Abstract : the basic theory and function of cd retrieval and systemic constitution of multimedia searching databases cd co - developed by the author and tsinghua university is stated. the system consists of load, databases, html browser, editing and print. the system almost holds out multimedia format and has powerful retrieving function, it not only involves all methods of manual retrieval, but also carries out logic and mixed retrievals. the process in fact is one during which data are matched. the result shows : cd databases make retrieving popularized, simplified and have vast foreground in storage
文摘:介紹了作者與清華大學合作開發的多媒體全文檢索數據庫光盤的系統組成與光盤的檢索功能及原理.系統由標引系統、資料建庫系統、超文本瀏覽器、編輯出版系統組成.該系統幾乎支持所有的多媒體格式，具有強大的檢索功能，不僅囊括了手工檢索的全部方法，還可進行模糊邏輯檢索和任意混合檢索.其檢索過程實際是一個數據匹配的過程.實踐證明，光盤數據庫使檢索大眾化、簡單化和普及化，在信息儲存方面前景廣闊 -

Compares the two schemes with traditional air conditioning system from the economic aspect, and recommends that the ice storage unit and the refrigerating unit for base load be properly matched to improve the system economics
從系統經濟性方面將兩種方案與常規空調系統進行了比較，指出在冰蓄冷系統設計中應合理匹配基載主機與蓄冰主機，優化系統的經濟性。 -
However these converters become more complicate. phase - shift zvs technique has been used in bidirectional dc / dc converters since it can realize zvs for all switches without auxiliary switches. however when the amplitude of input voltage is not matched with that of output voltage, the current stresses and rms currents of the converters become higher, in addition the converters can not achieve zvs under light - load condition
諧振、準諧振或多諧振技術方案，變換器的電壓電流應力較高，變頻控制增加了濾波器設計的難度；能量緩沖吸收電路或有源鉗位電路方案，由於需要增加多個額外輔助元件，增加了變換器的復雜性；全橋相移技術方案，由於主電路無需增加額外元件，只需利用相移控制，即可實現軟開關，因此引起關注。 -

In order to fully develop the theory of squeezed branch piles, in particular, the justification of its superior performance in terms of the bearing capacity and sinking displacement, we have derived the analytical formulas of the axial load and the strain at arbitrary depth ; based on existing static loading test results and research on belled pile, together with the analysis of on - site testing data, we have applied the expand theory on sphere holes to the computation of radial stress of squeezed branch piles under hole expansion ; taking the oil pressure of hole expansion in to account, we have find the a branch force under certain hole pressures, hence we can estimate the maximum bearing capacity of single piles ; we have introduced the experiential formulas for the bearing capacity of squeezed branch piles based on its stress characteristic and pile testing data ; we have also done numerical simulations of squeezed branch piles utilizing finite element method software ansys ; we have matched the simulation res ults with those of on - site basic load experiments, regenerating the distributions of stress fields and strain fields of squeezed branch piles, and from those distributions, we can determine the optimal distances between plates and piles
為了完善支盤樁的設計理論，探求支盤樁高承載力和低沉降量的內涵，本文推導出了支盤樁任意深度的截面荷載以及位移隨深度變化的理論公式；基於已有的靜載試驗成果及有關擴底樁的研究成果，從對現場測試數據的分析，將球形孔擴張理論引入到支盤樁擴孔時徑向應力的計算，考慮到擴孔時的油壓數據，求得某一孔壓下的支盤力，據此估算單樁極限承載力；同時根據對支盤樁的受力特點和試樁數據的分析，提出了支盤樁承載力計算的經驗公式；用有限元分析的方法，利用大型有限元分析軟體ansys對支盤樁進行數值模擬，並將模擬結果同現場的靜載試驗結果進行對比，再現了支盤樁在荷載作用下土中應力場和位移場的變化，根據應力場和位移場的變化范圍，指出最佳盤間距和樁間距；為支盤樁的設計和施工提供了一個可量化的設計依據。
