Where one might have been inclined to attend solely to the positive and general characteristics of studies of Chinese gardens that can be obtained from generalization and abstraction, I pursued the opposite direction of thinking toward particularity and exemplarity.

当很多人倾向于仅仅关注中国园林研究中那些绝对的和普遍的特征，然后通过抽象和普遍化的手段来完成；在这些地方，我则从一个相反的角度来思考中国园林研究中的特殊性和示范性。

Post-modernism reached music and painting at very similar moments, on one hand, the spareness, purity, love of mechanism, abstraction and the grid which are very modernist traits were preserved, as was the emphasis on personalizing style and experimentalism.

后现代主义的思想在音乐和绘画上的发生具有相似的情境。一方面，对于机械论式的诠释喜好逐渐降低，现代主义的手段被弃置；取而代之的是个人主义化的风格和实验主义。

On the other hand, the longer he stayed in the US, the more he is inclined to Chinese traditional culture. He drew upon Chinese calligraphy, a language that integrates both abstraction and expressivity, attempting to probe the melting of western and Chinese art in the contemporary context.

另一方面，他在美国生活的时间越长，他愈发怀想中国传统文化的价值，其中特别思考和借鉴了中国书法这种融抽象性和表现性为一体的艺术语言，从而旨在探索中西艺术在当代层面上的融合。

Video abstraction are composed of the shot key fames according to the time order.

然后对候选关键帧按照相邻帧间交互信息量的比较来提取镜头关键帧，最后将镜头关键帧按时序排列在一起形成视频摘要。

From the conclusion, in order to improve the total exploitation amount or the total recovery coefficient, the government should allow enterprise to increase these abstraction of production cost such as keeping simple reproduction fee, security production cost, and ground collapse compensation fee as the increase in the exploitation quantity; count the taxes and fees based on the reserves; accurately estimate thee resource taxes and compensation fees of one ton of coal; and impose the total fees and taxes to be worked out before exploitation or at least in a shorter period after exploitation.

根据研究结论，为了提高煤炭资源总的开采量或总的回采率，政府应允许企业随着总开采量的增加而增加对维简费、安全生产费用、地面塌陷补偿费等各项生产成本的提取；按照核定储量计征税费；准确的估计吨煤的资源税和吨煤的补偿费；在开采前或者在很短的时间内征收计算出来的税费总额。

The information abstraction from original E-mail (e-mail pretreatment) is the base in mail filter.

然而，大量垃圾邮件的泛滥，使得邮件自动筛选成为当前研究的热点，目前广泛采用基于规则和基于概率的方法[1][2]。

It would take an infinitively large database to capture the real world precisely data must somehow be reduced to a finite and manageable quantity by a process of generalization or abstraction.

为了获得真实世界的精确数据将需要一个无限大的数据库，但由于某种原因，这些精确数据必须通过概括或提取过程减小为有限且可以管理的小数据。

Using the MP2 method at the 6-311G level, the geometries of the reactants, transition state and products of the hydrogen abstraction reaction of isocyanic acid with formyl radical have been optimized. Changes of bond lengths of interacting molecules and the stationary point structures were discussed along the minimum energy paths.

在 UMP2/6-311G计算水平上，优化了标题反应的反应物、过渡态、产物的几何结构，沿最小能量途径讨论了异氰酸和甲酰自由基发生氢转移反应位能面上驻点的结构以及相互作用分子结构变化。
