The results were analyzed with the statistical software package spss10.0.results ①between two groups,there was no significant difference about the affection of age,sex and the destribution and location of aneurism on prognosis outcome(p＜0.05).however,the grading of hunt hess and fisher in group a(gos＞3) showed significantly lower than in group b(gos≤3),（p＜0.001）;② there was no significant difference in the frequency of heart rate, st elevation, st depression,t wave inversion,u wave inversion and ventricular arrhythmia(p＞0.05).the frequency of abnormal q wave, supraventricular arrhythmia and the ecg scores in group a showed significantly lower than in group b （p＜0.05,p＜0.001）;③the ecg scores was the most powerful multivariate risk stratified(ecg ≥5 vs ecg＜5; p=0.002,or=0.010,95%ci 0.001~0.173).conclusion the ecg score, a new and simple method of semi quantification, was a powerful risk predictor for patients with sah.

应用spss10.0 统计包分析结果。结果①在年龄、性别、动脉瘤生长部位影响动脉瘤性sah预后方面，两组病例无明显差异（p＞0.05）。而按sah后hunt hess分级和fisher分级，gos＞3病例的分级要明显低于gos≤3的病例的分级（p＜0.01）；②两组在心率、st段抬高、st段压低、t波倒置、u波倒置、室性心律失常出现的频率无明显差异（p＞0.05）；在异常q波和室上性心律失常出现频率及心电图评分方面，gos＞3的组别明显低于对照组（p＜0.05，p＜0.001）；③心电图评分是sah患者预后最显著影响的变量（p=0.002，or=0.010，95%的可信区间0.001~0.173）。结论心电图评分作为一种新型、简便的半定量方法，能有效的预测蛛网膜下腔出血病人的预后。关键词：心电图；预后；评分；蛛网膜下腔出血

This paper analyzes from the theories and engineering examples to review rationality of the different torsion effect indexes, such as relative torsion effectθr/u, shear force ratioλbetween torsion and translation, eccentric angle of torsion.

本文从理论分析和算例考证两个方面，考查相对扭转效应θr／u、扭转与平动引起的剪力比值λ和楼层偏心扭转角α等不同扭转效应指标的合理性，研究不同指标的影响因素及它们之间的内在联系。

The mechanism is composed of two ball screws, U-type linear rails, linear bearings and flexible couplings. The permanent magnetic direct current motors are used as actuators. The rotary encoder is used to measure the angular position of the DC motor. The digital controller is implemented on the personal computer and a motion control card (EPCIO-6000). The objective of this thesis is to realize precise positioning control using a real-time motion control system on an X-Y table.

机械结构包括有滚珠导螺杆、U型线性滑轨组、线性轴承及可挠性连轴器等；致动器是采用永磁式直流马达(permanent magnetic direct current motor)；感测器是使用光学式旋转型编码器来量测马达旋转的角度；控制器则是以个人电脑为控制核心，搭配运动控制轴卡(EPCIO-6000)所组成。
