The emcn model is set up by use of flux - tube method . in this method , the segment in which the flux density is relatively even is considered to be an element , the permeance of each element can be calculated by use of conventional method . finally the permeance network can be set up by connecting each node with permeances , then the parameters and performance can be obtained 其基本思想是通過磁通管原理,把電機內部磁通密度相對均勻的部分看作一個單元,計算出單元的磁導,最后再把各個節點用等效磁導連接起來構成一個磁導的網絡圖,再根據電路的基本解法求得各個節點的磁位,從而求得電機的參數和性能。

In this thesis , modeling of the characteristic of the ir jamming is discussed . the attenuation characteristic of ir radiation through atmosphere is analyzed and the atmospheric permeance of ir radiation is given . the design ideas and implementation method to generate dynamic ir images with computer are addressed 在論文中,討論了干擾彈的建模,分析了紅外輻射在大氣中的衰減,總結出大氣透射比的工程計算方法,論述了本文動態生成紅外圖像的設計思路和實現方法。

Calculating supply amount of karst underground water in spring valley by synthetic permeance coefficieint method is introduced . the question of error in observing all area balanced calculation in fengfeng mine area is expouned 應用綜合滲入系數法進行泉域巖溶地下水補給計算,解決了峰峰礦區用小流域觀測全區均衡計算過程中誤差較大的問題。
