聚合物驱采油污水增黏稳黏剂SC的研制

针对影响污水聚合物溶液初始黏度和稳定性的主要因素,从消除或降低其对聚合物溶液影响的角度,研制开发出了既能较大幅度提高聚合物溶液初始黏度又能使黏度保持相对稳定的采油污水增黏稳黏剂SC.孤东油田采油污水经SC处理后配成1500mg/L聚合物溶液,初始黏度提高38%以上,略高于清水配母液污水稀释聚合物溶液,40d后的黏度比污水、清水聚合物溶液分别高出85.9%和61.2%.SC处理采油污水后可以代替清水配制聚合物溶液.

The Geographic Information Grid System Based on Mobile Agent

We analyze the deficiencies of current application systems, and discuss the key requirements of distributed Geographie Information serviee （GIS）, We construct the distributed GIS on grid platform. Considering the flexibility and efficiency, we integrate the mobile agent technology into the system. We propose a new prototype system, the Geographic Information Grid System （GIGS） based on mobile agent. This system has flexible services and high performance, and improves the sharing of distributed resources. The service strategy of the system and the examples are also presented.     

Genetic models in brain and behavior research,part IV

Four reviews on the the role of developmental factors in hypertension are introduced and set in historical context. Recent research in the laboratory rat has shown that the preweaning environment makes an important contribution to the level of blod-pressure reached in adult life in genetic models of hypertension. Both of the most commonly used models of hypertension, the SHR and SS/Jr rat strains, exhibit lower BP in adult life, if they are fostered shortly after birth to mothers from their normotensive control strains. It has been suggested that it is the idiosyncratic maternal behavior of the hypertensive mothers which contributes to the elevated BP of their offspring, and it has been amply demonstrated that there is an association between a constellation of behaviors emitted by rat mothers and the adult BP of their offspring in a wide variety of genetic groups (inbred hypertensive animals, F1's and F2's). In addition to the above, maternal environment has been demonstrated to have a significant impact on the pathophysiological response of hypertensive animals to a high salt diet. Being raised by an SHR mother, versus an SS/Jr mother, increases the magnitude of BP increases to a high salt diet, susceptibility to hemorrhagic stroke, body weight loss and the risk of mortality. A variety of physiological systems are undergoing rapid change during the preweaning period and may mediate the effects of differences in the maternal environment. These include the renin-angiotensin system and the peripheral sympathetic nervous system. Nutritional factors may be involved in all of the phenomena referred to above. Thus, any physiological mechanisms that are proposed to link maternal behavior to its effects on the physiology of adult animals should recognize the involvement of nutritional factors. Research on the role of developmental factors such as maternal behavior in genetic models of hypertension is at the interface of two growing disciplines: behavior genetics and developmental psychobiology. The methodological and conceptual contributions of these fields to advancing our understanding of these phenomena is emphasized.

聚氯乙烯增塑糊流变行为研究——Ⅲ、稀释剂和分散剂的影响

以石油溶剂为稀释剂,4-甲基-2-戊酮(Ⅰ)和2-乙氧基乙醇(Ⅱ)为分散剂,研究了不同PVC树脂增塑糊的粘度特征。结果表明,由于PVC是极性聚合物,分散剂的分散效果主要决定于它的极性,Ⅰ的分散效果优于Ⅱ。若PVC含有聚氧乙烯基型表面活性剂,其糊用PVC树脂颗粒能较好地分散。
