Mechanoluminescent pulse pressure sensors. Processing of output optical signal

The process of mechanoluminescence transformation of a pulse pressure sensor is considered. The process consists in excitation of emission under the action of mechanical loading. An algorithm for use in processing the output optical signal of the sensor that makes it possible to determine an input shock pulse is presented. __________ Translated from Izmeritel’naya Tekhnika, No. 10, pp. 28–31, October, 2007.

A unified proposal for characteristic testing methods and figure of merit of 8‐kV/3.5‐kVA class light‐triggered thyristors

Power devices with high capability have been developed. 8‐kV/3.5‐kA‐class light‐triggered thyristors have the highest capability among power devices. These devices are used in the Kii Channel HVDC transmission system in Japan. In this paper, we report the extracted problems of conventional testing methods of 8‐kV/3.5‐kA‐class light‐triggered thyristors among manufacturers, and the proposed unified testing methods on the basis of element characteristics and operating conditions in the Kii Channel HVDC system. Furthermore, we propose a figure of merit for power devices for the practical use, and try to extract elements used at the Kii Channel HVDC system with small margins and low withstand capabilities. © 2002 Wiley Periodicals, Inc.

MGD工艺技术的特点

应炼油厂要求，FCC既要多产柴油，又需多产液化气，石油化工科学研究院开发了MGD工艺。该工工艺遵循催化裂化的反应机理，把分段进料和汽油回炼紧密组合为一个体系，较好地达到了用掺渣油原料多产柴油和液化气的目的，其汽油烯烃和硫含量降低。从而使炼油厂调合汽油达到产品规格。工艺实施容易，改造投入少、见效快，受到炼油厂欢迎，并迅速推广应用。浅释了MGD工艺的反应机理，并提出了应用中应该注意的问题。     

加氢润滑油基础油光安定性研究进展

加氢处理基础油与溶剂精制基础油相比具有硫、氮含量低，颜色浅，粘度指数高，挥发性低，饱和烃含量高，对添加剂的感受性好等优点。但是，加氢处理润滑油基础油的一个明显缺点就是其光安定性差，即在有氧条件下通过光照（有时也需加热），油品颜色加深、透明度变差，继而有絮凝物或沉淀生成。文章综述了国内外有关加氢润滑油基础油光安定性的原因和解决办法的研究进展情况。

动态光散射法研究海藻酸钠凝胶松弛行为

在前文的基础上，用相关函数轮廓分析的方法剖析了运动模型模式的复杂性。通过海藻酸钠水溶液在０．１ｍｏｌ／ＬＣａＣｌ２水溶液透析凝胶化过程中交联网络的松弛时间谱表明它不是单一的峰，有两上特征运动模式，并随透析向更慢的运动模式发展，这很慢的运动模式估计与区域的结构的生成有关。
