論文首先分析了風機運行特性及其最佳風能利用原理，通過模擬及實驗驗證了採用直流電機的輸出特性模擬風力機的最大輸出功率曲線的可行性，並給出了模擬系統的硬體結構；然後為了實現交流勵磁發電機有功、無功功率獨立調節機理，分析了交流勵磁雙饋發電機的數學模型和在追蹤最大風能捕獲變速恆頻風力發電時必需的定子磁鏈定向矢量控制策略；針對雙饋發電機轉子能量雙向流動的要求，提出並設計了具有能量雙向流動能力的雙pwm交流勵磁用變頻器；最後為實現從理論到實踐的全面研究，研製出了一套小功率完整的雙pwm變頻器交流勵磁的雙饋風力發電機實驗系統，進行了空載、並網、同步速及上、下的發電運行等一系列的運行實驗；所完成的模擬和實驗研究均驗證了理論、模型和控制策略的正確性、可行性。On the other hand, inhibitory areas of ftc could be abolished partially or completely during bicuculline application. these results showed that gabaergic inhibitory afferent projections to recorded neurons were activated by random resonance caused by weak noise in cochlea, which provided inhibitory input for sharpening frequency tuning and made neuron more precisely analyze sound signal near its bf. therefore, this experiment presented a possible evidence of cellular level for interpreting why human and animal could extract or capture sound signal of specific frequency from the environment with competing noise
說明山弱噪聲引起的耳蝸隨機共振在_ _仁行傳入過程中可能激活了至所一記錄的jc神經元的gaba能抑制性神經迴路，這種gaba能抑制為銳化神經元頻率調諧提供了一種抑制性輸入，使ic神經元對靠近最佳頻率的頻率分析變得更為細致和精確，由於聲頻率是聲信號的重要參數和信息載體，頻率調諧的銳化意味著對聲頻率分析能力增強，從而為解釋人們為什麼能從充滿噪聲的環境中捕捉或提取與行為學相關的信號提供了一種細胞水平的實驗證據。The characteristics of the intrinsic frequency distribution of the framed steam turbine - generator set foundation are summarized ; it can been seen that the base plate of the framed foundation does not have much effect on the dynamic response of the foundation, and that the " amplitude method " is better than the " resonance method " among dynamic analysis methods. when designing a framed foundation, as long as the load - bearing capacity and stability is ensured, a flexible pillar is better, the amplitude of vibration can be controlled through adjusting the particle quality in foundation design
論文最後總結了框架式汽輪發電機組基礎固有頻率的分佈特點；指出框架式基礎底板本身對基礎的動力響應影響不大，認為動力分析方法中振幅法優于共振法；並指出框架式基礎設計時，在滿足承載力和穩定性的前提下，柱子應以柔為佳；設計中可以通過調整質點的質量來達到控制基礎振幅的目的。In the power - amplifying grade of drive circuit, the system adopts a method of high / low voltage drive that is different to the conventional drivers. so the high frequency performance of the system is improved and the load support capability of step motor is increased. by the software method, the control principle of the optimum increasing / decreasing frequency of step motor is achieved
