Among them, 20 patients were candidates of valve replacement and 18 PDA and pericarditis had their blood samples taken before operation,and 1,2,24 and 48 hours after closure of thorax for measurement of concentrations of CK、CK-MB and TnT,together with ECG recording. Results Of the 60 patients, concentrations of cTnT before operation were normal; 2 hours after aortic unclamping, the correlation coefficient between cTnT and aortic clamping was r = 0.873( P＜0.01), the regression analysis showed Y = 0. 019X-0. 026. Of the 20 patients, ECG showed the myocardium was ischemic; CK、CK-MB and cTnT all rose significantly, reaching the peak after closure of thorax. Of the 18 patients, the ECG and cTnT before operation and after closure of thorax were normal; except 2 patients with pericarditis.

It is interpreted that the correlation structure of the allelic polymorphism data contains null correlations introduced by "closure" and the statistical distribution of the data is not normal because of its constant row sum,which resulted in great difficulties in analyzing the data with traditional multiple linear statistical methods such as principal component analysis,factor analysis,cluster analysis and canonical correlation analysis.

Objective To study the mechanism in which the personality, copying style influenced survival time by changing immunity function in the patients with gastric cancer Methods The Minnesota Multiphase Personality Inventory, coping style questionnaires and immunity function were measured in patients with gastric cancer on late stage, gastric cancer patients with longer survival time, and normal control Results Psychopathic deviate, social introversion subscale scores of MMPI in groupⅡ were significantly lower than that in the other two groups ( P 05) Statistical difference were found between groupⅠand groupⅡ in problem saving factor and help seeking factor of CSQ ( P 05) Natural killer cell level in groupⅡ was significantly higher than in groupⅠ( P 05) There was negative correlation between the NKC and depression, psychopathic deviate, paranoia, psychasthenia, schizophrenia subscale scores of MMPI, there was positive correlation between NKC and SP, coping type in patients with gastric cancer Conclusion The gastric cancer patients with longer survival time are more extroversive and have more mature coping styles Their NKC level is relatively higher The results may be advantageous to improve the prognosis of gastric cancer

3In the normal space tensile,after controling the influence of density, the variation ofmicrofibril angle had a decisive effect on L MOE and longitudinal tensile strength of D333A wood microtome section; the Correlation coefficient between microfibril angle and L MOE became significant at 0.05 level for D1123A wood microtome section; the Correlation coefficients were all unsignificant between microfibril angle and L MOE and between microfibril angle and longitu- dinal tensile strength to D1223A wood microtome section.

This thesis presents the preliminary study of the influence of sentence stress on prosodic features in Mandarin, and of the relationship between duration and pitch under different sentence stress levels. The results show that: The pitch is the most important factor which carries the sentence stress, with the increase of the sentence stress level, the peak of distribution contour of pitch moves towards high frequency area. In the case of"Stress"and"Light", two peaks are found in the distribution contour of duration, which means that the duration of some words are affected by sentence stress, but of others are not. The relationship between pitch and duration in"Normal","Stress"and"Light" are un-correlated, positive correlation and negative correlation respectively.

研究了汉语语句重音对音长和音高的影响、及音长和音高之间的相互关系，结果指出：（1）音高是汉语语句重音的基本表达手段，随着语句重音级别的提高，音高的统计分布曲线向高频方向推移；（2）在连续语流中的词被&重读&和&轻读&的情况下，音长分布出现双峰，表示它们的音长存在着受语句重音的影响和不受语句重音的影响两种情况；（3）词在&正常&、&重读&和&轻读&三种情况下，音高和音长的相互关系分别是：不相关、负相关和正相关。
