You must pay attention to the working temperature of the machine. 你們必須注意機器的工作溫度。
The maximum operating temperature is directly related to the heat treatment process used in manufacturing components. 最高工作溫度與製造元件所用的熱處理工藝直接有關。
Though the heat produced convection and further blurring, it was the only way to keep the camera at a reasonable operating temperature for an extended period of time. 儘管熱能產生對流並且讓影像更加模糊，但只有這樣才能讓相機在長期曝光拍攝中有一個合適的操作溫度。
