中国钨加工业“十二五”发展的思考

中国是钨资源大国,但还不是钨工业强国。钨加工制品是国防军工和现代制造业的重要功能材料。重点发展高技术含量、高附加值的高档钨加工产品,加快研发具有自主知识产权和国际竞争力的知名品牌产品,推进产业结构调整和产品优化升级,推动钨资源整合和钨企业集团化发展,提高中国钨加工业的整体经济实力和国际竞争力,是"十二五"期间中国钨加工业的重要战略任务。

结构调整 技术换代 产业升级──在冶金部1998年炼钢轧钢工作会议上的讲话

这次将炼钢轧钢合起来开会不仅仅是为了精简会议，主要是从整体上对科技进步进行思考，进行整体流程的结构优化，目的是为了调整企业结构，调整和优化产业结构，增强企业和行业的市场竞争力。我觉得结构优化主要是由市场需求来引导的，结构优化又是由科技进步来推动的，市场需求的引导是产品结构的优化调整，装备水平的优化，但靠的是技术换代。所以我认为，我们现在遇到的问题是市场竞争力的问题，市场竞争力应该这样下定义：就是在国际自由贸易的条件下（不能有关税壁垒、政府补贴），某个产品、某个企业、某一个产业所具有的开拓市场、占…

中国铜工业的2010

2010年，中国铜工业回升向好基础逐步巩固，趋向平稳较快发展，行业整体实力和国际影响力、竞争力逐步增强。但行业面临冶炼产能增长过快，产业集中度过低等问题亟待解决。2011年，铜业要转变发展方式和优化产业结构，使中国铜工业健康有序发展。     

加入WTO与马钢的对策

面临经济全球化的国际竞争,马钢现状还不适应加入WTO的新形势。马钢首先要有高技术含量、高附加值的钢材产品,为此必须加快工艺技术装备结构的调整,实现产品结构的升级和优化,加盟具有国际竞争力的钢铁企业集团,发挥规模优势,同时,还应建立相应的国际市场机制的经营模式,进一步提高马钢的核心竞争力。

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.     

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.     

Quality of life of relatives of mental patients

Usage of quality of life of psychiatric patients' relatives as the parameter of estimation of the quality of psychiatric care is considered. By means of standard questionnaire elaborated by the authors as well as by means of both individual and group conversations the quality of life was analyzed in 40 relatives which lived together with psychiatric patients. Different spheres of their life and difficulties (financial, social-psychologic, production) were examined in families with such patients. The defects of psychiatric care that had direct influence on the quality of life of the psychiatric patients' relatives are outlined.     

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.
