Commentaries by Philip W.T. Pong, Nongyue He, S.D. Liang, Tao Song, Yuri Gaididei and Sergey Volkov and Alexander Y. Grosberg on my review article (Pang, 2011 [1]) are answered. The validity of Davydov's mechanism of bio-energy transport, the completeness of theory, outstanding problems, the normalization and validity of wave function of the system in Pang' model as well as other related problems are elucidated in detail.

A recent comment on a previously published paper addressed the invalid explanation of the off diagonal interdiflusion coefficients of the beta-Ni(Al,Cr) phase in the Ni-Cr-Al system according to the symmetric property of the thermodynamic matrix. In this paper, the experimental data presented by Hou et al. was reanalyzed and the interdiffusion coefficient matrix was estimated again. The results of the analysis have been discussed in terms of a brief reply to the comments of Liu and Liang. (C) 2010 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.

Based on the best bulk metallic glass (BMG) forming alloy in the Mg-Cu-Y ternary system, we introduced Ag (or Ni) to partially substitute for Cu to improve the glass-forming ability (GFA). The objective of this paper is twofold. First, we illustrate in detail a recently developed search strategy, which was proposed but only briefly outlined in our previous publication [H. Ma, L.L. Shi, J. Xu, Y. Li, and E. Ma: Discovering inch-diameter metallic glasses in three-dimensional composition space. Appl. Phys. Lett. 87, 181915 (2005)]. The protocol to navigate in three-dimensional composition space to land large BMGs is spelled out step-by-step using the pseudo-ternary Mg-(Cu,Ag)-Y as the model system. Second, our ability to locate the best BMG former in the composition tetrahedron allows us to systematically examine, and conclude on, the effects of a given alloying element. The large improvement in glass-forming ability in the Mg-(Cu,Ag)-Y system relative to the based ternary will be contrasted with the reduced glass-forming ability in the Mg-(Cu,Ni)-Y pseudo ternary system. It is demonstrated that the improvement of glass-forming ability requires judicious choice of substitutional alloying elements and concentrations, rather than simple additions of multiple elements assuming the "confusion principle."

对NiTi形状记忆合金纤维拔出的力学模型进行了探讨.在恒温状态下,考虑纤维和基体间的界面摩擦力,分别用两种本构理论,即Tanaka的指数模型和C.Liang的余弦模型,讨论了形状记忆合金纤维在变轴力作用下的拉伸问题.推导了形状记忆合金纤维拔出量的表达式,并给出数值计算结果.由指数模型和余弦模型得到的结果非常吻合,证明了这种理论方法是正确的.

针对TLD算法的特征点无法有效表述目标问题，提出了一种基于角点增强改进的TLD目标跟踪算法。改进算法在跟踪模块加入了对目标表述能力更强，具有光照不敏感性和旋转不变性的 Shi-Tomas 角点作为跟踪特征点。跟踪器运行时，在角点经光流法跟踪和双向误差检测后，利用剩余的稳定角点定位目标窗口。对照结果表明，改进算法在面对目标抖动和形变时可以稳定跟踪；有效抑制因跟踪平滑点造成的漂移现象；提高了跟踪的稳定性。针对 TLD算法跟踪过程中因在线模板积累造成的计算量持续增大、实时性持续降低的问题，提出了一种依据相似度中值的模板判断删除机制。该删除机制在模板积累到设定阈值时运行，根据模板与当前目标的相似度，删除不再具备代表性的模板；调整模板空间并更新模板数目。实验表明，该删除机制在应对模板更新快、持续时间长的跟踪情景时有效降低算法计算量，实时性可提高约20％。
