| 1 | 超低碳钢连铸过程中Ti和P对水口结瘤的影响显示文摘浇注含Ti超低碳钢时,浸入式水口内产生结瘤,严重影响生产效率,同时对产品质量造成危害。根据企业生产的经验,随着超低碳钢中Ti和P含量的增加,水口结瘤的问题越来越严重。通过深入分析实际生产过程的试样和实验室研究,阐明浇注超低碳钢时Ti和P对水口结瘤的影响。分析了含Ti含P的超低碳钢水口结瘤物的成分,结果表明结瘤物的主要成分是氧化铝(>90%),Ti含量较少(0.58%~3.58%)。采用脉冲分布解析原子发射光谱法(OES-PDA)测得氧化夹杂物的大小随Ti含量的增加而变小。采用液滴法测定了溶质Ti和P对钢液/Al2O3体系的润湿性影响,结果表明Ti和P使体系接触角和钢液表面张力降低,其中Ti能够降低体系的接触角只是在其具有反应湿润性的情况下。研究表明Ti和P对产生结瘤的作用有显著区别:只要形成的表层界面具有润湿性,Ti就可以降低Al2O3夹杂物的大小,而氧化铝夹杂物颗粒越小,越容易结瘤。为了不产生结瘤就必须控制好Al脱氧的时间和Ti的加入时间。P可以增加Fe-Ti-P三元体系的润湿性是因为P可以增加Ti的活度,降低钢液的粘度。与Ti相比,P对产生结瘤的影响较小。 | C Bernhard A Karasangabo M Egger A Pissenberger 贾洪海(译) | 2012 | 世界钢铁2012，12，5： | 17 |
| 2 | Comparison of high-resolution ultrasound and MR-enterography in patients with inflammatory bowel disease显示文摘AIM:To compare the results of high-resolution ultrasound(HR-US) and magnetic resonance enterography(MRE) examinations in patients with inflammatory bowel disease(IBD).METHODS:The reports of 250 consecutive cases with known IBD,who had an MRE and HR-US examination,were retrospectively analyzed.Using a patient-based approach we evaluated morphological disease features such as affected bowel wall,stenosis,abscess and fistula.The comparison between the two modalities was based on the hypothesis,that any pathological change described in any imaging modality was a true finding,as no further standard of reference was available for complete assessment.RESULTS:Two hundred and fifty examinations representing 207 different patients were evaluated.Both modalities assessed similar bowel wall changes in 65% of the examinations,with more US findings in 11% and more MRE findings in 15%.When the reports were analyzed with regard to 'bowel wall inflammation',US reported more findings in 2%,while MRE reported more findings in 53%.Stenoses were assessed to be identical in 8%,while US found more in 3% and MRE in 29%(P < 0.01).For abscess detection,US showed more findings in 2%(n = 4) while MRE detected more in 6%(n = 16).US detected more fistulas in 1%(n = 2),while MRE detected more in 13%(n = 32)(P < 0.001).The most common reason for no detected pathology by US was a difficult to assess anatomical region(lesser pelvis,n = 72).CONCLUSION:US can miss clinically relevant pathological changes in patients with IBD mostly due to difficulty in assessing certain anatomical regions. | Andreas G Schreyer Cynthia Menzel Chris Friedrich Florian Poschenrieder Lukas Egger Christian Dornia Gabriela Schill Lena M Dendl Doris Schacherer Christl Girlich Ernst-Michael Jung | 2011 | World Journal of Gastroenterology2011，17，8： | 7 |
