In others, the abnormal ground-glass opacities are centrilobular and peribronchiolar in location, resulting in the appearance of ill-defined centrilobular nodules.

在有的病人，整个小叶异常的密度增高，而邻近的小叶表现正常；而其他病人毛玻璃样阴影可位于小叶中心或细支气管血管周围，如同边界不清的小叶中心型结节。

The mfVEPs of patients with glaucoma were statistically lower than those of normal subjects and negatively correlated with interpolated fields. In some cases the RAC of mfVEP between two eyes may be more sensitive to detect the visual dysfunction than the perimetry.

青光眼病人的中心视野转换为插值视野后，发现在青光眼病人的插值视野及mfVEP检查结果之间存在着明显的相关关系，个别病例提示mfVEP双眼间的不对称性改变可能会比中心视野的检测结果更加敏感。

Methods One hundred and forty eyes (77 glaucoma patients) were examined with the YDS201-type perimetry which by center-52 and a four-point threshold program to measure the center 300 visual field.

采用国产YDS-201自动视野计的中心52及四点阈值程序对77例（140只眼）青光眼患者在半暗室环境下检测中心30°视野。

Moreover,the main distribution character of Chinese Perlidae is that most of the species distribute Central China region,South China region and Southwest China region.The Central China region centralizes the distribution and the break of the perlid species,and made the dispersal for the others regions.

此外，郋科昆虫在中国的一个主要分布特点就是多数种类集中分布于华中区、华南区和西南区；而华中区则很可能是郋科种类的分化中心，并以此为中心向其他区扩散。

When using urea-hydroperoxide as oxygent, just the trimethylphosphine adsorbed on the Lewis acid sites in TS-1 zeolite was oxidized. It further confirmed that the hydroperoxo-titanium species formed by the interaction between the titanium in Lewis acid sites and urea-hydroperoxide are the active oxidation center, and the titanium in the framework as Lewis acid sites enhances the oxidation ability of hydroperoxide. 3. Phenylacetaldehyde and benzaldehyde are found to be the major products in the catalytic oxidation of styrene over TS-1 zeolite, and styrene epoxide is not as speculated detected.

当以过氧化氢尿素为氧化剂时，室温条件下吸附在TS-1分子筛Lewis酸性位的三甲基膦即能被氧化，由此进一步证明，TS-1分子筛中由Lewis酸性位的骨架钛与过氧化氢相互作用形成的过氧化钛物种是三甲基膦氧化反应的活性中心，骨架钛作为Lewis酸中心提高了过氧化氢的氧化能力。

Slaughtering and meat-packing centers arose in the early West, and by 1830s, Cincinnati, nicknamed Porkopolis, was the most important pork-processing city in the country.

屠宰与肉类的加工中心在早期的西部出了。19世纪30年代，辛辛那提已成为美国最重要的肉类加工中心。

There are two well-known shortcomings within K-Means algorithm prevailingly used in data clustering and other center-based clustering algorithms-the number of clusters must be known beforehand and the dependence of the algorithm performance on the initialization of the initial centers.

在聚类中广泛应用的K-Means算法及其它基于中心的聚类算法有两个共同的缺陷－需要预先确定类数目且随机初始化中心引起性能不稳定。

Reinhard Genzel obtained compelling evidence for this conjecture by developing state-of-the-art astronomical instruments and carrying out a persistent programme of observing our Galactic Centre for many years, which ultimately led to the discovery of a black hole with a mass a few million times that of the Sun, in the centre of the Milky Way.

莱因哈德E根舍对这个挑战性的猜测，找到了证据。他发展了最先进的天文设备，并持之以琣a对银河系中心进行长达数年的观测，终於笫一个获得确切证据，发现在银河系中心有一个黑洞，其质量是太阳质量的数百万倍。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
