The whole thesis was made up of seven parts. the first part provided the background, significance and aims of this research ; the second part briefly reviewed the progress and the trend of the researches about the relative fields at home and abroad, then concluded that the present researches were mainly focusing on mineral cities and the qualitative description of mineral economics, which lack in quantitative analysis and utilized models ; the third part defined mineral region according to two indexes, and discussed the theoretical basis of the economic sustainable development of mineral region ; the fourth part systematically analyzed the current situation of the economic sustainable development of huangling county, emphatically discussed the coincidental relationship between mineral exploitation and economic development as well as the reasons for the recession of mineral economic ; the fifth part, drawing on the experience of transforming industry and renewing economic in mineral cities ( region ) at home and abroad, put forth the foundation train of thought of the economic sustainable development huangling county, and programs and smocks the economic development of huangling county using the method of systematic dynamics, presented the model of the economic sustainable development of counties by comparative analysis of three plans ; the sixth part provided some policed suggestion and measure for the economic susta inable development of huangling county
全文分為七個部分：第一部分：提出研究的背景、意義與目的；第二部分：簡要回顧了國內外相關領域的研究進展與趨勢，指出當前研究主要集中在礦業城市與礦業經濟的定性描述，缺少定量分析和應用模型；第三部分：依據兩組指標界定礦業區域，探討礦業區域經濟可持續發展的理論基礎；第四部分：對黃陵縣域經濟可持續發展現狀進行系統分析，重點探討了礦產資源開發與經濟發展的耦合關系及其礦業經濟衰退的原因；第五部分：在借鑒國內外礦業城市（地區）產業轉型與經濟新生經驗的基礎上，探討了黃陵縣域經濟可持續發展的基本思路，並運用系統動力學方法對黃陵縣域經濟發展進行規劃與模擬，通過三種方案的對比分析，提出縣域經濟可持續發展模式；第六部分：黃陵縣域經濟可持續發展的政策建議與措施；第七部分：主要結論及進一步研究的問題。Analyze item by item the position of unintact cycle, the running clearance of unintact cycle, locking - deform, datum dimension regulating, repeatly install, power voltage wave and marking running etc. at the same time, we give the calculating formula to calculating the running marking random error, and use it to calculate the system error of big diameter measure instrument - - datum dimension frame error, gyro - wheel diameter error, error caused by circumstance temperature, error caused by backing distance, angle error, delay error of data collecting circuit, lathe main shaft running error, workpiece install partial error
對不完整圓的位置、不完整圓的轉動間隙、鎖緊變形、基準尺調整、重復安裝、電源電壓波動、標記轉動等隨機誤差進行了逐項分析，並給出轉動標記隨機誤差的計算公式。對大直徑測量儀的系統誤差?基準尺尺架誤差、滾輪直徑誤差、環境溫度引起的誤差、後退距離引起的誤差、角度誤差、數據採集電路延時誤差、車床主軸回轉誤差、工件安裝偏心誤差分別進行了計算，最後對誤差進行合成。
