汽车LIN总线数据监视器的设计与实现

LIN（Local Interconnect Network）总线是一种在汽车电子控制系统中已被普遍采用的低速、低成本的串行通讯网络。为了对基于LIN总线的分布式电子系统进行LIN总线信号测试和数据分析,对ELM633芯片的硬件电路进行设计,运用VC＋＋软件编制实用软件,开发了操作简便的汽车LIN总线数据监视设备,由此可以成功实现对车辆LIN总线上全部信号的捕捉和采集。它的使用对LIN总线信号测试、数据分析和相关教学培训等工作具有一定的应用价值。     

“不以其道得之”再探

《论语·里仁》:"贫与贱,是人之所恶也;不以其道得之,不去也。"历来多有歧解。解决这个问题的关键在于对"得"的理解。若将"得"理解为"有得、得利",则非常通畅。而"得之"的"之",是代词,位于动词"得"的后面,意义已经虚化,主要起强调动词的作用。此句义指:贫与贱,是人人都不希望得到的,但如果不按正道而得利,君子将不去除贫贱(即安于贫贱)。孔子的言行,恰好证明了他的这句话。     

Basic Mandarin color terms

In comparative studies of basic color terms of various ethnic groups, Berlin and Kay found that the number of basic color terms used is greater, the more highly developed a culture becomes and vice-versa (Berlin and Kay 1969: 16). According to their thesis, peoples possessing the most highly developed cultures use 11 basic color terms, or the equivalents of white, black, red, yellow, green, blue, brown, orange, purple, pink, and gray. These 11 color terms are found in Japanese, Korean, and Cantonese. However, as only six are found in Mandarin, Mandarin was assigned to a lower stage of cultural development. This is incorrect. In an effort to prove this assertion, this author has conducted numerous studies. Based on research of Mandarin color terms and mapping response, this study attempts to prove that Mandarin has long contained the 11 basic color terms noted by Berlin and Kay. However, after conducting a mapping response study, it was discovered that the Berlin-Kay color set (i.e., the Berlin-Kay-MacLaury Munsell set) is inadequate for examining low saturation basic color terms such as he (Br) and cang (grayish BG), the representative colors of which are difficult to fully ascertain. During this study, this author discovered a certain degree of difficulty hindering mutual understanding between Eastern and Western cultures. Consequently, this study seeks to promote a degree of such understanding. © 1997 John Wiley & Sons, Inc. Col Res Appl, 22, 4–10, 1997.

《步天歌》星象——中国传承星象的晚期定型

:《步天歌》属初唐作品 ,主要记载两汉时期以后的星象。由于其主要靠抄本流传 ,且行文过简 ,枝节缺失较多 ,讹误差错不少。但《步天歌》是对隋唐之际传统的三家星官混一的歌诀式总结 ,流传甚广。朝鲜、日本、越南及邻近我国东南沿海国家都有其流传。因此 ,《步天歌》无疑是一部具有较大影响的古代天文星象诗歌著作
