过程链管理--用于制定和管理转型组织的工具

在当今企业环境日益复杂而活跃的背景条件下，企业需要不断进行重组和迅速转型。这要求企业要具备更强的适应性和更高的灵活性。为了确保实现这些动态的要求，企业必须制定和实施新型的组织形式。本文介绍过程链管理——一种面向过程进行转型的工具。本文首先简要说明了过程链管理应用的工具、过程链管理的任务和构造。它的出发点是由行动、结构、资源、和指挥所组成的过程链管理。在第二步骤中，重点阐述了客户取向这个过程链管理中最重要的取向量。总体来说，整个价值创造链及与此相关的内部交换关系都具有重要意义。在对过程链管理的方法进行了说明以后，提出了一个应用实例，该实例不仅描述了垂直重构，也对水平重构进行了描述。     

纳米SiO_2与有机物分子的亲和性和分散性

介绍纳米SiO2的合成和粒子表面的粗糙形貌以及纳米粒子链具有类似高分子链的弹性力学属性,研究纳米SiO2的亲合性,探讨亲合性对纳米SiO2的分散、改性、应用的影响。研究表明,在极性外加剂(如乙二胺、乙二醇、PEG、PDMS、PTHF、PMMA、PBMA等)存在的情况下,纳米SiO2的弹性粒子链和硅烷醇对SiO2的分散和改性具有显著的影响。带有大烷基侧链的高分子链与SiO2表面的亲合能较低,而带有官能团的高分子链与SiO2表面具有较高的亲合性。     

Water‐Stable,Magnetic Silica–Cobalt/Cobalt Oxide–Silica Multishell Submicrometer Spheres

A method to produce monodisperse magnetic composite spheres with diameters from less than 100 nm to more than 1 μm in water solution is reported. The spheres consist of a dielectric silica core and a cobalt/cobalt oxide shell which can be protected from further oxidation with an outer shell of silica or, alternatively, they can be covered with the polymer polyvinylpyrrolidone as a stabilizer. The formation of a uniform magnetic shell proceeds with the adsorption of metallic cobalt seeds, produced by the reduction of cobalt chloride with sodium borohydride, on a self‐assembled layer of polyelectrolytes on the silica core. In the second step, an outer silica shell can be formed by the hydrolysis and condensation of (3‐aminopropyl)trimethoxysilane and tetraethoxysilane. The double‐shell composite spheres show excellent sphericity, monodispersity, and a magnetic hysteresis loop at room temperature.     

小波变换用于影象分割的研究

将近年来兴起的小波理论应用于影象分割技术，提出了一种基于影象直方图小波变换的影象分割方法，并从理论上给出了使用该法所得分割门限的物理意义。实例表明，这种由粗到细引导的多分辨率分析方法，对于复杂影象的分割具有较强的鲁棒性和有效性，克服了传统分割方法中的参数需要人工确定的缺点。

对等张力链条机构设计的再思考

为解决震源在振动器提升后链条与销轴的断裂问题,应采用等张力原理对链条提升机构进行改进设计。经野外实践证明,这种机构基本上能够满足野外工作的要求。本文对目前所采用的机构形式可能存在的改进设计进行了分析。     

长25-29井卡钻事故的处理

长２５－２９井在完井阶段通井过程中发生粘附卡钻事故，在处理卡钻过程中又发生卡套铣筒、井漏、溢流等事故及复杂情况。通过对井下情况的认真分析，采取先堵漏后循环再解卡的处理方案，顺利地解除了该次卡钻事故，大大地减少了经济损失。     

APPLICATION OF THE POLYMERASE CHAIN REACTION TO THE RAPID ANALYSIS OF BREWERY YEAST STRAINS

The rapid discrimination of closely-related Saccharomyces cerevisiae strains can pose a significant problem to breweries, in particular where closely related strains are being used simultaneously to manufacture different products. In this study, two PCR approaches have been examined to assess their usefulness for the discrimination of brewery ale and lager yeast strains. PCR using arbitrary primers (RAPD PCR) was found unsuitable for such an application since the DNA profiles generated from brewery strains were generally found to be identical, due presumably to the close genetic relatedness of these yeasts. In contrast, PCR using δ sequence primers could rapidly differentiate between many ale and lager strains and characteristic profiles for these were generated. This method could also be applied directly to yeasts isolated from brewery worts or from active dried yeast preparations. Results of such analyses were available within the working day.
