  1. The contents include : based on the previous research and the data of experimentations, the author researches and develops a kind of satisfactory semi - empirical formula of nonlinear temperature distribution, and calculates the temperature stress of rigid - framed arch bridge by the fem. the temperature effects of bridge structure by annual and sunlight temperature difference are discussed, it indicates that the temperature effect of annual temperature difference is small but the temperature effect of sunlight temperature difference is great and the temperature stress along beam depth resulted from sunlight temperature difference is nonlinear. with the comparison between the temperature effects of different position of bridge, the results show that where the section of bridge is small, the temperature stress of it is large

    本文主要包括以下內容:從理論上研究並結合實測資料發展了一種比較理想的半經驗度場非線性分佈公式,並將有限元方法應用於剛架拱橋結構度應力的算中,對橋梁結構進行整體度應力分析;討論了年差和日差引起的橋梁結構的度效應,表明年差引起的度效應較小,而日差引起的度應力較大且沿梁呈非線性分佈;分析比較了橋梁結構各個部位的度效應的大小,可知截面越小度拉應力越大,受力越不利;並對箱梁結構由於構造不同引起的縱向與橫向的度效應大小進行了探討,發現在頂板下緣也會出現當大的度拉應力,並且梗腋的存在反而增加了頂板底部的度拉應力;還對幾種近的剛構式橋型的度效應進行了分析對比,總結了這些橋型針對度效應的優劣,並提出應的針對性措施。
  2. The sample with low emitter efficiency has completed as the method of above. this lead to the greatly decrease of the reverse recovery time and the low reverse leakage and forward voltage, especially the excellent temperature character of the leakage. the test date shows that the samples reach the first class of international level

    本論文作者通過模擬測試,驗證了課題研究的理論設想,並設製作了具有低陽極發射效率結構的壓功率frd ,利用局域鉑摻雜和電子輻結合的壽命控制方式,實現器件反向恢復時間的極大減小,並且反向漏電流、軟度因子、正向壓降等關鍵參數也較理想,且具有極佳的漏電度特性,達到器件綜合性能的優良折衷,達到國際先進水平。
