数据采集

At present, the speed of acquitting data already has reach above 100 MSa/s in Data Acquisition circuit card of the Virtual Oscillograph.

目前，应用于虚拟示波器的数据采集卡，其实时采样速率在百兆赫兹以上的已经出现，而且还有很大发展空间。

Methods 24 patients known to suspect of having pulmonary embolism underwent MCTPA with 20 ml contrast medium. Scanning delay time was adjusted by using a test bolos. Contrast medium injection rate was 5.5 ml/s. The time of imaging data acquisition was 2-3 s. In addition 24 patients undergoing MSCTPA with 50 ml contrast medium were included in control group. Imaging quality was evaluated by five degree with blind method.

应用多层螺旋CT对24名疑似肺栓塞的病人行CTPA检查，对比剂总量为20 ml(300 mgI/ml)，以单层动态增强扫描所测时间－密度曲线的峰值时间为扫描延迟时间，对比剂注射速率5.5 ml/s，数据采集时间2~3 s；另随机选择24例常规对比剂剂量(50 ml) CTPA检查影像作为对照组，影像质量按5级行盲法评价。

The process of investigating and developing the electronic digital map of ground conductivities of China is introduced in this paper.

The performance of new system is increased greatly. Regarding the requiment of the system pattern and function,the system was constituted with a SOPC, programmable high voltage eradiating circuit,acoustic wave sample and all kinds of interface circuits.

根据非金属超声检测对系统结构和功能的新需求，本系统由SOPC系统、程控高压发射系统、数据采集以及各种接口系统组成。

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。
