Various hot rolling schedules were applied to a Nb,V,Ti contained HSLA *** temperature had crucial effects on not only yield strength,but also yield ratio and precipitation behavior.600Mpa yield strength is achieved when coiled at 450℃,which is 100Mpa higher than those coiled at 570℃.However,the low coiling temperature had adverse effect to increase yield ratio,which increased from 0.78 to 0.88 as coiling temperature dropped from 570℃ to 450℃.High resolution SEM analysis shows that sizes of Nb,V,Ti precipitates are affected by coiling *** (Nb,Ti)(C,N) precipitates up to 5μm are observed at higher coiling temperature and to decrease tensile strength,where high coiling temperature corresponds to low cooling *** strong cooling and coiling capacity of Shasteel’s 1450mm width hot rolling mill,these results indicate that strength and formability of the steel can be balanced when coiling temperature has been *** and microalloying costs can be reduced by efficiently utilizing the capacity of rolling *** inclusions are found to act as nucleus for Nb,V,Ti precipitates,contributing to coarsening of precipitates.

Noncommutative Chern-Simons Description of the Fractional Quantum Hall Edge

引用

Chinese Physics Letters 2010年第2期27卷 191-194页

作者： HUANG Wei WANG Zhao-Long YAN Mu-Lin Interdisciplinary Center for Theoretical Study Department of Modern Physics University of Science and Technology of China Hefei 230026

Noncommutative Chern-Simons （NCCS） theory is a workable description for the fractional quantum Hall fluid. We apply and generalize the NCCS theory to the physically important case with an edge. Prom relabeling symmetry of electrons and incompressibility of the fluid, we obtain a constraint and reduce the two-dimensional NCCS theory to a one-dimensional chiral Tomonaga-Luttinger liquid theory, which contains additional interaction terms. Further, we calculate one-loop corrections to the boson and electron propagators and obtain a new tunneling exponent, which agrees with experiments.

Tb^(3+)/Sm^(3+)掺杂KY_3F_(10)纳米晶的调制发光和能量转移

引用

人工晶体学报 2015年第12期44卷 3828-3832页

采用水热法合成了未掺杂和一系列Tb^(3+)/Sm^(3+)掺杂KY_3F_(10)粉体。发射光谱表明,在300 nm激发下,Sm^(3+):KY_3F_(10)中Sm^(3+)发光随其掺杂量的增加而减弱;而在Tb^(3+)单掺和Tb^(3+)/Sm^(3+)共掺样品中,Tb^(3+)发光在1mol%~20mol%区间内随其掺杂量的增加而增强。Tb^(3+)/Sm^(3+)共掺样品中存在Tb^(3+)→Sm^(3+)能量转移,最高能量转移效率可达93.70%。由于缺陷发光、交叉弛豫、能量转移的协同效应,无论对于单掺抑或共掺样品,皆可获得暖白光发射。且通过改变掺杂成份或激发波长,可实现基于该KY3F10粉体的蓝、绿、黄绿、黄橙、红橙、粉红等多色发光。
