交流耦合的硅条探测器有较高的电压跨接在耦合电容上面,坏的耦合电容使约50V 电压加到 SVX 器件,测量了坏的耦合电容对 SVXD(rod soft 3 μm)、SVXH(rad soft 1.2 μm)和 SVX2b(tad soft 1.2 μm)放大器/读出器件的影响.试验结果表明,当一个过载电压直接加到一个 SVX 道时,相邻的一些道发生饱和,这种效应是由于在 SVX 基片内的电流扩散而不是探测器的表面电流形成的。文中讨论了饱和量大小和可能的解决途径。

该研究包含两个调查。主要目的1、了解、描述和分析国际互联网上所出现的有关音乐治疗的信息及其特征;2、指导一个对音乐医疗不熟悉的人在国际互联网上收集和准确地找到关于音乐医疗的有意义的信息。调查1对20个搜索引擎中的201个网站进行了调查。结果显示,美国音乐治疗协会(AmTA)的网站以最高的出现频率排列在所有网站的最前面。教育机构和商业机构的网站也有很高的使用率。大多数排位靠前的网站对音乐医疗下了较传统的定义(与美国音乐医疗协会AmTA一样),这些网站与相关网站的链接也很方便。一年以后再次重复了这一调查过程(调查2)。调查2使用的搜索关键词为“什么是音乐医疗?”结果,145个网站在这次调查中出现。其中,美国音乐医疗协会的网站又一次以最高的使用率排列在所有网站的最前面。教育机构和商业机构的网站虽有很高的使用率,但这些排列靠前的网站中只有一半对音乐医疗下了传统的定义。调查结果显示,用”音乐医疗”作为关键词出现在A m T A网站的可能性比用“什么是音乐医疗”高。这表明,搜索引擎对简单明了的问题更容易识别。也许AmTA可以在这方面作改进。调查还表明,商业网站的“音乐治疗”信息缺乏可靠性,个人在参考时应谨慎。

鳙(花鲢)在自然环境中分布于中国南部流域至阿穆尔河,是重要的经济性鱼类,具江湖生殖洄游特性。大坝建设阻碍了其洄游产卵繁殖通道,导致自然环境中其繁殖力的下降,需要有效的过鱼设施帮助鳙通过大坝等水流屏障。为了设计高效的鱼道引导鳙通过,本文通过自制密封的鱼类游泳实验装置,研究了鳙幼鱼游泳能力。测定了5个温度(5、10、15、20和25℃)下鳙幼鱼的临界游泳速度。通过测定不同温度下,疲劳前后血清总蛋白(TP)、血糖(GLU)和甘油三酯(TG)含量,评价疲劳运动引起的生理胁迫。结果表明,在试验温度范围内,随着温度的升高,临界游泳速度显著提高(Pm/s)。在疲劳运动后,血清总蛋白、血糖和甘油三酯含量显著升高(P<0.05)。水温低于15℃与高于15℃相比,鳙疲劳运动后血清总蛋白、血糖和甘油三酯含量显著升高。以鳙幼鱼为研究对象,研究了非适宜温度环境和疲劳运动胁迫下鱼类的生理反应。以期为鱼类生理学研究和渔业保护管理等领域提供理论依据,为制定有效的鱼道提供数据参考。
