It has a consistent class instantiation and inheritance structure and the ability of intercessive structural computationalreflection, which enables it to support safe metaclass programming.
该语言具有协调一致的类对象结构，具备结构化计算反射能力，能够进行安全的元类程序设计。
2
The use of infinite elements for modelling wave radiation eliminates the effects of artificial reflection of waves from finite element boundary, therefore the computational accuracy can be assured.
无穷元的应用消除了波在有限元边界上人为的反射效应，保证了数值解答的计算精度；
3
An algorithm used in numerical simulation along the boundary of a computational domain to absorb all energy incident upon that boundary and to suppress reflection artifacts.
