  1. For the first time we investigate detailedly on the theory of the conductor - centered arbitrarily - shaped helical groove structure. we divide the arbitrarily - shaped helical groove into many consecutive small rectangle area to approximate the original groove. the recurrence relation of the admittance is obtained

    首次對具有中心導體軸的任意槽形螺旋槽結構的普遍理論進行了研究，通過以多層矩形階梯來近似代替任意形狀槽的邊界的方法，同時對導納的遞推關系進行了詳細的推導。
  2. This paper describes a reconstructive algorithm which is based on network theory for electrical capacitance tomography technic. there are twelve electrodes in the system. the permittivity distribution of flow with two components within a pipeline is reconstructed. assume the permittivity distribution of the region to be reconstructed. then whole measured area is discretized into a network composed of capacitance. the measurement circuit which contains a pair of source electrode and detecting electrode is taken as a four - terminal network. the across admittance of the four - teminal network is proportional to the capacitance between the source electrode and the detecting electrode. modify the distribution of the permittivity according to the difference between the calculated capacitance and measured capacitance. the experimental results show that this algorithm is effective and can coverge

    本文描述了一種用於兩種成份的流體成像的12電極電容層析成像新方法.該方法基於電路的網路理論，首先對重建區域假定一個介電率分佈，用電容網路作為離散化模型，將每一個源電極和探測電極對組成的測量電路看作一個四端網路，該四端網路的跨導與源電極和探測電極之間的電容值是線性關系，這個電容值和測量得到的電容值之間存在誤差，根據這個誤差對修正介電率分佈.通過對不同介質分佈作的模擬實驗結果，證實了該演算法是有效的，收斂的
  3. Therefore, should through the establishment strict mining area environment admittance mechanism, the strict mining right licensing system, establish the mining area environment to restore the government earnest money system, the perfect mining area environment legislates and is clear about the administrative law enforcement main body, strengthens the market in environmental protection function, strengthens the administrative guidance and the regulative mechanism, after takes to shut the ore correlation systems and so on environmental protection to resolve the mine environment question prominent contradiction

    為此，應通過建立嚴格的礦區環境準人機制，嚴格的礦業權許可制度，建立礦區環境恢復治理保證金制度，完善礦區環境立法及明確行政執法主體，強化市場在環境保護中的作用，加強行政引導和調控機制，重視閉礦后環境保護等相關制度來解決礦山環境問題突出的矛盾。
