孿生作用 的英文怎麼說
中文拼音 [shēngzuòyòng]
孿生作用
英文
twinning-
When ct20 alloy was tensioned at 20k, the main deformation mechanism in equiaxed microstructure was the slip of dislocations, and in bimodal microstructure the slip of dislocations and a small amount of twinning and in lamellar microstructure a large amount of twinning
Ct20合金20k拉伸變形時，等軸組織主要是位錯的滑移起主導作用，雙態組織除了位錯滑移外還有少量的變形孿晶產生，片狀組織中則能觀察到數量較多的孿晶。It can be noticed that both r and t specimens show initial hardening and subsequent softening at the strain amplitude higher than 0. 8 % and cyclic softening from the beginning to fracture under strain amplitude less than 0. 8 % at room temperature, and the cyclic flow stress was always lower in r specimen than in t specimen at the same strain range
且在相同的應變幅下， t向試樣比r向試樣具有更高的循環流變應力。此外，對r向及t向試樣，低應變幅下呈現出循環軟化現象是因為晶粒旋轉導致循環軟化；而在高應變幅下發生循環硬化是由於孿晶作用的結果。( 3 ) various digital image - processing techniques for suppression of undesired components and enhancement of quality in numerical reconstruction images are considered, such as hologram contrast - enhancement, hro subtraction, mean value subtraction, frequency domain filtering and spectrum expansion with conjugation symmetry property
（ 3 ）從理論和實驗兩方面分析了全息圖對比度增強、平均值相減、 hro 、頻譜濾波等數字圖像處理技術，及其在消除全息圖衍射0級和孿生像，提高數值再現像信噪比方面的作用。
