果蝇的热暴露试验一般是将果蝇置于人工气候箱（人工气候箱预先升温至所需的热暴露温度）中，随着时间的延长，实时观察热暴露果蝇的死亡率和存活率。由于果蝇对温度的热敏性很高，温度是影响果蝇耐热性的主要因素，所以果蝇的热暴露实验对人工气候箱温度精密度和均匀性的要求高。传统人工气候箱的温度调节系统运行时冷热风进出、光源蓄热等因素造成箱体的局部温度降低或升高，出现人工气候箱的局部温度不均匀、精密度较差等问题，对热暴露果蝇的死亡率和存活率影响极大，平行重复性差，实验数据的准确性不高，极大影响了果蝇热暴露试验的最终结果。 In the heat exposure test of fruit flies, the fruit flies are generally placed in an artificial climate box (the artificial climate box is pre-heated to the required heat exposure temperature), and the mortality and survival rate of the heat-exposed fruit flies are observed in real time as time goes by. . Due to the high heat sensitivity of fruit flies to temperature, temperature is the main factor affecting the heat resistance of fruit flies, so the heat exposure experiment of fruit flies has high requirements on the temperature precision and uniformity of the artificial climate chamber. The temperature adjustment system of the traditional artificial climate box runs in and out of the cold and hot air, the heat storage of the light source and other factors cause the local temperature of the box to drop or rise, and there are problems such as uneven local temperature and poor precision of the artificial climate box. The mortality and survival rate of exposed fruit flies have a great impact, the parallel repeatability is poor, and the accuracy of experimental data is not high, which greatly affects the final results of the fruit fly heat exposure test.
