composites of fields 中文意思是什麼
-
The ag - coated composite powder is a kind of addition agent, which is of great value in the application in the fields of conducting resin, wave - absorbing materials and optical apparatus. the importance of the composites could be attributed to the good associativity between ag and the powder and the equably coating of silver on the substrate
包銀復合粉體作為一種添加劑在導電漿料、吸波材料及光學器件等領域具備很高的應用價值，銀與粉體具備很好的結合性並且能均勻包覆在基體表面達到上述應用要求的一個關鍵。 -
Presents the investigation of the heat conduction behavior, internal thermal stress field of specimen under thermal shock and microscopic damage and failure of the tungsten based composites by combination of macroscopic and microscopic analyses and integration of material science and mechanics ; describes a microscopic mechanical model based on the microstructure of components with macroscopic stress applied to the microscopic model as that of maximum principal stress at the center, and the fringe of the specimen, and the microscopic stress fields obtained through calculation by the finite element method, and concludes from test results that the maximum principal stress is first generated inside the test coupon, and a failure will be first initiated in the inclusion if the material fails at this time ; the maximum principal stress moves to the edge of the test coupon after the test coupon is heated for a period of time, and the failure will first be initiated in the base if the material fails at this time
從材料設計的思想出發，採用宏觀與微觀、材料科學與力學相結合的方法，對鎢基復合材料的熱傳導行為、材料在熱沖擊載荷下的內部熱應力場及材料細觀結構的破壞行為進行了詳細的理論研究.根據鎢基復合材料的細觀組織結構建立了材料細觀模型.在宏觀分析的基礎上，分析了材料微結構內部的破壞行為.分別取試件心部與邊緣主應力值最大點的應力狀態，施加在所建立的模型上，用有限元方法計算了模型內部的彈性應力場.結果表明：試件主應力最大值首先產生在試件內部，此時，如果材料發生破壞將先從夾雜中開始；加熱一段時間后試件中的最大主應力值轉移到試件邊緣，此時材料發生破壞將先從基體中開始 -
