Conventional imaging technique which unsubtracted bone was used first,use 3D treatment on workstation to reconstruct cerebral vessels,to diagnose aneurysm,vascular malformation and tumor as well as to evaluate the preoperative and postoperative efficacy.Subtract bone techniques including one by one slice subtraction,semi-automatic digital subtraction radiography,matched mask bone elimination and control tube exposure light spot imaging technique can show the vessels more clear without the interference of bone as well as the relationship between vessel and pathological changes more accuracy.

首先是未去骨的常规成像技术，利用工作站进行多平面重建技术、最大密度投影、容积再现、表面遮盖法等多种三维处理得到头部血管及肿瘤图像，对动脉瘤、血管畸形及肿瘤血管进行病变诊断及术前、术后评价；其次是近年出现的逐层减影、半自动数字减影、匹配蒙片骨去除法及控制球管曝光点的减影等去除颅骨的减影技术，没有颅骨的干扰血管显示更加清楚，血管与病变关系显示更准确。

Critical levels of external and internal cadinium exposure resulting in impaired uriniferous tubule funcfion of women and its relation to urine cadmium low molecular albuminuria and other biochemical indexes were proposed based of study on health effects of environmental cadmium pollution to residents living in Zhangshi irrigation area in several years.

本文根据张士灌区镉的环境污染对居民健康影响的多年研究，提出了镉的内、外暴露水平和对人群肾小管损伤的＂临界值＂以及镉与尿低分子蛋白等多项生化指标的健康效应关系，并通过超＂临界值＂频率和接触归因危险性评价提出了环境慢性镉危害早期判断标准的初步建议。

The first case is the variable depth with a fixed notch-width and the second case is variable width with a fixed notch-depth. It can be observed fromthe moment-curvature curve of the first case that the magnitude of the moment is larger for the deeper depth than that for the shallow depth.

由有限元素ANSYS 分析结果可以观察出，在控制固定曲度做循环弯曲负载时，弯矩－曲度曲线图显示出，在固定凹槽的宽度，当深度较浅时，达到设定的控制曲度所需施加的弯矩相对於凹槽深度较大的圆管要大的多。

In my eyes, these things certainly are NOT arts, and I feel they are insults and humiliations to the ART and, more importantly, they are huge disrespects and insults to millions of the victims and their families and offspring.

而展出的版画多是描绘中日甲午战争及日俄战争，当中有大量日军残杀中国人的斩头处决场面，十分血腥。另一版画中的人物，则有自尽身亡的清朝北洋海军提督丁汝昌，以及战死的「致远号」管带邓世昌。

Pipe heat causes linesr expansion and rurtherresult in tensile stress in the direction of pipe xale to make cracks in direction perpendicular to the axle,in the case ,the stress value is obtained by ormula=E,and if ,it is estimated with 15mm LG PEX-A Pipe as base,the sectional breaking rorce is estimated approx.7.6kg/cm2,being much more little comparing with the concrete bearing force=1,536kg/cm2and its not needed to be anxious to concrete cracking rising.

由于管子的线性热膨而使管子受轴向伸长力，从人在与管轴成直角的方向上产生裂缝，这时的应力接计算，PEX－A按直径15mm标准计算进断面破坏强度约为7.6kg/cm2，比混凝土的支持力1.58kg/cm2小得多，所以不需要考虑管子对混凝土的破坏作用。

March 1960, the Secretary for the successful development of a charcoal powder as the main raw materials of "603" drug-free carburizing agent for liquid carburizing, a domestic initiative and promote the use of the country, replacing imported products. 1978, the Division I-IF heat treatment of geological drilling results, the General Assembly by the National Science and Technology Award. November 1983, held in Shanghai in the third international material, heat treatment, when there are several hundred Chinese and foreign experts to the Division I visited. 1986, I was the Secretary for the first heat treatment in the production license. 1987, Secretary of precision gear chemical heat treatment projects, scientific and technological progress in the third place. 1989, I was named Division II national enterprises, is the same industry in the first. 1990, the multi-sensor film coating mouth heat treatment results in the revitalization of the first prize.

1960年3月，我司研制成功了以木炭粉为主要原料的&603&无毒渗碳剂，用于液体渗碳，属国内首创并在全国推广应用，取代进口产品。1978年，我司的地质钻管中频热处理成果，获全国科技大会奖。1983年11月，在上海召开的第三届国际材料热处理年会时，有几百名中外专家到我司参观。1986年，我司获市首批热处理生产许可证。1987年，我司的精密齿轮化学热处理项目，获市科技进步三等奖。1989年，我司被评为国家二级企业，是全国同行业中的第一家。1990年，感应胶片的多层涂布嘴热处理成果获市振兴一等奖。

For bulk carriers, the side shell is one of the weakest parts of the hull. Most of previous bulk carriers are single-hull bulk carriers, according to the casualty statistics of bulk carriers, the accident rate of the side shell of the single-hull bulk carriers is highest among hatch, pipe, deck, side shell and bottom etc.

散货船的舷侧结构是整个船体结构中最薄弱的环节之一，目前绝大多数散货船为单壳结构，根据多年的散货船事故统计显示，在舱口盖、管系、甲板、舷侧外板、船底结构等诸多损伤中，单壳散货船的舷侧外板事故率是最高的。

The detection is based on the change of electrode potential before and after the antigen-antibody reaction.

蛋白A为抗原和抗体的反应提供了合理的基础，纳米金的存在提高了抗体在电极表面的固定量，多壁碳纳米管促进了电子的传递，从而缩短电极的响应时间。
