竞技体育赌博的法经济学分析

法经济学分析表明,赌徒、庄家以及运动员和裁判参与竞技体育赌博的原因并不完全相同。赌徒是为了满足其爱好风险的需要,庄家纯粹为了获利,而运动员和裁判虽然也是为了获利,但在很多情况下是被庄家引诱而为之。因此,治理竞技体育赌博必须改变赌徒对赌博的态度,并加大查处力度,使其无利可图。

结合国家防汛抗旱指挥系统二期工程浅谈如何做好水利信息化监理工作

加强监管是做好水利信息化监理工作的核心,勇于担当的精神是监理加强监管的动力源泉。本文主要从监理在水利信息化项目的招标、设计、实施、验收四个阶段,采取“四控三管一协调”即质量控制、进度控制、成本控制、变更控制、信息安全、合同管理及知识产权管理、信息管理和组织协调的监理工作模式,并结合国家防汛抗旱指挥系统二期工程监理工作实际情况,浅谈如何做好信息化监理工作。     

Molecular design revitalizes the low-cost PTV-polymer for highly efficient organic solar cells

Developing photovoltaic materials with simple chemical structures and easy synthesis still remains a major challenge in the industrialization process of organic solar cells (OSCs). Herein, an ester substituted poly(thiophene vinylene) derivative, PTVT-T, was designed and synthesized in very few steps by adopting commercially available raw materials. The ester groups on the thiophene units enable PTVT-T to have a planar and stable conformation. Moreover, PTVT-T presents a wide absorption band and strong aggregation effect in solution, which are the key characteristics needed to realize high performance in non-fullerene-acceptor (NFA)-based OSCs. We then prepared OSCs by blending PTVT-T with three representative fullerene- and NF-based acceptors, PC₇₁BM, IT-4F and BTP-eC9. It was found that PTVT-T can work well with all the acceptors, showing great potential to match new emerging NFAs. Particularly, a remarkable power conversion efficiency of 16.20% is achieved in a PTVT-T:BTP-eC9-based device, which is the highest value among the counterparts based on PTV derivatives. This work demonstrates that PTVT-T shows great potential for the future commercialization of OSCs.

浪漫太阳岛

20多年前,著名歌唱家郑绪岚一首《太阳岛上》,把哈尔滨太阳岛的美名传遍了天下。太阳岛成为人们美好情怀的一种寄托。躲不开岁月的追忆,躲不开罗曼蒂克的怀恋,到了哈尔滨,就躲不开太阳岛。     

青铜蟠龙盘之谜

1984年3月17日,温岭县琛山乡莞渭童村村民童守根冒着早春的寒意,来到附近下望头山半山腰。他为父亲挖墓穴,挖着挖着,在挖至距地表约50厘米时,突觉碰到了坚硬的异物。顺势再挖,发现了一件巨大的青铜器,像个脸盆,全身布满精细的花纹,古色古香,更奇的是中间还雕着一个龙头,闻所未闻,见所未见。童守根不知道这是什么东西,

长枞水电大坝的热弹性与渗漏分析

This paper deals with the temperature and displacement fields of the top mid-block of south transition at Long Spruce Generating Station, in the North of Manitoba, Canada. According to the experimental results of Manitoba Hydro in the past two years, the top mid-block is assumed to be a rectangular one that has two supposed temperature distributions at its boundary sides. Then, the temperature fields for the top mid-block are obtained from the analytical solutions by separation of variables. By using the analytical solution of temperature field, the displacement behavior of the top block in various temperature fields is discussed in details. The numerical results are given to show the causes of the leakage between the top mid-block and the dam. Finally, the repair methods for leakage are discussed for practical leaking repair and its engineering applications.
