通过"中国知网"检索2011年发表的主题为"土壤深度"的论文,选择其中90篇查阅并下载图的标目为"土壤深度"及其含义的41篇论文进行图形式样调查统计,以探讨此类图形的正确、规范表达模式。结果显示:有34篇用曲线图,且曲线图出现7种不同的表达形式。对各曲线图式样以及图中标目的量与单位表达的谬误辨析结果表明,有关土壤特征指标曲线图的准确、规范表达模式为:以"土壤深度"为横标目(自变量),土壤特征指标为纵标目(因变量)且纵坐标轴向上,标值均为正数,标值增量方向与坐标轴方向一致,标值线向内。 相似文献

周继荣同志《书稿编辑过程中量与单位方面应注意的几个问题》(下文简称《问题》)一文中列举了科技书刊中存在的一些量和单位方面的问题 ,而作者在举例中又存在两个错误 :1 插图不规范科技期刊中规范的函数曲线图应该是 :若坐标轴表述的是定性的变量 ,即未给出标值线和标值 ,则在坐标轴的尾部应按变量增大的方向画出箭头 ,并标注变量 ;若坐标轴上已给出标值线和标值 ,即坐标轴上变量增大的方向已经示明 ,则不应该再画箭头。标目应与被标注的坐标平行 ,居中排印在坐标轴与标值的外侧。既然作为范例就应该是标准规范的图 ,而《问题》的作者所… 相似文献

科技论文的统计检验式审读 总被引：1，自引：0，他引：1
统计学方法是进行科学研究及撰写科技论文所必需的重要手段之一。它运用概率论和数理统计的原理、方法,对所收集的材料进行分析,选择正确的统计指标,并对统计指标作出正确的解释。由于科学研究的对象通常变异较大,各种影响因素又错综复杂,故需运用统计方法透过偶然现象来推测其规律性。作为一名科技编辑,对科技论文除了“能编”之外,还应“会审”。运用统计学知识对科技论文进行审 相似文献

坐标轴上标值线的形式未见有规定,在实际应用中,它有长、中、短3种形式,它们在坐标图中各自扮演着不同的角色,发挥着不同的功能与作用.对于重要的、起到以点带面启示作用的标值处要用长标值线,余均用短标值线;中标值线的功能与作用介于长、短标值线之间,标值线侧旁有时要带有标值,有时又无须带有标值.长、中、短3种标值线在坐标轴上的分布,务必均衡、对称和有规律性. 相似文献

In its original presentation, scores on two of the three subscales of the Classroom Citizenship Behavior scale were highly reliable. Scores on the subscale measuring the third dimension of classroom citizenship behavior, Courtesy, had poor reliability. We inductively derived additional items for the Courtesy subscale and tested structure and reliability of the revised scale. Exploratory factor analysis indicated that the scale readily divided into three factors of six items each, consistent with the proposed model. Furthermore, the subscale scores associated with these factors demonstrated high reliability. Next, two additional communication classes completed the revised scale and confirmatory factor analyses were run on the new version of the three-factor scale. Fit indices were good. The revised Classroom Citizenship Behaviors scale provides a stronger tool for investigating student behaviors that contribute to the effective functioning of the classroom environment. 相似文献

An experiment was conducted with 150 male college undergraduates playing different video games to investigate the impact of violent content, frustration with gameplay, and the interaction of those factors with aggressive personality (trait hostility). Results indicate that both violent content and frustration individually leads to greater scores on a state hostility scale, and the interaction of violent content and frustration leads to the highest scores on that scale. Results are discussed in terms of the Frustration-Aggression hypothesis and the General Aggression Model. 相似文献

This paper deals with automating the drawing of subway maps. There are two features of schematic
subway maps that make them different from drawings of other networks such as flow charts or organigrams.
First, most schematic subway maps use not only horizontal and vertical lines, but also diagonals. This
gives more flexibility in the layout process, but it also makes the problem provably hard. Second, a subway
map represents a network whose components have geographic locations that are roughly known to the users
of such a map. This knowledge must be respected during the search for a clear layout of the network.
For the sake of visual clarity the underlying geography may be distorted, but it must not be given up, otherwise
map users will be hopelessly confused.
In this paper we first give a rather generally accepted list of rules that should be adhered
to by a good subway map. Next we survey three recent methods for drawing subway maps, analyze their
performance with respect to the above rules, and compare the resulting maps among each other and to official
subway maps drawn by graphic designers. We then focus on one of the methods, which is based on mixed-integer
linear programming, a widely-used global optimization technique. This method guarantees to find a drawing
that fulfills a subset of the above-mentioned rules (if such a drawing exists) and optimizes a weighted
sum of costs that correspond to the remaining rules. The method can draw even large subway networks such
as the London Underground in an aesthetically pleasing manner, similar to maps made by professional graphic
designers. If station labels are included in the optimization process, so far only medium-size networks
can be drawn. Finally we give evidence why drawing good subway maps is difficult (even without labels). 相似文献

Regarding evaluation of individual researchers, the bibliometric indicators approach has been increasingly discussed recently, but there are some problems involved with it: construct definition, measurement errors, level of scale, dimensionality, normalization. Based on a psychometric model, the Rasch model, we developed a measuring scale for the theoretical construct ‘researcher’s performance capacity,’ defined as the competency of a researcher to write influential papers. The aim was a scale that is one-dimensional and continuous, is applicable to bibliometric count variables, and takes measurement errors into account. In this paper we present the psychometric model (Bayesian Poisson Rasch model, BPR) and its assumptions and examine the behavior of the model under various sampling conditions. For a sample of N?=?254 researchers in a quantitative methodology section of an undisclosed German academic society for social sciences, using the BPR model we developed a scale that we named ‘Bibliometric Quotient’ (BQ, M?=?100, SD?=?15) (following the term ‘intelligence quotient’). The scale fulfills most of the test-theoretical requirements (e.g., high reliability αt?=?.96, no differential item functioning except for academic age and German states) and in addition allows researchers to be ranked. Women’s BQ scores were 8.3 points lower on the scale than men’s BQ scores. 相似文献
