讨论了轴对称非均匀磁场对带电粒子的作用，分析了"磁约束"对防垢、除垢的微观机理，指出满足磁约束理论的轴对称非均匀磁场的防垢，除垢效果好的原因，正是由于在这种磁场中，带电粒子的运动被约束在一定磁面上的某一磁感应线附近做以该磁感应线为中心的螺旋运动，且正、负离子的回旋方向相反，从而形成内部相互作用较弱的大分子簇团不易吸附在管壁上，达到防垢目的；磁化水的渗透压较大，可起到除垢效果。

Tracing the journey of their works from marginality to centerpiece in literary history, this paper holds that ideology, poetics and patron play a vital role in the way to canon, which is a universal law applicable to different national literatures.

本文旨在考察他们的作品从边缘走向中心的过程中，意识形态、主流诗学和赞助人所起的作用，以管窥文学经典化形成中的共性。

Influenced by tectonic movement, there were no sediments in the area from Oligocene to Miocene. Appearance of marlite in the Pliocene, especially in Yaqueling region, proved localized depositing environment forming, for which there had only few amount of terrigenous matters to supply. Sedimentary facies association of alluvial fan, fan delta and inland lake appeared at the early and middle stage of lower Pleistocene, and association of fan delta and inland lake appeared at the later stage of lower Pleistocene and the early stage of middle Pleistocene. Net-veined laterite appeared at the top of lacustrine deposit, which reflected pedogenesis taking place after the end of deposition. Such evolution history proves that there had no lager river system traversing this area before the early stage of middle Pleistocene.

对于江汉盆地西缘宜昌地区来说，其沉积及古地理演化表现为：早白垩世为受天阳坪断裂控制的内陆湖泊沉积环境，沉积中心在天阳坪断裂的北侧，此时几乎不存在来自黄陵地区的水系；晚白垩世同样为受断裂控制的内陆湖盆环境，但湖盆面积扩大、断裂活动减弱，且后期出现成化湖相沉积；第三纪早期盆地由断陷盆地转变为坳陷盆地，同时石膏的出现代表了局限咸化湖盆的存在；渐新世—中新世，受构造影响，缺失该时期的沉积；上新世时在鸦鹊岭一带出现的泥灰岩沉积反映了陆源物质供应不足的局限沉积环境的存在；早更新世早中期为冲积扇—扇三角洲—内陆湖泊沉积，早更新世晚期—中更新世早期为扇三角洲—湖相沉积，后期出现沉积结束以后的网纹红土化作用。

WOLFSBURG, Germany / LOS ANGELES, Calif.- In a world premiere at the Los Angeles Auto Show, Volkswagen presents the GX3 – a completely new type of motorcycle. The GX3 was conceived by the Moonraker team and VW's Design Center in California, exclusively with the U.S. in mind, to bring an exciting idea to a fully functioning concept.

WOLFSBURG，德国/洛杉矶，加利福尼亚Moonraker 队设想了GX3，VW 设计中心在加利福尼亚，专门与美国在心里，给一个完全起作用的概念带来一种令人激动的想法。

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。
