According to the system ' s operational order , this paper explains how to solve some problems in the correction system , for instance , successively displaying autocad files , finding datum mark , drawing compartmentalization , view recognizing , scale consistency , orientation consistency , processing simplified means and displaying correcting results this thesis is supported by northwestern polytechnical university “ electronics teaching material budget 本文依照批改系統的工作順序,闡述了解決盤蓋類作業批改系統的技術問題,重點表述了作業圖連續顯示、基準點定位、區域劃分、視圖識別、方向一致化、比例一致化、簡化畫法處理以及結果顯示方法的處理方法。

It not only gains the physical contrastive datum mark , but also improves the blm stability . cyclic voltammetry is used to study the characteristic of blm attached to metal surface , as the forming of blm , the voltammetric characteristics of blm , the selection of ion and measurement of different ki concentration 就以上提出的處理方法,采用循環伏安法詳細研究了金屬表面所覆blm的基本性質,如:膜形成液的配制、膜的形成、膜電阻、膜的伏安特性、膜的擊穿電壓、離子的識別性及對不同濃度的碘化鉀溶液的測試。

Fourthly , according with the analyzing of flow measurement , we research the main problems needed to be solve in the process of measurement , such as analysis and measurement of the internal resistance , selection of excitation frequency , stable signal datum mark and restraining common mode interference , restraining for serial mode interference and working frequency interference ; transporting and shielding the flow signal , constant current excitation and magnetic field equalizing , flow measuring 第四,根據對流量測量問題分析的,深入研究了設計過程中需要解決的主要問題。如內阻分析與測量;勵磁頻率的選擇;穩定信號基準點與抑制共模干擾;串模干擾與工頻干擾抑制;流量信號傳輸與屏蔽;恒流勵磁與磁場補償;流量測量點的選擇等。

During construction of donghai bridge of yangshan deep - water port , bedrock bench mark , which is an important surveying datum mark , played an important part in control survey and elevation transmission 摘要基巖標是重要的測量基準設施,在洋山深水港東海大橋的工程建設中發揮了控制測量與高程傳遞的重要作用。

To use the athwart gradient protection which takes the end of dam as the datum mark will reduce the digging depth of the stilling basins is reducing , and increase the energy dissipation rate 采用以壩體末端為基準面的壩體逆坡防護時,消力池挖深減小,消能率提高,壩面平均流速減小,壩區防護難度降低。
