Short copper standing wave （SW） structures operating at an X-band frequency have been recently designed and manufactured at the Laboratori Nazionali di Frascati of the Istituto Nazionale di Fisica Nucleare （INFN） using the vacuum brazing technique. High power tests of the structures have been performed at the SLAC National Accelerator Laboratory. In this manuscript we report the results of these tests and the activity in progress to enhance the high gradient performance of the next generation of structures, particularly the technological characterization of high performance coatings obtained via molybdenum sputtering.

managing microtia patients is always a challenge. multidisciplinary approach, good family support, well established doctorepatient rela-tionship and well organised patient-support groups are the essential elements for success. With the advancement of implantable hearing devices, more options will be available for the microtia patients. Otologists play a leading role in the whole management process. They not only provide proper guidance to the patients in choosing the correct path of the treatment, but also play a key role in organising and maintaining a cost-effective multidisciplinary rehabilitation team for the microtia patients.

农业是人类与环境联系最为紧密、互动最为频繁的领域之一,也是人类社会最为基础的经济部门.研究特定区域的居民如何选择其作物组合,对于探索早期社会经济基础和人类、环境与生物三者之间的互动关系都至关重要.本文选取位于我国自然地理南北过渡带的河南漯河郝家台遗址,从出土植物大遗存分析入手,揭示了当地在龙山文化至新砦期一直保持着以粟为主,黍为次,兼有少量稻和大豆利用的作物结构,并指出这与当地古环境的研究结果之间存在一定程度的反差.结合对当地农业传统和龙山时期开始的社会发展态势与区域间互动的分析,提出当地仰韶时期以来的农业传统、饮食偏好等文化因素在农业结构的形成过程中起到了重要的作用,促成了旱作农业传统在当地的长期延续.

通常的层析成象(或射线层析)是指利用在介质中射线传播的观测数据来重建介质参数分布的技术.当照射角和视角受到限制时或介质非均匀体的尺寸可以和波长相比拟时,射线层析的效果变得很差.衍射层析技术被引入以改善成象过程(mueller,et al.,1979;mueller,1980;Devaney,1984).在衍射层析中前向散射场(或衍射场)被用来重建物函数.在本文中我们不但利用前向散射,而且也利用后向散射场来进行重建.在公式推导中我们考虑了在野外测量中常用的几种几何布置,如地表反射剖面和多偏置井中垂直剖面(VSP),并且将观测过程公式化为点源(或线源)沿着测线移动的数据采集过程.我们也利用合成数据将衍射层析成象的结果与多源全息成象(吴如山、徐韶辉,1979)的结果进行了对比.

STUDy OF THE mICROSTRUCTURE AND PROPERTIES OF SImULATED HEAT AFFECTED zONE IN LASER WELDING OF ULCB 600 STEEL

引用

Acta metallurgica Sinica(English Letters) 2000年第1期13卷 151-156页

作者： Q. F. Wang J. H. Liu z. y. Li P. H. Li G. F. zhou and X. Chen( 1) Huazhong University of Sci. & Tech., Wuhan 430074, China 2) Technology Center of WISCO, Wuhan 430080, China)

The microstructure and properties of stmulated heat affected zone (HAz) of laser welded ULCB600 steel were investigate by applying the simulation technique with gleeble - 2000 dynamic thermal - me - chanical *** influence of the preheat condition on the microstructure and properties of simu- lated HAz of laser welded plate was also studied in order to evaluate the feasibility of reducing arisk that the ductility and toedness of HAz may be poor by using preheat *** results indicate that the grain size of laser - welded HAz simulated is very small no matter if there is preheat, the toughness of simulated HAz is therefore improved comparing to the base metal,and there is no obvious brittle - ductile transition in the range from - 80℃ to 20℃. The TEm analyses of sub -microstruc- ture also discover that microstructure constituent of both simulated HAz is dominative lath martensite. However, the shaf of martensite is relatively coarse,and the dislocation density is relatively high for simulated HAz with 200℃ preheat because of slower cooling rate. Combination of these tow factors is responsible for farer bardness and better toughness of simulated HAz with preheat condition.
