1THE EFFECT STRESS ON THE MAGNETOSTRICTION IN TWIN- FREE SINGLE CRYSTALS Tb_y Dy_(1-y) (Fe_(1-x) T_x)_2 (T=Al,Mn)显示文摘Magnetostriction at room temperature under various conditions of compressive prestress and applied fields in Tb yDy 1-y (Fe 1-x T x) 2 (T=Al,Mn) twin-free single crystals were investigated. The substitution of Al or Mn for Fe lowers the magnetostriction un-der ordinary temperature and pressure, but it also decreases the saturation field, which enables these materials with potential benefits for applications.Y.X.Li, G.Z.Xu,J.P.Qu, F.G.Liu and B.W.

5GROWTH KINETICS OF SINGLE INCLUSION PARTICLE IN MOLTEN MELTS显示文摘On the basis of the single-particle framework,a new theory on inclusion growth in metallurgical melts is developed to study the kinetics of inclusion growth on account of reaction and collision. The studies show that the early growth of inclusion depends on reaction growth and Brawnian motion collision,and where the former is decisive,the late growth depends on turbulence collision and Stokes' collision,and where the former is dominant;collision growth is very quick during the smelting process,lessened in the refining process,but nearly negligible in the continuous casting process.B.W.

8六种玻璃离子粘固剂断裂模式的比较显示文摘目的采用赫兹压痕实验,研究不同类型玻璃离子粘固剂的断裂模式。方法选取6种玻璃离子粘固剂材料(A^D为酸反应固化型,其中A、B无加强成分,C为银粉加强,D为陶瓷加强;E、F为树脂改良型)制作圆盘形试件各10个,直径为10mm,厚度为2mm。置于玻璃纤维加强尼龙6,6基底上,通过直径为20mm的加载头进行静态加载,记录初始断裂载荷,扫描电镜观察试件断裂模式。结果材料A、B、C、D均表现为相似的脆性断裂模式,材料E、F多数试件为局部不完全断裂。材料A^F的初始断裂载荷分别为(258.86±10.49)、(230.88±21.66)、(281.90±25.39)、(282.11±9.60)、(756.67±83.50)和(1148.00±147.78)N,前4种与后2种间差异有统计学意义(P<0.05)。结论玻璃离子粘固剂的固化类型决定其断裂模式;金属或陶瓷加强成分增加试件承受载荷能力的效果不大。王焱 张新春 Darvell B.W. 2006中华口腔医学杂志2006,41,11:3
9多支冠状动脉疾病且曾行冠状动脉搭桥术的患者中血运重建方法的预测因素和经皮冠状动脉介入术或再次冠状动脉搭桥术的长期预后显示文摘Aims: The optimal revascularization strategy in patients with symptomatic multivessel coronary artery disease(CAD) and previous coronary artery bypass grafting(CABG) remains unknown. Methods and results: We evaluated all patients with previous CABG undergoing isolated, non- emergency multivessel revascularization between 1 January 1995 and 31 December 2000. The analysis concentrated on the independent predictors of the revascularization method, as well as on long- term mortality and its predictors, after calculating a propensity score for the method of revascularization. There were 2191 patients(1487 with reoperation and 704 with percutaneous coronary intervention, PCI) in the study. The most important factors in choosing reoperation were presence of more diseased or occluded grafts, previous infarction, lower ejection fraction(EF), longer interval from first CABG, and more total occlusions of native arteries, as well as absence of a patent mammary graft. The distribution of the propensity score was skewed towards the two extremes. At 5 years, the unadjusted cumulative survival was 79.5% for CABG and 75.3% for PCI, P=0.008. After adjustment for the propensity score for PCI vs. CABG, PCI was associated with a hazard ratio of 1.47(0.94- 2.28), P=0.09. The most powerful predictors of mortality were higher age and lower EF. Conclusion: The choice of the revascularization method in patients with previous CABG is dictated mostly by anatomical considerations and less by clinical characteristics. In contrast, clinical characteristics predominantly affect long- term outcome, whereas the method of revascularization has a limited effect. A randomized clinical trial addressing this important segment of the population with ischaemic heart disease is warranted.Brener S.J. Lytle B.W. Casserly I.P. 王亭忠 2006世界核心医学期刊文摘(心脏病学分册)2006,2,6:3
