According to the special desire for high production and efficiency in compound mining face and questions met in using scraper conveyor , analyzed on the structure of linepan and designed the c - linepan with casting back over and divided body . it has achieved good result after using 根据高产、高效综采工作面的特殊要求及在使用刮板输送机中遇到的问题，对刮板输送机的中部槽的具体结构进行了分析，设计出铸造封底分体式c形中部槽，使用后取得了良好效果。
It takes good use of these two numerical computation methods merits and it is valuable for defmiting the computation model of pile ? oil ; at the same time , it builds the computation model of compound pile foundation and uses the software ansys which is about finite element to build the mechanics model . in regular quality soil , the result worked by this way has good unanimity with traditional results , so it applies us strong evidence for using the way which this article tells us to solve problems which is difficult to handle in compound pile foundation , such as irregular quality , layer quality of the soil . at last , taking foundation soil ' s measuring data of liaoning technology university ' s test building for example , and using the way this article tells us to build compution module , we solve the sharing ration of pile and loading board 本文利用有限元与边界元耦合的方法求解桩土相互作用问题，充分利用两种数值计算方法的优点，对确定桩土相互作用计算模型是一次有益的尝试；同时建立了群桩相互作月的数学模型，并利用有限元分析软件ansys建立其力学模型，在均质土体中取得了与传统解答较好的一致性，从而为拓展利用本文所述建模方法，解决群桩作用机理研究中难以处理的土体成层、非均质等性质，提供了有力的根据；最后，以辽工大实验馆地基土实测资料为例，利用本文建模方法，求解出承台与桩的荷载分担比，对安全、经济地进行群桩基础设计具有重要指导作用和应用价值。
Through the analysis we found that the effect will become more obviously with the increase of thickness or width of superstratum and the decrease of the coefficient of foundation bed ; ( 3 ) anisotropy and nonlinear elastic f . e . m . model has been established and the effect of stress dispersion in compound two - layer foundation was analyzed on the base of the model . from the analysis we can conclude that the coefficient of subsidiary stress dispersion will amplify with the increase of thickness or width or stiffness of back - up coat ; ( 4 ) the formula which can be used in conventional calculation has been deduced for calculating the coefficient of subsidiary stress dispersion and it also has been affirmed to be reasonable through the checking calculation ; the whole theory of compound two - layer foundation has been brought forward in this paper and it ' ll enrich the theory of composite foundation 针对以上问题本文做了以下一些工作并得到若干结论： ( 1 )提出了“复合双层地基”的概念，并通过工程实例证明此概念的提出有其合理性和必要性； ( 2 )用弹性地基梁理论证实了复合双层地基确有应力扩散效应，且扩散效应随上覆硬层厚度、刚度的增加而增大，随下卧层基床系数的增大而减小； ( 3 )建立了非线弹性、各向异性有限元模型，并以此为基础分析了复合双层地基的应力扩散效应，得到附加应力系数随加固层厚度、宽度、刚度的增加而增大的结论； ( 4 )推导了可用于常规计算的复合双层地基应力扩散系数公式，并代入工程实例进行了验证。
In theoretical analysis , the motion of radially - emitted electron beam in diode region and drift region has been analyzed , and the relation between radial momentum or current of electron beam and the guiding magnetic field has also been studied , then the possibility to optimize the guiding magnetic field has been derived . the motion of radially - emitted beam electrons in smooth bore magnetron and smooth bore milo has also been studied theoretically . at last , the motion of radially - emitted beam electrons in compound axial and azimuthal magnetic field has been studied 在理论分析中,初步分析了轴向发射条件下电子在二极管区域和漂移区的运动规律,电子径向动量随着外加磁场变化的规律,以及电子束电流随着外加磁场的变化规律,还有二极管区域磁场优化的可能性;分别研究了有轴向磁场时以及有角向磁场时径向发射的电子在光滑阳极结构中的运动规律,最后分析了在轴向和角向复合磁场中电子的运动规律。
