The following results are obtained:(1)a derivative formal context of an information system can be induced by the notion of nominal scale and the technique of plain scaling in formal concept analysis;(2)some core notions in rough set theory such as partition,upper and lower approximations,independence,dependence and reduct can be reinterpreted in derivative formal contexts.

Growler, lost at sea in February, 1944. Black at that depth turn, golden boy no more white bone to bone, turn hear who bore you weep hear him who made you deep there on ocean's floor turn as waters stir; turn, bone of man Cold as a planet is cold, beat of blood no more the salt sea's course along the bone jaw white stir, boy, stir motion without motion stir, and hear love come down. Down as you fell sidewise, stair to green stair without breath, down the tumble of ocean to find you, bone cold and new among the ships and men and fish askew.

在那深处漆黑一片翻转，不再是金童子白骨连白骨，翻转听听生你的人为你哭泣是他造就了你，你仔细听在大洋深深的底部随着海水的搅动翻转；翻转，男子汉的骨头如行星般寒冷寒冷，血不再脉动盐海的航向沿着白色颌骨搅动，小伙子，搅动没有动作的姿态搅动，并聆听爱降下来向下，当你倒向一侧，梯级到绿梯级没有呼吸，随着大洋的翻滚找到你，骨头寒冷而新鲜，在歪歪斜斜的船只丶人丶鱼之间。

The utility model is characterized in that a commonly used escalator which is formed by a plurality of active rundles and handrails is assembled on a vehicle, and the drive force of the escalator is suppplied by the vehicle through the mechanical transmission system; a mechanical transmission system is added in the vehicle and the mechanical transmission system mainly transmit the dynamic energy to the escalator carried on the vehicle, the rundles and the handrails can move in positive or opposite direction synchronously; a hydraulic power transmission system is added in the vehicle, and then the hydraulic power transmission system mainly transmit the dynamic energy to the escalator carried on the vehicle as well as related hydraulic power transmission devices or facilities; the whole vehicle-carrying escalator is supported by the supporting facilities, or the whole vehicle-carrying escalator moves upwards and downwards taking the axle direction which movably connects the lower end and the tail end of the vehicle as center.

其主要技术特征是：将主要由若干节活动梯级、扶手带等组成的现代所通常使用的自动扶梯安装在机动车上，并使自动扶梯的主动力部分由机动车通过机械传动系统供给；在机动车上增加机械传动系统，该机械传动系统主要向所载的自动扶梯传递动能，并使自动扶梯的梯级和扶手带能够同步正向或反向运动；在机动车上增加液压传动系统，该液压传动系统主要向车载自动扶梯的相关液压传动装置或设施传递动能，并在机动车的液压传动作用下，使支撑设施支撑整体车载自动扶梯，或使车载的自动扶梯以下端与机动车末端活动连接的轴向为中心整体升、降运动。
