测试技术课程改革与实践

测试技术属于边缘科学,起点高、知识面广、难度大,不仅学科跨度大,涉及机、电、液、光、声、数学及自动控制等几方面,而且该课程实践性很强,实践环节在整个教学过程中占有相当大的比重,因而教与学均存在一定的困难。文章在分析传统教学存在问题的基础上,提出新的教学方法,调整教学内容顺序,突出教学重点,运用工程实例教学法,强化学生的实验训练。     

Estimation on Varying-Coefficient Partially Linear Model With Different Smoothing Variables

The authors give the estimation on the varying-coefficient partially linear regression model with different smoothing variables. The efficient estimators of the intercept function and the coefficient functions are obtained by a one-step back-fitting technique based on their initial estimators given by local linear technique and the averaged method. Furthermore, their asymptotic normalities are given. Some simulation studies are used to illustrate the performances of the estimation.

通过对近二十几年"魔幻现实主义文学"国内研究成果的梳理,对研究中的线索和成果进行大致的总结,从而了解研究现状,并取得对"魔幻现实主义"等一系列重要文学概念相对准确的理解.     

茅盾小说与"红楼"情结

“红楼”情结是茅盾经久的“图像仓库”的土壤。但这种情结不是板块式地嵌入的 ,而是经由转化、挪移、重组化合而生成的。这种历史的承传 ,可以是正面的 ,也可以是负面的。同时 ,这种对民族文化的吸取是在与中外艺术的多元交糅的关系中 ,融通建构的。     

Fusion of Intelligence Information: A Bayesian Approach

The attack that occurred on September 11, 2001 was, in the end, the result of a failure to detect and prevent the terrorist operations that hit the United States. The U.S. government thus faces at this time the daunting tasks of first, drastically increasing its ability to obtain and interpret different types of signals of impending terrorist attacks with sufficient lead time and accuracy, and second, improving its ability to react effectively. One of the main challenges is the fusion of information, from different sources (U.S. or foreign), and of different types (electronic signals, human intelligence. etc.). Fusion thus involves two very distinct and separate issues: communications, i.e., ensuring that the different U.S. and foreign intelligence agencies communicate all relevant and accurate information in a timely fashion and, perhaps more difficult, merging the content of signals, some "sharp" and some "fuzzy," some dependent and some independent into useful information. The focus of this article is on the latter issue, and on the use of the results. In this article, I present a classic probabilistic Bayesian model sometimes used in engineering risk analysis, which can be helpful in the fusion of information because it allows computation of the posterior probability of an event given its prior probability (before the signal is observed) and the quality of the signal characterized by the probabilities of false positive and false negative. Experience suggests that the nature of these errors has been sometimes misunderstood; therefore, I discuss the validity of several possible definitions.     

关于"更好地理解"——以施莱尔马赫和伽达默尔为中心

施莱尔马赫提出解释学的任务是与文本的作者一样好甚至比他更好地理解他的话语。为此他主张通过"重构"使解释者与原作者处于同一层次,从而把握作者无意识保留的东西。伽达默尔认为理解总是相互理解。他以解释学的处境、视域的融合阐明了解释者对文本的理解问题,提出与其说更好地理解,不如说不同理解。然而,既然在视域的融合中,解释者的视域起决定性作用,那一切理解也就是当代理解。     

技术路径与中国经济增长

中国在改革开放进程中所采取的积极的产业政策拓展了与发达国家或地区的贸易关系,加快了外资引进的步伐。对外贸易和外资引进产生了技术的"外溢"和"干中学"效应,提高了市场的竞争程度,也促使国内企业积极去改进原有技术和开发新技术。这三个技术进步路径共同推动了企业技术的进步,促进了中国经济的增长。     

谈“声、情、理、心”的高师声乐课教学法

笔者结合自身教学实践,认为高师声乐教学除了要重视歌唱技能技巧训练外,还必须注重"声、情、理、心"的训练,即:重视发声练习,处理好技巧与情感的平衡,加强学生对歌唱原理的认识和把握,培养学生良好歌唱心理等方面的训练。
