Every living thing has a physical boundary that separates it from its ex-ternal environment. Beginning with the bacteria(细菌) and the simple cell and ending with man, every organism has a certain limit which marks where it begins and ends.Anyone who has had experience with dogs, particularly in the country-side such as on farms, is familiar with the way in which the dog handles space. In the first place, the dog knows the limits of his master蒺s “yard”and will defend it against encroachmen…  相似文献

The more unambiguous statement of the P versus NP problem and the judgement of its hardness, are the key ways to find the full proof of the P versus NP problem. There are two sub-problems in the P versus NP problem. The first is the classifications of different mathematical problems (languages), and the second is the distinction between a non-deterministic Turing machine (NTM) and a deterministic Turing machine (DTM). The process of an NTM can be a power set of the corresponding DTM, which proves that the states of an NTM can be a power set of the corresponding DTM. If combining this viewpoint with Cantor’s theorem, it is shown that an NTM is not equipotent to a DTM. This means that "generating the power set P(A) of a set A" is a non-canonical example to support that P is not equal to NP.  相似文献

The Call of the Wild is Jack London’s first bestseller and is one of the most popular novels during the early twentiethcentury in America. It is considered as a model of American literature. This novel depicts how Buck turns from a dog to a leading wolf that returns to the nature. Buck reflects not only the figure of the author but also his aspirations and pursuits. When comparing Buck with the author, it can be said that to a large extent Buck is the author himself-the combination of reality and ideal.  相似文献

The combination of online or semi-online with deterioration jobs has never been researched in scheduling problems. In this paper, two semi-online parallel machine scheduling problems with linear deterioration processing time are considered. In the first problem, it is assumed that the deterioration rates of jobs are known in an interval, that is, bj ∈[0, α], where 0 〈α≤ 1 and bj denotes the linear deterioration rate. In the second problem, it is assumed that the largest deterioration rate of jobs is known in advance, that is, b = max1≤j≤n {bj }. For each of the two problems, a heuristic MBLS algorithm is worked out and its worst-case ratio is analyzed. At the same time, the worst-case ratio of the list (LS) algorithm is investigated and it is proved that all the ratios are tight.  相似文献

"Beauty is truth, truth beauty"-the famous line in English romantic poet John Keats’Ode on a Grecian Urn-has triggered wide discussion and numerous interpretations. From the point of"negative capability", a phrase first coined by Keats himself, this paper is attempting to display the consistency between that poetic line and the poet’s creation and life attitude on the whole. For this purpose, this paper will mainly introduce and interpret five of Keats’famous odes in the order of their display of his"rising acceptance of life": Ode to a Nightingale, Ode on a Grecian Urn, Ode to Autumn, Ode on Melancholy and Ode on Indolence. This paper would like to show in the first three Keats’s positive quest in different aspects and on certain levels, the fourth the underlying tone of life’s polyphonous song, and the final the"negative capability"that constitutes his healthy attitude toward creation and life. Finally, this paper hopes to demonstrate that it is such capability that enables the poet to growingly accept life, and it is also essential to him as a philosophical poet.  相似文献

1. A brief introduction The Bible is the holy books of the Christians: It is the classic works of Christianity. It consists of the Old Testament and the New Testament, each consisting of several volumes written at different times. It first appeared in Hebren because it was originally written by the Jewish people. It's said that Christianity came into being in the middle of the first century A. D. But the Old Testament appeared much earlier than that. We can't say exactly when it was written. We only know that it appeared gradually, bit by bit, in small collections during the last three centuries B. C and the first century A. D. As for the New Testament, it appeared after the death of Christ,in the first two or three centuries A. D. It was said to be spreaded first by the followers of Jesus Christ, existing in small pamphlets which were passed from hand to hand secretly. And finally it was compiled by the Roman church with a number of learned men, keeping a few of the gospels and a few of the letters writ  相似文献

Morrison’s The Bluest Eye begins with a fragment—a triply-repeated story.In the second narration,all punctuation disappears,along with the capital letters.In the third telling,the spacing between the sentences fades,which creates a sense of incomprehensible linguistic chaos.A stylistic approach is adopted to interpret underlying meanings:insanity of the protagonist Pecola and dark sides of American society.Methodically,it is the first time that optics is employed to interpret story,and stylistics can nourish itself from natural sciences.  相似文献

I first heard this tale in India, where it is told as if true-though any naturalist would know it wouldn't be. Later someone told me that the story appeared in magazine shortly before the First World War. That magazine story, and the person who wrote it, I have never been able to track down.The country is India. A colonial official and his wife are giving a large dinner party. They are seated with their guests-officials and their wives, and a visiting American naturalist- in their spacious  相似文献

