常見例句雙語例句Plasma transferred arc produces the induced electromagnetic field that makes liquid metal convect in molten pool in the surface metallurgical course.在表面冶金過程中等離子束產生感生磁場，使熔池內液態(tài)金屬產生對流運動。At the same time, we introduce a kind of two dimensional inverse heat conduction problems which do not convect with outer space in doing the compression, and we have got the expected result.同時將一類與外界無熱交換的二維逆熱傳導方程應用到圖像壓縮中，并取得了預期的效果。In chapter 4, we discuss the iterative method of a kind of two dimensional inverse heat conduction problems which do not convect with outer space. We show that these problems are severely ill-posed.第四章探討了一類封閉系統(tǒng)的二維逆熱傳導方程的迭代解法，分析了其極度不適定性，給出了與第三章類似的迭代法并證明了其收斂性和收斂速度。 返回 convect
