管壁曲率 的英文怎麼說
中文拼音 [guǎnbìqūlǜ]
管壁曲率
英文
wall curvature-
The components of the tangential stretch mode of swtns are assigned, the variational curve of the value of ig / id changed with laser power is obtained at 632. 8nm excitation, the vibration of d mode is assigned renewedly
對單壁碳納米管的正切拉伸模的成分進行了歸屬,在632 . 8nm激發波長下得到了ig / io值的隨激光功率變化曲線。重新對d模的振動進行了歸屬。And the conclusion is that vita method is a more reasonable method in burst detection when the threshold value is between 0. 7 to 1. 0. in order to investigate the influence of transverse curvature of the wall, the direct numerical simulated data bank of turbulent channel flow is also analyzed. the mean velocity profile in pipe and channel flow is compared
本文還對圓管和槽道內的猝發事件進行了分析,得到的圓管和槽道內的猝發周期大致是相同的,但是在猝發的強度上槽道要大於圓管;並且進一步的分析表明猝發強度的差別主要在於徑向速度的差別,這說明壁面橫向曲率對于徑向的流動影響較大,而對流向流動幾乎沒有影響。
