Double—blind, randomized, placebo—controlled clinical trail on Chronic Congestive Heart Failure with Shengmai capsule treatmentResult:5.1 The left room shoots the blood score EF value:EF value three hour point total to distribute the characteristic obeys positive the normal distributes, proceeding the independent sample t examination: diagnosing moment hour point an EF value variety of placebo group and treatment group have no to show the difference of obvious; 12 weeks with 24 week hour point, an EF value variety of placebo group and treatment group also have no to show the difference of obvious.

两组EF值再分别作自身前后对照——配对样本t检验：安慰剂组在就诊时分别和试验12周、24周进行对照，发现其自身前后的EF值并无显著性差异(P＞0.05)；治疗组也作同样对照，虽然EF值在三个时点的变化均无显著性差异(＞0.05)。5.2 NYHA心功能分级安慰剂组和治疗组治疗前后的非参数检验——Wilcoxon检验：两组治疗前后心功能分级对照无显著性差异(＞0.05)。

The quality change between the ungrafted film and grafted film was analyzed. The surface configuration and constitute of the film were characterized by SEM and IR, and the contact angle was measured.

The microstructure of the magnesium alloy before and after ECAP were examined by means of OM and TEM. The hardness of the as-extruded and unextruded Mg-6Zn-1Gd-0.6Zr magnesium alloy was examined by vickers hardness tester. The rolling of the crystal plane in the process of ECAP was analyzed by X-ray diffraction.

采用光学显微镜和透射电子显微镜分析了试样ECAP变形前后的显微组织变化，采用显维硬度计对Mg-6Zn-1Gd-0.6Zr合金ECAP变形前后进行了硬度测试，采用X-射线分析法分析了ECAP变形过程中晶面的转动。

The major findings are:⑴During the intelligence test for the three groups of students, for half of the students or most of the students their scores on the all-including scale, the language scale and the performance scale all increased to various degrees;⑵From the analysis of the relationship between intelligence and reaction time, it is found that the result of this study confirms the existing views that there is a negative correlation between intelligence and reaction time, and the negative correlation is more evident when it is choice reaction time;⑶Different motor skills have different influences upon children with lower intelligence. Though the difference is not large, the average increasing percentages in the sample T tests for the three groups before and after the experiment show that the effect of open motor skill is the best, that of the synthetic motor skill or the open-closed is the better, and that there isn't a marked change in the closed motor skill trainees;⑷While analyzing the result of the experiment, it is found that the scores on the performance scale are higher than the scores on the language scale, especially in the open motor skill group, which tells us that the intelligence improving effect of physical training is realized to a greater extent through increasing their performance abililty.

研究结果显示：⑴相对于实验前测试结果，三个实验组学生的智力水平在实验后测试中不论是在全量表得分还是在语言量表、操作量表得分方面均得到了不同程度的提高；⑵从智力与反应时的相关分析可看出，本研究结果进一步验证了前人观点，即智力与反应时有显著的负相关，特别是与选择反应时有很强的负相关性；⑶不同运动技能对智力落后学生智力影响不同，虽然实验后各组间没有显著性差异，但经各组实验前后配对样本T检验及实验前后各项分数均值提高百分率可看出，开放式运动技能组实验效果最好，综合运动技能组次之，闭锁式运动技能组实验前后在智力测验量表得分上无显著性变化；⑷各组实验前后的操作量表分比言语量表分提高幅度更大，开放式运动技能组表现得尤其显著，这表明了体育活动对改善智力落后学生的智力水平，很大程度上是通过提高他们的操作能力来实现的。
