抽取式的

Methods The clinical symptoms of 148 cases with rotary abortion were observed routinely and compared with that of the approximate number of cases selected randomly with suction abortion.

按照人工流产的常规对施行旋动式流产的148例情况进行总结，并与随机抽取的近似数量的负压吸引人工流产做简单的对比分析。

In every group, rabbits were subdivided into experimental and control subgroups. 2 Rabbits were bullets injected followed by continuous injected with 13C labeled leucine, glucose, and lactic acid; 3 Blood were drewed before and 150, 160, 170, and 180 min after the initiation of isotopes injection for material analysis; 4 Exhale gas were collected every 5 min in the first 30 min followed by every 30 min there after for material analysis; 5 After centrifuge in low temp the supernatant of the blood samples were collected and went through axon and anon exchange column treatment; 6 Treated blood sample was used for 13C labeled leucine, glucose lactic acid examination through mass spectrograph; 7 The exhale gas was collected for 13CO2 exam through gas-phase mass spectrograph; 8 CO2 total production rate (V13CO2), body various substances production, oxidation speed, and substances metabolic percentage all can be calculated through equations provided by references below; 9 Data was processed through student t test.

分亮氨酸、葡萄糖和乳酸三组各取健康新西兰兔16只，每组再分为高代谢脓毒症组和对照组两部分，建模方法同第一部分；2）三组分别先静脉弹丸式推注再持续灌注13C标记的亮氨酸、葡萄糖和乳酸；3）灌注前抽取动脉血作为背景值，灌注达150，160，170和180min分别抽取动脉血2ml用于质谱分析；4）实验开始后前30min中每5min收集呼出气一次，随后每30min收集呼出气一次，用于气相质谱分析；5）血样经过低温离心取上清液，过阳离子及阴离子交换树脂，再经衍生化处理；6）处理过的血样进入气相色谱－质谱仪，测量其13C标记的亮氨酸、葡萄糖和乳酸丰度；7）实验兔的呼出气通过13CO2气相质谱分析仪测定其中的13CO2丰度（E13CO2）；8）利用文献提供的公式算出CO2总生成率（V13CO2）以及机体各物质的通量、氧化速率以及物质代谢百分比等；9）数据分析处理采用t检验。

As an important component among information acquisition methods, the requirement for high quality auto-summarization system also becomes more urgency. To fulfill this requirement, an adapted Dotplot methods based on word sense quantization model is firstly provided to address the problem of subtopic segmentation. Then a multi-knowledge-sources-integrating model is constructed, which combines the results of rhetorical structure analyse, text content structure analyse and subtopic segmentation together and provides clues for abstract sentences extracting.

第四，互联网的普及增加了人们对信息获取速度、准确率的要求，也推动了人们对自动文摘系统的需求，为了进一步改进现有文摘技术，本文首先研究了基于语义量化模型的改进Dotplot隐式章节划分算法，然后通过加权有向图来构造了一个多知识源融合模型，模型能够融合文本修辞结构分析、内容层次结构分析以及隐式章节划分等多种知识源的分析结果，并以此为基础建立文摘语句的抽取算法。

Methods:150 cases of spontaneous pneumothorax which were randomly collected since 1995 were devided into two groups.in group a thoracic close drainage plus lasting vacuum aspiration（0.5～1.5 kp） was applied by deep vein detained trochar in 65 cases.

将1995年以来随机抽取的150 例需进行胸腔闭式引流术治疗的自发性气胸患者分为两个治疗组。a组：65例使用深静脉留置套管针行胸腔闭式引流术加持续低负压（0.5～1.5 kpa）吸引治疗自发性气胸。b组：85例常规大导管组治疗自发性气胸。两组结果进行比较。

Starting in the 1970s, for example, the World Bank made low-interest loans enabling the government of Bangladesh to import diesel pumps for deep tube wells, a technology used in Nebraska to pull water out of the Ogallala aquifer.

举例来说，自从1970年代起，世界银行以低利贷款让孟加拉国政府进口管式深井用的柴油泵；美国内布拉斯加州就是利用这种技术，来抽取奥格拉拉地下蓄水层的水。

The integration of the in-situ chemical oxidation, the air sparging and soil vapor extraction is an innovative technology. However, as the domestic remediation cases are concerned, the local contractors use gravitational injection to inject chemical oxidants in order to save cost.

现地化学氧化法整合空气曝气法及土壤气体抽取法系统为一项创新的技术，而国内现阶段之整治案例，厂商为节省成本考量化学氧化剂注入方式系以重力式注入为主。

The activation energy of B ring elementary reaction is between 16～20kJ/mol.

从IRC结果以及对过渡态结构的电子密度拓扑学分析结果可以确定，羟基自由基在反应过程之中抽取了黄酮类化合物A环上未参与分子内氢键结构的酚羟基上的氢原子形成水分子及稳定性更高的半醌式大环自由基，在整个过程之中羟基自由基从反应物一侧进攻并逐渐发生扭转，直至形成一个进平面结构的过渡态结构，这与上一章关于黄酮类化合物B环的研究结果基本一致。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