Some time ago, really, let me be more precise, many years ago, I went for a job interview. Halfway through the interview, one of the interviewers asked me a question,“lf someone robs his victim using a gun with a bullet in it, should he be punished more severely than if he uses a gun that does not have a bullet in it? "What's the difference?"I got a quick response for that one. lsn't it true that if a person robs a victim with a gun, only the robber knows whether or not the gun is loaded, but the victim has no way of knowing it?The gun is used to threaten the victim into submission, and a crime is committed. Why should there be a difference between the sen-tence of a person committing robbery with a gun that has an empty chamber and a person robbing while holding a gun with a bullet in it? Of course I didn't get the job - I guess I didn't need a job then anyway.  相似文献

无论是"自涉"还是"非自涉",只有它们产生假(或矛盾)句时才应被禁止;一个论题是否称为"悖论",要看它的"严肃性(牵动重大、举足轻重)"或"论争性(扑朔迷离、悬疑难决)"而定.这个广义"悖论"属下可有多个狭义.这样,我们首先抛开"自涉"、"悖论"而把"谎者"论题极度简化为"矛盾"论题并消解,最终表明了西方解悖雄师"尽墨"!  相似文献

“金谷之会”曾是影响极大的盛事。但在历史尘埃中已尘封千余年之久。重新审视这一历史个案。考察其在文学发展中的作用,可以发现,与邺下集团的西园之会相比,金谷之会可说是我国第一次真正的文人聚会与集体创作活动。与建安年间曹氏的文学观念相较,石崇的文学思想首次体现了文人意识与纯文学创作观念的觉醒,突破了传统的三不朽藩篱。再从“二十四友”的创作实绩看,它对西晋文学的繁荣功不可设,对后代文人创作的影响也是深远的。  相似文献

突发公共安全危机可以分为外源性和内源性两类。如果说,对于国与国之间爆发的“外源性”危机的管理首先是一种“维护面子”的行为,则一个政治系统内部发生的“内源性”公共安全危机的管理首先应该是一种“社会动员”行为。任何社会动员行为都可以看作首先是一种言语行为,而作为“社会动员行为”的言语,为了确立社会动员行为的合法性和有效性,一个基本语用规则就是应该“实话实说”。但是,在危机管理中,却可能出现:政府在“实说”,但听众却并不以为是“实话”。由此,“实话如何实说”便成为一个值得分析的问题。  相似文献

心理的本质应该是“知”(觉知),因为“知”乃是一切心理意识现象的特征品质,且与其是性命悠关的:有“知”则有心理在,“知”一丧失则心理也消失了。但其他各种别的“心理本质”,如理性、自由、反映和意向性等实际都不够心理“本质”的资格,因为还存在着多种非理性、非自由、非反映性和非意向性的心理意识现象,故这些性质不是一切心理现象皆具备的。“知”(觉知)是最基本的心性,常被熟视无睹,但它却是最深奥的概念之一,因而也最适合表征心理的本质。对“知”的长期忘忽已经耽搁了对心理意识的本质把握和深入理解,并造成了许多不当的纷争。  相似文献

《红楼梦》续书作者高,旧有“传胪”之称。查“传胪”本为宣布进士名单的仪礼行为,后由动词转化为名词,成为进士名单中的专用称谓。明代科举,“传胪”并指二甲、三甲第一名;清代科举,则偏指二甲第一名。根据有关资料,高于乙卯恩科所中名次为三甲第一名。就清代科举制来说,称其为“传胪”,实不够准确;但放在明清文化大背景中,称其为“传胪”亦非全无根据。  相似文献

公平的本意是“合情合理、不偏袒”,是公正与平等的有机结合,且重心在公正,是一种“应该如此”的价值判断,具有永恒与普世的价值。“效率优先,兼顾公平”仅仅将“一定程度的收入均等化”视同为公平,并由此出发探讨公平与效率的关系,存在难以克服的硬伤:忽略了公平中的公正要求,与公众日常生活中“合情合理、不偏袒”的公平观不兼容,极易引发种种悖论,误导价值观的混乱。放弃“效率优先,兼顾公平”的提法,取而代之以“维护与实现公平(正义)”,不可避免。  相似文献

《逐贫赋》并非运用了拟人和想象,其中的“贫”实系西汉民俗信仰中的“贫鬼”,与此相关的民俗为“除贫”。《逐贫赋》第一次以文学艺术的形式回答了文化史上一个重大命题:当被政治的浊流冲击到社会生活的边缘以后,作为一个文化人应该以什么方式完成文化使命,实现人生价值。  相似文献

“林泉之心”从美学的角度理解,具有二个层次的内涵。一是抱着平等亲爱的心态,与林泉为朋。二是人情人性与山水的共鸣,移情作用的体现。它告诉我们,只要拥有发现山水之美的“林泉之心”,大可以不必隐逸到山水之中,在现实社会中同样可以获得山水之乐。郭熙的“林泉之心”就是美学中的审美心态,是人生的一种境界。  相似文献
