Visual carbon stars whose mid-infrared spectra are mainly dominated by photospheric continuum and show large excesses at 60um, represent a transition phase which follows an interruption of mass loss from the oxygen-rich phase and begins a new phase of the mass loss of carbon-rich material. Excesses at 60um in these stars are the emission from the residual of oxygen-rich material.

光学碳星的中红外能量主要来自光球，在60μm处存在超量发射，人们认为其演化阶段处在抛射富氧物质终止和新的富碳拱星壳层形成之间，其60μm超量发射就是富氧物质的残余效应。

沙伊称迪彭德拉当时身穿野战军的制服，挥舞着包括一支M-16突击步枪在内的数种武器，闯入正在王宫L形画室内举行的家族聚会。

Firstly, a homogeneous Harnack inequality as well as a maximum principle of nonhomogeneous subelliptic p-Laplace equations is proved by improving the classical Moser iteration method. The optimal estimate of m is also obtained through log |log| method.

首先改进经典的Moser迭代方法，证明了非齐次次椭圆p-Laplace方程的极大值原理和齐次Harnack不等式，并利用log |log|方法给出了不等式右端指数m的最佳上界估计。

Super surfactant: Made from petroleum sulphonate, this product can lower the interfacial tension of oil and water to 10-4mN/m. It can widely be used as oil displacement agent in oil field and improve the output of oil greatly. It has a good benefit and a wide market prospect.

超级表面活性剂：以石油磺酸盐改性制得；该产品降低油/水界面张力可达10-4mN/m，可广泛应用于油田驱油，能大幅提高石油产量；效益明显，市场前景广阔。

Nathan Mayer Rothschild started his London business, N. M. Rothschild and Sons in 1811 at New Court in St Swithin's Lane, City of London, where it still trades today. In 1818, he arranged a 5 million loan to the Prussian government, and the issuing of bonds for government loans formed a mainstay of his bank's business.

内森·梅耶·罗斯柴尔德(老梅耶·罗斯柴尔德之子，译者注)1811年在伦敦的圣瑞辛巷新场设立了N·M·罗斯柴尔德父子公司，由此开始了他在伦敦的生意，这家公司至今仍在营业。1818年，他为普鲁士政府提供了五百万英镑的贷款，政府贷款债券的发行成为了其银行业务的支柱。

设计了一种基于光纤饱和吸收效应的环形单纵模光纤激光器结构，以可调谐光纤布拉格光栅作为波长选择器件，与2 m未抽运掺铒光纤一起位于环形腔反射臂上。

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.
