    摘要： In a side wall construction of a vehicle body, including an annular frame structure composed of a front pillar portion, a rear pillar portion, a roof side portion connecting upper ends of the front and rear pillar portions with one another, and a locker portion connecting lower ends of the front and rear pillar portions with one another, and a door adapted to selectively open or close the framed door opening, the door is longitudinally reinforced by a longitudinal reinforcement so that, when the front pillar portion is biased toward the rear pillar portion by a force longitudinal to the vehicle body, a larger part of the force is transmitted through the door than through the roof side portion.

    摘要： A method of terminating a gas phase polymerization of an olefin to be conducted subsequent to producing a polyolefin by feeding a gaseous olefin into a fluidized bed reactor to polymerize the gaseous olefin while holding solid particles containing a catalyst in a fluid state, said method comprising introducing a deactivator in the fluidized bed reactor through at least two deactivator introduction ports of the fluidized bed reactor so as to terminate the gas phase polymerization. The height of the fluidized bed is generally at least 3 m. The deactivator is preferably introduced through deactivator introduction ports disposed at heights Ha=-0.3 D to 0.3 D (a) and Hb=0.3 D to 2.0 D (b) (D is the inside diameter of the fluidized bed reactor (cm)). After the termination of the polymerization, the gas phase polymerization can directly be resumed. Formation of the product during the termination period can be minimized and the gas phase polymerization can rapidly be terminated even if the amount of the deactivator is small. Also, an apparatus which is suitable for the above termination and resumption of gas phase polymerization is provided.

    摘要翻译： 一种终止在生产聚烯烃之后进行的烯烃的气相聚合的方法，该方法包括将含有催化剂的固体颗粒保持在流体状态的同时将气态烯烃加入到流化床反应器中以聚合气态烯烃，所述方法包括引入 通过流化床反应器的至少两个失活剂引入口在流化床反应器中的钝化剂，以终止气相聚合。 流化床的高度通常至少为3米。 失活剂优选通过设置在高度Ha = -0.3D至0.3D（a）和Hb = 0.3D至2.0D（b）（D为流化床反应器的内径（cm））的失活剂引入口引入。 聚合终止后，可以直接恢复气相聚合。 终止期间产物的形成可以最小化，即使减活剂的量小，气相聚合也可以迅速终止。 另外，提供了适合上述终止和恢复气相聚合的装置。
