调Q频率对半导体侧向抽运固体激光器热稳定性的影响

热稳定性是半导体激光泵浦固体激光器（DPSSL）的重要问题，对出光功率、光束质量以及总体稳定性等都有严重影响。研究了热稳定腔的热稳定性条件，采用临界腔的方法实验测量了不同调Q频率激光振荡的热稳定区。结果表明：随着激光调Q频率的提高，激光的热透镜焦距变长，热稳定区变宽。研究结果对热稳定性理论进行了补充，为非线性效应等脉冲激光应用的腔型设计提供了有益指导。

低渗透油藏超短周期间歇注水方式研究

大港油田南区低渗透油藏两相共渗区窄，注水开发短期内含水上升迅速，根据间歇注水理论，并借鉴国内外油田的实验经验，1998年在舍女寺油田女20、女34区块开展超短周期（周期0．5－5d)间歇注水试验。总结不同注水周期和频率及油并不同含水级别对其效果的影响。认为超短周期间歇注水可改善油层动用状况，对中、低含水受益油井之注水井有较好的适用性，为低渗透油藏注水开发提出了一种经济有效的方法。图1参（王学立摘）。     

The hygienic working practices of maintenance personnel and equipment hygiene in the Finnish food industry

The hygienic working practices of the maintenance personnel as well as the hygiene of the equipment in the food industry were investigated with questionnaires and microbial surveys. The protective clothing, washing of hands and tools as well as avoiding foreign bodies left on the production lines should be targeted when the hygienic working practices are developed for maintenance personnel. Based on the questionnaire to food processors, packaging machines, conveyers, dispensers, slicing and cooling machines were considered the most problematic pieces of equipment hygienically mainly because of poor hygienic design. In order to improve food safety, both the training of maintenance personnel in food hygiene and equipment design should be more emphasised.

The Structure of Working Memory From 4 to 15 Years of Age.

The structure of working memory and its development across the childhood years were investigated in children 4-15 years of age. The children were given multiple assessments of each component of the A. D. Baddeley and G. Hitch (1974) working memory model. Broadly similar linear functions characterized performance on all measures as a function of age. From 6 years onward, a model consisting of 3 distinct but correlated factors corresponding to the working memory model provided a good fit to the data. The results indicate that the basic modular structure of working memory is present from 6 years of age and possibly earlier, with each component undergoing sizable expansion in functional capacity throughout the early and middle school years to adolescence.
