  1. There are advantages to the end user even when the udm is constructed only as a thin layer over the data source : simpler, more easily understood model of the data, isolation from heterogeneous backend data sources, and improved performance for summary type queries

    即使udm只是作為數據源上的瘦層來構造，對于最終用戶而言也有益處：更簡單、更容易理解的數據模型，與異構的後端數據源相隔離，並且匯總類型查詢的性能也有所提高。
  2. Taking partial discharge as the first monitoring item, this thesis designed a database that can save, retrieve, input or output, plot partial discharge data, and constructed a system of data subjects that can be applied to partial discharge detection and discharge type recognition

    本文設計了具有存儲、查詢、數據導入導出、繪圖顯示等功能的數據庫，設計了適用於局放監測和故障類型識別的數據對象。
  3. A new biased estimator so - called ridge type - generalized inverse ( rg1 ) estimator is constructed after summing - up the historical and present condition of biased estimation theory in surveying data processing. the prosperities of rg1 estimator are studied especially by pitman ' s criteria. the other biased estimator so - called partial root root ( prr ) estimator is generated

    通過對有偏估計理論在測量數據處理中的應用歷史和現狀進行總結和分析，構造了未知參數的一種新的有偏估計方法? ?嶺型廣義逆估計，對其性質特別是在pitman準則下的若干性質進行了討論；接下來構造了另一種新的有偏估計方法? ?部分根方估計，該估計的最大特點在於它是一種部分壓縮估計。
  4. The study instructs simulating valve leakage experiment, perfects valves leakage test technology and bases theoretically for applying valve leakage test in practice. the test stand is constructed and instrumented to accept a variety of valves in order to determine which characteristics of acoustic emission change with leakage rate. the data for each valve type is generated by varying valve type and working medium

    建立模擬在用承壓閥門內漏實驗臺，研究典型閥門內漏聲源的聲學特性，確定聲發射特徵參量與泄漏率的關系，為定量評價閥門泄漏率提供實驗數據；通過對不同類型、不同規格、不同工作介質下的典型承壓閥門內漏的實驗研究，確定閥門內漏最佳檢測區域，建立在用承壓閥門內漏聲學檢測方法。
