| During the irradiation period, the temperature inside the test chamber should rise at a rate close to linear and remain at the set temperature control value (typical settings are+55 ℃ and 40 ℃). During the shutdown phase, the temperature inside the test chamber should decrease at a rate close to linear to the set temperature control value (typical setting value is+25 ℃) and maintain temperature stability. The relationship between temperature, irradiation, and time during different experimental procedures is shown in Figure 2. | ||||||||||||||||||||||||||||||
