基于差异信息量的多源数据融合方法

D-S证据理论可应用于多源数据融合领域，但在处理高度冲突的证据时，可能会出现反直觉的结果.为解决这一问题，本文提出了差异信息量的概念及融合方法.首先，通过信息熵表明证据的相对重要性，采用散度获取证据可信度.然后利用证据可信度优化证据差异度以得到差异信息量，经过计算获取数据的最终权重，并将其作为D-S证据理论中的基本概率分配进行决策.在处理冲突证据、一致证据及不同数量证据等方面的数据融合问题时与其他方法对比，所提方法收敛更快，准确度更高.故障诊断的应用实例表明，所提方法的不确定性更小，优于现存的其他方法.     

General mechanisms of drought response and their application in drought resistance improvement in plants

Plants often encounter unfavorable environmental conditions because of their sessile lifestyle. These adverse factors greatly affect the geographic distribution of plants, as well as their growth and productivity. Drought stress is one of the premier limitations to global agricultural production due to the complexity of the water-limiting environment and changing climate. Plants have evolved a series of mechanisms at the morphological, physiological, biochemical, cellular, and molecular levels to overcome water deficit or drought stress conditions. The drought resistance of plants can be divided into four basic types-drought avoidance, drought tolerance, drought escape, and drought recovery. Various drought-related traits, including root traits, leaf traits, osmotic adjustment capabilities, water potential, ABA content, and stability of the cell membrane, have been used as indicators to evaluate the drought resistance of plants. In the last decade, scientists have investigated the genetic and molecular mechanisms of drought resistance to enhance the drought resistance of various crops, and significant progress has been made with regard to drought avoidance and drought tolerance. With increasing knowledge to comprehensively decipher the complicated mechanisms of drought resistance in model plants, it still remains an enormous challenge to develop water-saving and drought-resistant crops to cope with the water shortage and increasing demand for food production in the future.

高考走向的争鸣与思考

高考走向何方,成为人们热议的话题。有人主张废除高考,有人反对废除,主张改革;有人赞成统一高考,有人赞成高校单独招考……笔者认为高考要改不宜废,但改革要考虑国情,要遵循一定原则,要有比较稳定的思路,要有灵活应变的策略和科学的方法。     

煤矿生产中对地质资料的再认识

从测量、地质、钻探、煤矿三大害、煤质成果、地质资料评价等方面阐述了地质资料对煤矿生产的重要性，指出对地质资料的再认识，就是为了将地质资料去粗取精，确定其中能够为我所用的部分，以更好地为生产服务，并在矿区做下一步勘探工作时能够有的放矢，以最少的资金投入，达到最佳目的。     

Hamilton线图中的泛圈性

对于图Ｇ的边ｅ＝ｕｖ，定义ｄ（ｅ）－ｄ（ｕ）＋ｄ（ｖ），这里ｄ（ｕ）和ｄ（ｖ）分分别表示ｕ和ｖ的度，该文的主要结果是：对阶为ｎ（ｎ≥４０）的简单连通图Ｇ，如果对Ｇ中任意两条边距离为２的边ｅ１，ｅ２都有ｄ（ｅ１）＋ｄ（ｅ２）≥ｎ，并且线图Ｌ（Ｇ）是Ｈａｍｉｌｔｏｎ的，则Ｌ（Ｇ）是泛圈的，并且条件Ｌ（Ｇ）是Ｈａｍｉｌｔｏｎ是必要的。     

并行工程产品开发过程的建模方法学

在并行工程中，为了实现产品开发过程的集成、并行和最优化，首先要建立能够充分反映产品开发过程各方面信息的产品开发过程模型。通过对模型的仿真分析和优化，指导产品开发过程的实施。本文首先提出了并行工程产品开发过程模型是集成多视图模型，随后提出了采用集成多视图建模理论的并行工程产品开发过程建模、分析和管理的方法学框架
