    本試驗也發現了六大策略中，認知策略和補救策略對學生高考成績的差異有更強的解釋力。
  5. In this paper, we make an analysis on the difference of the land price and the cause of the difference under different transaction, different uses and different property right, the income distribution at the different transaction forms, by the way of land price investigation in tangshan urban fringe. at the same time, we study on the factors which influence the compensation for expropriation and the law of land price ' s space variation

    通過對唐山市城鄉結合部土地價格的調查，本文分析了城鄉結合部不同交易形式、不同用途和不同產權下的土地價格之間的差異以及這些差異存在的原因，在不同的交易形式下土地收益的分配情況；考察了征地補償的影響因素以及地價的空間變化規律。
  6. Specific issues examined are : compensation for the variation of the stator resistance, the offset error of the dc bus voltage, the voltage error generated by the forward voltage drop the dead time of the switches, improvement of the steady state performance, and the speed sensorless control for the pmsm dtc drive system are of major concern in this thesis

    定子電阻變化，直流母線電壓漂移，開關器件反向相電壓降、逆變器死區時間引起的電壓誤差的補償，提高系統穩態運行性能以及永磁同步電機直接轉矩控制的無速度傳感器運行方案等問題都是本文研究的重點。轉矩的快速響應是直接轉矩控制演算法的一個卓越的性能。
  7. Constant stator magnetic linkage control frequency converter includes power devices utilizing igbt, drive circuit using three - phase drive ic with multiple protection functions. pwm signal formation circuit in the way of voltage space vector control and realized with pld ( programmable logic device ) devices and compensation for the influence of supply voltage variation and stator resistance voltage drop

    其中，恆定子磁鏈控制變頻器的設計中主電路採用功率器件igbt ；驅動電路採用三相多功能集成驅動晶元； pwm脈寬調制信號產生電路採用電壓空間矢量控制方式，由pld器件實現；對電源電壓變化及電阻壓降造成的影響進行了補償。
  8. The hspice simulation result shows a temperature coefficient of 11 ppm / " c from - 40 ? to 100 ' c and output voltage variation of 1mv for supply voltage range from 8 v to 18 v. due to novel curvature compensation, the circuit structure of the proposed reference is simple and both chip area and power consumption are small
