纯循环连分数的收敛性是一个很复杂的问题,实二次无理数的无限简单连分数一定可以表为一个循环连分数,循环连分数一定收敛于一个实二次无理数.但对于一般的循环连分数,无法计算出这个收敛值.这里介绍一种使用特征方程的方法,来计算一类特殊的纯循环连分数的收敛值,针对这类特殊的纯循环连分数的收敛性做了一个定量的结论. 相似文献

从简单连分数[a0，a1，a2，L]出发，把连分数中的分子从1推广到正整数，从而得到另一种形式的简单连分数，继而讨论其渐近分数的有关性质及连分数与实数的互化关系，推广后的连分数在某些方面的讨论比原来的连分数要简洁些。最后应用它来解某些二元一次不定方程和计算平方根的近似值。 相似文献

要求这两个连分数之和，显然不可以用通分的方法，也不能将每一个连分数化为单一的分数(非连分数)，因此必须另寻解题的突破口．仔细观察题目，我们发现这两个连分数中有相同的“元素”： 相似文献

从主客体关系来看，现象是认识活动的直接对象物，是主客体相互作用的直接产物。 现象的生成条件是：第一，客观条件。包括物自体（客观事物）、时间、空间和环境等。第二，主体条件。 指主体的感官功能、心理、情绪、意志、知识和理性等。第三，观察仪器对于现象的生成具有重要意义。 相似文献

Information is presented about the organization of graduate studies, based on questionnaire responses of 582 coordinators of Canadian graduate programs. These coordinators, who were representative of disciplines and geographic regions, provided information about a wide range of matters, including enrolments, staff, admissions, supervision, research, publications, financial support, teaching experience, and completion rates and times. Many substantial differences were noted among the percentage frequencies of responses for departments classified by discipline and size. For example, students were perceived to choose their doctoral theses topics themselves much more frequently in education, social sciences, and humanities than in engineering, medical sciences, physical sciences, and biological sciences. Also, departments with smaller numbers of full-time graduate students tended to provide all doctoral students, with some teaching experience to a greater extent than did larger departments. 相似文献

This essay attempts to counter the dreariness of postmodern critique and culture by locating the vital force of phantasy, rhetoric, argument, hope, and memory in contemporary public affairs. More particularly, it engages recent controversies about collective memory and the FDR memorial statue especially to generate a greater sensitivity to the fact that we are agents (and not just dupes) of history. The body, symbolic and material, is a core site for the history, theory, and practice of democracy, I argue, and is the hard kernel of collective identification and division. Methodologically, the essay fuses Aristotle and Lacan's ideas about phantasy as a perceptual device, which gages and creates public and personal desire, as an analytic frame for the study of public discourse. 相似文献

实践的自由与美的范畴 总被引：10，自引：0，他引：10
张玉能 《华中师范大学学报(人文社会科学版)》2003,42(1):47-53
人，作为个体的生存，从实践（以物质生产为中心）出发才逐步生成，而在实足走向创造的过程中，人们才不断达到一定的自由境界。正是人的实践－创造的自由使自然人化，人也人化，从而产生出人对现实的审美关系；这种审美关系体现对象之上就是美，而体现在人本身之上则是美感。人类的实践－创造的自由同样是一个历时性的过程和一个共时性的结构，因此，它不仅有不同的自由程度和不同的自由境界，而且还有自由，反自由，不自由，准自由等几个维度；与这些不同的自由给度相关便形成了美，丑，柔美，刚美，悲剧性，喜剧性，滑稽，幽默的相应的美的范畴，并形成各个美的范畴之间的过渡，转化，对应等关系，从而形成一个完整的美的范畴体系。 相似文献

在日语中,一个句子中同时出现两个以上“”或者“”的情况是屡见不鲜的。当一个句子里同时有两个“”时,只能有一个提示主题(大主语),另一个只能表示对比,起强调作用。当强调的内容是状态、存在、动作等的主体(小主语)时,小主语用“”,强调的内容是谓语部分时,小主语用“”。当一个句子中同时有两个“”时,大主语的“”表示排他,是句子叙述的重点,强调在一定范围中,被判断状态、存在、动作的主体只有“”或者在一定范围中的最甚者;小主语的“”只单纯表示被判断状态、存在、动作的主体。 相似文献
