关于两个整数乘法几何简便算法的研究

如图1,将某一整数的个位、十位用较大空白间隔开来,而且个位、十位等依次按照由下到上的次序依次排列．如图2,将另一整数的个位、十位用同样间隔隔开,个位、十位依次按照由左至右的次序排列．由图1、2重叠后,就构成了如图3的矩阵图形．注：在读解图3这样的基本图形时,按照由左至右,由下到上的次序读解．由于A＊B等于B＊A,所以按照先由下到上,再由左到右的次序也可．     

新闻评论者思想力刍议

新闻评论作为“报刊的“眼睛”和“报刊自己的“喉舌”,其作用的发挥有赖于新闻评论者“思想的力量”,具体包括思维力、选择力和判断力。新闻评论者通过自己的选择、阐释、判断,增加了新闻事实的认知价值,提供了一种有附加值的新判断。     

生活的次序

人们用来了解别人的时间太多,用来了解自己的时间太少.在资讯泛滥、八卦鼎沸的今天,这一先天的隐疾被充分激活,恶性膨胀.在终日埋头于电脑、出入于网络的生活中,我们给自己留下的空间有多少?大到人生的走向,小到衣食住行的选择,有多少是随波逐流的跟风,又有多少是自知之明的判断?

觅蛛丝马迹 猜生词含义——例谈阅读理解词义题的解题技法

正几乎所有词义题的解题突破口都集中在"上下文语境"及"构词法"这两个方面。同学们要学会抓住文中所留下的任何蛛丝马迹,巧妙猜测生词含义。巧抓语境猜词义一、根据上下文的同义词或近义词关系猜测词义。作者为了更清楚地解释某一事物或现象,经常在生词前后用其他词对其进行解释或强调。常见的引出同义词的标志性词语有:or,like,such as等。如:例1(2014年广东卷,保留原题号)...In the Far East in ancient times,the umbrella     

Fuzzy-based risk prioritization for a hydrogen refueling facility in Malaysia

Hydrogen is starting to be mentioned as an alternative fuel to replace the fossil fuel in future transportation applica- tions due to its characteristics of zero greenhouse gas emission and high energy efficiency. Before hydrogen fuel and its facilities can be introduced to the public, relevant safety issues and its hazards must be assessed in order to avoid any chance of injury or loss. While a traditional risk assessment has difficulty in prioritizing the risk of failure modes, this paper proposes a new fuzzy-based risk evaluation technique which uses fuzzy value to prioritize the risk of various scenarios. In this study, the final risk of each failure modes was prioritized by using the MATLAB fuzzy logic tool box with a combination of two assessments. The first assessment was concerned with the criteria which affected the actual probability of occurrence. This assessment considered the availability of the standard that was applied to prevent the likelihood of the scenario occurring. On the other hand, the second assessment was focused on evaluating the consequence of the failure by taking into account the availability of detection and the complexity of the failure rather than only the severity of the scenarios. A total of 87 failure scenarios were identified using failure modes and effect analysis （FMEA） procedures on hydrogen refueling station models. Fuzzy-based assessments were performed through risk prioritizing various failure scenarios with a fuzzy value （0 to 1） and risk level （low, medium, and high） while a tra- ditional risk assessment approach presented the risks only in forms of level （low, medium, and/or high）. Availability of the fuzzy value enabled further prioritizing on the risk results that fell in the same level of risk. This study concluded that fuzzy-based risk evaluation is able to further prioritize the decisions when compared with a traditional risk assessment method.     

小议手风琴三抖技巧练习要点

手风琴三抖技巧在手风琴技巧当中属于比较富有表现力的技巧,但是在实际教学过程当中,很多的学员甚至部分老师对如何正确掌握这一技巧还是一知半解,本文在此提出一些建议,供各位老师学员参考。     

“这个例句不是连动句”吗

“东郭先生牵着毛驴在路上走。”这个句子是不是连动句?何联合教师认定它不是连动句(《这个例句不是连动句》,载于2000年第1期《小学教学研究》),其理由主要是：“有动作,至少两个;动作有次序,动作连着动,动作连得紧;动作是同一个对象所发出”,这是连动句的特点,而“东郭先生牵着毛驴在路上走”中的两个动作是同时进行的。“牵着毛驴’只是表示东郭先生‘在路上走’的方式”。并非“连着动”,“不存在连动关系”。

拼音教学中对学生后天分化差异资源的利用

近年来,从事一年级拼音教学的语文老师发现,由于种种因素,学生在拼音的掌握方面水平参差不齐,一些学生在学前的过度训练,造成了他们在语文学习起跑线上的差异日益明显。拼音学习与其他知识点学习的不同点在于,它在知识发生、发展的逻辑次序上表现出来的起点是隐性的,而学生已有的知识经验即现实起点却是显性的。学生拼音基础的种种差异,对一年级学
