摘　　要：HBDS型二代机下探角度 ,兼顾了货车和客车的探测 ,因车辆自身状况、货物装载以及线路水平等因素的影响 ,导致一些货车滚动轴承热轴不能准确判别或预报。The bottom detection angle of the HBDS type detector of the second generation gives consideration to detection on both the freight car and the passenger car, due to effect of such factors as the car conditions, goods loading and track level, the hot box of some rolling bearings on freight cars cannot be correctly determined or forecasted. It is put forward in the paper that the correctness of forecast can be improved by improving the aiming point and lowering some forecast standards.
