抽取

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。

It is still needed to do some work to determine the deformation parameter β2 for light odd-odd nucleus, like 6Li and to calculate all reaction channels by means of CDCC code simultaneously. It is important to measure the exclusive angular distributions of breakup fragments.In theory, the coupling channel equations have been deduced from one-dimensional to multi-dimensional barrier tunneling. The couplings between the entrance channel and the other channels have appreciable effects on sub-barrier fusion cross section. Instead of single fusion barrier,these couplings lead to a distribution of fusion barrier Dfus.

描述了已有理论，从简单的一维势垒穿透模型出发，引入多维势垒穿透和耦合道模型，证明入射道相对运动与碰撞核各种自由度的耦合导致熔合势垒的劈裂，较低的势垒有利于垒下熔合截面增强；给出了从熔合激发函数抽取势垒分布及从背角准弹激发函数抽取势垒分布的理论依据，以及它们的优缺点。

Methods(1)4 cities were chosen randomly according to their economic status and geographical location.(2)An autorefractor was used to detect the diopter in the preschool children from 20 kindergartens randomly selected from each of the 4 cities.(3)1%atropine ointment was applied to the c onjunctival sac of the children with suspect myopia for 3 days and the refractio n of light in their retina was then examined by a barred beam skiascope.(4)The eye axis and corneal curvature of the myopic children were measured.(5)The diop ter,eye axis,and corneal curvature were examined every 6 months during 1-year f ollow-up after the diopter was properly rectified.

(1)依经济状况和地理位置按随机原则抽取4市县；(2)从4市县中各随机选择20间幼儿园，对所抽取的在园学龄前儿童用自动屈光仪进行屈光筛查；(3)可疑近视患者予以1%阿托品眼膏涂双眼3d，由专人用带状检影镜进行视网膜检影验光；(4)确诊为近视的患者自愿进行角膜曲率和眼轴测量；(5)近视患者经适当的屈光矫正后，按要求进行为期1年的前瞻性随访，每半年进行1次屈光状态、角膜曲率和眼轴的检测。

First, a method for calculating semantic likelihood between two phrase is carried out. then use the likelihood to determine the title row or column of the table, the correlation between titles and fields is determined at the same time. base title of the table, a simply method is presented which can be used to calculate correlativity between this table and what we wanted to extract.

首先提出了一种短语语义相似度的度量方法，然后利用短语语义的相似度确定表格标题行，并对表格行与抽取字段的对应关系进行计算，最后计算表格的整体语义，度量该表格与所要抽取的内容有多大相关度。

Here's an example: You hear DAH DIT DIT which is a dash then dot then dot.

下面是一个例子：你听到瓦达赫抽取抽取这是一个破折号然后点然后点。

Since the decimation of discrete time signals is similar to the sampling of continuous signals, it is also studied in the thesis.

鉴于对离散信号的抽取和对连续信号的采样非常相似，本文还把研究范围拓展到了对离散信号的抽取问题。
