 layer is loose and cannot provide... of corrosion product after immersion. Some researchers [36,40,64] just remove the samples from the solution, rinse them with distilled water, and weigh the samples. Others [49] try to move the surface corrosion......
the product of magma activity in different phases and different stages. In the Danchi mineralization belt, the rock body is characterized by small size and buried in the deep, whose wall rock alters... are characterized by the equal interval, which belong to the tectonic product in the same stress field. So, the equidistant fracture site is usually regarded as one of the important prospecting......
of this residue to act as a liming agent, since about 11.2 t of this residue is required to replace 1 t of a commercial ground limestone product produced by SMA Mineral Ltd. (Finland), which has an NV of 38... of this residue is required to replace 1 t of a commercial ground limestone product produced by SMA Mineral Ltd. (Finland). The better acid neutralizing value of the fly ash is reasonable, since the total Ca......
the distance relationship between sample by the archaeal and bacterial communities. Statistical product and service solution (SPSS) were conducted to reveal the correlation between geochemical variable... low. The statistical product and service solutions (SPSS) based on the percentage of Leptospirillum and geochemical variables revealed that the concentrations of Cu2+ and Fe3+ were influence factors......
carboxylates. The IR spectra of the reduced samples are shown in Fig. 2(b). The spectrum of M1-300R sample indicates that the final product obtained at this stage does not contain impurities. Two bands...) corresponds to the IR spectra of reduction products. The spectrum corresponding to M1-400R indicates that the final product does not contain impurities. The results obtained for M2-400R and M3-400R......
into the quasi-cup samples as the desirable final product. All the sheets are circular blanks with diameters of 50 mm. The sheets are prepared from two different materials: galvanized iron and aluminum alloy... the quasi-static condition and the blank is shaped into the desirable quasi-cup form. Figure 1(b) illustrates the desirable final product and rigid die and punch. The aluminum sheets are prepared with three......
