基于可配置规则的BOM视图转换方法

在确保物料清单(bill of material,BOM)多视图之间产品数据一致性和完整性的前提下,为实现BOM视图转换技术能够满足企业业务规则的个性化需求并适应企业业务规则可能发生的改变,提出了基于可配置规则的BOM视图转换方法.在分析企业中各种BOM视图之间关系的基础上,建立了BOM视图及其转换过程的基础模型,给出了装配转换规则的结构定义及其配置方法,通过实际案例介绍了该方法在BOM视图转换过程中的应用,表明了该方法能够满足企业业务规则的个性化需求并适应企业业务规则的变化.     

Impact of personality and intelligence on job satisfaction of assembly line and bench work - an industrial study

A study of the impact of machine-paced (M/P) and self-paced (S/P) work on job satisfaction of 28 female industrial assembly workers was evaluated in which M/P work was confounded with simplified work and the S/P job was confounded with enriched tasks. Results indicated the following:

1. 1. Over three-quarters of workers were more satisfied in S/P jobs, while only less than one-quarter were more satisfied in M/P jobs.

2. 2. The 16PF personality test effectively predicts (0·88 multiple correlation) the satisfaction ratios of M/P to S/P jobs.

纳米In2O3／TiO2介孔复合体的制备及其光致发光性能研究

本论文利用尿素水解均匀沉淀法制备锐钛矿型纳米TiO2介孔粉体，然后在硫酸铟溶液中浸泡一周，并在650℃下退火处理5h，制得纳米In2O3／TiO2介孔复合体。采用X射线衍射（XRD）和光致发光（PL）谱表征In2O3／TiO2介孔复合体的组成结构和发光性能，并对相同温度退火处理下的介孔TiO2粉体进行比较，结果表明：经过650℃退火后，在激发波长380nm，发射波长570nm附近，纳米In2O3／TiO2介孔复合体产生荧光增强效应。     

Templated Self‐Assembly of Block Copolymers: Top‐Down Helps Bottom‐Up

One of the key challenges in nanotechnology is to control a self‐assembling system to create a specific structure. Self‐organizing block copolymers offer a rich variety of periodic nanoscale patterns, and researchers have succeeded in finding conditions that lead to very long range order of the domains. However, the array of microdomains typically still contains some uncontrolled defects and lacks global registration and orientation. Recent efforts in templated self‐assembly of block copolymers have demonstrated a promising route to control bottom‐up self‐organization processes through top‐down lithographic templates. The orientation and placement of block‐copolymer domains can be directed by topographically or chemically patterned templates. This templated self‐assembly method provides a path towards the rational design of hierarchical device structures with periodic features that cover several length scales.
