Examination shows that the heart of andrias davidianus have three chamers - two atria and one ventride, the atria on the left of midline, the ventricle on the right of midline, and the atria are divided into two cavities by septum interatriale. there are four valvula semilunaris in conus arteriosus, but no spiral valve in conus arteriosus. the coronary artery is made by arterica carotis externa branches
研究結果表明，中國大鯢循環系統解剖學特點為： 1 .心臟：心房心室為左右排列，兩心房前後排列，共有4對動脈弓，其中第二、三對動脈弓匯合成一條背主動脈；動脈圓錐基部與心室相接處有4個瓣膜，動脈圓錐內沒有螺旋瓣，動脈圓錐與腹側主動脈干之間有3個半月瓣；房間隔有穿孔；冠狀動脈由頸外動脈的分支匯合而成。The dynamic response of cylindrical shells and conical shells under radial non - uniform impulsive loading has an important application in the filed of military and civil engineering. in this dissertation, the problem of transient response of the cylindrical shell under longitudinal line - loading and that of the conical shell under cosinoidal impulsive loading are studied, and some useful conclusions that have important significances in both theoretic studies and engineering applications are obtained
圓柱殼和圓錐殼在側向沖擊載荷作用下的動力響應具有重要的軍事和民用工程背景，本文對縱向線載荷作用下的圓柱殼瞬態響應問題和餘弦沖擊載荷作用下的圓錐殼瞬態響應問題進行了研究，取得了一些具有重要理論意義和實用價值的研究成果。
