A wind- and motor-powered land vehicle with a fore-and-aft longitudinal axis comprising a body supported by wheels, at least one of said wheels fixed to rotate in a plane parallel to the fore-and-aft axis of said vehicle, an airfoil system comprised of two vertically extending airfoils rigidly mounted on said body in an arrangement having bilateral symmetry about a vertical plane through said fore-and-aft axis, said airfoil system providing a forward propelling force of said vehicle when the airfoil system is subjected to certain cross wind conditions, and self-contained motor propulsion means on said vehicle for providing acceleration from a stationary position and for propelling the vehicle either independently or in combination with propelling forces generated by wind action on said airfoil system, each airfoil having a plurality of airfoil sections telescopically fitted together, the lower airfoil section being rigidly mounted in fixed relationship to said body, said airfoil system including a retracting mechanism for lowering upper airfoil sections of said airfoil system when desired and for subsequently extending said airfoil system, said retracting mechanism including a plurality of linkages interconnecting said sections and an actuator means operatively connected between said body and to said linkages for lowering and extending each airfoil, and an intermediate airfoil extending between the upper sections of each of said airfoils so as to provide an inverted U-shaped airfoil.

风力和电动机驱动的陆地车辆与前列和尾部长轴组成的一个机构的支持，车轮，至少有一说，车轮固定在一个旋转平面平行的前列和前后轴的说，车辆，翼型系统组成的两个垂直扩展翼型硬性安装在说，机构在安排后，双边对称约一垂直面说，通过国内外和前后轴，表示翼型系统提供了一个向前推进的力量说，车辆时，翼型系统是受到某些横风条件下，和自我载电机推进的手段就表示，车辆提供加速从一个固定的立场和为推进车辆单独或结合，与推进力量所产生的风的行动表示翼型系统，每个机翼有一个多元化翼型第telescopically装在一起，较低的翼型节被硬性安装在固定的关系，说身体，说翼型系统包括一个撤消的机制，降低上翼型章节说，翼型系统时，理想的和其后再将说，翼型制度，说收回机制包括多元化的联系互连说，部分和一个致动器的手段手术之间的连接说，身体和说，联系降低，并延长每翼型，及一个中间翼型延长之间的路段上的每说翼型，以便提供一个倒U -形翼型。

Results show that paste containing ground limestone can be destroyed at the temperature of 0—10 ℃ by the sulphate attack of thaumasite form.

造成这种研究现状的原因可能有以下 2 种：一是一般认为碳硫硅钙石只在0~5 ℃的温度条件下才有可

The results show that Irgacure1000 is preferable in the system and the rate is highest when the amount of Irgacure1000 is 3%;the drying condition has a considerable impact on the rate ; it decreases with the increase in neutralization degree;when NaOH is used as neuralization agent,the rate at the later period is higher than that when triethyl amine used; the structure of polymer has a certain effect on the rate and it accelerates with the increase in the ratio of PBA/DMPA and HEAD/DMPA.

结果表明，本体系优选光引发剂Irgacure1000的质量分数为3%时固化速度最快；干燥条件对光固化速度有很大的影响；随着中和度的提高，固化速度下降；用NaOH作为中和剂时，后期固化速度快于用三乙胺；聚合物结构对固化速度有一定的影响，随着PBA/DMPA和HEA/DMPA比例的提高，固化速度加快。

Several important parents of hybrid rice were used in this study and transferred with the grobacterium tume faciens strain EHA105 harboring Ti plasmid pCAMBIA1301, which contains a hygromycin resistant gene as the selectable marker and a β-glucuronidase gene as the reporter gene.
