The research on size polydisperse LJ liquids in relation to RS liquids was published this year in:T. S. Ingebrigtsen, and H. Tanaka, Effect of Size Polydispersity on the Nature of Lennard-Jones Liquids. J. Phys. Chem. B 119, 11052 (2015). Biman Bagchi Festschrift．Research related to RS liquids and energy polydispersity was initiated and brought the conclusions: 1. Energy polydisperse LJ liquids are also RS liquids, although phase separation tends to destroy the strong UW correlation. 2. Isomorphs are a good approximation also for energy polydisperse LJ liquids.During the year 2015， a competing group published a study on the phase behavior of the energy polydisperse LJ system and our study was thus focused on the connection to RS liquids. This study was described in a draft manuscript but not submitted for publication before the end of the JSPS term.The study related to MRCO of the 2D LJ liquid appeared more difficult than anticipated and was continued thoughout the year but didn't bring any firm conclusions. Additionally, this year, very preliminary studies of a 2D size polydisperse LJ liquid under Couette shear flow were initiated. This very early study leads to the formulation of a project description submitted to the Institute of Industrial Science, University of Tokyo after the JSPS term.

关于尺寸多分散LJ液体与RS液体的关系的研究发表在今年的T.S.Ingebrigtsen和H.Tanaka上，《尺寸多分散对Lennard-Jones液体性质的影响》。J.Phys.化学。B119,11052(2015年)。开展了RS液体和能量多分散性的相关研究，得出以下结论：1.能量多分散LJ液体也是RS液体，尽管相分离倾向于破坏强的UW相关性。2.同构态对于能量多分散LJ液体也是一个很好的近似。在2015年，一个竞争小组发表了一项关于能量多分散LJ体系相行为的研究，因此我们的研究集中在与RS液体的联系上。这项研究是在一份手稿草稿中描述的，但在JSPS期末之前没有提交发表。与2D LJ液体的MRCO相关的研究似乎比预期的更困难，并在这一年里继续思考，但没有带来任何确定的结论。此外，今年开始了对库埃特剪切流动下2D尺寸的多分散LJ液体的非常初步的研究。这项非常早期的研究导致制定了在JSPS任期结束后提交给东京大学工业科学研究所的项目说明。
