解釋
主磁場線圈-
In the past, two following respects that the study on magnetoelastic stability theory was main and centralized : first, setting - up and revision of the soft ferromagnetism plates buckling theory model ; second, represented by the tokamak thermonuclear current - carrying rector coil, the stability of current - carrying coils and poles under magnetic field has been studied
以前，對磁彈性穩定性理論的研究主要集中以下兩方面：一、軟鐵磁性薄板屈曲理論模型的建立及修正；二、以tokamak核聚變反應堆環向磁場載流線圈為代表的對載流線圈及載流桿件的穩定性研究。 -
The finite element method ( fe '. i ) is adopted to analyze the effects of the numbers of coil turns, current intensity and current frequency upon the rate of joule heat generation in details. the thermo - radiation analytical countermeasures of various types are adopted to carry out the numerical analysis of the effects of the crucible with different shapes and sizes and the blind holes with different depths opened in the tops of crucibles as well as coil positions upon the thermal field distribution whereby solving the main problem of field the thermo - field design of the induction - heating sic crystal growth system. a new combination idea of the thermo - field design obtained by means of the united design of the thermo - insulator and blind holes has been presented
採用有限元分析方法對線圈匝數、電流強度、電流頻率等對焦耳熱產生速率的影響進行了詳細的分析討論；採用不同的熱輻射分析策略，對不同坩堝形狀、坩堝頂部開設不同深度的盲孔以及線圈的位置等對熱場分佈的影響進行了數值分析，解決了感應加熱碳化硅晶體生長系統熱場設計的主要問題，提出了通過絕熱層與盲孔的聯合設計獲得所需熱場設計的思路，給出了根據軸向溫度梯度的波動對線圈位置實行動態調節以控制熱場的理論依據。
