初生仔猪肠管数据的相关回归分析

取32例初生仔猪,分离其小肠、大肠,并将血管用乳胶灌注,然后测量其体长、小肠、大肠长度及口径以及分布到小肠、大肠上的动脉分枝数目。利用计算机处理得出:小肠长度与直径之间,体长与小肠长度之间,体长与小肠直径之间,小肠的1级分枝与终末枝之间,小肠长度与1级分枝之间,小肠长度与终末分枝之间有相关性;但是小肠直径与动脉分枝间无相关性。大肠长度与直径之间,体长与大肠长度之间,体长与大肠直径之间、大肠的长度与终末枝之间、大肠的直径与终末枝之间有相关性。

THE RELATIONAL REGRESSION ANALYSIS OF THE INTESTINAL DATA OF NEWBORN PIGLETS

32 newborn piglets were used.Their small and large intestines were separated.Their ab-dominal aorta was injected by the coloured latex.Then the body length and the length,cali-bre and numbers of arteric branches of the small and large intestines were measured.The re-sults were treated by means of a computer.There are correlations between the length and cal-ibre of small intestine,the lengths of body and small intestine,the body length and the cali-bre of small intestine,the primary and the terminal arteric branches of small intestine,thelength of small intestine and the primary arteric branches,the length of small intestine andthe terminal arteric branches,but there is no relation between the calibre and the number ofarteric branches of small intestine.There are correlations between the length and the calibreof large intestine,the lengths of body and large intestine,the length of body and the calibreof large intestine,the length and the terminal branches of large intestine,the calibre and theterminal branches of large intestine.
