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.     

Women''''s Vocabulary——Different Languages for Different Sexes

Sex differences are a fundamental fact of human life and it is not surprising to find them reflected in language.It's said that women tend to use more standard forms of English,while men tend to use less standard forms of English.Over the past thirty years,and as a result of the women's movement,gender issues have become entangled with issues of language.Recent research indicates that sex may be more fundamental as an influence on sociolinguistic variation than has been recognized so far.This article will try to discuss the different language use between men and women.     

对青海省高等级公路水资源利用技术的思考

青海省自然环境条件恶劣，公路绿化建设难度大，突出表现在降雨量少且集中、蒸发量大、不同地区分布不均等特点，路侧植物存活与生长困难，建设成效不理想．在降雨量小时起不到补充水分的作用，大雨暴雨时雨水白白流走，并对公路边坡稳定构成威胁．在这样的条件制约下．本研究提出在保护沿线生态环境的前提下，将雨水有效地收集起来，用于公路的植被恢复，既保护了水资源，同时也减少了水害对公路的影响．

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。     

农村土地产权制度与土地综合生产能力的经济学分析

现存农村土地制度存在的主要问题是:土地的产权关系不明晰,土地使用权的不稳定,降低了农民对土地的利用效率;农民进行土地改良的投资十分有限,大大降低了土地综合生产能力.本文从产权经济学的角度分析农村土地产权制度与土地综合生产能力的关系.
