| 中文摘要: |
| 通过模拟进口大豆在海运中的环境，结合生物调查统计中被害指数的原理，引入指标热损伤平均级值，探讨进口大豆在不同的储运温度和含水量下发生热损伤的情况。结果表明：进口大豆的含水量和储运温度是热损伤发生的直接影响因素，在30、40、50、55℃下储藏28 d，含水量小于等于13%的大豆发生热损伤的进程较慢，试验样品的热损伤平均级值均未达到热损伤粒程度的级值，说明大豆含水量小于等于13%，温度低于55℃的条件下，短期储存中大豆发生热损伤的程度较低，进程较慢；破碎粒大豆比完整粒大豆容易发生热损伤，并且发生热损伤的程度也相对高；巴西大豆比美国和阿根廷大豆容易发生热损伤，且发生程度也相对较高。 |

| By simulating the environment of imported soybean in sea transportation，combining the principle of damage index in biological survey statistics and using the average level of heat-damage as index，the effects of storage temperature and moisture content of imported soybean on its heat-damage were studied. The results showed that the moisture content and storage temperature were the directly influencing factors for the heat-damage of imported soybean. After being stored at 30，40，50[KG-*8]℃and 55[KG-*8]℃ for 28 d, the heat-damage process of soybean with moisture content less than 13% was slow，and the average level of heat-damage of the test samples did not reach the level of the heat-damaged kernel. Under the conditions of moisture content below 13% and temperature lower than 55℃，the degree and process of heat-damage of soybean were low in short-term storage. The broken soybean was much easier to cause heat-damage than the complete soybean，and its heat-damage degree was higher. Heat-damage was more likely to occur in Brazil soybean than in the USA and Argentina soybeans，and the occurance degree was higher. |
