| 摘 要： | 根据脾循环的特点，提出了脾循环的流动模型，应用该模型，从理论上探讨了增加脾动脉流量和升高脾静脉压力对脾脏储存血液和红细胞的影响。分析表明：当脾动脉流量增加或脾静脉压力升高时，脾的体积增大、脾内血球比积增加、储存的红细胞增多。为了验证理论分析的正确性，对离体的狗脾脏进行了增加脾动脉流量和升高脾静脉压力的实验研究，实验结果同理论分析相一致。

| Abstract: | A flow model for splenic circulation system was proposed, according to the knowledge of its circulatory characteristics. The effect of increments in splenic arterial flow(SAF) and splenic venous pressure(SVP) on splenic blood and red cell accumulation were analyzed by using the model. The results showed that an increase in SAF or SVP caused a rise in splenic size and hematocrit, concomitantly a greater accumulation of the splenic raf cell. These results were justified by the experimental study of dog spleen in vitro |
