Research on the prehistoric "Golden Age" establishes for this relationship the generant foundation of prehistory; the theory of inclination exp...

黄金时代&史前研究为其奠定了史前史的发生学基础，&归依体验&理论为其提供了审美心理学的印证，&回归自然的主张和实际行动为其出具了历史实践证明，著名思想家的代表性论述为其积累了极富启迪的思想资料。

At present it is widely accepted that the damages of the nasal turbinate bones and mucus caused by Bordetella bronchiseptica laid the foundation for the invasion toxigenic Pasteurella multocida. The mixture of Bordetella bronchiseptica and toxigenic Pasteurella multocida, together with some other factors, is the main cause of natural AR.

经过多年研究，现在大多数学者认为，支气管败血波氏杆菌能引起一定程度的鼻粘膜和鼻甲骨损害，但这些病变的严重后果是为正常猪鼻腔不能定居的产毒素多杀巴氏杆菌建立感染铺平道路，Bb和T+Pm的混合感染加上非传染因素交织在一起，是在自然条件下临床型AR的发生原因。

Dramatic changes in land use of western China have taken place since the beginning of the 21st century due to unique physiographical characteristics,and some complicated social,economic and political factors.These factors are closely related with land resources utilization relative to agriculture,forestry,and animal husbandry as well as sustainable development relative to urbanization and land degradation.

由于其特殊的自然地理特征和社会、经济、政治等驱动因素的复杂多变，本区的土地覆盖发生了很大的变化，这些变化同农业、林业、牧业等与土地资源利用有关的产业发展以及城市化和土地退化等可持续发展问题密切相关。

Results 42 of 45 patients had a history of subarachnoid hemorrhage for 1 to 3 times. 23 and 22 cases died separately before and after digital substract angiography. 5 cases of rebleeding was relating to angiography, 24 cases died during the "high risk" period (4 to 10 days after first rupture). Rebleeding accounted for a 7.2% mortality of aneurysms preoperatively in our study. Among them, 71% was attributable directly to rebleeding, whereas 29% to non-neurological complications.

结果 45例病人中42例既往有1～3次蛛网膜下腔出血病史，住院后于数字减影脑血管造影前出血死亡者23例，造影后出血死亡者22例，其中5例出血与脑血管造影有关，24例再出血发生在动脉瘤自然出血高峰期内(4～10天)，住院期间出血死亡的发生率占我院同期动脉瘤总数的7.2%，直接死于再出血的为71%，死于非神经系统并发症的为29%。

When Kathryn Bigelow's The Hurt Locker won all the big Oscars over James Cameron's Avatar , the victory was perceived as a good sign of the state of things in Hollywood: A modest production meant for independent festivals clearly overran a superproduction whose technical brilliance cannot cover up the flat simplicity of its story.

当凯瑟琳毕格罗的《拆弹部队》力压詹姆斯卡梅隆的《阿凡达》获得全部奥斯卡大奖的时候，如是的成功便自然被视作是那些常在好莱坞发生之事的隐喻性浓缩：一部最初指向独立电影节的低成本制作明显胜过一部试图用华丽特效来掩盖苍白情节的超级大片。

Gene introgression is usually resulted from spontaneous hybridization occurring among closely related species in sympatric populations and thus has great impact on genetic structure of natural populations.

同域分布的近缘物种常常发生杂交而导致种间基因渐渗，从而对相关物种的自然居群遗传结构产生重要影响，近缘种间的杂交渐渗已成为进化生物学和保护生物学关注的热点。

Scientific readers were already aware of arguments that species changed through processes that were subject to laws of nature, but the transmutational ideas of Lamarck and the vague "law of development" of Vestiges had not found scientific favour.

科学文章读者已经知道物种通过受自然法则控制的过程发生改变，但拉马克的嬗变观念和《遗迹》中含糊不清的&发展规律&没有得到科学界的赞成。

Seldom except in books do the dying utter memorable words, see visions, or depart with beatified countenances, and those who have sped many paeting souls know that to most the end comes as naturally and simply as sleep.

书中描写的垂死之人会说出难忘的话语，看到幻想，或者带着极幸福的神态辞世，这些在现实生活中很少发生。那些多次送终的人知道，对大多数人来说，生命的结束如同睡眠一般自然、简单。

This research is a new low cost method of producing abrasive grit. It is to put the iron ore concentrate, coal powder, hydrated limed and addition agent together to make coal mixed pellet in prior which is rapidly auto-reduced in high temperature and kept about 10min above 1350℃, and then furnace cooled. The 2CaO·SiO2 of slag phase change、volume increase and natural bloom in reduction process. Finally we obtain no-slag abrasive grit through screen separation , in which the iron yield can be above 90%,the sulfur content can be below 0.05% and carbon content is lower than 4.0%.

本研究是一种全新的低成本生产铁粒的方法，它是将铁精粉、煤粉、消石灰和添加剂预先制成球团，在高温下迅速加热还原，在1350℃以上保温10分钟后随炉冷却，渣相中2CaO·SiO2在冷却过程中发生相变，体积膨胀而自然粉化，通过筛分便可以得到不含炉渣的铁颗粒，铁的收得率在90%以上、S≤0.05%、C在4.0%左右。

I believe that we're programmed at birth to produce endorphins when we're in close relationships.

我认为，我们的肌体在出生的时候就有这样的功能，即一旦发生任何亲密的关系就会产生内啡肽，使人与人之间保持亲密的关系纯属自然法则。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
