若要拿一個人的工作成就來代表亞歷山大在他那個時期的數學特性,誰也不能比阿基米德更合適了。Since complicated differential and integral operations were involved in the kernel of the integral equation, we simplified the equation and got the nakano equation. as instances, the planar archimedean spiral antenna, the planar equiangular spiral antenna, the monofilar helical antenna, the conical helical antenna with fixed ascending angle and the conical equiangular - spiral antenna were analyzed through the moment method. all of the results matched fairly well with the references and experiment results
這種方法的積分方程的積分核里含有復雜的微積分運算,為了簡化計算,本文在推廣的海倫積分方程的基礎上,對方程進行了簡化,推導了nakano方程,並以平面阿基米德螺旋天線,平面等角螺旋天線,軸向模圓柱螺旋天線,具有固定升角的圓錐螺旋天線和圓錐等角螺旋天線為例,用矩量法求解了天線上的電流分佈,研究了螺旋天線輻射的寬頻帶特性,所得的結果均與參考文獻吻合很好。In this thesis, the concept of " fractal " and the recursive algorithm of fractal structure are depicted. the wavelength - independent character of archimedean spiral antenna and the space filled property of koch monopole are analyzed by the method of moment
本文介紹了分形的基本概念和分形結構的迭代演算法,採用矩量法分析了阿基米德螺旋天線的頻率無關特性和koch單極天線的空間填充特性。Substituted by a densimeter based on the archimedes laws, the online concentration measurement was further modified, and the quality of the measured data was improved with satisfactory accuracy and repeatability. nevertheless, information obtained from the continuous phase ( concentration or supersaturation measurements ) was still not enough to completely define the system
為此,本文基於阿基米德定律,採用密度法改進了實驗裝置,實現了對結晶過程中溶液濃度或過飽和度的連續在線測量,並提高了測定精度,所測得實驗數據具有較好的重現性。The thesis mainly investigated the bati _ 4o _ 9 ( bt _ 4 ), which has the lowest dielectric loss in ba - ti system, and ( ba, sr ) tio _ 3, the a position substitute compound of batio _ 3. the dielectric properties of bt _ 4 / bst with different preparation way and different elements doping were investigated. a archimedes method, xrd, sem, impedance analyzer, network analyzer and hakki - coleman method were used to investigate the density, phase formation, microstructure, dielectric properties and doping mechanisms
本論文以在ba - ti系中具有最低介電損耗的bati _ 4o _ 9 ( bt _ 4 )高頻介質陶瓷和batio _ 3a位sr取代而得的( ba , sr ) tio _ 3 ( bst )高頻介質陶瓷作為研究對象,對不同粉體制備方法制備的bt _ 4 / bst高頻電介質材料進行不同元素的摻雜,運用阿基米德方法, x射線衍射分析儀,掃描電子顯微鏡和阻抗分析儀,網路分析儀, hakki - coleman法等方法手段和測試儀器測試燒成樣品的密度,相組成情況,微觀結構和介電性能,探討造成介電性能起伏的形成機理。分享友人
