查询词典 phase transition

Then we studied the double phase transition behavior of three-layer nanostructures with double thermoresponsive shells. Successive RAFT polymerization of NIPAM and 2-ethyl methacrylate or DMA and NIPAM were conducted using PS macroRAFT agent. The PS-b-PNIPAM-b-PDMA and PS-b-PDMA-b- PNIPAM triblock copolymers can self-assemble into PS-core micelles, which possess a three layer \'onion-like\' structure, with PDMA and PNIPAM blocks forming the inner layers or outer coronas.

The results are shown as below.1 Tectono-thermal evolution: The history of the Songliao basin is divides into four stages, high-temperature doming and extension, high-temperature rifting, low-temperature depression, and low-temperature shrinkage. Numerical simulation of mechanical process shows that the basin appeared in the early- to late- Jurassic as a result of rapid low-angle subduction of the Pacific plate towards the northwest, of movement of the Siberian block towards the southeast, of many other influences such as internal thermal stress in the mantle, gravitational force, stress of phase transition, etc. Both the Pacific plate and the Siberian block slowed down in the early Cretaceous, and almost stopped in the middle Cretaceous with the rapid decrease of abnormal heat in the mantle below.

盆地构造热演化力源机制数值模拟研究表明：早、中侏罗世至晚侏罗世晚期，盆地演化主要是太平洋块体向北西方向以低角度快速俯冲和西伯利亚块体向东南俯冲共同作用的结果，同时也与地幔内部热力、重力、相变力以及地球自转及公转速度变化效应和上覆块体绝对运动的作用有关；早白垩世早期至早白垩世中期，来自东部太平洋块体俯冲作用的减弱，而这一时期影响盆地演化的主要力源是地幔内部热力、重力、相变力以及地球自转及公转速度变化效应和来自西伯利亚块体俯冲作用；进入早白垩世晚期至晚白垩世早期，由于双重俯冲带中西侧俯冲作用带基本停止活动，而本区地幔热能的快速衰减则控制盆地的构造热演化；晚白垩世晚期以后，太平洋块体活动加强和地幔热运动是影响盆地演化的主要动力。

The experiment studies revealed Atom Force Microscope observed vital human erythrocytes that incubated at different temperatures in plasma physiological environment, that surface microstructure of the cell membranes were shapely sensitive to the altered temperature increasingly, and that liquid crystalline state bio-membrane were slightly perturbed and happened phase transition. In the optical tweezers experiment, the captive erythrocytes were encaged in the three-dimensional laser optical potential well, and able to well maintain physiology characteristic property and intact shapes.

The third is helpful for people to analyze and explore the unknown things in our universe, such as the evolvement of early universe, the inner structure of neutron stars, the non-conservation of baryons and unclear matter in the university, and so on. QGP is an exploring matter,which comes from hadron matters through deconfinement phase transition. If the existence of QGP is confirmed, not only people will know a new matter, but also a great improvement in the basic physical conception will come.

这可简单概括为：其一是探索在夸克层次上的一种新的物质形态；其二表现在通过对系统集体行为研究进一步检验在夸克层次上的动力学和发展相应的热力学；其三是有助于人们对宇宙中一些未解之谜的分析和研究，如早期宇宙的演化，中子星内部结构，宇宙中的重子数不守恒和暗物质等问题。
