本试验欲探讨种源之变异状况，并计算广义遗传率及遗传变方百分率，以了解遗传之特性；测验其生长性状之相关性，并利用线性回归，试图找出最适合台湾四湖海岸生长之种源及早期选拔之年龄；利用主成份因子分析做形态性状之综合评估，以了解种源之形态特性，并利用主成分因子分析和归群分析，了解种源间之空间分布及相互关系。

The mean generation interval of the flock is 5. 42 years of the current breeding scheme, and the ratio of input and output is 1∶11. 50, but the rate of mammitis will increase at the speed of 2%, at the same time, the number of daughters and sons of test bulls is not large enough for good accuracy for estimating test bull breeding value, so the breeding scheme in effect need to be improve.

D、在影响育种效益的诸因素中，单一的加大群体规模、育种群比例以及每年选留测验公牛数将在一定程度上提高育种效益和遗传进展，但随选留种子公牛数提高将降低育种效益和综合育种值遗传进展；在育种实践中应尽量扩大育种群规模和主动育种群比例。

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。
