自重系数-
为了满足货物运输的需要，某厂最新研制了目前国内载重量最大、承载面最长且在大吨位凹底车中自重系数最小的370t凹底车。
In order to meet the need of freight , a factory developed 370t center-depressed flatcar which is the biggest domestic load-carrying capacity , the maximum load bearing surfaces and the smallest dead weight coefficient in the great tonnage center-depressed flatcar .
