16 not only will the tattoo stretch during pregnancy there is no guarantee that the tattoo will go back to its original shape after the birth of your baby
腹部紋身不止在懷孕時會拉伸變形? ?你的孩子出生后它也不能保證可以恢復原樣。The results of quantitative analysis showed that the pre - tension deformation reduced the fatigue crack propagation threshold and increased the crack propagation coefficient, and consequently decreased the fatigue resistance of the part with mechanical damage
定量分析表明：預拉伸變形降低了疲勞裂紋擴展門檻值，提高了裂紋擴展系數，從而使管線在機械損傷的部位疲勞抗力降低。Test results showed that the fatigue crack propagation rare increased with increasing the pre - tension deformation degree, especially at the near threshold section
結果表明：隨著預拉伸變形量的增加，疲勞裂紋擴展速率提高，尤其是在裂紋擴展的近門檻區。In the present study, experimental investigations were carried out on the fatigue crack propagation characteristics of x60 pipeline steel after different degrees of pre - tension deformation ( 5 %, 10 %, 15 % )
摘要用單邊裂紋試樣，研究了x60管線鋼經預拉伸變形量為5 % 、 10 %和15 %后的疲勞裂紋擴展特性。Based on investigating a large amount of documents, the fatigue crack propagation behavior of mg alloys am50 & az91 is studied in this paper, as well as the tensile mechanical properties at elevated temperature. micro - mechanics of tensile deformation and the fcpr are also investigated by sem & tem
本文在查閱大量相關文獻基礎上，對az91 、 am50鎂合金的疲勞裂紋擴展特性和高溫拉伸力學性能進行了一定的研究。藉助于掃描電鏡和透射電子顯微鏡，分析了拉伸變形和疲勞斷裂的微觀機制。分享友人
