梦想不再遥远

从两湖总督张之洞１８９０年创建汉阳铁厂开始，粗略算起来，中国钢铁工业也有百余年的历史了。回首百年，谁能设想，如今连年钢铁产量雄居世界第一的中国，曾几何时，当初却连一根小小的铁钉都要靠外国的轮船运来，所以普通的铁钉被称为“洋钉”。作为最先使用铸铁和用生铁炼钢的东方古国，却在近代饱受外来侵略势力的“船坚炮利”之苦。旧中国冶金工业的落后，导致了国力的极度衰落。新中国成立后，开始了中国钢铁工业的真正起步和起飞，这当中有过３年“大跃进”的失败，也有过１０年“文化大革命”的破坏，尽管如此，经过艰苦创业，在改…     

钢铁企业管理的发展与提升

新中国成立60年来，我国钢铁工业实现了跨越式发展，不但年产钢量达到5亿吨规模，占世界粗钢产量的比重上升到38％，而且钢铁企业的管理水平与工艺技术装备水平也有了极大提高，其中大型钢铁企业的主体装备水平已达到国际水平，有些甚至属于国际领先水平。     

中国钢铁工业发展的新阶段——在2005年中国钢铁工业产业链战略发展与投资峰会上的讲话

目前,中国钢铁工业发展到了一个新的阶段,我个人认为这个新阶段至少有以下四个特征:一、钢铁产量由高速增长将转入适度较快增长从2001年到2005年,也就是在“十五”期间,中国钢铁工业总投资是“一五”到“九五”(1953-2000年)48年钢铁总投资(5200多亿元)的1.3倍。今年钢铁工业总     

拓展大视野 放眼新世纪

进入１９９９年，我国钢铁工业已有了百年发展史，在新中国建立后也已经走过了５０年的发展历程，如今正意气风发地迈向新世纪。百年沧桑，半个世纪的奋斗，钢铁工业取得的成就令世人瞩目。在新世纪来临的时刻，钢铁工业面临着重大的抉择。钢铁企业目前需要冷静地审视国内...     

标杆比对战略提升大型钢铁企业市场竞争力的创新实践

鞍钢是新中国第一个恢复建设的大型钢铁联合企业和最早建成的钢铁生产基地,被喻为“中国钢铁工业的摇篮”和“共和国钢铁工业的长子”。90年代初期,随着我国市场经济体制的确立,钢铁产品由过去的“统购包销”、“黄帝的女儿不愁嫁”,逐渐向市场竞争转变。面对市场竞争、价格下跌,鞍钢缺乏应对能力,1997年至1999年生产经营靠不断下调折旧率才勉强维持全年利润八千万元水平,主要生产技术经济指标长期落后,

提高冶金装备水平为钢铁工业持续、稳定、协调发展做贡献——冶金部副部长殷瑞钰在1991年全国冶金机动工作会议上的报告

一、“七五”期间机动工作的主要成绩 “七五”期间,是钢铁战线改革开放、积极进取的五年,是钢铁工业进步快、变化大,蓬勃发展的五年,是我国钢铁工业发展过程中的一个重要时期。“七五”期间,也是冶金装备水平有显著提高,维修设备、治理隐患取得成绩,保证安全生产的五年,推行现代化设备管理初见成效的五年。全国冶金企业设备战线广大职工,为钢铁工业持续、稳定、协调发展作出了重要贡献。     

中国钢铁工业发展的回顾、展望和思考

简要回顾了中国钢铁工业“十一五”的发展,五年里中国钢铁工业产能、产量快速增加,调整产品结构、转变发展方式、提高综合竞争力取得很大成绩,但是发展的“瓶颈”日益突显。对未来几年中国钢铁工业的发展做了展望,预见经过今后五年的努力,中国钢铁工业将在“十一五”发展的基础上,通过转方式、调结构,在新的历史起点上实现新的更好的发展。最后,还就中国钢铁工业的快速发展提出了一点思考。     

