With the development of science and technology , more and more oxide crystals are synthesized by more and more advanced technique , the new oxide crystals are incessantly synthesized and the new characters of oxide crystals are incessantly founded . corundum dopped with impurity not only is cherished because of it ' s beautiful appearance , but also is used in the fields such as electrotechnics , mechanism , laser , the optic apparatus and the underlay of semiconductor . sapphire dopped with ti3 + is the best material of the tunable solid laser . zno crystal is material of the direct gap semiconductor ( the width of forbidden band : 3 . 37ev ) . the excited emission in zno crystal at room temperature has been found , so the ultraviolet luminescence in zno semiconductor can be acquired at room temperature 含有少量雜質的剛玉晶體( - al _ 2o _ 3 )不僅由于其色澤艷麗成為人們珍愛的名貴寶石,而且由于它具有的優異性能,被廣泛應用于電工、機械、激光器,光學器件和半導體襯底材料。鈦藍寶石是目前最優異的固體寬帶調諧激光材料,用于制作飛秒脈沖可調諧激光器。氧化鋅晶體是直接帶隙寬禁帶半導體材料(禁帶寬度3 . 37ev ) ,現已發現具有室溫下受激發射特性,有可能實現室溫下半導體紫外發光。

A lot of domains are involved with , such as theory of electromagnetism , electrotechnics , electronics , measurement of electromagnetism . signal analysis , mechanics , cybernation , biomedicine , materials , technics , ect . the study of emc is very fargoing and the problem of emc is very complex 它涉及的基礎知識面非常寬廣,直接應用和涉及的知識有電磁場理論、電工原理、電子技術、電磁測量、信號分析、機械結構、自動控制、生物醫學、材料及工藝等等。

In electrotechnics it is found that in the experiment of superposition theorem , there exsists some difference between the experiment resut and its theoretical caculating value , in this paper , the cause for this difference is analysed and a solution to this problem is offered 摘要在電工學中,實驗者在作疊加定理實驗時,發現實驗結果與理論計算值存在著一定的差距,本文分析了產生差距的原因,并提出了解決問題的辦法。

Cooperating the reform in experiment teaching , and associating with the present situation of electrotechnics teaching and experiments in physics major in teachers colleges , and the importance of introducing programmable logic control ( plc ) is used in electrotechnics , and methods are discussed 摘要配合實驗教學改革,結合師范院校物理專業電工學教學、實驗現狀,論述了引進plc的必要性和引進方法。
