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

The results show that more modalities can be excited from asymmetric system and that there is little difference between the power flow spectra of rigid raft system and flexible raft system in middle and low bands of frequency, but there is considerable difference at high frequency.

研究结果表明，非对称系统能激励出更多的模态；在中低频段弹性浮筏系统和刚性浮筏系统的功率谱没有很大的区别，但是在高频段差别则很明显，浮筏的弹性模态起着主要作用；减小隔振器的刚度并适当增加隔振器阻尼不仅可以降低传递到基础的功率谱，同时还可以抑制共振减小冲击。

The results show that amplitude of defect signal is adversely affected by lift-off variations,but phase difference between defect signal and lift-off loci is almost unchangeable.After analyzing the characteristics of the phase difference with the chang of frequency,a conclusion that defect signal is approximately vertical to lift-off noise at a well-selected frequency is obtained.

Between the Chinese and American culture difference has accomplished the China and America classroom instruction difference, but this kind of difference comes from in the Chinese and American education idea and the educational system difference, the China elementary education attention knowledge accumulation and instills into, the attention trains the student to ask the same thought and the attention trains the student to the knowledge itself grasping, but US pays great attention to actually trains the student to carry on the solution actual problem using the knowledge ability, the attention trains the student to the knowledge innovation and the development, also the attention raises the student criticalness thought and the divergent thought.

中美文化之间的差异造就了中美课堂教学的差异，而这种差异来自于中美教育理念和教育制度上的不同，中国基础教育注重知识的积累和灌输，注重培养学生的求同思维和注重培养学生对知识本身的掌握，而美国却注重培养学生运用知识进行解决实际问题的能力，注重培养学生对知识的创新和拓展，且注重培养学生批判性思维和发散性思维。

The difference schema of the initial boundary value problem was converted to the step-by-step form,which was similar to the difference schema of the initial value problem.It is concluded that the difference schema satisfying the Von Neumann condition is a stable schema,and that,under the consistency condition,such stable schema is convergent.Moreover,with error estimate expression for the difference approximation to the classical solution,the linearity condition is unnecessary.

引入反投影算子将发展方程初边值问题的差分格式转化为与初值问题差分格式类似的逐步推进的形式，从而得出：满足Von Neumann条件的差分格式是稳定的格式；在相容条件下，差分格式若稳定(或满足VonNeumann条件)则格式收敛，且对古典解的差分逼近有误差估计式，不再需要线性的条件。

Goodbye Alice in Wonderland Jewel It's four in the afternoon I'm on a flight leaving L.A. Trying to think about my life My youth scattered along the highway Hotel rooms and headlines I've made a living with a song Just a guitar as my companion Wanting desperately to belong Fame is filled with spoiled children They grow fat on fantasy I guess that's why I'm leaving I crave reality So goodbye Alice in Wonderland Goodbye yellow brick road There is a difference between dreaming and pretending I did not find paradise It was only a reflection of my lonely mind searching For what was missing in my life I'm embarassed to say the rest is a rock and roll cliche I hit the bottom when I reached the top I never knew it was you who was breaking my heart I thought you had to love me You did not Yes a heart can hallucinate If it's completely starved for love Can even make monsters seem like Angels from above You forged my love like a weapon And turned it against me like a knife You broke my last heartstring But you opened up my eyes So goodbye Alice in Wonderland Goodbye yellow brick road There is a difference between dreaming and pretending That was not love in your eyes It was only a reflection of my lonely mind wanting what was missing in my life And growing up is not the absence of dreaming It's being able to understand the difference between the ones you can hold And the ones that you've been sold Dreaming is a good thing cause it brings new things to life Pretending is an ending that perpetuates a lie Forgetting what you are Seeing for what you've been told Well, truth is stranger than fiction And this is my chance to get it right Life is much better without all of your pretty lies So Goodbye Alice in Wonderland You can keep your yellow brick road there is a difference between dreaming and pretending There's not tears in my eyes It was only a reflection of my lonely mind searching It was only a reflection of my lonely mind finding I find what's missing in my life
