In the past three or four years, the world wide web has given birth to a whole industry of point-and-click spying.
在过去的三四年中，国际互联网已经派生出一个可称为点击谍报的完整的产业。
The spooks call it "open source intelligence," and as the Net grows, it is becoming increasingly influential.
间谍们把它称为“公开来源情报”。随着互联网的增长，这样的情报变得越来越有影响力。
In 1995 the CIA held a contest to see who could compile the most data about Burundi.
1995年中央情报局举办了一个竞赛，看谁能够收集到关于“布隆迪”的最多信息。
The winner, by a large margin, was a tiny Virginia company called Open-Source Solutions，whose clear advantage was its mastery of the electronic world.
胜者胜出了一大截，却是弗吉尼亚的一家小公司，名为“公开来源解决方案”，它的明显优势是它对电子世界的把握。

换言之，在媒介机构的新闻采编室文化中存在着一套约定俗成的写作模式，为纷繁复杂的新闻报道提供了一个主干框架和一个现成的故事叙述结构。

By the time the American colonists took up arms against Great Britain in order to secure their independence, the institution of Black slavery was deeply entrenched.
当美洲殖民地民众拿起武器，抗击大英帝国，以获得其独立时，黑人奴隶制度早已根深蒂固。
But the contradiction inherent in this situation was, for many, a source of constant embarrassment.
然则，对许多人而言，这一情形中所固有的矛盾始终构成了一种窘迫难堪之源。
Upwards of a billion stars in our galaxy have burnt up their internal energy sources, and so can no longer produce the heat a star needs to oppose the inward force of gravity.
在我们的星系内，超过1亿多颗的星球已经耗竭了其内部的能源，因此产生不了一颗星球所必需的热量用于抗衡重力的内向力作用（the inward force of gravity）。
Another common misconception is that nuclear fusion power is a virtually unlimited source of energy because of the enormous quantity of deuterium in the sea.
另一个普遍的误解是，核聚变能量是一种几乎无限量的能源，因为海洋中存在着大量的氘。
The energy sources already in major use are in major use for good reason.
这些早就广为使用的能源之所以得到广泛使用，是有充分原因的。
The glycogen reserves of any animal are good, at most, for only about two minutes at maximum effort, after which only the normal oxidative metabolic source of energy remains.

Although much has been accomplished for the modern period, premodern cultures have proved more difficult: sources are restricted in number, fragmentary, difficult to interpret, and often contradictory.
虽然对现当代的研究成就斐然，但古代文化的研究要证明更为困难：资料来源数量有限，支离破碎，难于解释，且经常互相矛盾。
His work was based on a comprehensive survey of references in the ancient sources to Amazonian and other societies with matrilineal customs—societies in which descent and property rights are traced through the female line.
他的研究所依据的是对古代史料来源中的参考材料进行的综合考虑，而这些参考材料则涉及到亚马孙和其他带有母系（matrilineal）习俗的社会——在这些社会内，亲缘关系和财产所有权均经由女性这条线来追溯。
The sources that will probably tell contemporary historians most about women in the ancient world are such social documents as grave- stones, wills, and marriage contracts.
有关古代世界的妇女，对当代史学家可能最具价值的史料是这样一类社会性文献，诸如墓碑、遗嘱、和婚约。
Studies of such documents have already begun to show how mistaken we are when we try to derive our picture of the ancient world exclusively from literary sources, especially myths.
对这类文献资料的研究早已开始证明，当我们试图仅仅从文学来源，尤其是神话，来获取我们对古代世界的理解，这是多么的失误啊。
Alumina also occurs naturally as the mineral corundum, but corundum is not found in large deposits of high purity,and therefore it is an impractical source for making aluminum.
氧化铝亦作为刚玉（corundum）这种矿物质自然发生，然而，刚玉无法以高纯度、大储量被发现，因此，它不是一种切实可和的冶炼铝的矿源。
The best evidence for the layered-mantle thesis is the well-established fact that volcanic rocks found on oceanic islands, islands believed to result from mantle plumes arising from the lower mantle, are composed of material fundamentally different from that of the midocean ridge system, whose source, most geologists contend, is the upper mantle.
对于地幔分层论点来说，最好的证据乃这样一个确认的事实，即在那些海洋岛屿——这些岛屿据信是源于由下层地幔升上来的地幔柱状溶岩流（mantle plume）——上发现的火山岩石，是由与海洋中部山脊系统的物质根本不同的物质构成的，而这一海洋中部山脊系统的成因，大多数地质学家论辩道，为上部地幔。
However, near hydrothermal vents, areas of the ocean where warm water emerges from subterranean sources, live remarkable densities of huge clams, blind crabs, and fish.
