试论高校体育学生长跑训练产生恐惧心理探索

长跑是体育教学中必授项目,同时又是田径教材中的重要内容。为此,以（黎明职业大学为例）大一,大二,大三部分学生进行问卷调查,调查研究了学生在长跑训练时的心理反应。调查结果表明,大学生普遍存在对长跑项目有恐惧心理。对产生恐惧心理的主要原因进行了分析,分析发现产生恐惧心理有主客观多种因素。对此,探索学生的恐惧心理,无疑对长跑训练教学具有重要意义。     

The relationship between exploration and exploitation strategies,manufacturing flexibility and organizational learning: An empirical comparison between Non-ISO and ISO certified firms

The markets in which organizations currently operate require them to use behaviour based on both exploitation strategy and exploration strategy, each of which contributes fundamental benefits for the firm’s success. Exploitation strategy attempts to obtain the maximum advantage from existing abilities, whereas exploration strategy searches for new ways for the organization to adapt. Further, since manufacturing markets are characterized by short product life, they require a high level of manufacturing flexibility, which can play a crucial role in the development of the exploitation and exploration strategies. This study analyses the relationship of manufacturing flexibility to exploitation and exploration strategies, taking into account an issue of maximum international scope: the implementation of ISO standards. In many international markets, ISO implementation is crucial in enabling organizations to be competitive. However, no consensus has been reached concerning the real benefits that these systems provide to the organizations that implement them. The main goal of our study is to analyse whether there are significant differences in the relationship of manufacturing flexibility to exploitation and exploration strategies in ISO 9001:2000 certified organizations and non-certified organizations. Our results show that most of the relationships analysed are only significant in ISO certified organizations. As an added value, the study analyses the relationship of exploitation and exploration strategies to organizational learning orientation and finds this relationship to be significant in all cases.     

深水高渗气井测试设计关键技术与实践

深水气井测试是当今世界油气勘探技术难题之一,工作制度的确定、测试程序的优化、水合物及出砂的防治等问题是其主要难点。通过水合物生成和出砂的临界流量等分析设计合理工作制度,建立测试数值模型确定压恢和探边测试时间,优化测试管串创新形成 “快速清井、低速取样、调产缓变、关井恢复”的一开一关测试程序,在缩短测试时间、降低水合物生成等风险的同时实现二开二关功能,有效指导了LS17-2-1井测试作业顺利进行。测试结果表明测试设计与施工基本一致,达到了准确评价气田的目的,能够为类似深水测试设计提供理论与方法。

Feller Property and Infinitesimal Generator of the Exploration Process

We consider the exploration process associated to the continuous random tree (CRT) built using a Lévy process with no negative jumps. This process has been studied by Duquesne, Le Gall and Le Jan. This measure-valued Markov process is a useful tool to study CRT as well as super-Brownian motion with general branching mechanism. In this paper we prove this process is Feller, and we compute its infinitesimal generator on exponential functionals and give the corresponding martingale. The research of the second author was partially supported by NSERC Discovery Grants of the Probability group at Univ. of British Columbia.     

从岩相古地理论中国南方中下三叠统油气潜景

中下三叠统是中国南方重要的含油气海相碳酸盐岩地层，油气潜力很大，但勘探程度在大部分地区却很低．在定量岩相古地理研究及编图的基础上，对中国南方中下三叠统的烃源岩和储集岩的类型、分布及其与沉积环境的关系，对区域盖层和局部盖层的性质和分布，尤其是对中下三叠统经过多次重大构造变动后所形成的油气保存单元等进行了较深入的研究．指出了５个最有利的油气勘探地区，即绵阳—广元、南充—达县、泸州—重庆、宜昌—沙市、安庆—芜湖地区，以及９个有利的勘探地区和１０个较有利的勘探地区，为我国南方油气勘探打下坚实的基础．
