| 1 | Effect of Temperature and Phase Constitution on Kinetics of La Diffusion显示文摘The diffusion of La in ε-Fe 2~3N(ε)and γ′-Fe 4N (γ′)phases produced by plasma nitriding was studied. It is found that with increasing nitriding time, the ε phase continuously decomposes into γ′ one under employed experimental conditions and compared with γ′ phase or ε+γ′ ones, the mono one ε has an impedient effect on depth of La diffusion. The growth of La layer in dual phases and mono one follows an approximate exponential law and a parabolic one, respectively, and this kinetics law does not change with increasing temperature. The effect of increasing temperature in the range of 520 to 560 ℃ on La diffusion depth is less than that of phase constitution change such as the decomposition of ε phase into γ′ one. | 阎牧夫 Sun Y Bell T 刘志儒 夏立芳 | 2002 | Journal of Rare Earths2002，20，4： | 7 |
| 2 | 温度和相结构对镧扩散动力学的影响显示文摘研究了等离子体渗氮过程中La在密排六方ε Fe2~ 3N(ε)和面心立方γ′ Fe4N (γ′)双相中的扩散动力学规律。与γ′相或ε +γ′双相比较 ,发现ε相对La的扩散具有阻碍作用。一定温度下 ,随着渗氮时间的延长 ,ε相不断分解出γ′相 ;La在单相 (如γ′相 )和双相ε +γ′中的扩散深度分别呈抛物线和近似指数规律增加。提高渗氮温度 ,La扩散的深度增加 ,但其扩散动力学规律并未因此而改变 ;温度从 5 2 0℃升高至5 | 阎牧夫 Bell T Sun Y 刘志儒 夏立芳 | 2001 | 中国稀土学报2001，19，2： | 2 |
| 3 | Acute-on-chronic liver failure: Controversies and consensus显示文摘Acute-on-chronic liver failure(ACLF)is a poorly defined syndrome characterised by rapid clinical deterioration in patients with chronic liver disease.Consequences include high short-term morbidity,mortality,and healthcare resource utilisation.ACLF encompasses a dysregulated,systemic inflammatory response,which can precipitate extra hepatic organ failures.Common precipitants include infection,alcoholic hepatitis,and reactivation of viral hepatitis although frequently no cause is identified.Heterogenous definitions,diagnostic criteria,and treatment guidelines,have been proposed by international hepatology societies.This can result in delayed or missed diagnoses of ACLF,significant variability in clinical management,and under-estimation of disease burden.Liver transplantation may be considered but the mainstay of treatment is organ support,often in the intensive care unit.This review will provide clarity around where are the controversies and consensus in ACLF including:Epidemiology and resource utilisation,key clinical and diagnostic features,strategies for management,and research gaps. | Natalie L Y Ngu Eliza Flanagan Sally Bell Suong T Le | 2023 | World Journal of Gastroenterology2023，29，2： | 2 |
