物质的改变

Moreover, human activities play a more and more important role in the development of tidal flat. The concentrated coastal engineering change the dynamic environment of the tidal flat, and the exploitation of oil, natural gas and groundwater results in surface subsidence in the coastal area. In addition, sea level rise and the accompanied increase of storm surge frequency and intensity, will strengthen the erosional process, reduce the tidal flat area, coarsen the sediment, made the slope steep, and cause other environmental effects.

人类活动的环境效应对渤海潮滩发育的作用越来越明显，环渤海地区密集的海岸工程将改变原始的潮滩动力环境；石油、天然气、地下水的开采会导致海岸带发生地面沉降；海平面上升以及与其相伴随的风暴潮作用频率与强度的增加都将会使渤海潮滩的侵蚀过程加强、潮滩面积缩小、滩面物质粗化、坡度变陡，并产生一系列的相关的环境效应。

This is Einstein 10 years of deliberation and exploration results, which in the 19th century to a large extent solved the crisis of classical physics, Newtonian mechanics changed the concept of space-time, it has exposed the considerable material and energy, the creation of a new world of physics, modern physics is the greatest revolution.

这是爱因斯坦十年酝酿和探索的结果，它在很大程度上解决了19世纪末出现的古典物理学的危机，改变了牛顿力学的时空观念，揭露了物质和能量的相当性，创立了一个全新的物理学世界，是近代物理学领域最伟大的革命。

On the basis of criticizing economism and consumerism,it differentiates two layers of the material demands of man,putsforward the idea of proper demand,and promotes the all-rounddevelopment of man;through the objective analysis aboutanthropocentrism,it goes from social ethics to environmental ethics,emphasizing the transformation of the man's conquest over nature andplundering attitudes toward culture and the urgency and significanceto build the relationship of harmony and coexistence with nature;itsshows the fresh value tendency to publicize the ecological culture.

它在批判实利主义和消费主义的基础上，区分了人的物质需求的两个层次，提出适度需求的新观念，并倡导人的全面发展；它对人类中心主义进行了客观分析，从社会伦理走向环境伦理，强调了改变人类对自然的征服、掠夺式文化态度，与自然建立和谐共生关系的急迫性与重要性；它表现出张扬生态文化的鲜明价值取向。

In a relatively brief period the archaeological record is reduced to mere scraps of stone, bone, glass, metal, and earthenware.

战场上军队的行动可能&改变历史的进程&，但从考古学的观点来看，这同样是难以捕捉的；可能更糟的是，多数有机物质会腐烂。

Yet they leave no sort of traceinthe archaeological records unless they are captured by a dictaphone or written down by a clerk.

So even if the bugs and their secreted proteases do not chop your sample into bits, they can degrade reagents, alter the pH of the solution, or generate chemical species which can influence crystallization and even make reproducing conditions a pain in the tush.

就算这些可恶的家伙们没有将你的样品&嚼碎&，它们也可能影响你的试剂，改变溶液的pH，产生可能干扰结晶的化学物质，使得你的实验很难重复出来。

In conclusion, tobacco specific carcinogen, NNK, enhanced colon cancer metastasis through α7-nAChR and E-cadherin — one of the hallmarks of epithelial mesenchymal transition — and its transcription repressors, Snail and ZEB1. Besides, the nicotine also enhanced the colon cancer cell migration through non-E-cadherin pathway.

从我们的实验得知菸草中的致癌物质NNK能透过结肠癌细胞上的α7尼古丁受器而改变E-cadherin转录及其转录抑制因子(Snail和ZEB1)的表现量来增加结肠癌细胞的转移能力，而尼古丁则是透过E-cadherin以外的途径来促进结肠癌细胞转移。

Yet their discoveries—from planets around other stars that may support alien life, to dark matter and energy of unknown nature that are the dominant stuff of reality—are no less world-changing than his.

然而他们的探索成果从支持外星生命体的其他恒星的行星的发现，到暗黑物质和未知自然界能量发现都对改变世界产生巨大的影响，这一点并不逊色于伽利略。

These methods oftenyield widely different results so that the results must be traceable to the referencemethod to assure the accuracy and comparability.In 1964 the Expert Panel on Haemoglobinometry of ICSH drew uprecommendations for haemoglobinometry in human blood that were published in1967. The method had been revised three times; the apparatus, reagent and procedurehad been changed. We have established the reference method in our laboratoryaccording to the requirements of ICSH. Its methodology characteristics need to bevalidated whether the method is fit for charaterisation of haemiglobincyanidereference material.

国际血液学标准化委员会于1967年确定了血红蛋白的参考方法，至今该方法已修订三次，仪器、试剂、操作程序等都有改变，本实验室按照ICSH的要求建立了血红蛋白测定的参考方法，为了验证血红蛋白参考方法用于标准物质定值的可行性，我们对血红蛋白测定参考方法的性能进行了评价。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
