漢譯英，求潤色！ 基體的阻尼振幅效應不明顯,阻尼值在1.3左右改變,因此,涂層結構的復雜的阻尼振幅效應應該與基體無關,主要是由涂層引起的。為了便于比較，本文將涂層結構的阻尼值減去基體的阻尼值近似得到涂層的阻尼值.EB-PVD涂層的阻尼振幅效應不太明顯,隨著應變的增加,其阻尼值基本不變。 The damping amplitude effect of the substrate was not obvious, and the damping changed almost nothing , its valve was about 1.3. Therefore, the complex damping amplitude effect should be nothing to do with the substrate and be mainly caused by the coating. For a purposes of comparison, the damping value of coating system minus the one of the matrix was approximated by the damping value of the coating. EB-PVD coating amplitude damping effect is less obvious and the damping value. is essentially equal as the strain increasing. 從公式1可以看出，樣品1的界面處的單位厚度上的缺陷率最高，基于能量耗散基礎，最終使得樣品1的系統(tǒng)阻尼值最高。 As can be seen from Equation 1 , the defect rate of the unit thickness at the interface for the sample 1 was highest, based on the energy dissipation, and ultimately makeed the the system damping of the sample 1 enhace. APS 和 EB-PVD 涂層系統(tǒng)的阻尼有很大的不同，這應該是由于APS 和 EB-PVD 涂層的微觀結構引起的，與基體無關。通過對單獨的APS 和 EB-PVD 涂層進行分析，可以發(fā)現，當應變高于2.0時，APS 涂層的阻尼值有一個很大的增加，而EB-PVD 涂層的阻尼振幅效應卻不太明顯，這應該主要是由于兩種涂層的不同的能量耗散機制引起的。 The damping of the APS and EB-PVD coating system had a significant difference which could be explained by analyzing their two very different microstructures, with nothing to do the substrate. single APS and EB-PVD coating can be found, when the strain is higher than 2.0 , the damping value of the APS coating has a dramatic increase, while the the amplitude damping effect of the EB-PVD coating is less obviously, which should be mainly caused by the different energy dissipation mechanism of the two coatings .

基體的阻尼振幅效應不明顯,阻尼值在1.3左右改變,因此,涂層結構的復雜的阻尼振幅效應應該與基體無關,主要是由涂層引起的。為了便于比較，本文將涂層結構的阻尼值減去基體的阻尼值近似得到涂層的阻尼值.EB-PVD涂層的阻尼振幅效應不太明顯,隨著應變的增加,其阻尼值基本不變。 No obvious damping amplitude effect was observed for the substrate, whose damping value changed slightly near 1.3. Therefore, what accounts for the complex damping amplitude effect should be the coating but the substrate. For comparison in this paper, the approximate damping value of the coating was obtained by subtracting the damping value of the coating from that of the substrate. The amplitude damping effect of the EB-PVD coating is not so evident that the damping value changes little with the strain increasing. 從公式1可以看出，樣品1的界面處的單位厚度上的缺陷率最高，基于能量耗散基礎，最終使得樣品1的系統(tǒng)阻尼值最高。 As can be seen from Equation 1 , Sample 1 has the highest defect rate per unit thickness at the interface and ultimately the highest system damping based on energy dissipation. APS 和 EB-PVD 涂層系統(tǒng)的阻尼有很大的不同，這應該是由于APS 和 EB-PVD 涂層的微觀結構引起的，與基體無關。通過對單獨的APS 和 EB-PVD 涂層進行分析，可以發(fā)現，當應變高于2.0時，APS 涂層的阻尼值有一個很大的增加，而EB-PVD 涂層的阻尼振幅效應卻不太明顯，這應該主要是由于兩種涂層的不同的能量耗散機制引起的。 The damping of the APS and EB-PVD systems displays distinct difference, which could result from the different microstructures of the two coating materials and have nothing to do with the substrate. By analyzing single APS and EB-PVD coating, it can be found that there is a dramatic increase in the damping value of the APS coating when the strain is higher than 2.0, while the amplitude damping effect of the EB-PVD coating is not so obvious, which could mainly be caused by the different energy dissipation mechanisms of the two coatings . |

我這里還有一段話，漢譯英，你能再幫我潤色一下嗎？（只剩下5個金幣了，潤色完后一并都給你了，非常感謝你） 本文中，由于樣品2的熱處理時間要高于樣品3的熱處理時間，因此使得樣品2的彈性模量要高于樣品3的彈性模量。在室溫下，一般認為彈性模量與儲能模量是基本相等的。本文假設界面對涂層系統(tǒng)的模量的貢獻小于涂層對涂層系統(tǒng)模量的貢獻，因此本文認為室溫下樣品2的儲能模量要高于樣品3的儲能模量。在高溫下，如何解釋樣品2的儲能模量要高于樣品3的儲能模量，有待進一步研究。 In this paper, the heat treatment time of the sample 2 is higher than that of the sample 3, so the elastic modulus of sample 2 is higher than that of the sample 3. At room temperature, it is generally believed that the elastic modulus and the storage modulus is substantially equal. This paper assumes that the interface makes a less contribution to the elastic modulus of the coating system than the coating. So that at the room temperature, storage modulus of the sample 2 is higher than that of the sample 3. At high temperatures, it needs to be further discussed that why the storage elastic modulus of sample 2 is higher than that of the sample 3. |

| Sample 2 undergoes longer heating treatment that Sample 3 in the experiment, so the elastic modulus of Sample 2 is higher than that of Sample 3. It is generally believed that the elastic modulus and the storage modulus are substantially equal at room temperature. It’s assumed in this paper that the interface makes less contributions to the elastic modulus of the coating system than the coating. So the storage modulus of Sample 2 is higher than that of Sample 3 at room temperature. Nevertheless, it needs to be further discussed why the storage elastic modulus of Sample 2 is higher than that of Sample 3. |
