He must have utterly forgotten or wilfully ignored the great desaster Napoleon brougt upon himself by attacking Russia early in the ninteenth century.

我从历史中认识到，人们从来都不从历史中吸取教训。是不是遇到哲学家讲的东西都要翻译得那么复杂呢？

The title and bill of material in engineering drawings are important data source for product data integrated management. In order to reuse the CAD data, the paper presents an effective method for extracting part information from existing engineering drawings. Through analyzing the format of title and bill of material, several shape-position characteristics of tables are summed up from the view of macro-layout and microstructure. A new method to automatically extracting drawing information based on cell-grid and feature-point is proposed along with its algorithm principle and implementation steps. A software package based on the method mentioned above is developed and used in practice.

1引言工程图是工程设计的主要成果和制造加工的主要依据，CAD软件的广泛应用使得传统上对于纸质图纸的管理模式转变为对大量电子文件的管理模式·由于文件系统在实际应用中不能适应复杂大规模的管理模式，已经出现了各种各样的图档管理系统[1]·工程图中包含的零件信息在表现形式上体现纸格式的标准化为批量提取数据提供了可能性·作为计算机处理的对象，图纸信息自动识别成为数据管理和系统集成的一项关键技术·当前CAD管理系统所处理的数据对象比较复杂，面临由不同企业使用不同的绘图软件生成的图纸，其中的标题栏和明细栏或者由软件自动生

The SPLT is shown to explain a wide range of processing complexity phenomena not previously accounted for under a single theory, including (1) the lower complexity of subject-extracted relative clauses compared to object-extracted relative clauses,(2) numerous processing overload effects across languages, including the unacceptability of multiply center-embedded structures,(3) the lower complexity of cross-serial dependencies relative to center-embedded dependencies,(4) heaviness effects, such that sentences are easier to understand when larger phrases are placed later and (5) numerous ambiguity effects, such as those which have been argued to be evidence for the Active Filler Hypothesis.

SPLT可解释范围宽广的，非先前在一个单一理论下可说明的处理复杂性现象，包括（1）与受词抽离关系子句相较，主词抽离关系子句的低复杂度，（2）为数众多的跨语言间的处理超载效果，包括多层中心嵌入架构的不可接受性，（3）相对於中心嵌入依赖性，跨序列依赖性的低复杂度，（4）当较大的片语放在后面时，使句子较易理解之沈重效果，以及（5）许多的模糊效果，例如那些被争论为主动充填理论之证据者。

Unfortunately, our mind is used to complication and it takes time to unlearn bad habits.

不舒服？我们的心灵习惯了复杂，它让我们不学习坏习惯上花时间

Based on different structure types, the slide shoes are designed in symmetrical and dissymmetrical, continuous and discontinuous types, therefore, the loading technique is characterized by diffcult operation, high technical requirements and complex process.

由于结构物类型不同，滑靴的设计有对称与不对称、连续与不连续之分，因此滑移装船作业难度大，技术要求高，工艺复杂。

Information security usually adopt coding and information hiding technology ,though digital watermark belongs to information hiding technology ,its signification and application intention are different with information hiding .The hiding information is similar to the protected color of animal ,because the sneak can not ensure whether there is hiding information when he face a great deal of information to avoid of attack .Digital watermark is enchased into multimedia product to identify copyright data .

大多数时间域水印算法提供简捷有效的水印嵌入方案，且具有较大的信息嵌入量，但对语音信号处理的健壮性较低；变换域水印算法则具有较强的抵抗信号处理和恶意攻击的能力，但嵌入和提取过程相对复杂；压缩域水印算法是直接把水印信号加在压缩音频上的方法，它可以避免压缩算法编解码的复杂过程，但稳健性不高，而且能够嵌入的水印容量不大[2][14]。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
