翻译：由于缺少试验条件头车阻力减少无法验证虽然目前数值方法可以匹配试验结果但经过思考过后这句话说得太绝对还是需要一定的试验才能支撑。结合审稿人提出的问题10本文将移除阻力部分重点描写防雪效果。

Due to the lack of test conditions, the reduction of the lead car's resistance cannot be verified. Although current numerical methods can match the test results, after careful consideration, this statement is too absolute and still requires some testing to support it. In conjunction with question 10 raised by the reviewer, this article will remove the resistance section and focus on describing the snow protection effect.
