1、自上料搅拌车五次开关车门
1. Open and close the door five times from the charging mixer truck
经过编薄弱的理科知识分析，此种方法降温，是为了将车外凉爽的空气换入车内，而编测试的期间，车一直暴漏于阳光的暴晒中，车体被持续加温，空气替换的效果并不明显，车内温度在开关车门之后，并没有下降反而上升。而随后拍摄过程中，一直在开启车门状态，此时车内外的空气在持续流通交换中，所以经过两分钟左右的空气交换，车内的空气已经完成了部分替换，所以车内温度才会随之下降。
According to the analysis of weak science knowledge, this method of cooling is to change the cool air outside the car into the car. During the test, the car has been exposed to the sun, and the car body has been continuously heated. The effect of air replacement is not obvious. The temperature inside the car has not decreased but increased after opening and closing the door. During the subsequent shooting, the door was always opened, and the air inside and outside the car was continuously circulating and exchanging. Therefore, after about two minutes of air exchange, the air inside the car had been partially replaced, so the temperature inside the car would decrease accordingly.
体感：在经历过六次开关车门之后，车内温度虽然没有下降，但是已经将车内的空气进行了替换，所以体感很热，但不闷。随后在车内温度降为39.3度之后，再次进入车内，明显感觉气温下降。
Body feeling: After six times of door opening and closing, the temperature in the car has not decreased, but the air in the car has been replaced, so the body feeling is very hot, but not stuffy. Then, after the temperature in the car dropped to 39.3 degrees, enter the car again and feel the temperature drop obviously.
2、自上料搅拌车开窗兜风
2. Open the window from the feeding mixer
温度经历40.1度、41.6度之后，终于在进入树荫区域降回39.4度。
After 40.1 ℃ and 41.6 ℃, the temperature finally dropped to 39.4 ℃ in the shade area.
在兜风过程中，由于车外温度与车内温度相差不大，温度并没有下降，而在行驶中由于发动机的启动等原因造成了车内的温度进一步提升，之后进入树荫下，周边空气没有那么燥热的时候，车内气温才开始下降。
During the ride, the temperature did not drop due to the small difference between the temperature outside the car and the temperature inside the car. However, the temperature inside the car was further increased due to engine startup and other reasons during the drive. Then, the temperature inside the car began to drop when the surrounding air was not so hot and dry under the shade of trees.
体感：兜风过程中，虽然温度很高，同时阳光下很晒，所以依然感觉很热，但是由于有空气流动形成风，所以体表感觉比较舒适。
Body feeling: Although the temperature is very high and the sun is very hot during the ride, I still feel very hot, but I feel comfortable on the body surface due to the air flow.
