摘　　要：以虚拟仪器构建了数据采集处理系统 ,对典型土壤动物黄鼠的生物柔性体表进行了在体减阻行为测试研究 ,结果表明对于同一个黄鼠 ,在体试样的滑动阻力明显比离体的低 ,其减阻率为 16 %～ 2 7% ;在相同压力作用下 ,黄鼠在体试样的触土面积比离体的大 ,说明活鼠的肌肉可对外力的激励做出反应 ,能适当调节触土面积使身体受力均匀并减少阻力 ;与钢板试样的对比试验结果表明 ,黄鼠在体试样具有优良的自清洁功能。The behavior of soil sliding resistance reduction of a flexible body surface of a yellow mouse (microtus manderinns) living body was investigated based on a virtual instrument data logging and processing system. The soil sliding resistances of a living body, dead body, and the fur of a mouse were measured and compared with that of steel sample. It is found that the resistance of living body is lower than that of the dead body for the same yellow mouse. The reduction ratio ranges between 16% - 27% under the test condition. The living body of a mouse can adjust the actual soil contact area by the reflection of the mouse's muscles to the external pressure to disperse the stress and reduce the resistance. The repeated tests show that the living body of a mouse had a remarkable function of self-cleaning.
