Linear induction motor is an important kind of machines which have some merits such as simple structure, low cost, durability, convenience for maintenance etc. the subject of this thesis is to study a big circular ring linear induction motor, and the major works in this thesis are summarized as follows : ( 1 ) considering the effects of the finite length of primary core, one - dimension analytical solution for the air gap field is cited in this paper. based on it, the single layer winding magnetic field is studied. considering whole - pitched and short - pitched winding configuration with odd poles and half - fulled slots in both ends, the double - layer winding magnetic field is analyzed, respectively
本文對大圓環直線感應電機進行了深入細致研究，內容包括： （ 1 ）本文採用有限長行波面電流作用於有限長鐵芯上的模型，引用了氣隙磁場一維解，研究了單層繞組磁場，奇數極半填槽雙層繞組在採用整距和短距時磁場的分析、比較，簡單介紹了二維解； （ 2 ）用有限元軟體ansoft對大圓環直線感應電機空載氣隙磁場進行了靜態分析，並分析了結果； （ 3 ）用軟體進行了額定電壓下的瞬態分析，得到了轉矩，位移，轉速隨時間變化曲線圖，利用單極性霍爾元件測定轉速並與軟體計算結果進行了比較，採用等效電路法計算了堵轉時的最大電磁力並做實驗進行了驗證，由實驗測得了三相電流波形，並與計算結果進行了比較，對其不對稱性進行了定性分析。And get a conclusion that labor - compressed products also have large comparative superiority, capital - compressed and technology - compressed products " comparative superiority is rising, and resource - compressed products belong to comparative inferior position. we also find that fluctuate in export amount mainly comes from fluctuate in labor - compressed products such as clothing and textile. so enhancing the proportion of high - attached - value product is a main task
並在出口產品結構現狀分析及各類產品對出口貢獻率分析中得出結論：紡織品服裝等勞動密集型產品比重仍然較大，這些產品缺乏競爭優勢，其出口波動較大，是出口總額增長不穩定的主要因素；雖然機電產品、高新技術產品等具有競爭優勢的產品出口發展迅速，已佔據出口的主導地位，但是其比重仍然偏小，不足以維持出口總額的持續穩定增長，其產品內部結構存在單一化等缺陷。Power : put to say to, and the sum settle the power to is just valid index sign that evaluate the to put the function. it points within the scope of certain of the wave lose true, and the make longer a work can biggest power of the output s. enlarger while connecting into the box of the different resistance that exportation power can have different, usually the enlarger can mark clearly its sum to settle the exportation resistance ; for example a sum that set enlarger while loading a resistance to settle the exportation power to the, and load the resistance to may increase the the above. because the power there is method of various marks, some and illegal factory to can have intention to exaggerate the data, purchase or choose the hour to want with physically hear the to take in to distinct, comparison
它是指在一定的諧波失真范圍內，功放長期工作所能輸出的最大功率。放大器在接入不同阻抗的音箱時的輸出功率會有所不同，通常放大器會標明其額定輸出阻抗例如一臺放大器在負載音箱阻抗為時的額定輸出功率為，負載阻抗為時就可能增加到以上。因為功率有多種標法，某些不法廠商會有意誇大數據，購買或選配時要以實際聽音加以區別比較。
