作为重要的透明微晶玻璃体系，含镁锌的铝硅酸盐玻璃展现了优异的力学、光学特性。大量研究关注该体系的核化和晶体生长过程，但锌镁替换对铝硅酸盐玻璃玻璃转变和晶化行为影响的物理机理尚不明晰。本研究以xZnO·(11-x)MgO·22Al2O3·67SiO2(x%=0%,2.2%,5.5%,8.8%,11.0%,摩尔分数)玻璃为研究对象，探究锌镁替换对铝硅酸盐玻璃的玻璃转变和晶化行为的调控规律。结果表明：随着锌逐步替换镁，玻璃转变温度慢慢下降，这是由于Zn2+较弱的场强和多一个电子层的屏蔽作用，玻璃网络骨架整体键合强度降低；析出晶相从单一的莫来石相转变为莫来石与锌铝尖晶石的混合相，这是由于Zn2+具有促进铝硅酸玻璃分相的作用；析晶温度降低，这主要是由于析晶温度附近黏温曲线变得更陡峭和析晶活化能降低。

采用溶剂热法制备了双金属(Co,Zn)ZIF-62晶体。XRD、XPS、SEM及DSC等结构、形貌和热学特性表征显示:获得的双金属(Co,Zn)ZIF-62晶体依然保持ZIF-62晶体结构,同时含有少量含Co的中间相;(Co,Zn)ZIF-62晶体形貌从棱角明晰的多面体向棱角模糊多面体转变,未知含Co杂相呈类球体;产物的熔点T_(m)逐渐降低;熔融淬冷制备的(Co,Zn)ZIF-62玻璃的玻璃转变温度T_(g)逐渐降低。上述现象可能均源于与有机配体中N原子形成配位键的Co和Zn离子的有限替换,以及晶体生长过程中Co—N键和Zn—N键的相互干扰。

Chinese Science Bulletin 2009年第2期54卷 311-317页

作者： SHAO Lei qiao PeiJun Pang Xiong WEI GangJian LI QianYu MIAO WeiLiang LI ang State Key Laboratory of Marine Geology Tongji University Shanghai 200092 China CNOOC Ltd. Shenzhen Guangzhou 510240 China Guangzhou Institute of Geochemistry Chinese Academy of Sciences Guangzhou 510640 China

The chondrite-normalized REE distribution patterns in recent sediments from the northern South China Sea and surrounding areas are similar, with the HREE values being almost equal to or slightly higher, and the LaN/LuN ratio being lower, than PAAS standards. However, samples from the Xijiang River, a major branch of the Pearl River system, show opposite trends, i.e., with slightly lower HREE values and higher LaN/LuN ratio than PAAS. The distribution of Nd isotopes in sediments from the northern South China Sea was controlled by the Pearl River and the inshore area of South China, respectively. The volume of εNd(0) from inshore areas of southern China is apparently higher than that from the Pearl River, and εNd(0) values in offshore sediments and Taiwan Island are between these values. The results clearly show that εNd(0) volume in the northeastern South China Sea is higher than in the southwest part of the northern South China Sea, indicating different source rock types. The main source rock of the Pearl River sediment is carbonate types and affects sediment deposition in the southwest of the northern South China Sea, while the source rock in the inshore area of southern China, mainly Mesozoic and Cenozoic granites, contributes to sediments in the northeastern area of the northern South China Sea. Due to different source rock types, the HREE values and the volume of εNd(0) in recent sediments supplied by the inshore area of southern China are higher than those from the Pearl River. Over 80% of the rapidly accumulated sediments on the northern slope of the South China Sea in the southeast of Dongsha Islands area were derived from Taiwan Island and from inshore areas of South China, with only less than 20% from the Pearl River.

Background The management of Barcelona Clinic Liver Cancer （BCLC） stage B hepatocellular carcinoma （HCC） is controversial due to the early recurrence after curative hepatectomy, and many variables were related to the prognosis. The purpose of this study was to predict the tumor recurrence in early postoperative period of the patients with BCLC stage B HCC. Methods From January 2004 to January 2012, 104 patients with BCLC stage B HCC underwent hepatectomy. Clinicopathological factors and follow-up data were statistically analyzed to establish a predicting scoring system. Results The overall survival rates for one, three, and five years were 69.2%, 52.7%, and 42.3%, and the disease-free survival rates for one, three, and five years were 52.9%, 47.3%, and 37.5%, respectively. The multiple factors analysis showed that the micro-vessel invasion, lymph nodes metastasis, multiple lesions, and the high expression of HMGB1 were independent factors （P 〈0.05）. A scoring system was established to predict the early recurrence within one year after the surgery for BCLC stage B HCC, according to the analysis results with a specificity of 85.1% and a sensitivity of 80.3%. Conclusion Variant clinicopathological factors were associated with early postoperative recurrence for BCLC stage B HCC and recurrence early after hepatectomy was more likely in patients with a higher score of the scoring system.
