解釋
定量骶髂閃爍照相術-
During the high - voltage device design, the thick epitaxial layer ldmos which is compatible with current technology was researched. this device used piecewise vld and multiple region structure f reduce field layer. the using of the f reduce field layer effectively reduce the surface electric field of the device, shorten the length of its drift region, enlarge the choice of range of the ion implant dose of the p layer, and effectively restrain the disadvantageously affection on the breakdown voltage of the interface charge qss
在高壓器件研究中對與現有工藝相兼容厚外延ldmos進行研究，該結構採用分段變摻雜多區p ~ -降場層，有效降低器件的表面電場，縮短器件的漂移區長度，增大p ~ -降場層注入劑量的選擇范圍，並有效地抑制界面電荷qss對器件耐壓的不利影響。 -
All these changes, which are of importance to subsynchronous oscillation analysis, cannot be described with the quasi steady state ( qss ) model any more. therefore, the deficiency of qss - model - based eigenvalue method is pointed out and a novel method named complex torque coefficient - test signal method is adopted to analyze the subsynchronous oscillation caused by hvdc or facts devices
基於此，指出了採用準穩態模型進行hvdc系統次同步振蕩分析的局限性，並引入了分析hvdc或含有facts裝置的系統次同步振蕩問題的方法：復轉矩系數- - - -測試信號法。 -
During the research of the run - time engine, we investigate the process of condition fragments instantiation, and make parameter instantiation by qss and user input
在處理引擎的研究中，我們根據qss和用戶輸入的實例化參數值，分析了條件片斷的實例化過程。 -
Finally, we implement that query set language encodes large numbers of possible queries, the tql expresses and calculates queries, and the algorithm from qss to tql and the one from tql to xquery
最後，實現了qss對查詢要求的描述、 tql語言的表示和計算、以及qss到tql的轉換演算法和tql到xquery查詢表達式的轉換演算法。
