成人自导学习与支持系统研究
To arouse teachers and students concern for self-directed learning (SDL), so as to help students make better preparation for future development, this article briefly introduced SDL and the needed competencies, and discussed the relationship between problem-based learning( PBL) and SDL, the understanding of SDL of teachers and students, and the expected role of teachers in SDL.
为了促进学习者有效适应未来发展的需要,帮助教师对自导学习(SDL)予以更多思考和关注,文章简要介绍了SDL的含义与所需的能力;重点讨论了PBL模式对SDL的支持关系,师生对SDL的认识,以及教师应在学生SDL中发挥的作用。
Low frequency passive homing is an effective measure of improving torpedo acceptance range.
低频被动自导是鱼雷提高作用距离的有效手段,但被动自导的抗干扰能力差是制约其应用的主要瓶颈,目前主要的被动特征提取方法集中在功率谱特征的提取,但随着对抗器材的发展,功率谱特征很容易被模拟。
To solve the problem that passive homing of lightweight torpedo can not pursue target in sea trial,the fault in sea trial and the torpedo performance were analyzed and compared.
针对轻型鱼雷实航试验中被动自导难以跟踪到目标,其功能未得到充分考核的问题,通过对实航中故障现象和性能参数进行分析比较,找出了问题产生的原因,即试验中的电干扰导致被动自导难以跟踪目标,幅度门非正常开启造成被动跟踪过程中丢失目标。
Traditional guidance law of underwater autoguide weapon had lots of defects,which was unsuitable for the tactical requirement of modern torpedoes.
水下声自导武器的传统导引方式存在着种种缺点,已经不适合现代鱼雷的战术要求。

In order to countermeasure submarine appearing in a close distance, the paper put forward the concept of method for current-location shooting homing torpedo against the uniform acceleration submarine, then gave the simulation model.
针对如何有效打击近距离突然出现的匀速直航潜艇,提出了自导鱼雷对匀速直航潜艇射击的现在位置射击法,即直接按潜艇方位进行射击,建立了鱼雷与潜艇的现在位置射击法对抗模型,并通过实例计算分析了射击距离的确定方法,验证了现在位置射击法对近距离上突然出现的匀速直航潜艇对抗的有效性。
In order to develop the power of torpedo weapon and guarantee the safety of our troops,shooting forbidden zone of homing torpedo was studied.
为充分发挥鱼雷武器的威力,保证编队内我方兵力的安全,研究了自导鱼雷的射击禁区,介绍了鱼雷射击禁区的定义及影响射击禁区的主要因素,分析了射击禁区的划分原理。
