针对现阶段国内隧道施工中采用的通信定位手段通信信号不佳,无法提供精准定位信号的现象,基于现场可编辑门阵列(FPGA)为主控硬件提出一种以超宽带(UWB)定位技术为原理的无线传输定位系统,UWB定位基本原理基于三边测量算法并在后端数据处理中引入自适应卡尔曼滤波进一步提高其定位精度。该系统硬件层面具有低功耗、高效率的优点;算法层面卡尔曼滤波可以使系统达到更高精度,静态测距精度可达到0.1 m以内,动态测距精度可达到0.2 m以内。该系统可对工作人员长时间进行高精度、高效率的定位。经实验验证,该系统能够在无网络的情况下及时进行高精度跟踪定位,具有极强的鲁棒性。

东天山地区发育大量的印支期岩浆岩,其岩石成因及其动力学背景对于理解中亚造山带晚期构造演化过程具有重要意义。本文对东天山尾亚和天湖地区新发现的闪长质岩墙开展了岩石学、地球化学及锆石U-Pb年代学和Hf同位素综合研究。锆石U-Pb测年结果表明,天湖地区闪长质岩墙形成时代为246.6±1.9Ma和248.4±3.8Ma,为早三叠世岩浆活动的产物;尾亚地区闪长质岩墙形成时代为237.7±1.3Ma、234.4±2.1Ma、238.3±1.6Ma和233.9±1.6Ma,为中三叠世岩浆活动的产物。岩石地球化学特征显示研究区闪长质岩墙总体呈现出较高硅(SiO_(2)为60.51%~67.56%)、富碱(K_(2)O+Na_(2)O为6.39%~8.23%)和准铝质(A/CNK为0.91~0.98)特征,属于高钾钙碱性系列。岩石相对富集K、Rb、Ba等大离子亲石元素(LILE),亏损Nb、Ti、Ta等高场强元素(HFSE),具有微弱Eu负异常(δEu=0.83~1.03)。锆石Hf同位素分析显示样品具有正的ε_(Hf)(t)值(+1.26~+6.32)和较年轻的亏损地幔模式年龄(tDM1=638~828Ma)。结合岩石地球化学特征,表明闪长质岩墙可能为交代地幔楔部分熔融形成的幔源岩浆底侵诱发新生下地壳熔融,随后由底侵的玄武质岩浆与壳源长英质岩浆混合形成。结合区域地质和相关构造环境分析,指示闪长质岩墙形成于板内伸展环境。结合前人研究,本文认为东天山发育的闪长质岩墙群可作为区域伸展作用的重要标志,表明东天山在印支期为陆内伸展的构造环境。

Journal of Materials Science & Technology 2016年第9期32卷 925-929页

In recent years, zinc based alloys as a new biodegradable metal material aroused intensive interests. However, the processing of Zn alloys micro-tubes （named slender-diameter and thin-walled tubes） is very difficult due to their HCP crystal structure and unfavorable mechanical properties. This study aimed to develop a novel technique to produce micro-tube of Zn alloy with good performance for biodegrad- able vascular stent application. In the present work, a processing method that combined drilling, cold rolling and optimized drawing was proposed to produce the novel Zn-5Mg-1Fe （wt%） alloy micro- tubes. The micro-tube with outer diameter of 2.5 mm and thickness of 130 μm was fabricated by this method and its dimension errors are within 10 μm. The micro-tube exhibits a fine and homogeneous microstructure, and the ultimate tensile strength and ductility are more than 220 MPa and 20% respectively. In addition, the micro-tube and stents of Zn alloy exhibit superior in vitro corrosion and expansion performance. It could be concluded that the novel Zn alloy micro-tube fabricated by above method might be a promising candidate material for biodegradable stent.

CO_(2)和环氧化合物环加成为环状碳酸酯是化学固定CO_(2)的有效途径之一。碱金属和碱土金属卤化物因低毒、成分简单、易处理、廉价易得且稳定而成为催化该反应的常用催化剂,但是其单独使用,催化活性低。为提高其催化活性,氢键供给体类、路易斯酸类、配体类和含HBD的配位类等助催化剂相继被开发。本文对该研究领域的进展情况进行了综述,探讨了助催化剂开发过程中面临的问题和挑战,以期促进碱金属和碱土金属卤化物在该反应工业化过程中的开发和应用。