然而，在热液排放口（hydrothermal vent）附近，即海洋中热水从地下来源涌出的区域，却生存着极为密集的巨形蛤蜊，瞎眼蟹和鱼类。
The first reports describing vent faunas proposed two possible sources of nutrition: bacterial chemosynthesis, production of food by bacteria using energy derived from chemical changes, and advection, the drifting of food materials from surrounding regions.
描绘热液口动物群的最初报告提出了两种有可能的营养物来源：细菌化学合成（bacterial chemosynthesis），即细菌利用来自化学反应的能量制造食物，以及平流（advection），即食物材料从邻近区域漂逐而至。
For example, some of the large sedentary organisms associated with vents are also found at ordinary deep-sea temperatures many meters from the nearest hydrothermal sources.
例如，与热液口相关的某些庞大静栖生物体在深涨常温条件下也在离最近的热液源好几米处被发现。
This suggests that bacterial chemosynthesis is not a sufficient source of nutrition for these creatures.
这表明细菌化学合成对这些生物体而言不足以构成一种充分的营养物来源。
Nonetheless advection is a more likely alternative food source.
尽管如此，平流是一种更有可能的可供替代的一种食物源。
The determination of the sources of copper ore used in the manufacture of copper and bronze artifacts of Bronze Age civilizations would add greatly to our knowledge of cultural contacts and trade in that era.
对于青铜时代（Bronze Age）文明中的铜与青铜制物来说，确定其铸造过程中所应用的铜矿石来源，可大大增加我们对那个时代文化交往和贸易的知识。
Researchers have analyzed artifacts and ores for their concentrations of elements, but for a variety of reasons, these studies have generally failed to provide evidence of the sources of the copper used in the objects.
科研人员已经对这些铜制物和铜矿石进行了分析，以确定各种元素的各种含量，但出于种种原因，这些研究普遍而言没能提供证据，以反映出这些物件中所使用的铜的来源。
And high concentrations of cobalt or zinc, noticed in some artifacts, appear in a variety of copper-ore sources.
在某些铜制物中注意到的钴或锡的高含量，亦出现在各种铜矿石来源中。
Isotopic composition, the percentages of the different isotopes of an element in a given sample of the element, is therefore particularly suitable as an indicator of the sources of the ore.
所谓同位素构成，是指在某一元素的特定样品中该元素不同同位素的百分比率。
同位素构成因此特别适合于作为铜矿厂来源的示踪物。
The ideal choice, when isotopic composition is used to investigate the source of copper ore, would seem to be copper itself.
当同位素构成被用来研究铜矿石的来源时，理想的选择似乎是铜本身。
The isotopic composition of lead often varies from one source of common copper ore to another, with variations exceeding the measurement error; and preliminary studies indicate virtually uniform is topic composition of the lead from a single copper-ore source.
铅的同位素构成经常在一种普通铜矿石来源与另一种铜矿石来源之间存在差异，其差异程度超出测量误差；而最初的研究表明，对于来自单独一个铜矿石来源的铅来说，其同位素构成几乎是毫无二致的。
Since the Hawaiian Islands have never been connected to other land masses, the great variety of plants in Hawaii must be a result of the long-distance dispersal of seeds, a process that requires both a method of transport and an equivalence between the ecology of the source area and that of the recipient area.
既然夏威夷群岛（Hawaiin Islands）从不曾与其它陆块相联，那么，夏威夷植物的巨大多样性只能是源自种籽的远距离播散，而这一过程则不仅仅需要某种传输方法，而且亦要求在来源地的生态环境与接收地的生态环境之间存在一种相同情形。
While most meteorites appear to derive from comparatively small bodies, shergottites exhibit properties that indicate that their source was a large planet, conceivably Mars.
尽管大多数陨石似乎都起源于相对较小的天体，但辉熔长无球粒陨石却展现出某些特性，表明它们的来源是某一颗庞大的行星，据信为火星。
In order to account for such an unlikely source, some unusual factor must be invoked, because the impact needed to accelerate a fragment of rock to escape the gravitational field of a body even as small as the Moon is so great that no meteorites of lunar origin have been discovered.
为了解释这样一种不太可能的来源，必须援引某个非同寻常的因素，因为一块岩石碎片要想逃逸出即使象月亮这么小的一个天体的重力场，使该岩石碎片加速所必不可少的撞击力是如此之大，以致于任何源自月亮的陨石从未被发现过。
The only other logical source of shergottites is Mars.
