  1. As it ' s proprietary, a large numbers of bibliography resource ca n ' t be provided to common readers of internet. along with the development of network technology, it has a instancy need to conversion marc format to the information that the browser can recognize. the language xml not only can expresses the metadata, but also can show the content of data. lt can provide individuation page layout

    Marc格式是目前圖書館館藏資源的主要表示格式，由於其專用性，使得目前大量的書目資源無法通過一般的搜索引擎向internet用戶提供，隨著網路技術的不斷發展，迫切需要將marc格式的數據轉換成常用瀏覽器所能識別的信息，為大眾提供服務，可擴展標記語言xml不僅可以表達元數據，而且可以揭示數據的內容，提供個性化的頁面顯示，用xml語言對marc數據進行描述是解決這一問題的有效途徑，文章提供了marc數據的xml表示方法和實現途徑。
  2. At present, the typic harmful current detection methods are the fast fourier transform algorithm in frequency domain and methods based on the instantaneous reactive power theory, these methods all require some transform and quick, real - time calculating, so high precision analog multipliers or high speed dsp chip with fast a / d are needed, this results in complex circuit and high cost ， which have restricted the development of apf

    目前畸變電流檢測常用的方法有頻域法的fft和基於瞬時無功理論的畸變電流檢測法。這些方法均有一定的變換，需要快速、實時運算，因此必須使用高速的數字微處理器和高性能a / d轉換器，這必將大大提高系統成本，使得電路結構復雜，在一定程度上限制了有源濾波器的發展。
