As for the software design, according to the features of angular deflection algorithm, the data processing way is designed as follows: whenever an isochronal packet is acquired, it is processed and the result is accumulated, and the processing of an image is completed when the transmission of the next image is started.

对于系统的软件设计，根据角偏差算法的特点，设计处理数据方式为：每采集一个等时数据包就对该数据包进行处理并将结果累加，到下一幅图像传输开始时完成对上一幅图像的处理。

对于随机变量噪声，通过用背景、白板、样品各组重复采集、递归平均再计算光谱数据的方法减小，同时可节省存储空间，减小三组数据的重迭区域，增加光谱数据的有效范围。

A mass of incomprehensible original data is extracted and inferred into meaningful and consultable data to some certain users. meanwhile, by network information processing, the data transmission account and latency are decreased; the energy efficiency and data accuracy are increased.

传感器网络的网内信息处理技术在原始采集数据的基础上，将大量的信息处理和计算移植到传感网内部进行，从海量的、杂乱无章的、难以理解的原始数据中抽取并推导出对于某些特定的用户来说具有特定意义和判决参考价值的数据。

Network information processing transfers the majority of processing and computing works into WSN based on original data collection. A mass of incomprehensible original data is extracted and inferred into meaningful and consultable data to some certain users. Meanwhile, by network information processing, the data transmission account and latency are decreased; the energy efficiency and data accuracy are increased.

Methods A single shot 3-D laser scanner, VIVID 910, was used to capture the craniofacial images of 227 patients. Only a top light was used during scanning. The patients sit up straight with their Frankfurt plane parallel to the horizontal plane, and the shot was 10° upper-wards. The scans were applied frontally and 80°bi-laterally, and the data were registratered, merged and processed with a general reverse engineering software. The usage time and the image quality were documented.

利用VIVID 910单镜头三维激光扫描仪扫描227例受试者的颜面三维影像，采用全室内顶置光源，受试者眶耳平面尽量与地面水平，扫描仪镜头水平抬高10°，使用14mm焦距镜头，于受试者正前方及双侧各80°位置采集数据，获得数据经通用软件拼接、二期处理，统计扫描及数据处理所需的时间及扫描结果质量。

In the paper,we introduce the application of DX120 Digital Limnograph in the water level observation of deep borehole at Beijing National Earth Observatory in briefly.

但我们在进行实时跟踪观测时，却发现一些不尽人意之处；如，要得到当天采集的数据需打开数据文件夹，将原始数据经过转换才能获取。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
