系統根據活塞環cad系統生成的介面數據，通過伺服電機的轉角位置控制自主研製的高性能微位移進給機構產生給定的位移，以完成活塞環輪廓的仿型加工。系統採用速度、位置閉環控制及前饋控制理論，以提高系統的控制精度。活塞環cad系統以彈性力學和數學方法為基礎，根據常用的計算模型與活塞環參數自動生成數控加工系統所需的精確的介面數據，實現cad / cam一體化。With an introduction of the moving block system applied in wuhan rail transit project, the author analyzes atc operation mode which is based on moving block technique, and fallback mode, an auxiliary safety operation when fault occurs in moving block system, finally describes the failure management in the operation of the 1st phase of wuhan urt line 1
摘要以武漢軌道交通1號線一期工程信號系統的移動閉塞為例，介紹了移動閉塞技術下的atc模式以及針對工程項目制定的運營輔助手段後退模式，並討論了一期工程中運營的故障管理策略。The current situation of the human resource in the area of northwest of china and the cause of its formation. when the quantity of the human resource, its culture quality and the efficiency of its use, as well as its condition of being distributed in different industries is analyzed, the typical characteristic of the human resource in the area of northwest of china has been discovered in the following : ( 1 ) the human resource is rich in quantity and has a higherich in quantity and has a higher ; ( 2 ) its labour force has a lower quality, and the resources about science, technology and education are inequality in this area ; ( 3 ) the problem of being short of talented people is serious ; ( 4 ) the talented people now available is inequality in different industry, and the labour force mainly depends on their physical strength, and then, the cause for this phenomenon has been discovered in the following : ( 1 ) because of the local population policy, the population in this area increased rapidly ; ( 2 ) the backward economy impacts the human resource on its education and employment level ; ( 3 ) for its poor natural conditions, a closed and backward idea is formed in some peasants and herdsman ; ( 4 ) the lack of the mechanism of encouraging competition in personnel policy and scientific research field resulted in the loss of the vast number of talented people and inefficient in its use
西北地區人力資源開發現狀表現為：人力資源數量豐富，其中少數民族人口比例較高；人力資源文化素質水平較低；對現有人才資源使用效率不高；人力資源在產業間分佈不平衡，就業層次較低。造成問題的原因有：少數民族的人口政策是造成西北地區人力資源數量增長過快的重要原因；經濟發展水平制約了人力資源受教育的程度和就業層次；閉塞的自然環境，使人們難以突破封閉、陳舊的觀念；人事管理制度缺乏競爭、激勵機制，造成了人力資源使用效率不高。經過了理論分析和現狀調查之後，得出了人力資源開發的理性思考，即充分認識人力資源開發的戰略意義；發展教育是人力資源開發的前提條件；人力資源開發過程中要高度重視人才引進戰略的實施；人力資源開發要從本國（或本地區）實際出發，突出特色。Secondly, on the basis of the basic structure of the brake control system, the theory of brake task programming is studied and analyzed thoroughly. on the condition of automatic train protection, the fixed block system and moving block system the brake task programming method is brought forward
