A gas mixture of CO_2 and Ar was injected into a Na OH solution bath. The flow field, volumetric mass transfer coefficient per unit volume(Ak/V; where A is the contact area between phases, V is the volume, and k is the mass transfer coefficient), and gas utilization ratio(η) were then measured at different gas flow rates and blow angles. The results showed that the flow field could be divided into five regions, i.e., injection, strong loop, weak loop, splashing, and dead zone. Whereas the Ak/V of the bath increased and then decreased with increasing gas flow rate, and η steadily increased. When the converter was rotated clockwise, both Ak/V and η increased. However, the flow condition deteriorated when the gas flow rate and blow angle were drastically increased. Therefore, these parameters must be controlled to optimal conditions. In the proposed model, the optimal gas flow rate and blow angle were 7.5 m^3·h^(-1) and 10°, respectively.展开更多

The mean phase and velocity distribution, circular area, and mean wall shear stress were calculated to determine the optimal operation parameter of the converter. The results showed that the slag phase gathered substantially in the dead zone. The circular flow was promoted by increasing the gas flow rate, Q, and decreasing the nozzle height, h. However, these operations significantly aggravate the wall shear stress. Reducing the nozzle diameter, d, increases the injection velocity, which may accelerate the flow field. However, when the nozzle diameter has an interval design, the bubble behaviors cannot be combined, thus, weakening the injection efficiency. Considering the balance between the circular flow and wall shear stress in this model, the optimal operation parameters were Q = 30000–35000 m^3/h, h = 425–525 mm, and d = 40 & 50 mm.展开更多

More specifi cally, and according to Peirce's categorial scheme, we suggest speech genres can be considered as ‘thirds', or purposeful and general ‘laws' overdetermining speech and its regularities. As such, the study of their semiotic mechanisms would fall within the sphere of Peirce's ‘speculative rhetoric', one of the three branches of his semeiotics. Overall, following Lyne, we suggest that any speech genre relates to three kinds of rhetorical ‘habits' —habits of representation, habits of objectifi cation, and habits of interpretation—which explain a sense of ‘reasonableness' permeating any discursive practice in society. We suggest that the task of discursive rhetorics should be to delineate, for given cultural communities, the productive and interpretive norms and mechanisms which govern the determination of discourse and elicit an intended interpretation on the interpreter's side.展开更多

Gorlée published her dissertation "Semiotics and the Problem of Translation: With Special Reference to the Semiotics of Charles Sanders Peirce", Douglas Robinson has been critically thinking about the essential problems concerning semiotranslation. In 2016, he published Semiotranslating Peirce to conduct a critical analysis of Gorlée's theories concerning semiotranslation with the Finnish translations of T. S. Eliot's poem and Wittgenstein's philosophy, and responded to 32 problems concerning what semiotranslation is, who or what the worldly agent of semiotranslation is, where semiotranslation occurs, whether semiotranslation is really irreversible, etc. As for their divergences, this review conducts a critical analysis, and further criticizes them on the scope of translation semiotics, the range of sign reference, the types of semiotic translation, and the role of translator in the translational sign transformation.展开更多
