铸造高硅不锈钢在浓硫酸介质中的钝化膜研究

采用表面分析技术，研究了铸造高硅不锈钢在９８％Ｈ２ＳＯ４、０℃介质中，表面膜中元素分布及腐蚀行为与其元素所处价态的关系。试验结果表明，高硅不锈钢在浓硫酸中，表面膜因抗蚀作用不同可分为三层，表面层、中间层和过渡层。表面层及中间层都具有抗腐蚀能力，可阻挡介质对不锈钢基体的浸蚀，中间层中富集硅和铬，主要以ＳｉＯ２和Ｃｒ２Ｏ３形式存在。而镍富集在过渡层中，可进一步提高膜的稳定性。

取向电磁钢板高温退火初期采用Ar气作为保护气氛对镁橄榄石被膜质量的影响#br#

高温退火低保温期，采用惰性气体作保护气体能改善被膜质量。惰性气体Ar与H2、N2相比黏度高， Ar气难于侵入钢卷的各层间挤压出水分子，水分子就在钢板层间保持下来，将会进一步促进被膜的生成。之后导入氢气，促进了退火隔离剂MgO的表面活化性，由于钢板层间是湿氢保护气氛，钢板表面的副氧化层中、难于被还原的Fe2SiO4，将与MgO发生反应，生成Fe2 xMgxSiO4，又继续形成完善的Mg2SiO4镁橄榄石被膜，在这种条件下所生成的被膜将吸收隔离涂层中的Ti，增强了被膜的强度。

硫化廿二酸钼的合成及其摩擦化学研究

通过低温硫化工艺和复分解反应合成了硫化廿二酸钼，并在四球机上考察了硫化廿二酸钼的摩擦学特性。实验结果发现硫化廿二酸钼的抗磨极压性超过了目前国内外传统的抗磨极压剂硫化异丁烯（Ａｎｇｌａｍｏｌ３３），二烷基二硫代磷酸锌（ＺＤＴＰ），以４００＃中性油作基础油，四球磨斑直径ｄ３９２Ｎ３０ｍｉｎ依次为０．５６ｍｍ、０．６２ｍｍ和０．８２ｍｍ，最大无卡咬负荷ＰＢ值相应为１１７６Ｎ、１１２７Ｎ和９８０Ｎ，摩擦系数ｆ值比基础油下降了４０％。用俄歇能谱（ＡＥＳ）分析了摩擦表面膜，发现在表面深层为５０处富含硫和钼，并在该处两者都达到了峰值。据此认为硫化廿二酸钼的减摩、抗摩和极压作用机理是在摩擦表面生成了ＦｅＳ（或ＦｅＳ２）和层状结构ＭｏＳ２的复合无机膜，由于复合膜和ＭｏＳ２层的扩散渗硫、渗钼作用，增强了复合无机膜的强度，同时由于复合无机膜和ＭｏＳ２层在摩擦时的相对滑移作用，使硫化廿二酸钼具有减摩、抗摩和极压功能。此外，还提出了润滑膜的结构模型。     

含铬铸钢在混合盐中腐蚀行为的研究

对不同成分的含铬铸钢进行了与电化学试验，利用恒电位仪、扫描电镜和ＸＰＳ手段，研究了试验材料在混合盐（０．１％ＮａＣｌ＋０．５％Ｎ２ＳＯ４＋Ｈ２ＳＯ４，ｐＨ＝６）中的抗蚀行为，试验表明铬含量对铸钢耐蚀性有显著的影响。当含理达到８％以上，铸钢表面形成了氧化膜。氧化膜富氧、富铬而贫铁，膜中的Ｃｒ／Ｆｅ比远大于基体中的值；膜的表层含有铬与铁的氢氧化物和氧化物。这种氧化对含铬约８％的铸钢起到了保护作用。

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.

Concept of freedom of infection of animal flocks

Totally negative results of epidemiological investigation of random samples do not prove the absence of the infection as the pathogen may be restricted to only a few animals in the herd for a long time. The statement "absence of infection" is critical for such situations. The question is raised, whether the statement "absence of infection" should be generally avoided. Classification of herds and flocks according to the prevalence of the pathogen would be more valid for the implementation of control measures.     

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.
