数字式轴向柱塞泵 - In the paper each mathematic model of seepage in fractured rock masses is summarized . finite element analysis simulation equations of non - double porosity system model - equivalent continuum media model and discrete fracture network model are given , furthermore a coupling uniform model is formed which integrated with the merit of the two former models
本文综述了裂隙岩体渗流分析的各类数学模型，对于非双重介质模型? ?等效连续介质模型和离散裂隙网络模型分别给出了它们的有限元模拟公式，还进一步提出了结合上述两种模型优点的适用于复杂裂隙岩体的耦合统一模型。 - The numerical simulation equations of the border curves in term of and as well as the matching rules and the frequency dependence of microwave electromagnetic parameters of a broad - band homogeneous absorbing coating with a finite value of reflection loss are available . these results pointed out the direction to develop rams " . according to the radar - absorbing model , the optimized design of rams with thin - layer , light - weight , broadband and strong - absorbing is available by the simple genetic algorithms , which can effectively conduct the research work of rams to the detail . small but completely , the electromagnetic parameter ' s databases of rams that based on actual microwave absorbers have been set up , the object function has been constructed which conform to the involved goals , the adaptive coding measure is taken which extends the coding length dynamically adapting to the condition of the number of actual absorbers or the precision of thickness and absorber - volume - percentage , the decoding technique is initiated which satisfies light - weight and strong - absorbing as well as thin - layer and broadband by adopting of tracing variable restricting conditions dynamically to control total thickness . when decoding , the variable restricting conditions of thickness are dynamically traced , so gain the radar absorbing coatings of light - weight multiple - layer single - ingredient . similary , of thickness and absorber - volume - percentage , of light - weight multiple - layer multiple - ingredient . also , the rams ' demand to radar - absorb performance as frequency is met making use of the penalty function
