数控机床加工精度异常故障的诊断与处理

社会的迅速发展推动了现代制造技术的进步,也实现了数控机床的推广。由于其是根据加工程序自动加工零件,因此具有加工精度高、生产效率高、加工功能强等特点。然而在实际应用中,因操作人员对影响数控加工精度的因素不甚了解,在加工中,无法进行高精度施工,影响整个工程的质量。为了保证施工质量,文章根据笔者自身多年的工作经验,结合理论分析,对数控机床加工精度异常的故障,找出有效的的诊断措施及相关的应对措施,望能起到抛砖引玉的效果。

The customer consequences of returns in online retailing: An empirical analysis

Pressure continues to build on the operations management function to facilitate system and firm level benefits. In the online marketplace, one area of growing interest is that of product returns. Though commonly viewed as a cost center from an operations perspective, operations’ actions have the potential to strongly influence future customer buying behavior in several ways. Using an archival database of actual purchase and returns history provided by a moderately sized online retailer, this study examines the relationship between a customer's experience of product returns, and subsequent shopping behavior. Employing transaction cost, consumer risk, and procedural justice theories, we demonstrate that the returns management process, rather than being regarded as an afterthought to the production and deployment of goods, can significantly and positively influence repurchase behavior. Additionally, we provide evidence that certain customers should be considered for prioritization in the returns process. We suggest ways through which operations managers can take care in discharging their responsibilities in this area – to make returns processing more than simply a “necessary cost of doing business” rather, using it to their advantage in engendering repeat and increased purchase behavior.     

一起110kV电缆中间接头故障分析

通过对发生故障的110 kV电缆中间接头进行解剖,分析推断故障原因可能是绝缘层与半导电屏蔽层间存在微小气隙缺陷,经长期运行发生局部放电并发展成贯穿性导电通道造成绝缘击穿,提出采取在线局部放电测试的方法对设备健康状态进行监控,及时发现缺陷并予以消缺,防止故障发生.

It focuses on a nationwide case study in Israel, which experienced a massive growth in the extent of company cars and which has implemented various policy changes in the taxation of company cars.

Changes in the taxation of a company car as well as in employer's policy toward company car usage may bring about a significant change in drivers' decisions regarding the willingness to have a company car and their travel behavior.     

技术创新对中国就业影响的实证研究

技术创新对就业来说有利有弊。文章阐述了技术创新对就业的破坏机制和创造机制,通过实证研究发现,30多年的技术创新对我国就业总量的综合影响为负。这主要是因为我国劳动力素质与高技术的不匹配以及劳动力流动性差而造成的结构性失业严重,且由于我国产品创新不足、工资刚性、劳动资本市场不完善等原因,使得技术创新的就业补偿机制发挥不充分。文章在此基础上提出了可行建议。     

农民收入与文化消费牵扯:江苏364个样本

利用江苏364份农民文化消费微观调查数据,实证分析农民收入对文化消费支出的影响。研究结果表明:农民消费类文化活动和免费文化活动并举,共同构成农民文化生活的重要组成部分。农民收入水平是影响农民文化消费的重要因素,家庭人均收入和农民对家庭收入自我评价对农民文化消费有显著正影响,农业收入比重对农民文化消费有显著负影响;收入变量对高收入组农民文化消费影响程度要明显高于中收入组,对低收入组农民文化消费没有显著影响,说明农民文化消费具有一定的收入门槛。