在锰矿贫化条件下节焦增产的一些体会

经过无产阶级文化大革命,结束了钢铁工业“十年徘徊”的局面。在钢产量增长的同时,高炉锰铁也有了巨大增长,但是,目前锰矿的采、选还赶不上冶炼发展的要求,因而,出现了矿石贫化趋势。这种趋势目前仍在继续,已成为影响锰铁生产发展的一个突出问题。我厂入炉锰矿品位60～61年为25%左右,

Results of treatment of cancer of the cardia

Cancer of the cardia is traditionally discussed with cardiac cancer of the lower portion of the esophagus and upper gastric cancer invading the esophagus, and the specific characteristics of cancer of the cardia have never been clearly defined. We reviewed the outcome of 172 patients with adenocarcinoma of the cardia who had undergone radical surgery between 1949 and 1994 in the Division of Gastrointestinal Surgery of the Cancer Institute Hospital. The centers of the tumors were located within 2 cm above and below the boundary between the esophagus and the stomach, and their longitudinal diameter was less than 8 cm. We divided the patients into an early period (1949-1979; n = 79) and a late period (1980-1994; n = 93), and focused on the historical transition. There were no differences in patient gender or histology between the two periods. However, the late period was associated with fewer cases of esophageal invasion and shorter longitudinal diameter, as the age of the population advanced. The number of advanced cancers such as the localized and infiltrative type had decreased, and early cancer and early clinical stage had become more common, but despite the fact that the number of early cancers had increased, extended dissection, such as thoracic and paraaortic lymph node dissection, was performed more frequently. By clinical stage, the long-term outcome markedly improved in Stage I patient in the late period, and tended to improve in Stage II and III patients. This appears to have been attributable to the prevention of micrometastasis by extended dissection, although the number of early cancers is another major potential cause. There were no differences in the outcome of Stage IV patients between the two periods, and further advances in multimodality therapy must be awaited. The range of resection is basically proximal gastrectomy, and if there are adequate indications, the prognosis is favorable. In view of the status of lymphatic flow and lymph node metastasis, and long-term results, lateroaortic lymph node dissection is important. Since the number of early cancer patients has been increasing, if intraabdominal recurrence is prevented, intrathoracic lymph node dissection will contribute greatly to the outcome of such patients.     

The effect of amount of possession of the trait of hostility on accuracy of perception of hostility in others.

Some theories of personality hold that an individual's perception of others is influenced by his own personality characteristics; more specifically, that a trait of low social value will be projected more into others, and that insight into the possession of these characteristics reduces this distortion. These 2 hypotheses were tested by having a group of college students rate each other (including themselves) on degree of friendliness or hostility. Agreement with group rating about self yielded the insight score. In general, the hypotheses were supported; the "friendly" Ss were most accurate in their perception of others, and insight was positively associated with accurate perception.

Comparison of rates of infection of two methods of emergency ventricular drainage

The rates of infection of two methods of external ventricular drainage in use at Atkinson Morley's Hospital--namely, (a) percutaneous drainage with Rickham reservoirs and (b) tunnelled ventriculostomies--were compared in this retrospective review. Percutaneous drainage of CSF with Rickham reservoirs was associated with a 27% rate of infection as identified by positive microbiological cultures; tunnelled ventriculostomy catheters had a 10% infection rate. The difference in the infection rate between the two methods was statistically significant (P < 0.015). Other variables examined, including the age and sex of the patients and the reasons for ventricular drainage, were not associated with an increased rate of infection. Most infections from either method were caused by a coagulase negative staphylococcus. The average duration of ventricular drainage before identification of positive cultures was 5.7 days for Rickham reservoirs and 6.0 days for ventriculostomies.

Effect of antibiotics of chemotaxis of human leukocytes

The effect of 20 different antibiotics on chemotaxis by human neutrophils was studied. Human leukocytes incubated with chloramphenicol, rifampin, sodium fusidate, and tetracyclines in vitro showed markedly depressed migration. The mechanisms by which these antibiotics affect leukotaxis are discussed.
