For example, this wine agent is concerned withmatching foods and wines, so it may have both free and purchasable information on this topic such as the Wine Spectator's article on matching food and wine (http://www.winespectator.com/Wine/Wine_Basics/Wine_Basics_Template/0,1199,17,00.html).

比如，这个葡萄酒主体是关于食物和酒的匹配方面的，所以它可能通过免费的或者付费购买的方式得到的这一主题的信息，例如像评酒者上的关于搭配食物和酒

Although Zakaria's print and television appearances over the past two years may lead readers to assume that his book is about the "clash of civilizations" between Islam and the West, most of it is about what Zakaria regards as the excessive respect for pure democracy in the United States—the reliance on polling, the popularity of ballot initiatives, the insistence on making all institutions "answerable to the public."

虽然扎卡里亚在过去两年里的出版和电视曝光可能引导读者去设想他的书是关于伊斯兰和西方之间"文明的冲突"，它大部分内容是关于扎卡里亚所谓的美国对纯粹民主的过分器重——对投票的依赖，创制投票的流行，坚持所有的机制都要"对公众负责"。

After many experiments with aluminium foil of various thicknesses he was able to publish, in 1894, his great discovery that the plate of quartz that had, until then, been used to close the discharge tube, could be replaced by a thin plate of aluminium foil just thick enough to maintain the vacuum inside the tube, but yet thin enough to allow the cathode rays to pass out.

1888年莱纳德在海德堡大学昆克手下工作，他完成了他关于阴极射线的第一项研究成果，他研究了当时赫兹关于阴极射线有与紫外线相似特性的观点，并设计了一个实验，以探究阴极射线是否像紫外线一样，能够通过放电管壁上的石英窗，他获得的结果是阴极射线没有这样的特性。

We first introduced a new concept called transitive resolvable idempotent symmetric quasigroup, proved that the necessary condition for the existence of TRISQ is also sufficient, then presented a tripling construction for LKTS by using TRISQ instead of TKTS, thus removed the condition "there exists a TKTS" in Denniston''s tripling construction for LKTS; We also improved J. Lei''s product construction for LKTS by removing the condition "there exists a TKTS".

我们首先引入了可迁可分解幂等对称拟群的新概念，证明了TRISQ存在的必要条件也是充分的，然后给出了用TRISQ取代可迁Kirkamns三元系的LKTS的三倍构造法，这样就去掉了在Denniston的关于LKTS的3倍构造中的条件"存在一个TKTS"；我们用TRISQ取代TKTS改进了雷建国的关于LKTS的一个积构造方法，从而去掉了该构造方法中的条件"存在一个TKTS"。

Before Quesnay and the French economists there existed only a practice of political economy which was exercised by the State officials, administrators, and authors who wrote about matters of administration, occupied themselves exclusively with the agriculture, manufactures, commerce, and navigation of those countries to which they belonged, without analysing the causes of wealth, or taking at all into consideration the interests of the whole human race.

在魁奈一派法国经济学家以前，只有在实地应用下存在的政治经济学，那是由公务人员或行政官们来执行的；至于叙述这类问题的作者，他们所写的只是属于他们自己国家的农工商业与海运业事项，完全以这一范围为限，关于财富的起因这类问题是不加分析的，关于全人类利益这类问题是绝对不予考虑的。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
