国有企业落实“三重一大”制度的再思考

"三重一大"制度是国有企业党风廉政建设的切入点。国有企业在落实"三重一大"制度中存在着对制度规定重要性的认识不够、制度过于原则化、可操作性不够等薄弱环节。要落实"三重一大"制度,就必须强化国有企业纪检监察部门组织协调意识;要以制约和规范权力为核心,改革和完善国有企业重大决策制度;要以建立和完善科学民主的干部选拔任用和管理监督机制为重点,改革和完善国有企业干部选拔任用制度;要以规范投资决策行为为立足点,改革和完善国有企业重大投资项目安排制度;要以严格审批、管理和监督为着力点,改革和完善国有企业大额度资金使用制度。     

浅谈带好职工队伍的途径

要想做好职工思想政治工作,提升队伍执行力,只有从单位职工队伍的实际情况出发,抓好"头",才能取得扎实效果。抓好"头",一是要抓好源头,梳理出容易产生矛盾的问题,从制度上公开化、民主化;二是要管好人头,就是做好一人一事的思想工作,划分责任区,明确责任,责任到人;三是要走近心头,就是提倡有情管理,着力推进"家"文化建设,创造和谐的工作、生活氛围;四是要树好领头,就是从抓骨干入手,确立先进分子的模范示范作用。     

关于深化惩防体系建设的实践与思考

坚持以保障企业发展为目标,以构建惩防体系为统领,在指导思想上准确把握"五性",在工作重点上突出增强"五力",在工作目标上着力建立"五制",同时,进一步创新工作理念,增强惩防体系建设的全局性;进一步创新工作方法,增强惩防体系建设的科学性,推进反腐倡廉工作整体发展。     

对构建安全工作信息预警机制的思考

安全连着社会和谐。从某种意义上讲,抓安全就是抓发展,促稳定。加强企业安全工作信息预警机制建设,有助于企业掌握安全生产主动权,打好排除安全隐患主动仗。要做好这一项工作,不仅需要领导重视,部门配合,员工参与,而且需要从制度层面对信息的收集、分析、整理等方面的工作加以规范,确保涉安问题早发现,早报告,早处理。     

Formation mechanism of nano-diamond films from energetic species: From experiment to theory

In this paper, a particular class of nano-diamond films deposited by energetic species is described. Deposition is carried out using the direct-current glow-discharge (DC GD) deposition technique from a methane/hydrogen mixture. In this method, film growth occurs from energetic species being accelerated and incorporated into the film surface. The growth of the nano-diamond film occurs on top of a preferentially oriented graphitic precursor with its basal planes perpendicular to the substrate surface. The nano-diamond films consist of an agglomerate of diamond particles with particle sizes in the 3-5 nm range with amorphous grain boundaries. The hydrogen concentration in the graphitic precursor is only a few percent; however, it increases to ∼15-20 at.% in the nano-diamond film.From a microscopic perspective nano-diamond film and growth from energetic species is explained as a sub-surface process in terms of a four-step cyclic process. The DC GD-deposited nano-diamond films were comprehensively explored by a number of complementary techniques. The hydrogen content and its role in nano-diamond film formation were assessed. The experimental methods used in our studies comprise near-edge X-ray adsorption fine structure (NEXAFS) to prove the short-range coordination of the carbon films and indirectly their phase composition. The surface and grain boundary phase composition were investigated by a combination of electron energy loss spectroscopy (EELS) measured as a function of incident electron energy and hydrogen etching experiments. By transmission electron microscopy (TEM), the micro-structural evolution and their visualization were achieved. The density evolution of the films was determined by X-ray reflectivity (XRR). The hydrogen content and its distribution in the films were studied by secondary ion microscopy spectroscopy (SIMS) and elastic recoil detection (ERD). The hydrogen bonding was investigated by high-resolution electron energy loss spectroscopy (HREELS).Most likely, hydrogen is bonded within the amorphous grain boundaries and saturates the nano-diamond particles. The surface of the films is amorphous in nature.

Genetic algorithms in computer aided design

Design is a complex engineering activity, in which computers are more and more involved. The design task can often be seen as an optimization problem in which the parameters or the structure describing the best quality design are sought.Genetic algorithms constitute a class of search algorithms especially suited to solving complex optimization problems. In addition to parameter optimization, genetic algorithms are also suggested for solving problems in creative design, such as combining components in a novel, creative way.Genetic algorithms transpose the notions of evolution in Nature to computers and imitate natural evolution. Basically, they find solution(s) to a problem by maintaining a population of possible solutions according to the ‘survival of the fittest’ principle. We present here the main features of genetic algorithms and several ways in which they can solve difficult design problems. We briefly introduce the basic notions of genetic algorithms, namely, representation, genetic operators, fitness evaluation, and selection. We discuss several advanced genetic algorithms that have proved to be efficient in solving difficult design problems. We then give an overview of applications of genetic algorithms to different domains of engineering design.
