抽取的

Methods:To review120 patients who were first aid in pre-hospital by air-way during January 2005 to2007. make two groups Randomly,one were observation group, the other were controls by tradition methods.

总结2005年2月至2007年2月在院前急救中行气道通气的患者情况，随机抽取60例使用口咽通气管的患者作为观察组，并对应抽取60例传统方法气道通气患者作为对照组。

In the first approach the metadata extraction is viewed as a classification problem. Three statistic classification models, including Support Vector Machines, Perceptron with Uneven Margins, and Maximum Entropy are studied. The approach suffers from the problems of ignoring the variance in lengths of documents and ignoring the dependency of text units within documents. To solve the problems, our second approach takes the metadata extraction as a sequence data labeling problem and makes full use of the sequential information.

论文首先研究了基于分类的元数据抽取方法，考察了支持向量机、非对称间隔感知机和最大熵模型在ADME中的应用；然后针对分类方法中存在的忽略文档之间的差异、不考虑文档上下文等问题，提出了基于序列数据标注模型的抽取方法，并结合最大熵马尔可夫模型、投票感知机模型和条件随机场模型进行了研究；最后本文根据前两种方法的设计思想和优缺点，研究提出一种新的结构预测模型—— CDASP（Coordinate Descent Algorithm for Structure Prediction），并将其应用于元数据的自动抽取中。

The robustness of different extraction rules is discussed and the key element of constructing robust Wrapper is introduced. Extraction rules extract the information from web page into the destination schema, however, this is not enough, and the Web information extraction still has many new challenges.

抽取规则只解决了从Web页面抽取出数据至目标模式的问题，然而在互联网环境下，Web信息集成面临许多新的挑战。

Event Extraction is an important research point in the area of Information Extraction.

1引言事件抽取是信息抽取领域一个重要的研究方向。

Methods A total of 6 352 students were chosen by multi stage randomized sampling, the information of the students aged 7-8 were collected by face to face interview, students aged 9-18 by self administered questionnaire. Results The incidence rate of injury was 48.0%, and there were 30.4% of the students reporting had committed injury. Every injury case had 1.58 injuries during one year averagely.

用4阶段分层随机整群抽样方法抽取大城市、中小城市、一类农村和二类农村各3个县区进行调查，每个县抽取1所学校，共对6 352名学生进行调查，小学一、二年级学生面对面访谈，三～六年级学生在调查员和老师的指导下完成，初、高中生自填。

The mechanical pump is a direct drive rotary vane vacuum pump. It is used as a forepump for the diffusion pump, and to rough pump the degasser, the distillation, the distillate and the residue chambers.

Methods BMSCs isolated from rabbit iliac bone marrow were culture-expanded in vitro. The injectable tissue-engineered bone constructed from autologous PRP, FG, and BMSCs was cultured in vitro, and its biological characteristics were observed including the time of gel formation, histological features, seed cell survival and microscopic structures. Results The constructed injectable tissue-engineered bone began gel formation within 20 to 30 s, and after a week-long culture, the gelatine began to degrade, and numerous well viable fusiform cells could be seen to adhere to the bottom of the Petil dish, Scanning electron microscopy identified globular and olivary cells embedded in the fibrin glue, and numerous small particles could be seen around of the cells.

从兔髂骨处抽取骨髓体外培养BMSCs并诱导向成骨细胞分化，抽取兔自体动脉血提取PRP，以FG、BMSCs、PRP共同构建可注射型组织下程骨并体外培养观察其生物学特性如凝胶形成时间，组织学特点、细胞存活情况及其超微结构特征等结果构建的可注射型组织工程骨可在短时间内形成凝胶，体外培养1周时其中细胞生长良好，电镜下见纤维蛋白网格结构致密，种子细胞及血小板颗粒分布广泛。

The same procedure was carried out 14 days later. Results The temperature of inferior segment of esophagus was significantly increased at 60min. The temperature of physic liquor was significant higher than that of perfusion. The temperature of perfusion was becoming significantly increased at 5min (P.05). The WBC, PLT, ALT, AST, Cr and CO2CP of preoperative and postoperative had no significant changes. Only lightly peritoneum dropsy and infiltrate slight phlegmasia were observed postoperatively and 14 days later. There were no significant differences among groups.

结果 在60min时食道下段温度显著升高，灌注温度明显高于抽取温度，抽取温度5min时开始升高(P.05)；各组术前和术后WBC、PLT、ALT、AST、Cr和CO2CP无明显变化，组间比较也无明显差异；术后和术后2wk腹膜均见轻度水肿、少量的炎细胞浸润；吻合口见黏膜层有小溃疡形成，表面有渗出，组间无明显差异。
