Charge retention increases with the increase of ptfe concentration after the addition ptfe whether in positive electrodes or in negative electrodes or treated by hydrophobic in the surface of negative electrodes 无论是在正极还是负极添加ptfe乳液或者负极表面进行憎水处理，随着ptfe乳液用量或者浓度的升高，荷电保持率在增大。
Long - term stress relaxation experiments of cellular silicone material were carried . the relationship between stress retention and time was obtained , changes aroused from stress relaxation were analyzed by modern analysis technique 摘要对硅泡沫材料的长期应力松弛进行了实验研究，得出了硅泡沫材料应力保持率与松弛时间的关系，并用现代分析测试技术对硅泡沫材料由应力松弛引起的变化进行了分析。
The retention rate among those who complain to customer relations has more than doubled , while its return on investment ( the value of business saved plus increased loyalty and new business from referrals relative to the department ' s total costs ) has risen 200 % 其因客户关系遭投诉的保持率超过同行的两倍有多，而其投资(必要的生意投资加上增加信任度的投资，以及妥善处理投诉而带来的部门总体花费)的回报也上浮了200 % 。
The character of the key accounts could be concluded as : to gain profit long term , have loyalty to the enterprise , play an important role strategically . on the basis of the analysis upwards , the goal of the kam of the hd copper company could be said that to gain the key account loyalty , to increase the rate that keep the key account in the company and to improve the benefit level . to achieve this goal , part 3 points out that the company should understand the change of the relationship , from the key account value factors ( price , quality , creation , reaction speed , etc ) , create and improve the key account value 承接第一部分，本文第二部分深入分析了hd铜业公司大客户管理的理论依据，首先，从企业增长与大客户导向经营理念的关系、大客户容量瓶颈和大客户流失的负面累加效应阐述了hd铜业公司从战略高度思考大客户管理的重大战略意义；其次，深入分析了企业大客户的特征：长期赢利能力强、对企业忠诚、具有重大战略意义，并探讨了大客户细分和选择的方法，在此基础上，进一步分析了hd铜业公司的大客户管理是对大客户关系这项资产的有效管理，进而提出了hd铜业公司大客户管理的目标是驱动大客户忠诚，改善大客户保持率并提高利润水平。
Then based on these theories , the paper puts forward the improved means to define the main parameters in clv model , that is , customer value parameter , dynamic customer retention rate and customer lifecycle time factor . and then an expanded clv model is presented . afterwards , several instances correlated with parameters of clv model are showed 然后在此理论基础上对现有的客户生命周期价值定量计算方法进行完善和改进，从客户利润参数、动态客户保持率和客户生命周期时间因子三个主要方面进行研究，并提出扩展后更完整的客户生命周期价值模型，使其更具可操作性。
Furthermore , with analysing dynamically the guideline values , this paper gathers up the integral evaluation guideline such as characteristic point retain ratio , cluster quantity retain ratio , cluster outline retain ratio and point object deletion ratio etc , these guidelines are used to further quality assessment 对实例中得出的指标值进一步进行动态综合分析，概括出特徵点保持率、聚类数量保持率、聚类轮廓保持率、点目标删除率等综合评价指标，用于进一步的质量评估。
