繼發變應原
英文
secondary allergen-
Following the analyzing and based on originality of theory, from a angle of view of philosophy of science, in regard to theoretical basis, methodology, and theoretical structure, the author gives a general picture of the original theory of instruction in other countries, and thinks of it as " stones from other hills " that increases the originality capacity of theory of instruction in china, in accordance with the above view, sketches the contours of the paths into generating originally theory of instruction in china, holds that reconstructing medio - theory of instruction is one of feasible orientations of research in theory of teaching and learning in china in future
繼而理性地反思我國教學理論發展與流變的歷程，認為理論移植與依附是近現代我國教學理論原創力貧弱的癥結。論文在原創理論層面上，從科學哲學的視角，分別從理論基礎、方法論、理論結構三個方面探源國外教學理論原創的概貌，作為我國教學理論原創的「他山之石」 ，以此勾勒出我國教學理論實現原創性生成的路徑，認為走教學理論的中層研究是實現我國教學理論原創的應然取向之一。Finally, the random vibration analysis of the signal transform device is presented. experimental modal analysis is discussed briefly. the reasons why the relays on the printed circuit board were destroyed under random acceleration excitations are found out
本文最後對信號變換裝置進行了隨機振動響應分析，簡要探討了實驗模態分析法，找出了裝在印製電路板上的繼電器在隨機振動試驗中被損壞的原因，也介紹了結構動力模型修正技術的發展。It was demonstrated that the values of domain strain decreased while the rate in reduction of the domain strain lowered with larger n. combined the xrd with sem results, the non - fracture mechanism of the sample when pure electric fatigue was applied can be described as : at an earlier stage of electric fatigue, the high repeated incompatible strain led the major fracture mode for the fatigued sample to be of inter - granular. the ability of domain switching in a - - > c of the sample along with the direction of an applied electric field kept dropping, hence, reduced the domain strain
結合xrd和sem觀測，提出了純電疲勞作用下試樣不會發生斷裂的機理：電疲勞初始階段，試樣中的非協調高應變導致沿晶微裂紋，隨著微裂紋的增加，使得試樣沿外電場方向發生a c疇的能力不斷降低，從而導致疇變應變減小，當應變減小到一定程度時，將不足以在試樣中引起新的微裂紋或使原有微裂紋繼續伸長。
