  2. However, owing to its opening, the information which is published on internet subject to many attacks, such as unauthorized wiretapping, intercepting, destroying, copyright infringing, abusing, hacker attaching and virus infecting, etc. because digital information on internet can be copied, modified and transmitted, copyright infringing on internet is becoming more and more serious ; now information tech is used more and more in the society, domain that internet concerns spreads fast, it play an important role in many fields, such as bank, business, government, army and so on. in these fields, demand of keeping secret is increasingly imminent

    然而正是由於它的開放性給在internet上發布、傳輸的信息帶來了巨大的威脅：網上的信息會被非法竊聽、截取、篡改或破壞；由於internet上的數字化信息可以被很方便地復制、修改和傳播，因特網上侵權問題越來越嚴重；並且，隨著社會日益信息化， internet所涉及的領域越來越廣，在諸多領域起了非常重要的作用，如銀行系統、商業系統、政府部門和軍事領域，這些領域對信息的安全保密要求也日益迫切。
  3. If the digital signature is valid, the trusted application domain host passes the signature information as evidence to the runtime s policy mechanism

    如果數字簽名有效，則受信任的應用程序域宿主將簽名信息作為證據傳遞給運行庫的策略機制。
  4. From theoretical analysis, we know the existing demodulation methods have limitations as following : one is that the subtraction of the two signals frequencies will display as the result of demodulation when we demodulate two time - domain adding signals without modulating information ( fault information ) ; the other one is that aliasing phenomenon will occur as a result of getting absolute value, detection or square in the process of generalized demodulation analysis, such phenomenon will result in some superfluous frequency composition on the frequency spectrum, which will puzzle the detec tion of mechanical vibration. if the sampling frequency is selected from a suitable range, the aliasing phenomenon will be avoided ; the last one is that aliasing frequencies will be produced in zoom demodulation analysis because this algorithm cannot employ digital low - pass filtering to avert the folding frequencies of higher harmonics in the process of zoom sub - sampling

    現有的解調分析方法存在以下三種局限性：將不包括調制信息（故障信息）的兩時域相加信號，也以其頻率之差作為解調信號而解出；廣義檢波濾波解調分析中，由於取絕對值、檢波或平方過程可能產生混頻效應，在解調譜中表現為無法分析的頻率成分，並由此推導出避免這種混頻現象的采樣頻率的選取范圍，從根本上避免此類誤診斷的產生；幾種細化解調分析新演算法中，因為無法在細化分析的選抽時進行數字低通濾波，有可能會出現調制頻率的高次諧波成分發生頻率混疊而反折到低頻部分的現象。
  5. With the rapid development of internet, digital library information resources are increasing with geometric series. in the face of tremendous amount of network resources, how to organize and describe digital library information resources so as to readers can find and utilize them expediently, is a problem that the librarians must solve urgently. firstly, this article describe the digital library information resources is different of other resources. it has its only orgnize and orgnize way. secondly, standards and specifications in the contents creation and resources description can be created in the course of the building of digital information resources. in these days, there are many metadata schemas in organizing digital library information resources. metadata schemas for resources description and domain specific markup languages have evolved dramatically during the last several years. this paper analyzes and discusses several metadata schemas. dublin core has been dramatically applied to the libraries for its advantages

    隨著internetr的訊猛發展，數字圖書館信息資源呈幾何級數增長。面對浩如煙海的網路信息資源，如何來選擇一種對數字圖書館的信息資源進行組織與描述的標準，以方便讀者查找和利用，成為圖書情報學界急待解決的問題。本文首先介紹了數字圖書館信息資源不同於其它的信息資源的特點，提出數字圖書館信息資源有自己獨特的組織原則與組織方式；其次，在數字圖書館信息資源的建設中，在內容創建和資源描述方面時應遵循相應的標準規范，目前存在的多種組織數字圖書館信息資源的元數據標準，其中以處理文獻資源為基本目的的元數據標準和專業置標語言近年來都在以前所未有的速度向前發展。
  6. The rtmaad system was integrated with digital signal processing ( dsp ), global information system ( cis ), optic time domain reflective ( otdr ) meter technology, wave division multiplexing ( wdm ) technology, etc. the rtmaad system made a realization that optical cable " s abort is auto located exactly. at the same time, the rtmaad system can monitor and diagnose both the optical terminal " s fault and power " s error of the stations of the fiber optical transmission network

    Rtmaad系統綜合應用了數字信號處理、地理信息系統、光時域反射測量和波分復用等技術，實現了光纜中斷故障的自動準確定位，同時將光纖系統傳輸站的光端設備和電源設備的監測融合到一起進行故障實時監測和診斷。
  7. To promote information service ability of digital libraries, a browsing and searching personalized recommendation framework based on the use of ontology is described, where the advantages of ontology are exploited in different parts of the retrieval cycle including query - based relevance measures, semantic user preference representation and automatic update, and personalized result ranking. both the usage and information resources can be exploited to extract useful knowledge from the way users interact with a digital library. through combination and mapping between the extracted knowledge and domain ontology, semantic content retrieval between queries and documents can be utilized. furthermore, ontology - based conceptual vector of user preference can be applied in personalized recommendation feedback
