工业铁水脱硫的改进

在二十世纪60年代按照国家冶金工业科学研究设计院（哈尔科夫市）的设计，亚速钢厂已建了一个同时用5个铁水罐车的铁水炉外处理装置。设备装配了石灰储料罐，喷枪移动装置，取样器和辅助装置。那时还没有往铁水下面送脱硫剂的有效操作装置。石灰是用竖炉生产（煅烧时石灰有9％的损耗量，即21％未焙烧的石灰石），且用球磨机磨碎并掺合～5％颗粒渣以消除结块。     

铁钢界面铁水罐多功能化技术中的尾罐效应

 针对钢铁制造流程铁钢界面铁水罐多功能化技术中存在的尾罐问题,首先系统阐述了尾罐现象产生的原因及其度量,随后提出尾罐效应的概念并从统计学角度分析了尾罐效应的数学特征,最后根据首钢京唐钢铁公司铁钢界面生产实绩数据,对铁水罐多功能化技术中的尾罐效应进行实证研究。结果表明,首钢京唐某月尾罐率为29.45%,尾罐效应主要体现在尾罐运行时间的延长、到站铁水温度的降低,以及由此带来的转炉氧气消耗量的增加等方面,铁水罐非尾罐和尾罐的受铁时间和周转时间均值分别相差81和42 min,KR脱硫站进站、脱磷转炉兑铁和脱碳转炉兑铁的铁水温度均值分别相差27、22和24 ℃,脱磷转炉和脱碳转炉的氧气消耗分别相差109和199 m3。

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.
