调节对象参数和运动特性随工况变化的分析

水轮机调节对象的许多参数都是随运行工况变化的。以调节对象线性化模型为基础，从1个实例计算人手，计算了不同工况下水轮机传递系数和发电机6个参数的变化情况，进而计算这些参数变化对捌节对象特征根的影响。通过汁算表明，其水力振荡衰减速度与出力有关．而系统的其他运动特性随工况变化较小。

应用铟源的反应蒸发制备In2O3透明导电膜

本工作说明，在低压氧气氛中。应用铟源的反应蒸发很容易淀积高质量的Ｉｎ２Ｏ３透明导电膜．旦然没有使用锡杂质，但所得膜的性能可以和最好的掺锡的Ｉｎ２Ｏ３膜相比．膜电阻率达２～３×１０￣４Ω·ｃｍ，可见光透过率超过９０％，并且膜生长速率高达２１９／ｍｉｎ．文章对成膜过程作了分析，报道了膜的最佳淀积条件，对由于偏离最佳淀积参数而导致的异常膜的形成机制也进行了讨论．

CAL delivery selection criteria and authoring systems

Abstract  In the past, authoring systems have been used to generate computer-assisted learning materials that have often followed the rather restrictive programmed learning format. A number of innovative ways of using recently developed systems to develop CAL packages that include a wider range of learning activities (access to data bases, simulations, interactive video, etc.) are described. Analogous to the concept of a media selection model, a computer delivery mode selection model is presented as an aid to decision making for designers. This increase in flexibility should broaden the applicability of computerassisted learning (CAL) to a wider range of educational objectives and raise the level of the cognitive emphasis in learning packages, as well as facilitate the implementation of visually appealing materials. The paper also implies a standard of acceptability for authoring systems.     

Enhanced Oil Recovery: The Synthesis of Anthraquinone [1, 2-C] Alkylisoxazole

Anthraquinone [1, 2-C] methylisoxazole is synthesized from 2-ethylanthraquinone through nitration and treating with oleum. The different methods of 2-ethylanthraquinone nitrated were discussed. The optimum conditions were determined. The structure of the product was confirmed by MS and ¹H NMR.
