Their waiting in drunken illusions is the means of survival for modern man designated by O'Neill who is deeply influenced by the Nietzschen philosophy and impending World War II. Waiting for Godot exposes the absurd existence of modern man as well as Beckett's uncertainty of the world and concerns about human prospects under the impact of World War II and absurdist theories based on existentialism.

然而，不同的社会、文化背景又使得三剧的"等待"主题具有各自不同的特征：工会成员对老左的等待具有现实性，表现了他们对一位无产阶级领导人的忠贞；房客对希基的等待既具有现实性，又具有荒诞性，在酒精和白日梦中的等待是奥尼尔为处于现代社会绝境中的人们指出的生存之路；流浪汉的等待反映出现代人存在的荒诞性，以及贝克特对世界的怀疑和对人类前景的忧虑。

The left ventricular internal dimension at end diastole, interventricular septal thickness at end diastole and left ventricular posterior wall thickness at end diastole were measured in the parastemal long axis view by transthoracic two-dimensional echocardiography, and to calculate left ventricular ejection fraction with Teichholtz formula and left ventricular mass with modified Devereux formula, left ventricular mass index=LVM/body surface area. From the apical four chamber and two chamber view, the basical segment and middle segment of interventricular septal, left ventricular lateral wall, anterior wall and inferior wall were obtained by tissue Doppler imaging, Regional left ventricular relaxation asynchrony index was calculated.

As an extension, we also obtain some sufficient and necessary conditions under which M_c is left Fredholm and left Weyl for some left invertible operator C, respectively.In chapter 2, the sufficient and necessary condition under which the difference of two idempotent operators on infinite dimensional Hilbert spaces is Fredholm (in-vertible) is discussed. In addition, some equivalent conditions under which products and differences of projections in a C~*-algebra are Moore-Penrose invert-ible are obtained.

The first chapter, main instead " duo-ring " condition of " every maximal left ideal is GW-ideal " condition,study strongly regularities of GP-V-ring on this condition.lt is shown that (1) R is strongly regular iff R is left GP-V-ring whose maximal left ideals are GW-ideal.(2)R is strongly regular iff R is left GP-V-ring whose maximal right ideals are GW-ideal. The second chapter, generalize some results of GP-V-ring to GP-V-ring, discuss regularity of GP-V-ring.It is shown that (1) R is left self-injective regular with non-zero socle iff R is left GP-V -ring with Soc = Soc and R contains an injective maximal left ideal.(2)R is regular ring and every maximal essential left ideal is ideal iff R is left GP-injective left GP-V -ring and every maximal essential left ideal is ideal.

第一章主要将"duo-环"条件替换成"每一极大左理想是GW-理想"条件，研究在此条件下，GP-V-环的强正则性，证明了：(1)R是强正则环当且仅当R是左GP-V-环且R的每一极大左理想是广义弱理想；(2)R是强正则环当且仅当R是左GP-V-环且R的每一极大右理想是广义弱理想，第二章，主要将GP-V-环上一些结果推广到GP-V′-环上，讨论GP-V′-环的正则性，证明了：(1)R是左自内射正则环且Soc≠0当且仅当R是包含内射极大左理想的GP-V′-环，且Soc=Soc；(2)R是正则环且每一极大本质左理想是理想当且仅当R是左GP-内射的左GP-V′-环且每一极大本质左理想是理想。

Methods The left ventricular diastolic function,the blood speed during quick filling phaseof left ventricular of the mitral valve orifice,the peak value of the late phase of left ventricular diastolic pariod;E/A ratio,the time for isovolumetric relaxation phase of left ventricular,the reducel time of peak E,and the distance between peak E of mitral valve and intervertricular septum of left ventricular were measured respectively.

摘要］ 目的应用彩色多普勒超声心动图测定冠心病左室舒张功能，临床提供可靠的诊断及治疗依据方法分别测定冠心病组及对照组的左室舒张功能：二尖瓣口左室快速充盈峰值血流速度即E峰；左室舒张晚期峰值速度即A峰；E/A值，左室等容舒张时间，E峰减速时间，二尖瓣叶E峰与室间隔左室面的距离。

Impersonally the happening of the movement is because of lack of experience in construction and acknowledge of the speed , phase, and rule of the socialist construction.

