Experimental Study on the Mechanical Properties of Novel Plate-knitted Composite Tracheal Stents

A new knitted composite artificial tracheal stent made of polyglactin(PGLA) and polypropylene (PP) filaments for reinforcement and regeneration of human trachea has been developed by plated-knitting technique on a small-diameter circular knitting machine. Both tensile and compressive tests were carried out to determine the Young's modulus and the critical pressure corresponding to crushing of the stent. The experimental results confirmed that the new type of knitted composite artificial stent is mechanically feasible.     

Effect of Nano-SiC and Nano-Si Doping on Critical Current Density of MgB_2

The discovery of superconductivity in magnesium diboride (MgB2) has opened up a new field in materials science research. It offers a possibility of a new class of high performance superconducting materials for practical applications because of the relatively low cost of fabrication, high critical current densities (Jc) and fields, large coherence length, absence of weak links, higher Tc(TC = 39K) compared with Nb3Sn and Nb-Ti alloys (two or four times that of Nb,,Sn and Nb-Ti alloys). However, the weak flux pinning in the magnetic field remains a major challenge. This paper reports the most interesting results on nanomaterial (SiC and Si) doping in magnesium diboride. The high density of nano-scale defects introduced by doping is responsible for the enhanced pinning. The fabrication method, critical current density, microstructures, flux pinning and cost for magnesium diboride bulks, wires and tapes are also discussed. It is believed that high performance SiC doped MgB2 will have a great potential for m     

沿海农业区施用农药的环境费用分析及管理对策

从环境经济学这一新的视角探讨了沿海农业区的农药污染问题.选择濒临同安湾的厦门同安区为案例研究区,以1999年7月至2000年6月为研究年限,对该地区施用农药的环境费用加以货币化评估.本研究将环境经济学的评估技术与EQC和SoilFug模型以及层次分析法结合使用,使环境费用的货币化估算更具科学性.结果表明,施用农药产生的外部费用与私人成本的比值大于0.8.基于环境费用分析和SoilFug模型的运算结果,运用线性规划模型求出研究区主要农作物的最佳种植面积,即在减少、控制农药用量的前提下又使经济效益最大的种植结构,以期寻求经济与环境协调发展的新途径.此外,还就征收农药产品税以及发挥价格杠杆作用控制农药污染问题作了探讨.     

二十世纪五六十年代中国人口政策研究

二十世纪五六十年代，党和政府初步认识到了人口问题的紧迫性，制定了以节制生育、提高人口素质为核心的人口政策，并在一段时期内和一定程度上得到落实。但由于种种原因，此期的人口政策未能有效地贯彻下去，因而人口数量的控制没有非常明显的成效，人口的素质也未有非常明显的提高。     

Study on the Medical Image Distributed Dynamic Processing Method

To meet the challenge of implementing rapidly advanced, time-consuming medical image processing algorithms, it is necessary to develop a medical image processing technology to process a 2D or 3D medical image dynamically on the web. But in a premier system, only static image processing can be provided with the limitation of web technology. The development of Java and CORBA (common object request broker architecture) overcomes the shortcoming of the web static application and makes the dynamic processing of medical images on the web available. To develop an open solution of distributed computing, we integrate the Java, and web with the CORBA and present a web-based medical image dynamic processing methed, which adopts Java technology as the language to program application and components of the web and utilies the CORBA architecture to cope with heterogeneous property of a complex distributed system. The method also provides a platform-independent, transparent processing architecture to implement the adva
