深循环电动助力车铅酸蓄电池固化内化成工艺

电池内化成较外化成有许多明显的优点,特别是生产周期短、费工少、占地少、环境污染少。但如果采用一般的工艺,不容易化成透彻,因此其深循环寿命明显比不上外化成。通过改进配方和生产工艺,采用特殊的固化工艺,提高电池大电流充电接受能力,采用脉冲内化成减少极化,可以提高效率 30% ～40% ,电池的深循环寿命能达到用户的要求。寿命检测方法不能采用单个电池快速测试 (1　C 充 42　m in,2　C 放 18　m in 为一个循环) 要成组检测 (3 个或 4 个一组),工作电流 5　A 或 7　A 放电(D O D 100% ),否则会得到不同的结果,影响产品质量的认定。     

资本周转的涵义

资本周转是周期性的循环。资本周转与资本循环的区别在于是否从周期性上去考察资本的循环，而不在于资本循环次数的多少。如果从周期性上考察，即使一次资本循环也属于资本周转，离开周期性去考察，即使反复多次的资本循环也不能称之为资本周转。     

从主体性的角度审视道德权利

以主体性的视角，通过对权利、道德权利、道德权利和道德义务关系和道德权利的特点的分析，认为道德权利的研究对传统伦理学的改革；提高人们对道德权利的认识，进而有利于推进新时期的道德建设；促使道德规范由他律向自律转换，增强人们的责任意识，提高人们履行义务的自觉性等等具有十分重要意义。

Limit cycle computation for describing function approximable nonlinear systems with box‐constrained parametric uncertainties

We propose an algorithm to compute the limit cycle set of uncertain non‐rational nonlinear systems with nonlinear parametric dependencies. The proposed algorithm computes the limit cycles for a wide class of uncertain nonlinear systems, where the transfer function of the linear element and describing function of the nonlinear element need to be only continuous with respect to the parameters and continuously differentiable with respect to the amplitude and frequency of periodic input signal. The proposed algorithm guarantees that the limit cycles are reliably computed to a prescribed accuracy, and that none of the actual limit cycle point is missed out irrespective of the tightness of the prescribed accuracy. Moreover, for a prescribed accuracy, the proposed algorithm computes all the limit cycles in a finite number of iterations, and an upper bound for this number is also computable. The algorithm is demonstrated on a challenging non‐rational example with nonlinear parametric dependencies. Copyright © 2005 John Wiley & Sons, Ltd.     

Engineering change management in individual and mass production

The ability to manage engineering changes (ECs) efficiently reflects the agility of an enterprise. A large majority of products become gradually improved and perfected through the developmental-design process, during which the set design requirements are met or even upgraded, thus prolonging the product life cycle. The concept of product improvement was based on the activation and tracking of (ECs) through the developmental-design phase and the manufacturing phase. A special method was used to recognize activities within the process and the degree of involvement of individual participants. The individuals involved in the process were provided with appropriate information and the required communication channels with others were ensured. The EC process was generalized and applied to different types of production. A product's complexity and design level were analyzed first, and key factors such as CE methods, process definition, information system, communication and organization were used as a tool for optimizing the EC process. The method was tested and successfully applied into industrial practice.