大跃进"运动的发生，从客观上讲，是由于我国缺乏社会主义建设的经验，对社会主义建设的阶段、速度、规律认识不足；从主观上讲，是由于最高决策层，主要是作为领袖的毛泽东的错误决策造成的；从精神因素讲，由于"左的急躁冒进思想作崇，起了导向作用，而在这种错误背景下形成的歧变、偏误的群众心理，对大跃进运动起到了一定程度的推波助澜作用。

"Right now medical treatment exists for about 500 diseases and genetic disorders, but thanks to the human genome project, before long, new drugs will be aailable for thousands of other diseases," Dr. Romaine said."We need a new way of mass-producing protein-based drugs, which is economical, safe, and fast. We beliee mushrooms are going to be the platform of the future."

"现在医疗手段仅能治疗500个左的疾病和基因错乱，但是由于人类的基因组工程，不久以后，新的药物将能对另外的上千种疾病有效"，Romaine教授说，"我们需要一种新的方式去大量生产以蛋白质为基础的药物，它是经济的，安全的，快速的的，我们相信蘑菇将成为未来的这样一个平台"。

There was a good correlation between Ptw,AVCtw,MVOtw,PTV,PUV,UntwR and age.2.Assessment of left ventricular twisting and untwisting of DCM patients19 DCM patients(range 18-80 yr,mean age 50.52±17.52 yr,2 females) and 21 age- and sex-matched normal controls(range18-80 yr,mean age 49.05±16.94 yr,5 females) were enrolled into this study.Then DCM patients were divided into two groups:E/A＜2 group and E/A＞2 group.The routine echo showed the left ventricle dilated and EF decreased.The results show that LV rotation degree, rotation velocity at baseline and apex were irregular changeable with the cardiac cycle;the rotation direction was clockwise at the base and counterclockwise at the apex,and are combined to yield a systolic counterclockwise twisting as seen from the apex,but the rotation at the basal and apex were the same direction in some patients.

扩心病患者左室扭转及解旋特征的研究选择扩张型心肌病(Dilated Cardiomyopathy，DCM)组患者19例(男性17例，女性2例，年龄18～82岁，平均50.52±17.52岁)，健康体检者21例(男性16例，女性5例，年龄18～80岁，平均49.05±16.94岁)作为对照组，扩心病患者按照E/A分为E/A＜2、E/A＞2两个亚组，结果显示：常规超声显示DCM组LVDd值增大，EF值减小；DCM患者左室心底部与心尖部心肌旋转角度、旋转速度随心动周期变化曲线明显紊乱；与正常组比较，DCM患者左室整体扭转角度和速度分别为(6.49±1.82)°、(67.84±15.60)°/s，较正常人显著减低P＜0.01左室舒张末及收缩末扭转角度DCM患者较正常人显著减低(P＜0.01，左室舒张末及收缩末时间在DCM-E/A＞2组较正常人及DCM-E/A＜2组显著缩短P＜0.01DCM患者左室解旋速度较正常人亦显著减低(P＜0.01，左室功能轻中度减低(DCM-E/A＜2)患者解旋率[(0.29±0.07)%]较正常人[(0.42±0.11)%]明显减低，但当左室功能重度减低(DCM-E/A＞2)时左室解旋率[(0.63±0.35)%]较正常人反而增加；左室整体扭转角度、舒张末扭转角度、收缩末扭转角度、解旋与左室射血分数未见明显相关性。3。

Ever so, this kind of exploration has stablished the solid foundation for china"s modernization, have played and lays foundation on function for the settlement of china"s rural, agricultural, peasant"s problem, Its position is pioneering.Deng ciao-ping is in the new period for reform and opening up to the lutside world. He suggests reform and opening up the outside world as theAbstractmotive force of development, and reform the factor of fettering productivity development in the old system, make a reservation and solve the basic point of china"s rural problem again. He emphasize that liberates and develop rural productivity again and point out that the rich peasant is a key of solving the problem.
