两个动能耦合Morse振子系统的分岔现象

从两个未耦合的Morse振子出发,首先研究了两个动能耦合的Morse振子系统局域模区域内的分岔结构.发现对弱耦合参数δ,相空间中局域模谐振nm共存与系统能量ε通过不等式 √1/1-ε≥n/m≥√1- ε相关联.同时报导了对称伸缩本征模的分岔现象与能量及耦合常数的关系.在弱耦合参数δ下,在非常低的能量区域内,对称伸缩经历一个pitch-fork分岔.随后,局域模随能量的增加逐渐形成.对中等高能量ε,对称伸缩本征征模在耦合参数范围[-1,0]内由不稳定到稳定到不稳定等交替变化.     

学年学分制模式下的高校学生工作探索

我国目前大多数高校采用学年学分制,与学年制和完全学分制不同,它以学分为计量单位,按学年或学期作为结算时段确定学生的降级和退学标准,有相对固定的修业年限。文章对该模式下的学生工作进行初步探讨,提出了进一步完善辅导员制度、加强班集体建设等系列措施。     

Perceptual learning of dot pattern

Dot pattern is a type of pattern defined by specific spatial relationship among some dots. As a compensation for concrete and meaningful visual stimuli, meaningless dot pattern can be used as stimuli in learning tasks. We performed an experiment for exploring the perceptual learning process of dot pattern against random-dot background. Participants were required to learn two types of dot patterns (9-dot and 11-dot). They were assigned to two groups: participants in Group 1 learned 9-dot pattern first and 11-dot pattern later, while those in Group 2 learned 11-dot pattern first and 9-dot pattern later. The results showed that participants could acquire the spatial relationship of dot pattern through perceptual learning in relatively short learning time. In comparison with 9-dot pattern, learning time of 11-dot pattern was slightly longer and its accuracy rate lower, but there was significant positive transfer effect from 11-dot pattern learning to 9-dot learning.     

二维正态分布矩形区域概率质量的局部单调性

研究了二维正态分布矩形区域概率质量当矩形区域中心沿某特定方向平移时的局部单调性。同时给出了一簇矩形区域,其中任一矩形区域的概率质量对正态分布相关系数的绝对值具有局部单调性。     

计算机辅助设计与分析多模圆锥喇叭天线

多模圆锥喇叭天线是一种应用较广的新型高效率喇叭天线,合理设计的多模圆锥喇叭天线,它的方向图可以得到很好的等化性能,所以被广泛应用于反射镜初级馈源和实验室标准天线等。但是,设计的多模圆锥喇叭波束宽度(-3dB)较窄,喇叭口径在5个波长左右。本文在传统设计方法的基础上,对多模圆锥喇叭天线采用计算机辅助设计,避免了人工计算带来的误差,而且设计范围更加灵活。文章较详细地介绍了设计方法和计算框图,最后给出了分析实例,并具体设计了一种较宽波束的多模圆锥喇叭天线,理论计算和实测结果非常一致,证明了这种方法是行之有效的。

The Experimental and Theoretical Research of “Local Resonance“ in Ultrasonic Honing System

In 1982, Professor Fang Guoliang found the “Non full resonance“ phenomenon in a tool system while he use the thin-long tool ultrasonically machining deep-small hole. He called it as “local resonance“. Also this “Non full resonance“ phenomenon was discovered in the ultrasonic drilling and the ultrasonic honing system later. To its mechanism, professor Fang thought that the coupling of long-thin tool bar and driving system is weak, so the tool bar can vibrate independently, but the quantitative relation betwe...

论铁凝对女性模仿性生存的女性叙事

铁凝一直自我定位于“第三性”写作,可是读罢她的大多数小说之后,却发现了她不同的小说中存在着一个共同的女性生存模式——模仿。这种模仿与生存处境的弱势有关,模仿中的焦虑与性别弱势有关。铁凝的“第三性”声明是作家刻意的性别遮蔽。
