摘要
将１２只家兔的肠系膜上静脉（ＳＭＶ）随机分为两组：Ⅰ（正常组３７±０．５℃）和Ⅱ（低温组２０±０．５℃）。通过充压试验结果表明：兔ＳＭＶ环箍应力－应变关系为指数函数关系，温度对兔ＳＭＶ材料常数有明显影响，材料常数ｘ１组间比较有显著性差异（Ｐ＜０．０５），材料常数ｘ２组间比较差异无显著性。认为ｘ１是温度敏感因子。
12 superior mesenteric veins (SMV) of rabbits were divided into two groups for experiment of inflation pressure: Ⅰ (the normal temperature group, 37 ± 0. 5℃ )and Ⅱ (the group on low temperature , 20 ±0. 5℃ ). The results showed that the relationship of circumferential stress-strain of SMV could be expressed withexponential equations. Constant X1 was effected by temperature. The difference between the two groups in material constant X1 was statistically significant (P<0. 05), but these was no significant difference (P>0. 05) betweenthe two groups in material constant X,. Therefore it is believed that X, is the factor concerning temperature sensitlvity.
