| 1 | 等通道角挤压制备细晶ZK60镁合金的组织与力学性能显示文摘利用两种等通道角挤压(ECAP)方法(普通单步ECAP和两步ECAP)制备细晶ZK60合金。采用金相显微镜、扫描电镜、透射电镜和X射线衍射仪对合金的组织和织构进行观察,通过拉伸试验研究不同ECAP方法对合金力学性能的影响。结果表明:与单步ECAP变形相比,两步ECAP变形,由于降低了变形温度,晶粒细化效果更好;经过(240℃,4道次)+(180℃,4道次)两步ECAP变形后,合金晶粒细化至约0.8μm;合金的力学性能与材料的织构密切相关,由于存在织构软化效应,与挤压态相比,经单步ECAP变形后合金的强度有所降低,而伸长率明显提高;但经两步ECAP变形后,由于细晶强化和亚结构强化的作用,合金的强度得到提高。 | 何运斌 潘清林 覃银江 刘晓艳 李文斌 Yu-lung CHIU John J J CHEN | 2010 | 中国有色金属学报2010，20，12： | 17 |
| 2 | Correlation and prognostic significance of beta-galactoside alpha-2,6-sialyltransferase and serum monosialylated alpha-fetoprotein in hepatocellular carcinoma显示文摘AIM: To investigate the correlation between tissue ST6Gal I and serum msAFP in HCC patients, and to investigate their prognostic significance.METHODS: Preoperative sera,paired tumorous and non-tumorous tissues were collected from 19 consecutive patients who had undergone surgical resection of HCC.ST6Gal T activities in the tissues were measured by an in vitro microsomal enzyme activity assay. The percentages of tumor-specific msAFP in the sera were also estimated by an isoelectric focusing-immunoblotting assay.RESULTS: The tumor ST6Gal I activity was negatively correlated with serum msAFP percentage (r = -0.53,P = 0.019). Both decreased tumor ST6Gal I activity andincreased serum msAFP percentage were associatedwith poor tumor cell differentiation. Univariate analyses showed that both decreased tumor ST6Gal T activity (P = 0.028), increased serum msAFP percentage (P = 0.034) and poor tumor cell differentiation (P = 0.031)were associated with shorter overall survival. Multivariate analysis using the Cox regression model showed that the preoperative serum msAFP percentage (P = 0.022)and tumor cell differentiation status (P = 0.048) were independent prognostic indicators for patient overall survival.CONCLUSION: Our results indicate that the presence of msAFP in blood circulation is associated with a decreased activity of ST6Gal I activity in HCC. Both tissue ST6Gal I and serum msAFP are potential prognostic markers for patients with operable HCC. | Terence CW Poon Clarissa HS Chiu Paul BS Lai Tony SK Mok Benny Zee Anthony TC Chan Joseph JY Sung Philip J Johnson | 2005 | World Journal of Gastroenterology2005，11，42： | 4 |
| 3 | 高温合金差示扫描量热分析(DSC)的影响因素:粉末粒度和显微组织显示文摘对固溶强化型625镍基高温合金粉末进行升、降温差示扫描量热分析(DSC)试验,研究了不同粉末粒度(<37,45~53,75~105,105~150,150~355μm)对相变温度的影响。采用场发射扫描电镜(FESEM)、电子探针(EPMA)和同步辐射X射线衍射(SXRD)对625合金粉末的形貌、元素分布和相组成进行表征。结果表明:不同粒径PM625粉末均为树枝晶结构,枝晶间距在2~10μm范围,元素Ni和Cr倾向分布于枝晶干,Mo和Nb偏析于枝晶间。不同粒度的PM625粉末中均仅存在基体γ相。PM625粉末DSC加热曲线固相线附近区域拐点尖锐,表现为合金开始熔化温度(偏离基线的拐点)与名义固相线温度(切线交点)差异很小,不同粒度间的差异仅为2~5℃。合金完全熔化后重新冷却的过程中原始粉末的低偏析特性消失,冷却曲线固相线区域圆弧较大,名义固相线和终凝温度差较大,为53~65℃。DSC试验升温过程中不同粒径粉末的固、液相线以及初熔温度最大差异分别为3, 2和2℃,降温过程不同粒径粉末固、液相线温度差分别为6和2℃。0~355μm粉末粒径范围内,粒径对固溶强化型PM625高温合金粉末相变温度无明显影响。 | 郑亮 刘玉峰 Gorley Michael J Hong Zuliang DaySarah Tang Chiu C 李周 张国庆 | 2019 | 稀有金属材料与工程2019，48，5： | 3 |
