The author analyses and studies the development and present situations of chinese foreign trade after china ' s reform and opening - up, changes and characteristics of import and export structure, factors of fast improvement of export structure and problems and conflicts of export structural changes etc. author also rationally considers several relations in export structure and draws the basic conclusion after analyzing and researching : ( 1 ) china has become a big country of international trade but not a powerful country and there is still a long way to catch up with other powerful countries of international trade. ( 2 ) chinese export structure has been in a important adjusting moment in which the direction of chinese export trade development is to preserve the current dimension of non - professional labor - dense products as well as put the main point of further extension on capital - dense, technology - dense and knowledge - dense products. ( 3 ) to realize the upgrade of export structure in china, we must emphasize on orientation of competitive advantage, and convert potential comparative advantage into practical competitive one
通過分析和研究得出的基本結論是： （ 1 ）中國已發展成為世界貿易大國，但是還算不上世界貿易強國，與世界貿易強國相比，尚有很大差距，要成為世界貿易強國，還有很長的路要走； （ 2 ）中國出口商品結構已進入到一個大調整階段，今後中國商品出口貿易的發展方向應該是在保持非熟練勞動密集型產品出口已有規模的同時，將商品出口貿易進一步擴張的著眼點置於資本、技術與知識密集型產品上； （ 3 ）要實現中國出口商品結構的升級，必須以競爭優勢為導向，將潛在的比較優勢轉化為現實的競爭優勢。 -
The opening stress and the life of crack growth is calculated and compared with the test results and the experience formula. the feasibility of the newman theory of opening stress used in the high strength steel is validated. then through the slice synthesis method, the three dimension surface crack of the weld joint of cone - cylinder is decomposed into many plane through cracks
本文將基於裂紋閉合現象建立的帶狀屈服模型，用在平面貫穿裂紋中，計算此時的裂紋張開應力和疲勞裂紋擴展壽命，與試驗結果和經驗公式比較，驗證newman裂紋張開應力理論在高強鋼中的可行性；然後，用切片合成法，把潛艇結構凸錐柱結合殼焊縫處的三維表面裂紋分解成平面貫穿裂紋，用帶狀屈服模型的理論來分析平面貫穿裂紋，得到裂紋沿深度方向的擴展速率，進而得到潛艇結構的疲勞壽命。
