2.3 论文摘要的阅读

论文摘要的阅读有助于理解（了解）科学意义和学习科技论文摘要的写作。阅读可分为粗读和精读。粗读只要求了解主要内容，精读是进一步的阅读。一种是科学意义上的精读，是为了精确而深刻地了解其科学内容，对不认识的词可借助工具，必要时可请教专家。另一种是为了学习科学论文摘要写作的精读，这就要求了解摘要写作中的人称、时态、语态和一些特殊用法（如外来语、缩写、人名、地名、专业学名、e.g.、i.e.、etc.、et al.等）。

Current medical imaging technologies allow visualization of tissue anatomy in the human body at resolutions ranging from 100 micrometers to 1 millimeter. These technologies are generally not sensitive enough to detect early-stage tissue abnormalities associated with diseases such as cancer and atherosclerosis，which require micrometer-scale resolution.（编者注：以上是描述一般规律用一般现在时）Here，optical coherence tomography was adapted to allow high-speed visualization of tissue in a living animal with a catheter-endoscope 1 millimeter in diameter. This method，referred to as“optical biopsy”was used to obtain cross-sectional images of the rabbit gastrointestinal and respiratory tracts at a 10-micrometer resolution.（编者注：叙述自己的实验及结果用过去时态，被动语态） tcx/xxHcV0H+OzLReAg+E7VPS5roqTdjx510HniJSFTQGCkxkV9cKve1rc7dUzDZ
