建设信用经济的理性思考

信用经济是市场经济发展到一定阶段的必然趋势和客观要求。在这种经济中，信用不仅仅是作为交换媒介存在，更为重要的是信用作为除市场以外的另一种资源配置方式。它的产生需要一些特定的条件，文章即从个人、企业、政府三方面信用建设入手，提出创建信用经济条件产生的具体措施。

The benefits of being present: Mindfulness and its role in psychological well-being.

Mindfulness is an attribute of consciousness long believed to promote well-being. This research provides a theoretical and empirical examination of the role of mindfulness in psychological well-being. The development and psychometric properties of the dispositional Mindful Attention Awareness Scale (MAAS) are described. Correlational, quasi-experimental, and laboratory studies then show that the MAAS measures a unique quality of consciousness that is related to a variety of well-being constructs, that differentiates mindfulness practitioners from others, and that is associated with enhanced self-awareness. An experience-sampling study shows that both dispositional and state mindfulness predict self-regulated behavior and positive emotional states. Finally, a clinical intervention study with cancer patients demonstrates that increases in mindfulness over time relate to declines in mood disturbance and stress.

Lipase production in continuous culture of Candida rugosa

The yeast Candida rugosa produces multiple extracellular lipases. The production of extra‐ and intracellular lipases was investigated in continuous cultures using a sole or different mixtures of carbon sources. Also, the effect of different C:N ratios was tested. Lipase productivity in continuous cultures increased by 50% compared with data obtained from batch fermentations and depended on the dilution rate applied. Maximum yields relative to consumed substrate were obtained with oleic acid at low dilution rate. It was found that during nitrogen limitation, lipase activity was suppressed. All carbon source mixtures tested allowed both cell growth and lipase production, but extra‐ and intracellular lipase activities were affected by the combination of substrates used. Maximum extracellular lipolytic productivity was attained with lactic and oleic acid mixtures, probably due to the non‐repressor effect of these carbon sources. The chemical composition of the biomass also depended on the type of substrate used and was related to the accumulation of lipidic compounds as intracellular inclusions, which were observed when oleic acid was used as the carbon source. The results obtained were compared with previous data from batch and fed‐batch cultures in order to select the best process strategies for the lipase production with C rugosa. The best lipase yields were obtained in fed‐batch fermentations using oleic acid. Copyright © 2003 Society of Chemical Industry     

时钟信号在传送网中漂移损伤研究

论述了漂移损伤的理论表示、指标规范，测试了时钟信号在PDH传输系统、SDH链路传输系统、SDH环路传输系统中的漂移损伤。从理论和实验结果证明PDH传输系统引入的漂移损伤比SDH传输系统小得多，能够作为时钟信号的传输链路。同时对SDH系统漂移损伤主要由指针调整引起的论述进行验证，发现指针正常情况下几乎不调整，因而由它引起的漂移损伤应很小。
