基于VB解初等超越方程的一种精确算法

将超越函数用其幂级数展开式的前n项和近似代替,将超越方程的求解转化为代数方程的求解问题,避免了很多复杂的数学计算.文章结合二分法基于VisulBasic6.0语言编写了求解代数方程的程序,其求解精确度远远高于用Mathmatica计算软件所计算的结果.     

Organising international supplier relations: An exploratory study of Western purchasing in China

This paper analyses Western purchasing in China in order to investigate the motives for sourcing, the specific requirements of the area and, in particular, the base and features of supplier relationships. It reports recent experiences of seven companies based in Finland, including two global companies, two units with foreign ownership and three Finnish SMEs. Prevalent in Chinese sourcing are long-term supplier relations, but no partnership relations have been established. The companies build their supplier relations gradually and they all emphasise a long-term viewpoint to Chinese sourcing. Commitment of the Chinese partner is a key challenge, overcoming of which would help companies to avoid and solve, e.g. quality problems. The study shows that, for the Western supply personnel, key competences and tools for bridging the psychic distance are social skills and interest in the Chinese culture.

我国中小企业信用担保体系存在的问题与对策

融资难一直是制约中小企业发展的瓶颈。解决的关键是建立中小企业信用担保体系。我国目前中小企业信用担保体系处在初级阶段,功能十分有限。在进一步规范、做强、做大信用担保机构的基础上,尽快建立体系完善、功能强大的中小企业信用担保体系,提供更多的融资支持,提升中小企业竞争力和发展活力,带动国民经济发展,已成为当务之急。     

论公司财务的价值创造功能

生产要素经过市场交易过程被企业购入之后,变为要素资本;各种要素资本的价值及其增值形成企业的财务价值。决策人的要素资本偏好结构是根据个人偏好对方案集合中的方案进行对比并区分优劣或大小,最终排列各方案的优劣次序。为了描述决策人对确定性后果的偏好程度,应建立序数价值函数、可测价值函数和财务效率等概念,从而建立要素资本价值函数,找出公司财务创造价值的机理。

On estimating the reliability after sequentially estimating the mean: The exponential case

Sequential estimation problems for the mean parameter of an exponential distribution has received much attention over the years. Purely sequential and accelerated sequential estimators and their asymptotic second-order characteristics have been laid out in the existing literature, both for minimum risk point as well as bounded length confidence interval estimation of the mean parameter. Having obtained a data set from such sequentially designed experiments, the paper investigates estimation problems for the associatedreliability function. Second-order approximations are provided for the bias and mean squared error of the proposed estimator of the reliability function, first under a general setup. An ad hoc bias-corrected version is also introduced. Then, the proposed estimator is investigated further under some specific sequential sampling strategies, already available in the literature. In the end, simulation results are presented for comparing the proposed estimators of the reliability function for moderate sample sizes and various sequential sampling strategies.     

西方空间集聚—扩散理论及北京城区功能的扩散

已被世界上许多国家区域经济发展实践验证的西方空间集聚一扩散理论，是对区域经济发展中带有普遍性特征规律的理论表述。以这一理论为基础，结合北京城区集聚不经济的实际，加快北京城区工业企业、事业单位和与此相伴的住宅、商业用房、交通枢纽、第三产业的择情扩散，保证有效扩散的法律、税制、规划、政府职能、中小城镇、乡镇企业的发展和网络建设等相关环境的建设步伐，是促使北京作为国家首都、世界城市、文化名城、宜居城市功能有效发挥和提升京津冀区域经济合作等级的重要步骤。
