well represent the most common one in the residential zone [27]. The combination of two parameters termed distance ratio and width ratio can be used to measure the extent of obstruction......
. Experimental study on the effect of wind angles on pressure distribution of train streamlined zone and train aerodynamic forces [J]. Journal of Wind Engineering and Industrial Aerodynamics, 2018, 174......
of the reaction is possible only by diffusion of the reagents through the product layer. Accordingly, the second exothermic peak on the DSC curve at a higher temperature indicates the completion of the reaction..., the composite granules with uniform distribution of TiO2 particles were formed. Subsequent heating of mechanically alloyed materials causes the activation of an exothermic reaction of TiO2 reduction......
recrystallization on microstructure and mechanical properties of welding zone in Al-Mg-Si aluminum profile during porthole die extrusion [J]. Transactions of Nonferrous Metals Society of China, 2019, 29(9): 1803-1815......
, is smoothly absorbed by the aluminum melt. Aluminum oxide, obtained during the redox reaction, dissolves in cryolite, after which aluminum and silicon are fused together and transferred to the melt... of silicon; however, the process occurs directly in the contact zone of the melt with the surface of the tablet as well as in the tablet volume (upon the interaction of aluminum powder particles......
]. Only a few studies have applied hydrogeochemical knowledge to corrosion processes underground and including diffusion [30, 31]. However, they were dealing with corrosion problems under different... by inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS) techniques. 2.2 Batch-reaction modelling methods and setup The PHREEQC program......
and there needs a buffering zone for the advancement of the control strategy. Hence, we assume that the radius is time-varying with an exponential convergence form. That is where r1 and r2 are positive......
experiment site. The project is located in the Hulunbuir Plateau, the northern part of Ergun, which is a warm cool humid, semi-humid forestry and animal husbandry climate zone in the northwestern... the pavement, effectively reducing the freezing period time and the temperature gradient. Finally, the diffusion of water vapor inside the subgrade is also an important factor in the enrichment of water near......
, a coating layer of cubic boron nitride was applied on the inner surface of the graphite sheet as a thermal barrier layer, which inhibited the diffusion of carbon during sintering. The SPS sintering... phase exists in Zr-25Ta-5Ti alloy, indicating that the diffusion is sufficient during the sintering process. Figure 3 SEM images showing the microstructure of Zr-Ta-Ti alloys: 3.3 Mechanical properties......
engineering, was employed. The local sand was selected with its gradation illustrated in Figure 2. The gradation curve of sand was located between the upper and lower values of zone 2 in the gradation area......
