This paper tries to analyse the dramaturgy of the famous ancient Greek tragedy Oedipus The King with the relevant theory in Potics by Aristotle, involving elements such as peripeteia, anagnorisis, pathos, and the relationship between ethos and praxis,etc.

本文试以亚里士多德《诗学》中的相关理论分析古希腊著名悲剧《俄狄浦斯王》的编剧法，涉及到包括突转、发现、苦难、情节与性格的关系等诸要素。

A predator model with refuge and toxicity is studied. By constructing a suitable Dulac function, it is shown that there is no limit cycle in the first quadrant, thus the globally stability of the equilibrium is proved. Further more, the paper analyzes the influence of refuge, toxicity and harvesting. It is amazing that ① if the death rate of predator is big or the harvesting effort is big, the existence of the predator is unrelated with refuge; if the death rate of predator and the harvesting effort are small, and the refuge is small enough, the population of both species is increased as the increase of refuge;② if d2=0, the increase of d1 has no influence on the prey population, while the population of predator is decreased.

研究一类有避难所、毒素作用和外界捕获影响的捕食系统，通过构造恰当的Dulac函数，证明系统在第一象限没有极限环，从而证明了平衡点的全局稳定性；分析了避难所、毒素、捕获作用对该系统最终种群数量的影响，发现：①当捕食者的死亡率大或其被捕获得多时，两种群的绝灭与避难所的存在无关；当捕食者的死亡率小、被捕获得多且避难所足够小时，随着食饵避难所的增加，捕食者种群数量也随之增加；②当毒素d2=0时，毒素d1的增加对食饵种群最终数量没有影响，而使捕食者种群数量下降。

Kennedy et al [4] reported changes in the ethmoid bone in pathology specimens taken from individuals with CRS. These changes were similar to those seen in osteomyelitis and could play a role in failure of oral antibiotic therapy.

Kennedy等[4]发现，慢性CRS的筛窦有类似于骨髓炎一样的改变，这可能是口服抗生素用于治疗慢性CRS经常失败的原因。

Then find out that ethyl ether can absorb the UV-light, the wavelength of that is lower than 304 nm, and can produce strong fluorescence.

发现，乙醚能吸收波长小于304 nm的紫外光，产生强的荧光；乙醚的荧光峰是波长306 nm至345 nm范围的宽谱峰，峰值波长在317 nm左右。

It's only a vestige of Eurocentric imperialism that leads us to think of America as having been "discovered" in the traditional sense and it's left many people who are native to the continent with the feeling that their pre-Columbus history has been ignored and devalued.

这只不过是因为人们长久以来以欧洲文化为中心的思想使得我们认为美洲大陆是被"发现"的。这也使得那些天真的人忽略了在哥伦布之前的美洲大陆的历史。

ENGLAND'S Lake District was "discovered" in the 18th and 19th centuries by a succession of brilliantly manic visionaries. Since then its blameless fells and lakes have served as a backdrop on which English sensibilities have been fervidly projected. Native idiosyncrasies such as Picturesque and Romantic ideals, the National Trust and National Parks are organically bound to the area.

自从18世纪、19世纪一连串聪明又狂热的幻想家"发现"了英格兰的湖区，它便跃入了世人眼中，于是，在这里激情地上映着英国独有的敏感性，于是本地的特性，诸如画意和罗曼蒂克的理想，和这里的国家公园，以及保护名胜古迹的民间组织——国民托管组织，有机的组织在一起。

According to the synthetic methods study of the quinolones, it is found that the synthetic method of parent ring is of wide use by the condensation from α-substituted aryl formyl-β-substituted aminoacrylic acid and the inner molecular nucleophilic substitution reaction, which is almost suitable for the quinolones preparation of different rings or different substituted groups in 〓-position.

然后，对其合成方法进行了归纳，发现：由α-取代芳甲酰基-β-取代氨基丙烯酸缩合，经分子内亲核取代反应形成喹诺酮母环的合成方法用途非常广，几乎适用于所有不同环系或〓-位是不同取代基的喹诺酮类衍生物的制备。

It is shown that many of the existing integral transforms (including their logically equivalents) such as chirplet transform, dispersion transform, wavelet transform, chirp-Fourier transform, short-time Fourier transform, Gabor transform, Fourier transform, cosine transform, sine transform, Hartley transform, Laplace transform, z transform, Mellin transform, Hilbert transform, autocorrelation function, cross-correlation function, and the energy and mean of a signal, can each be considered as a special case of the FMmlet transform with specific parameters. In fact, an inventory of subspaces of FMmlet transform runs into countless numbers. The subspaces mentioned above are merely a few among a zoo of subspaces. They are essentially obtained by cutting the transform space of FMmlet transform at different positions, and can be likened to the computed tomography in medical diagnosis. Through these subspaces we actually see different slices or profiles of the FMmlet transform.

将现有诸多变换置于统一的 FMmlet 变换中加以审视，发现 chirplet 变换、频散变换、小波变换、 chirp-Fourier 变换、短时 Fourier 变换、 Gabor 变换、 Fourier 变换、余弦变换、正弦变换、 Hartley 变换、 Laplace 变换、变换、 Mellin 变换、 Hilbert 变换、自相关函数、互相关函数、能量和均值等，均为 FMmlet 变换在其参数取特定值时的特例；上述诸变换之间的差别，主要在于变换空间的维数有别，以及在不同空间维上取值的不同；这些变换有如医学诊断中的 CT，均由压缩 FMmlet 变换域空间所致，可以说我们通过这些变换看到的，是 FMmlet 变换的不同剖面。

The results were as follow:1 .The branches of N-glycans increased in serum of liver cancer patiens. Fucose structure increased and Fucoseα-1,6GlcNAc existed in serum of liver cancer patiens.

利用凝集素芯片分别对肝癌血清和健康人血清、正常肝细胞Chang\'s liver和肝癌细胞SMMC-7721膜蛋白、大骨节病人血清以及大骨节病对照血清和透明质酸治疗后血清进行了分析检测，发现：1。

Article 144 The Government of the Hong Kong Special Administrative Region shall maintain the policy previously practised in Hong Kong in respect of subventions for non-governmental organizations in fields such as education, medicine and health, culture, art, recreation, sports, social welfare and social

第一百四十四条香港特别行政区政府保持原在香港实行的对教育、医疗卫生、文化、艺术、康乐、体育、社会福利、社会工作等方面的民间团体机构的资助政策。原在香港各资助机构任职的人员均可根据原有制度继续受聘。

Small wonder, then, that the Chinese spend more in the shop than any other group of foreign visitors do .

这样的小惊喜，使中国顾客比任何国家的人消费得更多。
