首先，本文將面向對象方法和關系數據庫技術結合起來，採用psmis的多層客戶?服務器體系結構實現對保護信息的管理，以便供電段技術人員查看保護裝置的整定值、各種報告、故障錄波（系統不僅能顯示波形，還能動態顯示波形每一點的峰值、有效值、相位，甚至阻抗值及阻抗角、諧波含量等） 。The result shows that the electric property and position and occurrence of anomalous body, the resistivity of bed rock, can be obtained correctly however only the composite value of resistivity and thickness of anomalous body can be determined because of equivalence
反演結果可準確反映圍巖電阻率、異常體的電性、位置和產狀；而由於同層等值現象，反演結果只能確定異常體的厚度和電阻率的組合值。By adopting a cash - in and cash - out fun - raising method, which pays for the various social security items of the current year through that year ' s fiscal revenue and through a part of the earnings from the enterprises, the coverage of our country ' s traditional social security system is limited to workers of state enterprises and to workers of some collectively owned enterprises. this method, owing to its lack of accumulated funds and of figuring out estimates for its due payable responsibility, cannot possess long - term positive financial potentials. instead, it hinders us from establishing our modern enterprise system and prevents us from reforming our mechanism of using and financing the work force
我國傳統的社會保障系統，保障和覆蓋對象狹窄，基本上僅對國營單位職工和部分集體單位的職工提供保障，採取現收現付的籌資模式，根據需要和可能，用當年財政收入和企業收入中的一部分直接支付當年的社會保障各項待遇，沒有基金積累也沒有對制度未來償付責任的估計，這樣的制度不可能具有長期財務能力，也阻礙了勞動制度的改革和現代企業制度的建立。At present, the problem in testing sheet resistance for micro - areas is that probes must be set up at the suitable locations by handwork. in order to know the wafer ' s impurity distributing, we need test many times, so will waste a lot of time. if the wafer ' s diameter would be 300mm, this problem will be more serious. in this paper, image analysis is introduced, through pre - processing and edge picking - up, the probe tips are recognized. then probe tips will be aligned respectively in two perpendicular directions through driving stepper motors. thus the distribution of sheet resistance for whole wafer is got by automatic testing and it offers information for detecting the impurity distribution and the diffusion uniformity
這樣，完成200mm （ 8時）圓片雜質的擴散分佈需要對許多圖形進行測試，需要花費很長的時間，當測試300mm矽片時問題就更為突出。本文將圖象與視覺測量系統引入四探針測試系統中，對採集到的原始探針圖像進行預處理、邊緣提取等操作，以便實現探針針尖的識別，然後由電機控制實現探針的自動定位。這樣測試系統可以自動獲得全片的薄層電阻分佈，為超大規模集成電路檢測雜質分佈和擴散的均勻性提供信息。Skin effect is the tendency for alternating current to flow near the sruface of the conductor in lieu of flowing in a manner as to utilize the entire cross - sectional area of the conductor. this phenomenon causes the resistance of the conductor to increase. the magnetic field associated with the current in the conductor causes eddy currents near the center of the conductor which opposes the flow of the main current near the center of the conductor. the main current flow is forced further to the surface as the frequency of the alternating current increase
表面疚是指交流電流較傾向于導體的表面傳導而非流經整個導體截面的趨勢，這些現象會造成導體的電阻提高，與導體中的電流有關的磁場在導體中心部位產生過電流而阻礙了中心部位的主要電流，當交流電的頻率增加時，主要電流的流向會進一步被推擠到導體表面。分享友人
