With the help of the structures, crash kinetic-energy can be completely absorbed or dissipated for the aim of safety. Two composite structures(circumscribed circle structure and inscribed circle structure) were constructed. In addition, comparison and optimization of the crashworthy characteristic of the two structures were carried out based on the method of explicit finite element analysis(FEA) and Kriging surrogate model. According to the result of Kriging surrogate model, conclusions can be safely drawn that the specific energy absorption(SEA) and ratio of specific energy absorption to initial peak force(REAF) of circumscribed circle structure are lager than those of inscribed circle structure under the same design parameters. In other words, circumscribed circle structure has better performances with higher energy-absorbing ability and lower initial peak force. Besides, error analysis was adopted and the result of which indicates that the Kriging surrogate model has high nonlinear fitting precision. What is more, the SEA and REAF optimum values of the two structures have been obtained through analysis, and the crushing results have been illustrated when the two structures reach optimum SEA and REAF.展开更多

Materials and Methods: This single-center, retrospective study included 25 patients who underwent EVAR for abdominal aortic aneurysm at our institution. A 1-mm horizontal cross-sectional slice of NCT and CECT from each patient was retrospectively reviewed. The area from the abdominal aorta to the common iliac artery was divided into four zones. A centerline was created using the NCT by manually plotting the center points. Subsequently, the centerlines were automatically extracted and manually corrected during the arterial phase of CECT. The diameter and length of each zone were measured for each modality. The mean diameters and lengths of the target vessels were compared between NCT and CECT. Results: The measurements obtained using both methods were reproducible and demonstrated good agreement. The mean differences in vessel length and diameter measurements for each segment between NCT and CECT were not statistically significant, indicating good consistency. Conclusion: NCT may be useful for preoperative EVAR evaluation in patients with renal dysfunction or allergies to contrast agents.展开更多

Unmarked item, compared with marked item,is more natural, more neutral, more fundamental, and has higher using frequency and wider distribution. From the perspective of markedness theory, the study, collecting 86 English passives and 85 Chinese passives(including 35 notional passives and 50 Beisentences), contrastively analyzes the unmarkedness of English and Chinese passives from the aspects of patient animacy, emotional color, and tense through example-illustration and description. The analysis shows that the unmarkedness of English and Chinese passives has different expressions in the three aspects. Inanimate patient has stronger unmarkedness in both English and Chinese passives, for it is more frequently-used than animate patient. According to people's cognition and language using habits, the emotional color of English passives and Chinese notional passives is neutral in most cases, so the neutral emotional color is unmarked.But in Chinese Bei-sentences, negative emotional color has stronger unmarkedness. As for the tense expression, English passives have wider distributions in time span and simpler structure than Chinese passives. Thus, English passives possess stronger unmarkedness in the light of tense. According to the analysis, the study proposes feasible advice for second language acquisition and translation.展开更多

[Method] By u- sing pressure and temperature observed by automatic station and artificial station in Qingxian from January of 2009 to December of 2010, compara- tive analysis of observation data was conducted, and formation reason of difference value was discussed. E Resultl Monthly average pressure differ- ence between automatic station and artificial observation value was from -0.7 to 0.1 hPa. Difference value of monthly average maximum pressure was from -0.5 to 0.4 hPa, while difference value of monthly average minimum pressure was from -0.7 to 0.2 hPa. Difference value of monthly extremely maximum pressure was from -0.3 to 0.6 hPa, while difference value of monthly extremely minimum pressure was from -1.1 to 0.1 hPa. Monthly average temperature difference value was from -2.0 to 0 ℃. Difference value of monthly average maximum temperature was from -0.4 to 0 ℃, while difference value of monthly average minimum temperature was from -0.1 to 0.2 ℃. Difference value of monthly extremely maximum temperature was from -0.3 to 0.3 ℃, while difference value of monthly extremely minimum temperature was from -0.3 to 0.3 ℃. [ Conclusion] Generation reason of observation difference mainly included differences of observation instrument and principle, differences of data collection time and method, different sensor installation positions and environments, manual intervention and observation error.展开更多

It comes to the conclusion that the translator has to follow the fundamental translation principle of functional equivalence, that is, to faithfully reproduce the linguistic and stylistic features of the original, while retaining the verbal beauty of the original as much as possible. Through contrastive analysis, this paper also argues that stylistic features should be consistent with the choice of word, syntactic structures, rhetorical devices, and overall textual layout.展开更多
