熵条件 meaning in English
entropy condition
Examples
- Condition of isentropy
等熵条件 - By the structure of weak entropy solution of corresponding initial value problem and the boundary entropy condition which was developed by bardos - leroux - nedelec , we give a construction method to the weak entropy solution of the initial - boundary value problem
由相应的初始值问题弱熵解的结构和bardos - leroux - nedelec提出的边界熵条件，给出初边值问题弱熵解的一个构造方法。 - Due to the poor regularity of solutions at large time . ( 0 . 2 . 1 ) can not defined in classical way . i , e . , the defi nition of the derivatives at any points has no sense . so it may be rather difficult in the research of classical way and must be defined in weak sense . in order to guarantee the uniqueness of weak solutions , a condition ( entropy inequality ) must be need to pick out " good " solution ( entropy solutions )
由于大时间范围内守恒律( 0 . 1 . 1 )的解表现为很差的正则性，它不能在古典意义下定义，即在每一点下的导数无意义，使得古典办法研究遇到很大困难，它只能在弱意义下定义弱解，但往往这种弱解不唯一，需要某条件限制确保解的唯一性，在数学上称为熵条件，满足该条件的弱解称为熵解。
