TY - JOUR TI - A short remark on He-Lee’s variational principle for heat conduction AU - Fei Dong-Dong AU - Liu Fu-Juan AU - Wang Ping AU - Liu Hong-Yan JN - Thermal Science PY - 2013 VL - 17 IS - 5 SP - 1561 EP - 1563 PT - Article AB - Tao and Chen claimed that they obtained a new constrained variational principle for heat conduction (Tao, Z. L., Chen, G. H., Thermal Science, 17 (2013), 3, pp. 951-952), however, this short note concludes that it is not new at all. It is equivalent to He-Lee 2009 variational principle.
