Presents the microstructure evolution in aluminum a nd copper after deformation by cold rolling in the strain range of 10 to 50 % red uction using tem and points out three types of dislocation structures are typica l and two of them are common for both materials and these two common types are f ound in non - cube grains and can be distinguished by crystallographic orientatio n of dislocation boundaries in the grains and the third type of structure is obs erved in cube grains, and concludes that grain orientation is important in deter mining the structure type but some other metallurgical parameters also have a ro le to play
採用tem對冷軋多晶銅與多晶鋁的形變顯微組織演變進行了對比研究.結果發現：多晶銅及多晶鋁形變顯微組織中均含有三類典型的位錯結構類型，其中的兩種結構特徵在兩種材料中是相似的，這兩種類型結構存在於非立方取向晶粒，可通過晶粒中位錯邊界的晶體學取向加以區別，另一類型結構存在於立方取向晶粒；晶粒的晶體學取向決定了其形變顯微組織類型，但其它冶金學因素對顯微組織也有影響 -
The image cube provides not only a clear range *. doppler image with superior resolution at each time instant but also the time *. varying history of the images, hence we obtain a good solution to the problem of range spread and image blurring
該方法不僅能給出清晰的瞬時距離-多普勒像，而且能反映目標距離-多普勒像的時間演變特性，較好地解決了目標在距離上的分佈和多普勒像的模糊。 -
As the targets flying in groups may spread over several range of cells and their doppler frequencies are time *. varying, a scheme of target number detection in groups on a conventional low *. resolution radar is proposed based on a time *. range *. doppler image cube which is constructed by substituting a time *. frequency transform for the fourier transform in the conventional range *. doppler imaging
針對實際編隊目標在距離上的分佈特性和目標多普勒頻率的變化規律，利用聯合時頻變換代替傳統傅立葉變換，建立目標時間-距離-多普勒立體像，提出一種基於立體像的目標架次檢測方法。 -
