| 研究苹果在0.5～3.5kg的静载及12～84h作用时间内的接触面积和直径的变化规律，用四元件Bergers模型和回归分析方法描述其蠕变特性并求得蠕变参数。通过对接触面直径与蠕变参数关系的分析，说明用延迟时间评价和预测静载损伤的可能性。 |

| Abstract: |
| The varying law of apple contaeting area and diameter under the load of
0.5～3.5 kg held constant for 12～84 hours was investigated.Peristaltic charaeteristies
and parameters were deseribed by using four elements Burgers and regression analysis.
Through the analysis of there lation ship between the contaeting area diameter and the
peristaltic parameter,the possibilities to evaluate and foreeast static load,by using delay
time,were obtained. |
