2) pure virtual function
纯虚函数
1.
In a base class,abstract class is defined by declaring pure virtual function,a derived class must define all inherited pure virtual functions of its base classes to be concrete.
在基类中可以通过将虚函数声明为纯虚函数的手段来定义抽象类,强制派生类在自己的类定义中实现虚函数的具体功能。
3) quadratic imaginary simple algebraic integral domain
二次虚单纯代数整环
1.
In this paper,we extends the integral domain to the quadratic imaginary simple algebraic,integral domain,discusses the reductive factorization of which and the integral domain with the Euclid property,and obtains a part of integral domain which can be factorized uniquely in the quadratic imaginary simple algebraic integral domain.
该文把整数环扩充到二次虚单纯代数整环,讨论了二次虚单纯代数整环的可既约分解性,进一步探讨了具有Euclid性质的整环,从而得到了二次虚单纯代数整环中能够实现唯一分解的一部分整环。
4) pure imaginary spectrum
纯虚谱
1.
The spectrum of infinite dimensional Hamiltonian operators are considered and the sufficient condition for infinite dimensional Hamiltonian operators have only pure imaginary spectrum is obtained.
