核磁共振测井在桩1区块底水稠油油藏开发中的应用

针对桩1区块特高含水期底水稠油油藏的开发特点,利用核磁共振测井资料定量评价其孔隙流体流动特性,准确划分产层,直接识别油、水层,准确地评价了区块剩余油分布情况.依此部署了水平井,取得了很好的开发效果.实践证明,核磁共振测井具备常规测井所不具备的某些技术优势,能解决一些特殊的地质问题,有广泛的应用前景.     

A connectionist implementation of the theory of planned behavior: Association of beliefs with exercise intention.

The theory of planned behavior suggests attitudes are a product of salient beliefs. This study examined whether aggregating salient beliefs was plausible within a more biologically centered information-processing environment. A neural network was used to examine associations among beliefs relating to exercise intention. Data on intentions and behavioral, normative, and control beliefs from 114 respondents were used to train (by error backpropagation) a neural network to associate beliefs with intention. The R2 between the network's estimated and self-reported intention was .66. The network's representation comprised 6 belief profiles associated with high, moderate, or low behavioral intention. The neural network accommodated complex relationships among beliefs and belief-intention associations and indicated how high-level constructs such as attitudes may be viewed as the best fit (compromise state) between aroused beliefs.

Assessing Consequences of Substance Use: Psychometric Properties of the Inventory of Drug Use Consequences.

Negative consequences are an important component of the substance use change process, yet no standardized measure exists to assess consequences of use. This study evaluated the psychometric properties of the Inventory of Drug Use Consequences, a self-report measure assessing drinking and drug use consequences. Participants (N=252) were assessed at entry into outpatient substance abuse treatment. Items loaded strongly on 1 factor, and internal consistency of the total scale was high. Fifteen items with the highest correlations with the total scale were chosen to represent the construct. The shortened measure exhibited good internal consistency, convergent and discriminant validity, and detected change over time and may be the measure of substance use consequences that is lacking in the field.

大庆长垣以东古隆起天然气成藏条件的差异性

由长垣以东地区深层天然气分布特征，指出安达—肇州和朝阳沟—肇东古隆起是天然气运移指向和聚集的有利场所。造成安达—肇州古隆起上天然气显示好于朝阳沟—肇东古隆起上天然气显示，前者已获得了大量工业气流，而后者仅见少量气流或显示。但由于天然气在供气条件、储集条件、盖层条件、圈闭条件和运移条件上的差异，造成安达—肇州古隆起本身天然气显示也存在差异，昌德构造、卫星—升平构造和汪家屯构造天然气显示好于模范屯—肇州西构造天然气显示。

Development of intelligent multisensor surveillance systems with agents

Intelligent multisensor surveillance systems consist of several types of sensors, which are installed on fixed and mobile devices. These components provide a huge quantity of information that has to be contrasted, correlated and integrated in order to recognize and react on special situations. These systems work in highly dynamic environments, with severe security and robustness requirements. All these characteristics imply the need for distributed solutions. In these solutions, scattered components can decide and act with some degree of autonomy (for instance, if they become isolated), or cooperate and coordinate for a complete tracking of special situations. In order to cope with these requirements and to better structure the solution, we have decided to design surveillance system control as a multiagent system. This is done by applying an agent-orientated methodology, which is assessed with concrete scenarios.

我国制造业国有企业的现状与发展

制造业国有企业在我国国民经济中具有非常重要的地位,其发展状况因所处地区、行业的不同而存在很大差别。从总体上看,制造业国有企业在投入产出能力、企业运营能力、盈利能力和偿债能力等方面都有待于提高。制造业中大型国有企业保持了良好增长态势。国家重点企业通过增加研究与开发投入,发展后劲显著增强。制造业中国有企业的数量在大幅度减少,其所占的比重持续下降,在制造业的不少小行业中,非国有企业已经取代了国有企业,成为行业中的主要力量。     

Effect of functionalization and boron and nitrogen substitution on some properties of carbon nanotubes

Molecular orbital calculations of the ionization potential of single wall carbon nanotubes having donor NH₂ and acceptor NO₂ groups bonded to the side walls and ends and boron and nitrogen substituted for carbon show substantial increases in ionization potential compared to carbon nanotubes with no functional groups and no carbon substitutions. The presence of a carbon vacancy on the side wall also causes a substantial increase in the ionization potential. The effect of tube length on the ionization energy is also calculated. The calculations also suggest that at appropriate levels of boron and nitrogen doping the armchair carbon nanotubes could be high temperature organic ferromagnetic materials.
