Vb link with fortran language is realized and solved successfully . both program interfaces are friendly and convenient to operate . the post - stall behavior of three specific compression systems is analyzed by the application of the post - stall behavior simulation programs developed in this paper 以三种特定的压缩系统为研究对象,展示了这两种过失速性能模拟技术的实用性和有效性,单级压缩系统的过失速状态的数值模拟结果得到了实验结果的很好支持。
Based on this arithmetic , the high frequency characteristics of five - cavity with open boundary is calculated by the code written in fortran language . then the transit effect of five modes of five - cavity with open boundary is also calculated using code mathcad and matlab . the results show that the working mode of five - cavity transit tube oscillator is 3 / 6 mode , and the analysis of the theory are in good agreement with the simulation results 根据从基于四腔渡越时间效应的自调制出发,经过一段飘移,然后再采用双间隙提取腔边耦合输出高功率微波的思路,采用粒子模拟方法优化设计出一种峰值功率为1 . 5gw ,频率为9 . 3ghz的六腔渡越辐射振荡器,并研究了它的一系列工作特性。
Finally , on base of the above research contents , a program is developed in fortran language by using this simplified method to analyse the ultimate strength of ship hull girders . in comparison with the results from some famous experts of international ship & offshore structures congress . this simplified method has engineering accuracy and can be used in the pre - phase of design 最后,在总结上述研究内容的基础上,本文编制开发了一套具有工程实用价值的船体极限强度的计算程序,经计算与来自国际船舶钢结构委员会著名学者的计算结果进行了比较,说明该程序简单、可靠,可方便地应用于船舶强度校核和评估。
For having a directly perception to the influence of interaction , the author completes program of calculating huge structure ' s dynamic properties which worked out by fortran language , and employ 3d incompatible isoparametric element figures out the dam properties in the condition of rigid foundation meantime . further the author calculates dynamic displacement of dam in software of matlab , ansys 为了对动力相互作用影响有一个直观的认识,作者完成了fortran语言编制的计算大型结构动力特性程序,并采用三维8结点非协调等参单元分析了坝体在刚性地基情况下的动力特性,并在matlab 、 ansys中计算了坝体的动位移时程曲线。
