梅树村剖面,已被推荐为国际前寒武系—寒武系界线层型候选剖面。本文论述了对该剖面进行的古地磁研究,在剖面的碳酸盐及磷酸盐台地相地层中,依次采集了159块古地磁样品。热退磁结果表明:剖面中的大多数岩石已被现今地磁场强烈重磁化,但仍有57块样品保存有呈互为对踱的剩磁方向(平均D/l=4.2°/7.1°,K=9,α_(95)=6.6。),并计算出古地磁极位置为68.8°N,270.7°E。这与华南年轻的显生宙岩石所得到的极位置皆不一样。该项研究的结果构成一极性带,至少有9次倒转。此极性带与苏联西伯利亚,澳大利亚及美国西部所获得的资料对比,都共同显示出以频繁的极性倒转为特征。

本研究设计了一种低成本短流程粉末冶金固结与加工技术制备了亚稳β型Ti-5553合金,主要包括快速粉末热压、单道次锻压和简单退火热处理。研究揭示了合金在加工过程中的组织演变机理、力学性能优化机理和组织性能关系。结果表明:经过在1275℃流动氩气气氛环境的快速热压,所得固结态合金相对密度高、宏微观组织均匀,无明显缺陷。经过单道次锻压及快速退火处理后,合金的微观组织和力学性能得以调控和优化,其微观组织和力学性能都对热处理温度的变化有较高的敏感性。当热处理温度为700℃和750℃时,合金展现出良好的强塑性匹配,抗拉强度和伸长率分别为1335 MPa和6.6%、1215 MPa和7.2%,原因是多级析出相的组织结构可同时稳固合金的力学性能强化效果、提高合金的均匀协调变形能力,使合金具有高强度和可接受的塑性。

Open Journal of Radiology 2016年第3期6卷 233-242页

作者： Jimmy Tanche Wang Paul Babyn Gary Groot rob Otani Department of Radiology University of Saskatchewan Faculty of Medicine Royal University of Hospital Saskatoon Canada Department of Surgery University of Saskatchewan Faculty of Medicine Royal University of Hospital Saskatoon Canada

Purpose: The objective of the study was to design and implement an electronic synoptic report for thyroid sonography that incorporates the thyroid imaging reporting and data system (TIRADS) and assess potential for reducing unnecessary fine needle aspiration biopsies (FNAB) of thyroid nodules. Methods: The electronic synoptic report was developed using a relational database based on elements from TIRADS and a multidisciplinary consensus statement for thyroid reporting. A retrospective analysis of 138 patients with previously reported thyroid sonographic exams was evaluated for the presence of these elements. The electronic synoptic report calculates the TIRADS score and generates a formal report. Using the TIRADS score the potential decrease in unnecessary FNAB was estimated. Results: Key TIRADS elements were variously reported ranging from 43% for the thyroid nodule’s architecture as solid or cystic. Thyroid nodule echogenicity and calcification was commented in 27% and 23%, respectively. Other features of the TIRADS score were commented in 0% to 8% of the official reports. Estimated reduction for potentially reduced need for FNAB was 34.5%. Conclusions: This study is the first implementation of synoptic reporting using a relational database for sonography of thyroid nodules. Implementation of an electronic standardized synoptic reporting system may facilitate more accurate, and more comprehensive reporting for thyroid ultrasound scanning of thyroid nodules. The use of TIRADS was estimated to be able to potentially reduce the need for FNAB which was significant.
