起皺現象 的英文怎麼說
中文拼音 [qǐzhòuxiànxiàng]
起皺現象
英文
puckering phenomena-
The mechanisms of such treatment have been proposed as inhibition of proliferation and angiogenesis, as well as induction of differentiation and apoptosis, as has been tested by various in vivo and in vitro experiments. in our experiments, it has also been demonstrated that after the treatment of arsenic trioxide, the k562 cells has undergone major morphological changes, which included nuclear shrinkage, membrane bleb and scattered apoptotic bodies. dna gel electrophoresis also discovered that the typical " dna ladder " phenomena in the treatment group, while the control group showed the regular genomic banding
我們在實驗中觀察到as _ 2o _ 3作用人紅白血病k562細胞后，細胞生長明顯變緩，部分細胞出現皺縮、染色質濃聚及胞膜起泡現象，部分細胞胞膜破裂，在其周圍有緻密的凋亡小體出現， dna電泳出現典型的凋亡「梯狀」帶，提示as _ 2o _ 3能有效抑制k562細胞生長，誘導k562細胞凋亡。There are three types of wrinkle which frequently occur in the sheet metal forming process : flange wrinkling, wall wrinkling, and elastic buckling of the undeformed area owing to residual elastic compressive stresses
在金屬板料成型加工中通常存在三種類型的起皺現象：法蘭起皺，側壁起皺，和由於殘余壓應力在未變形區產生的彈性變形。In this paper, the numerical simulation between using the elastic medium and not using the elastic medium is carried out to analyze the multi - point forming process, and the analysis on the dimple and the wrinkle defects is proposed
本文對使用彈性介質和無彈性介質的多點成形過程進行數值模擬，分析成形過程中產生的壓痕和起皺現象，並對上述缺陷的不同影響因素進行了模擬研究。In this paper, by using non - linear finite element software, ansys / ls - dyna, simulate a forming of auto fall to ground skeleton part, get the contour of the semi - finished product, forecast the change of the blank thickness and the probable wrinkling, cracking, and from the simulation of the spring - back, obtain the spring - back tendency. so, get technology parameters, which are inextricable to forming production. all these will pose great significant to production in theory and reality
本文運用非線性有限元軟體ansys ls - dyna對汽車落地骨架零件進行了沖壓成形的數值模擬，得出了毛坯外形，預測了成形過程中板料壁厚變化和可能出現的起皺、破裂現象，通過回彈模擬，預測了回彈趨勢，獲得了該類零件成形所需要的工藝參數，對實際生產具有一定的指導作用。分享友人
