密度熵

  density entropy
     Starting from the extended Skyrme forces, free energy density, entropy density and internal energy density for finite nuclei at finite temperature are derived, from which a series of thermodynamic properties of symmetric and asymmetric nuclear matter are studied. In particalar, we analyse and discuss the nuclear equation of state (EOS) and incompressibility.
     从有限温度有限核的扩展Skyrme力自由能密度,熵密度和内能密度出发,计算了对称核物质和非对称核物质的一系列热力学性质,包括每核子内能、熵、核物质状态方程及不可压缩系数.

In this peper, the image of U. S. landsat MSS is utilized to explain and quantitativelyanalyse the tineament of fine-disseminated-type gold deaits in Qian-Gui Region. It is found that theregional structure can be well-reflected by the variables (density, entropy, dimension).The coincidencerate of known gold deposits with abnomal variables is high(with abnormal demension comes to 80% )

本文利用美国陆地卫星MSS图像对黔桂微细浸染型金矿区的线性体进行了解译,并对其作了定量分析,发现线性体各参量(密度、熵、分维)能较好地反映区域构造,已知金矿床(点)与各参量异常吻合率较高,其中与分维异常吻合率达80%。

Seeing that the traditional entropy has nothing to do with time and can not reflect the basic property of sea wave field under air sea coupling mechanism,the concept of nonequilibrium information theory entropy is introduced to the study on sea wave field.The equilibrium equation of entropy and the specific expressions of entropy density,entropy current density,general force and general force density are derived for the first time.

One and two dimensional combustions in combustors were numerically simulated by Calculation Fluid Dynamics (CFD) . The transmitting processes of temperature pulse, density pulse, entropy pulse, velocity pulse and pressure pulse were studied , and the coupling between the injecting process and acoustic modes was investigated. The results indicate that the transmitting processes of pressure pulse and velocity pulse mainly show acoustic characteristics, while the temperature pulse and density pulse partly show acoustic characteristics, partly show flow characteristics, and the transmitting process of entropy pulse only show flow characteristics. For the combustion instability driven by chemical reactions, the most inspirable acoustic mode is the one whose wave abdomen is the most correlative with chemical reaction distribution.

采用计算流体力学(CFD)方法对燃烧室一维冷流和两维燃烧过程进行了数值仿真,着重研究了温度、密度、熵等变量的脉动与压力脉动的区别,以及喷射过程与声学振型的耦合。结果表明,压力和速度主要表现声特征,温度和密度部分表现声特征,部分表现流特征,而熵则只表现流特征。对于化学反应过程激发的燃烧振荡,最容易受到激发的振型是压力波腹与化学反应分布相关最强的振型。