辉熔长无球粒陨石其它唯一合乎逻辑的来源就是火星。
The pictures were first published by The Sun newspaper in London. The paper reported it received them from a U.S. military source who hoped the humiliating photos would hurt the Iraqi insurgency, which has been conducting an intensified bombing campaign in recent weeks. The Sun quotes its source as saying the pictures show that Saddam is a "humble, old man now" and that they prove that his Baath Party is "never coming back."
照片最先登在伦敦出版的《太阳报》上。报纸报导说这些照片来自美军内部，提供这些侮辱性的照片的人说希望籍此打击伊拉克抵抗力量。伊拉克的抵抗力量几周来加强了炸弹袭击的力度。《太阳报》援引提供照片的人士的话说，萨达姆“现在只是一个卑贱的老头了”。这些照片可以证明萨达姆的复兴党“一去不复返了”。
"The women had identified such needs as the need for firewood, which is the main source of energy in the rural areas, the need for food, the need for clean drinking water, the need for building materials," she explained. "As you can see, all of those are fruits of the land. At that time also there was soil erosion because of deforestation of the upstream, especially up on the mountains. So I got this idea almost in passing that if we planted the trees we would be able to address some of these needs that the women had and we would be able to stabilize the soil. We started that way, but eventually it moved to other areas. It moved to issues of democracy, issues of human rights, women's rights, issues of peace. But initially it was a very basic activity of meeting the needs of rural women."
马塔伊说：“ 妇女们需要柴火，那是农村地区最重要的能源来源。她们需要食物和清洁的饮用水，还需要建筑材料。可以看出，这些都产自于土地，而当时由于上游的森林被砍伐，尤其是山里树木减少，造成了土壤流失。因此，我立刻想到，如果种树，就可以解决这些妇女的需要，并且可以保护土壤。我们就这样开始了，后来又扩大到其它领域，比如民主、人权、妇女权利以及和平等。而我们的初衷是解决农村妇女的基本需求。”
In 2003, Iranian officials admitted to the U.N. nuclear watchdog, the International Atomic Energy Agency, that they had been secretly developing nuclear capabilities for more than a decade. The IAEA admonished Tehran and insisted on snap inspections and a halt to its uranium enrichment program. As a signatory to the Non-Proliferation Treaty, the N.P.T., Iran is prohibited from developing a viable nuclear weapons program. Iran says its nuclear program is aimed at providing an alternate source of energy.
在2003年，伊朗官员向联合国的国际原子能机构承认，他们已经秘密进行了十多年的核试验。国际原子能机构警告了德黑兰政府，坚持要进行未经通知的临时检查，并要求伊朗停止浓缩铀计划。伊朗在禁止核扩散条约上签了字，因此它是不可以发展核武器的。但伊朗说，他们的核计划是为了开辟另一种能源。
Sources close to the organizers of the conference say it has been delayed at the request of the United Nations, which wanted more time to prepare. It is now expected to take place in mid-August.
与大会组织者关系密切的有关方面说，推迟是应联合国的要求，联合国希望伊拉克有更多时间准备这次大会。目前，会议可望在8月中旬召开。

This block contains a wide variety of disorders that differ
in severity and clinical form but that are all attributable to the use of one or more
psychoactive substances, which may or may not have been medically prescribed. The third
character of the code identifies the substance involved, and the fourth character
specifies the clinical state. The codes should be used, as required, for each substance
specified, but it should be noted that not all fourth-character codes are applicable to
all substances.
Identification of the psychoactive substance should be based on as many sources of
information as possible. These include self-report data, analysis of blood and other body
fluids, characteristic physical and psychological symptoms, clinical signs and behaviour,
and other evidence such as a drug being in the patient's possession or reports from
informed third parties. Many drug users take more than one type of psychoactive substance.
The main diagnosis should be classified, whenever possible, according to the substance or
class of substances that has caused or contributed most to the presenting clinical
syndrome. Other diagnoses should be coded when other psychoactive substances have been
taken in intoxicating amounts (common fourth character .0) or to the extent of causing
harm (common fourth character .1), dependence (common fourth character .2) or other
disorders (common fourth character .3-.9).
Only in cases in which patterns of psychoactive substance-taking are chaotic and
indiscriminate, or in which the contributions of different psychoactive substances are
inextricably mixed, should the diagnosis of disorders resulting from multiple drug use
(F19.-) be used.
Excludes: abuse of non-dependence-producing substances (F55)
